  	Citation × Citation Citation Abstract Copy Title: Oregon lampreys : natural history, status, and analysis of management issues Author: Kostow, Kathryn Year: 2002, 2008, 2005 Executive Summary The jawless lampreys are remnants of the oldest vertebrates in the world. Oregon has somewhere between eight and a dozen species of these primitive fishes. Their taxonomy is obscure because different species tend to look very similar through most of their life cycle, and they have not been well-studied in Oregon. Lampreys occur in the Columbia Basin, including the lower Snake River, along the Oregon coast, in the upper Klamath Basin, and in Goose Lake Basin in southeastern Oregon. They all begin life in fresh water where juveniles burrow into silt and filter feed on algae. As some species approach adulthood they migrate to the ocean or to lakes where they briefly become ecto-parasites, feeding on other live fishes by attaching to them with sucker disc mouths. Other species remain non-parasitic. In addition to some enigmatic species identities, we generally have very little information about the detailed distributions, life histories and basic biology of lampreys. Lampreys became a conservation concern in the early 1990s when tribal co-managers and some Oregon Department of Fish and Wildlife (ODFW) staff noted that populations of Pacific Lampreys, Lampetra tridentata, were apparently declining to perilously low numbers. Pacific Lampreys were listed as an Oregon State sensitive species in 1993 and were given further legal protected status by the state in 1997 (OAR 635-044-0130). Lamprey status is difficult to assess for several reasons: 1) Most observations of lampreys in fresh water are of juveniles and it is difficult to tell the various species apart, even to the extent that the various species are currently clearly designated; 2) Data on lamprey is only collected incidental to monitoring of salmonids. The design and efficiency of the data collection effort is not always adequate for lampreys; and 3) We have very few historic data sets for lampreys. Therefore we often cannot determine how the abundances and distributions we see now compare with those in the past. The limited data that we have suggests that lampreys have declined through many parts of their ranges. The most precipitous declines appear to be in the upper Columbia and Snake basins where we have some historic data from mainstem dam counts. Pacific Lampreys have declined to only about 200 adults annually passing the Snake River dams. We also have evidence of declines of Pacific Lampreys in the lower Columbia and on the Oregon coast, although our data is quite limited. We have little to no information about any of the other species of lampreys. We are not even sure whether some of the recognized species, like the River Lamprey (L. ayresi), is still present in Oregon. This paper concludes with a Problem Analysis for Oregon lampreys. Our biggest problem is poor information, ranging from not knowing basic species identity to having inefficient or no systematic monitoring of lamprey abundance and distribution. ODFW continued an annual harvest on Pacific Lamprey in the Willamette Basin in 2001, but we lack the necessary information to assess the affects of the harvest on the population. Major habitat problems that affect lampreys include upstream passage over artificial barriers, a need for lamprey-friendly screening of water diversions, and urban and agricultural development of low-gradient flood plain habitats.

This report first outlines the ESA provisions most relevant to the act's impacts on private property, and then surveys the major ESA-relevant principles of Fifth Amendment takings law. The report then proceeds to its core topic: the court decisions adjudicating whether government measures based on the ESA effect a taking of property under the Fifth Amendment. The cases address four kinds of ESA measures: (1) restrictions on land uses that might adversely affect species listed as endangered or threatened; (2) reductions in water delivery to preserve instream flows needed by listed fish; (3) restrictions on the defensive measures a property owner may take to protect his/her property from listed animals; and (4) restrictions on commercial dealings in members of species acquired prior to listing as endangered or threatened. To date, only one of the 12 ESA-based takings decisions revealed by research has found a taking.

Major issues in recent years have included changing the role of science in decision-making, modifying critical habitat procedures, reducing conflicts with Department of Defense activities, incorporating further protection and incentives for property owners, and increasing protection of listed species, among others. In addition, many have advocated enacting as law some ESA regulations promulgated during the Clinton Administration. The ESA has been one of the more contentious environmental laws. This may stem from its strict substantive provisions, which can affect the use of both federal and non-federal lands and resources. Under the ESA, species of plants and animals (both vertebrate and invertebrate) can be listed as endangered or threatened according to assessments of their risk of extinction. Once a species is listed, powerful legal tools are available to aid its recovery and protect its habitat. The ESA may also be controversial because dwindling species are usually harbingers of broader ecosystem decline: the most common cause of listing species is habitat loss. The authorization for spending under the ESA expired on October 1, 1992. The prohibitions and requirements of the ESA remain in force, even in the absence of an authorization, and funds have been appropriated to implement the administrative provisions of the ESA in each subsequent fiscal year. In the 108th Congress, two bills were reported by the House Committee on Resources, but not enacted, that would have amended the ESA to modify scientific peer review and critical habitat procedures. Interior appropriations measures funded Fish and Wildlife Service programs related to endangered species (P.L. 108-108 provided $265 million for FY2004; P.L. 108-447 provided $262 million for FY2005). P.L. 108-136 (Defense authorization) included an ESA amendment to direct that critical habitat not be designated on military lands under certain conditions when Integrated Natural Resources Management Plans are in effect. P.L. 108-137 (Energy and Water appropriations) prohibited use of FY2004 or earlier funds to reduce water deliveries under existing contracts for ESA compliance for the silvery minnow on the Middle Rio Grande River unless water is obtained from a willing seller or lessor; this prohibition appears to have been made permanent by ?205 of Div. C of P.L. 108-447. P.L. 108-148 (Healthy Forests Act) authorized hazardous fuels reduction projects on BLM and national forest lands, including those containing habitat for listed species; directed establishment of a healthy forests reserve program to promote recovery of listed species; and directed the Secretary of the Interior to provide property rights assurances to landowners enrolled in the healthy forests reserve program.

Major issues in recent years have included changing the role of science in decision-making, changing the role of critical habitat, reducing conflicts with Department of Defense activities, incorporating further protection for property owners, and increasing protection of listed species, among others. In addition, many have advocated including significant changes to ESA regulations made during the Clinton Administration in the law itself. The ESA has been one of the more contentious environmental laws. This may stem from its strict substantive provisions, which can affect the use of both federal and non-federal lands and resources. Under the ESA, certain species of plants and animals (both vertebrate and invertebrate) are listed as "endangered" or "threatened" according to assessments of their risk of extinction. Once a species is listed, powerful legal tools are available to aid its recovery and protect its habitat. The ESA may also be controversial because dwindling species are usually harbingers of resource scarcity: the most common cause of listing species is habitat loss. Recent efforts in the House would modify ESA provisions that designate critical habitat, and that provide for scientific peer review. The authorization for spending under the ESA expired on October 1, 1992. The prohibitions and requirements of the ESA remain in force, even in the absence of an authorization, and funds have been appropriated to imple- ment the administrative provisions of the ESA in each subsequent fiscal year. In the 108th Congress, two bills (H.R. 1662 and H.R. 2933) have been reported that would, respectively, address issues concerning scientific peer review and critical habitat. These bills may be brought to the House floor in September. Earlier, P.L. 108-108 (Interior appropriations) provided $265 million for FY2004 for programs related to endangered species. P.L. 108-136 (Defense authorization) included an ESA amendment to direct that critical habitat not be designated on military lands under certain conditions when Integrated Natural Resources Management Plans are in effect.

The act also established an executive committee to oversee the Collaborative Program associated with this situation. P.L. 108-148 (Healthy Forests Act) authorized hazardous fuels reduction projects on BLM and national forest lands including those containing listed species habitat; directed establishment of a healthy forests reserve program to promote recovery of listed species; and directed the Secretary of the Interior to provide assurances to landowners whose enrollment in the healthy forests reserve program results in new conservation benefits for ESA-listed species.

The Lost River sucker {Deltistes luxatus) is a federally listed, endangered fish species endemic to Upper Klamath Lake?a large, shallow hypereutrophic lake in southern Oregon. Sucker population declines in the lake over the past few decades are thought to be partly attributable to extreme water quality conditions, including elevated ammonia concentrations and elevated pH, that occur during summer cyanobacterial blooms. I analyzed structural changes in gills of larval Lost River suckers after they were exposed to elevated pH and elevated ammonia concentrations in chronic toxicity tests conducted in the laboratory. Histopathological changes in sucker lamellae were observed at ammonia concentrations that did not significantly decrease survival, growth, whole-body ion content, or swimming performance. Structural changes that I evaluated included O2 diffusion distance, lamellar thickness, hyperplasic and hypertrophic mucous cells, and infiltration of white blood cells into the lymphatic space. The increases in diffusion distance and lamellar thickness were statistically significant (P < 0.05). These gill changes are indicative of potentially compromised respiratory and ionoregulatory capacity. Because in this species gill structural changes appear to be a more sensitive indicator of stress in eutrophic water quality conditions than are the more traditional sublethal indices, gill histopathology might be useful for monitoring the health of Lost River suckers in Upper Klamath Lake.

The problem is a natural one; it has not been caused by man's carelessness and cannot be turned around by regulation. Upper Klamath Lake is quite shallow, warming rapidly in the summer, and the waters carry a naturally occurring high nutrient load. Algal growth is extensive, predominently APHANEZOMENON FLOS-AQUAE, a blue-green algae prevalent in eutrophic waters. These organisms form dense mats that become very odorous as they decay. Numerous macrophytes (aquatic weeds) are indigenous to the lake, but the major problem is with P0TAM06ET0N CRISPUS, which forms long floating fonds that tangle boat motors and prevent passage. The Pelican Bay channel has an extensive growth of this weed.

  	Citation × Citation Citation Abstract Copy Title: Reproductive biology and demographics of endangered Lost River and shortnose suckers in Upper Klamath Lake, Oregon Author: Perkins, David L.; Scoppettone, Gary; Buettner, Mark Year: 2000, 2005 We analyzed the reproductive biology and demographics of the Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris, two endangered species endemic to the upper Klamath Basin of Oregon and California, from 1984-1997. Lost River suckers had distinct river and lake shoreline spawning stocks, and individuals of both species commonly spawned in consecutive years. In the Williamson River and lower Sprague River, spawning migration by both species occurred mainly during a 5-week period that started within the first three weeks of April and peaked between mid April and early May, although a separate, earlier (mid March) run of Lost River suckers may also spawn in the upper Sprague River. Migration of both species was several times higher at dawn (0500-0730 h) and evening (1800-2200 h) than other times of the day. Peak migrations almost always corresponded to peaks in water temperature, usually at 10-15°C. Lost River suckers were captured at springs along the east shore of the lake from late February through mid May, with peak spawning usually in mid March to mid April. Shortnose suckers were generally captured at the springs from late March through late May, but the time of peak spawning was not determined. Size and age at maturity was determined by recruitment from a strong year class (1991). Male Lost River suckers began recruitment into the adult population at age 4+ (375-475 mm). Substantial recruitment of females did not begin until age 7+ (510-560 mm). Male and female shortnose suckers began recruitment at age 4+, with the majority offish recruited by age 5+. Males recruited at 270-370 mm; females recruited at 325-425 mm. Fecundity estimates were quite variable ranging from 44,000-236,000 eggs per female Lost River sucker and 18,000-72,000 eggs per female shortnose sucker. In 1984 and 1985, the spawning populations of both species were dominated by large, old individuals, with little indication of recent adult recruitment. In the next 13 years, only one strong year class (1991) recruited into the spawning populations of both species. This year class temporarily boosted population numbers, but annual fish kills from 1995 to 1997 eliminated most adults of both species. Associated with poor water quality caused by the proliferation and decay of blue-green algae Aphanizomenonflos-aquae, these fish kills raise concern that alterations to the lake ecosystem over the past several decades have Perkins et al. Lost River and shortnose suckers 5 increased the magnitude and frequency of poor water quality. As a result, mortality rates of all life stages may have increased, thereby disrupting the species' life history pattern and potentially decreasing long-term population viability. Introduction The Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris are large, long-lived suckers endemic to the upper Klamath Basin of Oregon and California. Both species are typically lake dwelling but migrate to tributaries or shoreline springs to spawn (Moyle 1976, Scoppettone and Vinyard 1991). Once extremely abundant (Cope 1884, Gilbert 1898), both species have experienced severe population declines and were federally listed as endangered in 1988 (USFWS 1988). Much of the original habitat of these suckers has been destroyed or altered by conversion of lake areas to agriculture, dams, instream flow diversions, and water quality problems associated with timber harvest, loss of riparian vegetation, livestock grazing, and agricultural practices (USFWS 1988). Knowledge of the life history of Lost River and shortnose suckers is fundamental to recovery of these species. The objective of this report was to present the results of studies conducted from 1987-1998 on the reproductive biology and demographics of Lost River and shortnose suckers, and to compare these results with earlier unpublished data. Study Sites Studies were conducted on Upper Klamath Lake and the lower Williamson-Sprague river system (Figure 1). These waters form the upper portion of the Klamath River Basin in south-central Oregon and represent most remaining native habitat of Lost River and shortnose suckers. Upper Klamath Lake is a remnant of pluvial Lake Modoc that included eight major basins and encompassed 2,839 km2 (Dicken 1980). Today, Upper Klamath Lake serves as a storage reservoir that provides water for agricultural irrigation, waterfowl refuges, instream flow requirements of anadromous fish, and hydroelectric power generation. At full capacity, the lake covers approximately 360 km2 and has an average depth of 2.4 m. Most deeper water (3-12 m) is restricted to narrow trenches along the western shore. Lake elevation is controlled at the outlet by Link River Title: Reproductive biology and demographics of endangered Lost River and shortnose suckers in Upper Klamath Lake, Oregon Author: Perkins, David L.; Scoppettone, Gary; Buettner, Mark Year: 2000, 2005 We analyzed the reproductive biology and demographics of the Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris, two endangered species endemic to the upper Klamath Basin of Oregon and California, from 1984-1997.

Isozyme analysis was not determined to be an adequate method for assessing stock structure in green sturgeon for the following reasons: 1) the complex nature of isozyme expression 2) the relatively poor resolution of enzyme systems for our samples 3) the invasive nature of collecting tissue samples for isozyme analysis, which necessitates sacrificing the fish, precludes collection of samples from some rivers. The stomach contents of 23 green sturgeon collected from fish harvested in the Klamath River were analyzed. Only four stomachs contained identifiable food items, with the others containing food far too digested for identification, gravel, or no contents. Two stomachs contained the small gastropod, Olivellapyna, one stomach contained the carapace remains of a female Dungeness crab, Cancer magister, and one stomach contained the posterior portions of three ammocoetes, Lampetra tridentata. Preliminary analysis was conducted using mtDNA to assess the potential of using this technique for assessing the stock structure of green sturgeon. Although the Klamath River Fishery Restoration Program did not fund this analysis, the results are presented because this work was designed to yield complementary information to the isozyme study. No diagnostic differences were detected between samples collected from the Klamath River and the Columbia River estuary using Restriction Fragment Length Polymorphism analysis. Study results indicated that microsateliite DNA analyst might be the most appropriate current genetic technique for assessing the population structure of green sturgeon.

The 1995 and 1996 survey season marked the third and fourth year that the CCFWO conducted investigations on the upper mainstem Klamath River to derive a reasonable estimate of natural * fall chinook spawners. A total of 339 redds were observed in the 1993 survey. In 1994 and 1995, redd counts increased to a total of 1,702 and 3,240 respectively. During the 1994 and 1995 spawning, seasons, there was evidence that unspawned surplus adult fall chinook salmon released from Iron Gate Hatchery (IGH) successfully spawned in the Klamath River. One hatchery fin clipped adult was observed spawning.30 miles downstream of the hatchery. In 1996, 1,372 redds were observed which wasa decrease of 43% from the previous year. There was complete retention of hatchery origin adults by IGH in 1996, although, the distribution of redds remained the same as previous years. With the new hatchery policy of excess return retention, mainstem escapement can now be considered a reasonable estimate of natural spawning adult chinook salmon. Reddsubstrate composition estimates remained consistent with previous spa- *:g survey data. Based upon 210 redd measurements from 1995-1996, the average redd size L ...e mainstem of the Klamath River was 9.6 nr. The average pit depth, mound depth, and adjacent depth for 1995-1996 was similar to previous survey results. Redds were most common along the wetted channel margins with numerous redds observed in side channels with suitable gravel and water velocities. Unlike 1993 and 1994 some redds were observed by 1995 and 1996 survey crews in rnid-channei areas. Recreational suction dredge mining was present throughout the survey from the confluence of Scott River downstream to the confluence of Indian Creek, although only two redds were observed on recent dredge tailings. Under the existing mining regulations, adverse impacts on redds could occur below the Scon River without protection of spawning areas. Title: Mainstem Klamath River fall chinook spawning Redd survey : fiscal year 1995 and 1996 Author: Catalano, Mark Year: 1997, 2005 ABSTRACT With the decreasing runs of natural fall chinook salmon* Oncorhmchus tshawytscha.inthe Klamath River basin, concerns were raised regarding the accuracy ma significance 01 me mainstem Klamath River .1 chinook spawner estimates. The U.S. Fish and Wildlife Service, Coastal California Fish an - Wildlife Office (CCFWO) was funded through the Klamath River Fish and Wildlife Restoration Act (P.

Investigations began in October 1988, with this reporting period covering October 1991 through September 1992. Adult chinook spawner escapement was addressed by surveys of redds, live fish and carcasses, and by radioteleiretry. Spawner numbers were v?ry low, with only 22 redds observed in fall 1991/winter 1992. The peak count of adult Chinook was 97 fish in early November. Radiotelemetry of migrating spawners (n?8) was used to locate remote spawning areas. Emigrating juvenile Chinook salmon, steelhead trout 10. mvkissV/ coho salmon (fi. kisutchl. and coastal cutthroat trout (g. clarltiV were trapped at river kilometer (rkm) 3.35 with a rotary screw trap (screw trap). The trapping period extended from April to July for a total of 75 trapping nights. Screw trap catches totaled 10,688 chinook, 1,388 steelhead, 99 coho and 10 cutthroat. Peak Chinook emigration occurred during the week of May 17, which is consistent with the past 3 years of monitoring. A juvenile weir was operated 58 nights, and caught a total of 9,166 chinook, 1,196 steelhead, 127 coho and 1 cutthroat. The index of abundance for emigrating chinook during the 1992 juvenile trapping period was 49,590. Sixty-five percent of the juvenile chinook caught during the trapping season were marked with coded wire tags (n-12,687) and released back into Blue Creek at rkm 3.3. Mean water temperatures varied from 6.3 to 18.6 XI and stream flows ranged from 43 to 2178 eft (1.3 to 61.7 m3/?) during the Fiscal Year (FY) 1992 study season.

The objectives of the project include: ? Expanding hands-on field science watershed education. ? Encouraging a sense of resource stewardship among students at all grade levels. ? Collecting quality data for inclusion in the 319h data base. ? Teaching applications of the scientific method. ? Providing on-going inservice training for teachers to increase the effectiveness of the project. Project tasks that were completed include acquisition and analysis of Klamath River Watershed Data, including river water temperatures, river cross sectional profiles and spawning ground surveys. Descriptions of methodology are included in the report. Many other watershed-related projects were undertaken by schools. In some cases the field data was collected and compiled by agency personnel. The spawning ground survey data collected by student volunteers was part of a project conducted by the California Department of Fish and Game and the U.S. Forest Service. Although a substantial amount of excellent work has been accomplished by the schools, the opportunity exists to improve the program at all levels. Increased field and technical support is needed to successfully integrate the goals of the project. Computer training for teachers and students is an essential component of the project, which would allow analysis of data and creation of web sites within classrooms. Data analysis and reporting is the critical component of the project that would provide students with a complete understanding of scientific research methodology. Providing a forum for communication between the 319h participants is another important area of the project that needs to be expanded. Travel time, mountainous topography, and intense winter storms can be barriers to travel in Siskiyou County. Communication helps to increase the level of standardization of data collection and transfer and gives teachers a chance to share successful ideas. Communication also sustains the positive momentum of the project, reinforcing the idea of working as a team towards establishing common goals for watershed education.

  	Citation × Citation Citation Abstract Copy Title: Endangered species consultation handbook : procedures for conducting consultation and conference activities under Section 7 of the Endangered Species Act Author: U.S. Fish and Wildlife Service Year: 1998, 2005 EXECUTIVE SUMMARY Section 7 of the Endangered Species Act (Act) [16 U.S.C. 1531 etseq.] outlines the procedures for Federal interagency cooperation to conserve Federally listed species and designated critical habitats. Proactive Conservation Efforts by Federal Agencies Section 7(a)(l) directs the Secretary (Secretary of the Interior/Secretary of Commerce) to review other programs administered by them and utilize such programs to further the purposes of the Act. It also directs all other Federal agencies to utilize their authorities in furtherance of the purposes of the Act by carrying out programs for the conservation of species listed pursuant to the Act. This section of the Act makes it clear that all Federal agencies should participate in the conservation and recovery of listed threatened and endangered species. Under this provision, Federal agencies often enter into partnerships and Memoranda of Understanding with the Fish and Wildlife Service (FWS) or the National Marine Fisheries Service (NMFS) for implementing and funding conservation agreements, management plans, and recovery plans developed for listed species. Biologists for the Services should encourage the development of these types of partnerships and planning efforts to develop pro-active approaches to listed species management. Avoiding Adverse Effects of Federal Actions Section 7(a)(2) states that each Federal agency shall, in consultation with the Secretary, insure that any action they authorize, fund, or carry out is not likely to jeopardize the continued existence of a listed species or result in the destruction or adverse modification of designated critical habitat. In fulfilling these requirements, each agency must use the best scientific and commercial data available. This section of the Act defines the consultation process, which is further developed in regulations promulgated at 50 CFR ?402. The Handbook This handbook was primarily developed to aid FWS and NMFS biologists implementing the section 7 consultation process. The purpose of the handbook is to provide information and guidance on the various consultation processes outlined in the regulations. Additionally, the handbook will ensure consistent implementation of consultation procedures by those biologists responsible for carrying out section 7 activities. Chapters of the handbook deal with major consultation processes, including Informal, Formal, Emergency, and Special Consultations; and Conferences. Standardized language is provided for incorporation into Biological Opinion documents to achieve consistency and to ensure that all consultation documents are complete from a regulatory standpoint. Background information and example documents are provided in Appendices. Although primarily targeted towards employees of the Services, other groups participating in the consultation process, including other Federal agencies; State, local, and tribal governments; and private individuals, consultants, and industry groups should find the handbook helpful in explaining section 7 processes and providing examples of various types of consultations. This handbook will be updated periodically as new regulations and policies are developed affecting implementation of the section 7 regulations, or as new consultation or assessment techniques evolve, and as additional examples or graphics become available. The Washington Offices of the Services have the lead for preparation of the handbook. Regional offices are encouraged to develop example documents appropriate for their geographical area and individual situations, and to coordinate with other Federal and State agencies in distributing these documents. Consultation Framework Use of Sound Science An overriding factor in carrying out consultations should always be the use of the best available scientific and commercial data to make findings regarding the status of a listed species, the effects of a proposed action on the species or critical habitat, and the determination of jeopardy/no jeopardy to listed species or destruction or adverse modification/no destruction or adverse modification to designated critical habitats. The Services have jointly published a policy on Information Standards Under the Endangered Species Act [59 FR 34271 (July 1, 1994)]. This policy calls for review of all scientific and other information used by the Services to prepare biological opinions, incidental take statements, and biological assessments, to ensure that any information used by the Services to implement the Act is reliable, credible, and represents the best scientific and commercial data available. Flexibility and Innovation The section 7 process achieves greatest flexibility when coordination between all involved agencies and non-Federal representatives, and the Services, begins early. Often, proposed actions can be modified so there is no need for formal consultation. The Services should ensure that all information needed to make an informed decision is made available. It is particularly critical when formal consultation begins that all parties are fully involved in providing information and discussing project options. Although it is the responsibility of the Services to make the determination of jeopardy or destruction/adverse modification in the biological opinion, action agencies and applicants should be fully informed and involved in the development of Reasonable and Prudent Alternatives, Reasonable and Prudent Measures, and Terms and Conditions to minimize the impacts of incidental take. Biologists should be creative in problem solving and look for ways to conserve listed species while still accommodating project goals. Coordination The Services have a policy to ensure coordination with State Agencies for gathering information in implementing the consultation program. [59 FR 34274-34275 (July 1, 1994)] The Services have a joint policy on coordination with tribal governments. Secretarial Order #32306 (June 5, 1997) entitled "American Indian Tribal Rights, Federal-Tribal Trust Responsibilities, and the Endangered Species Act" recognizes that the consultation process should include input from affected tribal governments. State and tribal government biologists often have information available that is pertinent to the description of the action area or to the species of interest in the consultation. Shortening Timeframes Recently, the Services have been implementing measures to streamline consultation processes. Examples include projects reviewed under the Northwest Forest Plan and nationwide Timber Salvage Program. These procedures have been able to effectively shorten consultation timeframes without giving up any protection for listed species/designated critical habitats or the use and review of the best available information. This has been achieved through enhanced interagency coordination, development of guidelines for implementation of a larger program (i.e. timber salvage) which can tier to an individual project (timber sale), and by providing consultation simultaneously with project analysis under the National Environmental Policy Act (NEPA). Biologists for the Services are encouraged to review examples of these streamlined consultations and to look for ways to incorporate streamlining techniques into other consultation procedures.

The lamprey population was later recognized to be a distinct species, Lampetra minima ( Bond and Kan 1973). It was the smallest lamprey species in the world ( maturing at less than 4 in), and at that time was known only from Miller Lake, where it was extinct In 1992, a small lamprey caught in the Upper Williamson River was identified as a Miller Lake Lamprey, and subsequent investigations have identified six local populations of this lamprey in two small subdrainages of the Upper Klamath Basin. Management strategies to preserve this species include: conserving appropriate habitat conditions and availability within the natural range of the Miller Lake Lamprey, addressing potential impacts from stocking streams with hatchery fish, reducing entrainment, and establishing connectivity within and between local populations. A man- made barrier built in 1959 still exists on Miller Creek. Originally created to prevent the re- establishment of lamprey in Miller Lake after the chemical treatment, the barrier currently prevents natural dispersal of the Miller Creek population and re- colonization of both extensive habitat in upper Miller Creek and Miller Lake itself. Removal of the barrier, which is in disrepair but continues to exclude lamprey, is feasible and will eliminate the only man- made feature obstructing natural connectivity within the Miller Lake drainage, the species' type locality. This conservation plan is intended to provide guidance for management actions and conservation of the Miller Lake Lamprey. Introduction lhe Miller Lake Lamprey, Lampetra { Entosphenus) minima, is the worlds smallest predatory lamprey, reaching a size of only 3- 6", and is endemic to the Klamath Basin ( Bond and Kan 1973, Gill et al. 2003, Lorion et al. 2000). It is also one of the few species to have " recovered" from extinction. Miller Lake was chemically treated with toxaphene by the Oregon Game Commission on September 16,1958 to eliminate Tui Chub ( Siphateles bicolor) and a population of unidentified lamprey ( Gerlach 1958, Gerlach and Borovicka 1964). The lamprey in Miller Lake was later discovered to have been a unique species, apparently restricted in range to the Miller Lake drainage ( a small, disjunct tributary to the Upper Williamson River), and was scientifically described by Bond and Kan ( 1973) fifteen years subsequent to its presumed extirpation. Public Review Draft 4- 27- 05 Although there appear to be no immediate threats to the Miller Lake Lamprey ( Kostow 2002), the species is of considerable conservation concern due to: 1) its relatively limited range in two small sub drainages of the Klamath Basin, 2) its continued absence in the ecologically unique setting of Miller Lake ( type locality) and 3) its evolutionary distinctiveness as the smallest known predatory lamprey in the world, maturing at less than four inches. Life History Distribution - The Miller Lake Lamprey is currently known from only two small sub- drainages of the Upper Klamath Basin, the upper Williamson River and the upper Sycan River above Sycan Marsh ( Lorion et al. 2000). The upper Williamson River contains four known populations ( Miller Creek, Jack Creek, Klamath Marsh, and mainstem Williamson River above the marsh). Miller Creek, which drains Miller Lake, is within the upper Williamson Watershed, but it goes sub- surface in the pumice soils and does not reach the Klamath Marsh or Williamson River. Miller Lake has presumably been isolated from the rest of the drainage since the eruption of Mt. Mazama ( Crater Lake) over 6,000 years ago. Jack Creek, a small northern tributary to the upper Williamson River, is also generally disjunct from the mainstem Williamson River due to low, intermittent surface flows in its lower reaches. The Upper Sycan drainage ( a northern tributary of the Sprague River) contains two principal populations, Long Creek drainage and the upper Sycan River drainage above Sycan Marsh. Lamprey have been documented in Coyote Creek and Shake Creek above Sycan Marsh by Nature Conservancy. Lamprey in Shake Creek have not been identified to species. Geographic Variability - In general, individuals from the modern Williamson and Sycan sub-drainages are morphologically similar ( Lorion et al. 2000). However, there are indications of geographic differences between populations. The Sycan populations exhibit significantly higher variability in the number of bicuspid posterial teeth, and the Miller Creek population generally tend to be darker on their ventral surface. Specimens from the original Miller Lake population ( pre- 1958) had, on average, fewer anterial teeth. They also tended to have larger eyes and oral disks relative to total length when compared to modern populations; however, this appears to be due to their slightly smaller size. The available genetic information also indicates that there are geographic differences in the mitochondrial genome ( mtDNA) between Sycan ( Sprague) and Williamson lamprey populations, with one haplotype found only in the Upper Sycan and another limited to lamprey populations in the Sprague River drainage ( Lorion et al. 2000). Continued genetic work on the Klamath lamprey fauna, examining additional genes, indicates that the population of lamprey in Miller Creek may be genetically different than both the other upper Williamson and Sycan populations ( Docker pers. com. 2004). Habitat - Miller Lake Lampreys currently occupy relatively cool, clear streams ( Gunckel and Reid 2004, Kan and Bond 1981, Lorion et al. 2000, Reid pers. com. 2004). Adults are generally associated with structural cover, including loose rocks and woody debris. In lower Miller Creek, where rocky habitat is limited, adult lampreys were consistently found in woody debris jams and even under seat boards from an old outhouse that had fallen into the creek ( Reid pers. obs. 1998). Ammocoetes ( a larval stage lasting about 5 years) live in the substrate and are generally Public Review Draft 4- 27- 05 associated with depositional environments. In streams, ammocoetes are frequently found in silty backwater areas, low energy stream edges, and in pool eddies where leaf litter and other organics ( including adult lamprey carcasses) tend to accumulate. At night ammocoetes may move into the water column to disperse downstream or into more favorable habitat. In Miller Lake ammocoetes were found in organic detritus all along the shoreline but rarely in the extremely cold tributaries flowing into the lake ( Kan and Bond 1981). Recent extensive collections of Pacific Lamprey ammocoetes along the coast indicate that ammocoetes do not occupy otherwise apparently suitable sediments if the upper layer is poorly oxygenated ( Reid and Goodman pers. obs. 2004). Reproduction - Miller Lake Lampreys spawn in shallow redds in clean gravels and sand, which are moved out of the redd by lamprey sucking onto small rocks and actively moving them out of the way ( Markle pers. com. 2004, Reid pers. com. 2004). In streams, redds are generally made in shallow water, often at the tail of a pool or run, and are roughly 10 cm in diameter and a few centimeters deep. In Miller Lake, lampreys were observed spawning in water as deep as 20 feet ( Cochrun 1951b, Kan and Bond 1981). Males attach to the female's head and wrap around her body, aligning genitals and allowing fertilization of the eggs as they emerge. Eggs are heavier than water and are mixed into the bottom of the redd by spawning actions. Kan and Bond ( 1981) found that female lampreys from Miller Lake contained an average of about 600 eggs. Time to hatching is not known, but is probably on the order of a few weeks. Larvae ( ammocoetes) emerge at about 8 mm and move into fine sediments. Adults die after spawning. Feeding - Miller Lake Lampreys feed on fish only as adults. Ammocoetes have no eyes or teeth and are purely filter feeders, burrowing in the sediment and feeding on suspended microorganisms and algae. The ammocoete phase lasts about five years, during which time the ammocoetes grow to around 150 mm. After transformation, adults enter a predatory phase before spawning that generally lasts for less than a year ( from transformation in the summer/ fall to spawning in summer of the following year). Adults feed primarily on flesh that is gouged and rasped out of a small wound (<= 11 mm) under the sucking disk ( Cochran 1994, Kan and Bond 1981). Adults apparently show little selectivity for prey. The adult lampreys in Miller Lake historically fed on both tui chubs and available salmonids ( rainbow, brook and juvenile brown trout) in Miller Lake ( Kan and Bond 1981). They also scavenged dead tui chubs and trout, as well as cannibalizing other lampreys. In Miller Creek, most recent observations found occasional lamprey wounds on brook trout, which were the most abundant species in the creek, but it is probable that lampreys also feed on both rainbows and young brown trout in the creek ( S. Reid pers. obs. 1998). In Jack Creek lampreys feed on speckled dace, the only other fish present in the stream, and in the Upper Sycan they feed on both trout and dace. Unlike other predatory lampreys, but similar to non- feeding brook lampreys, adult Miller Lake Lampreys loose body length and mass between the time they transform and actual spawning, indicating that energetic needs and gonadal development are not compensated for by the amount of food they consume ( Hubbs 1971, Kan and Bond 1981, Lorion et al. 2000). Lamprey / Trout Interaction - Although there have been no direct studies of the ecological interaction between lampreys and trout in the Klamath Basin, it is notable that healthy trout and lamprey populations coexist throughout the basin. Lampreys certainly prey on trout, and both adult lampreys and ammocoetes may represent a significant food resource to piscivorous adult Public Review Draft 4- 27- 05 trout. Native redband trout co- exist with much larger predatory lampreys (" Klamath Lake Lamprey", Lampetra { Entosphenus) sp., and Klamath River Lamprey, L. ( E.) similis) in Upper Klamath Lake. A large percentage of the trophy redband trout in Upper Klamath Lake, as well as both redband and brown trout in the Wood and Williamson Rivers, exhibit recent or healed lamprey scars. In smaller streams where Miller Lake Lampreys ( length 3- 6 in) co- exist with native and introduced trout ( redband, bull, brook and brown trout), there appears to be little impact to adult trout, and local fishermen are rarely even aware of the presence of the lamprey ( S. Reid, pers. comm. 2004, R. Smith, pers. comm. 2004). Surveys by USFWS and USFS in 1998- 1999 found that very few of the trout in Miller Creek, the Williamson or upper Sycan Rivers had scars, and during extensive snorkeling surveys, only a few trout were actually observed with lampreys attached ( S. Reid USFWS pers. com., 2004). Historical reports from Miller Lake prior to the extirpation of lampreys indicate that tui chubs were the principal prey, and dead tui chubs were often reported ( Cochrun 1951a, b, Gerlach 1958, Kan 1975, Kan and Bond 1981). Some cannibalism on other lampreys, as well as scavenging of dead fish carcasses, was also observed ( Kan and Bond 1981). Specific mortality of adult trout was not reported, although large trout were noted to have collections of scars and some mortality of fingerlings was observed. Recent observations of occasional fingerling trout mortality and much more frequent lethal predation on speckled dace (< 10 cm TL) in the Sycan River and Jack Creek, as well as the observation of apparently healthy adult trout with healed wounds, suggests that lethal predation on trout is generally limited to fingerlings ( Markle pers. com. 2004, Reid pers. com. 2004, Smith pers. com. 2004). It is not believed that predation on Miller Lake lamprey by piscivorous adult trout has been a threat to the sustainability of lamprey populations. These populations have co- evolved with native trout and appear to be productive enough to withstand some level of predation. The Jack Creek population is an exception. Jack Creek is believed to only support populations of Miller Lake lamprey and speckled dace. Since this lamprey population evolved absent predation from trout, there is a concern that an introduction of piscivorous adult trout could upset the ecological balance in Jack Creek and present a threat to both the lamprey and dace populations. For this reason, stocking of hatchery fish is prohibited by rule in Jack Creek or other streams containing Miller Lake lamprey. Miller Lake Fisheries - Miller Lake currently supports a recreational trout fishery of entirely introduced species. Miller Lake's one notable native species, the Miller Lake Lamprey, was thought extinct when the Oregon Department of Fish and Wildlife Commission approved the current Klamath Basin Fish Management Plan ( ODFW 1997). Today, Miller Lake provides a popular " catchable" and fingerling rainbow trout program, a trophy brown trout fishery, and an under- utilized kokanee population of small- sized individuals ( Smith pers. com. 2004). Due to the role of Miller Lake as a recreational fishery and concerns over the potential impact of lampreys on introduced trout populations in the lake, the history and status of Miller Lake fisheries are summarized below by species. Rainbow trout fingerlings ( 2- 4 inches) were planted in Miller Lake until 1948, when stocking was discontinued due to poor returns. At that time, the poor rainbow fishery was believed to have been due to lamprey predation and competition with resident tui chubs ( Cochrun 1950, Public Review Draft 4- 27- 05 1951a). However, based on the reported poor performance of stocked fingerling rainbows post-treatment ( see below), without either lampreys or tui chubs, it appears that local habitat conditions, and not trophic competition with tui chub or parasitism by lamprey, were driving the poor rainbow population dynamics. Recent observations by ODFW biologists have indicated that while the rainbow trout in Miller Lake are surviving, growing and being harvested by anglers, survival and growth have been, at best, marginal ( Smith pers. com. 2004). Trapnet samples in Miller Lake have been very inefficient at capturing older age class rainbow trout so the average size of sampled trout is not representative of the fish that are available for angler harvest. While trapnet sets typically made in the fall are not particularly good indicators of the rainbow population in Miller Lake, Trapnet sampling of rainbow trout documented an average length of approximately 8 inches in 1988 and approximately 4 inches in 1997. The release of catchable- sized rainbow trout into Miller Lake was initiated in 2001 to supplement the ongoing fingerling stocking program. Brown trout were first introduced into Miller Lake in 1981 and have been stocked annually since. Although small numbers may have been present prior to treatment. Survival and growth of brown trout has been excellent ( Smith pers. com. 2004). Brown trout averaged approximately 17 inches in length in 1998 and approximately 16 inches in 2001. Larger fish captured in trap net sets exceed 10 pounds. Miller Lake was identified by sport- fishing author Denny Rickards as one of the top ten brown trout producing lakes in the western United States. Lampreys themselves, as well as their impaired prey, might in turn serve as additional prey for the large, highly piscivorous brown trout. Stocks of kokanee were introduced to Miller Lake from several states between 1964 and 1971 ( all post- treatment). Kokanee have been very successful reproducing and stocking has not been necessary since 1971. The average size of maturing adults have remained relatively small. Miller Lake is an oligotrophic lake with very low productivity ( Johnson et al. 1985). The length of maturing female kokanee ranged between 7.5- 10 inches between 1965 tol972, and the average size of kokanee females in 2001 was approximately 8 inches. Based on the relatively small length of maturing kokanee females, it appears that environmental conditions or interspecific competition with other trout are driving the kokanee population dynamics. Brook trout were stocked in Miller Lake from the 1930' s until 1948. Brook trout were present in Miller Creek and apparently survived in tributaries during the 1958 treatment, since seven brook trout ( 6- 14 in) were gill- netted from the lake in 1964, prior to introduction of 85,000 kokanee and 150,000 rainbow fingerlings. No brook trout are currently stocked into the lake or tributaries of the lake. A healthy self- sustaining population of brook trout is currently present in Miller Creek, below the lamprey barrier, where they have apparently coexisted with lampreys since both recovered from the 1958 treatment. Tui chubs were present in Miller Lake prior to the 1958 treatment. It is not known whether tui chub were a native or introduced population. However, based on the elevation and atypical tui chub habitat in the lake, it is believed to have been an un- authorized introduction, most probably as a baitfish. Trophic competition between tui chub and rainbow trout has been consistently demonstrated in several Oregon lakes, including Diamond Lake in Douglas County. Tui chub or " roach" problems in Miller Lake were identified by Ken Cochrun ( Fisheries Agent, Oregon State Public Review Draft 4- 27- 05 game Comm.) in his 1950 and 1951 annual reports ( Cochrun 1950, 1951a). However, Mr. Cochrun felt that the " large population" of tui chub would be relatively easy to control compared to the lamprey and hence the need for the radical chemical treatment with toxaphene, which would eliminate both species, rather than rotenone, which would have limited effect on the lamprey ammocoetes in the substrate. In the 1950' s, as is still the case, considerable amount of time was expended by fishery districts controlling tui chub (" roach"), as noted in Mr. Cochrun's annual reports. Tui chubs were never restocked after the treatment and are no longer present in the Miller Lake drainage. One of the goals of this conservation plan for the Miller Lake Lamprey is to re- establish a lamprey population in Miller Lake itself. Historical reports from Miller Lake prior to the extirpation of lampreys nowhere mention specific mortality of adult trout, even when lamprey were abundant, although large trout were noted to have collections of scars ( see above - Lamprey/ Trout Interaction). Based on historical accounts and recent observations from the Upper Sycan drainages, mortality when observed has been on small fish (< 10cm TL). Observations from Miller Lake in the past and recent observations of trophy redband trout fisheries in Upper Klamath Lake indicate that little to no effect is experienced by the fish based on the occurrence of healed lamprey scars. Self- sustaining populations of brown and brook trout ( unstocked) currently coexist with lampreys in Miller Creek below the lamprey barrier. Were lamprey to become reestablished in Miller Lake, they would probably feed primarily on juvenile kokanee, which are abundant in the lake. Although lamprey predation on adult trout may result in some stress and condition loss, the principal effect on adult kokanee and trout fisheries in Miller Lake is likely to be aesthetic, with small round wounds (< l/ 2 in), or scars, on the side of fish. Future Recreational Fish Management The recreational trout and kokanee salmon fisheries in Miller Lake are an extremely valuable fish resource to local community and anglers. All efforts will be made by the Oregon Department of Fish and Wildlife to continue to offer angling recreation at current harvestable levels. In the unlikely event that the re- establishment of the Miller Lake lamprey adversely impacts the trout and kokanee population abundance, then additional fish stocking or other compatible management actions will be initiated as necessary to meet recreational fishery management objectives. Conservation Plan Note: Underlined, bold text in italics represents those portions of the conservation plan that are proposed to be adopted into Oregon Administrative Rule by the Oregon Fish and Wildlife Commission. Purpose This conservation plan is intended to provide guidance for management actions and conservation of the Miller Lake lamprey, Lampetra ( Entosphenus) minima. This is the first step in securing populations that currently exist in the Klamath Basin and in Public Review Draft 4- 27- 05 determining their status, abundance, distribution, and life history needs. As new information on the lamprey becomes available it is expected that this document will be modified and updated to reflect the current state of our knowledge. Species Management Unit and Population Description The Miller Lake Lamprey species management unit is comprised of six documented populations and one uncertain population. They are: • Mainstem Upper Williamson River above Klamath Marsh • Miller Creek • Jack Creek • Sycan River above Sycan Marsh • Long Creek • Coyote Creek • Shake Creek ( lamprey present have not been identified to species) Desired Status The desired status of the Miller Lake lamprey is for the species to be distributed widely throughout its historic range, with populations robust enough to withstand stochastic environmental events, and with both the populations and their habitat secure from anthropogenic threats. Current Status The Miller Lake Lamprey is endemic to the Klamath Basin and was recently re- described ( Lorion et al 2000). It is currently known from two sub- drainages. The Williamson River sub- drainage includes populations in Miller Creek, Jack Creek, Klamath Marsh and the mainstem upper Williamson River. In the Sycan sub- drainage the lamprey exists in Long Creek and in the upper Sycan River above the Sycan Marsh. Information regarding the abundance and population structure of Miller Lake lamprey in these systems is not available, and only anecdotal information is available for the life history or habitat requirements of the species. For detailed information on the current information available for the species see Life History section. No immediate threats to the Miller Lake Lamprey are known to currently exist, except for the barrier to connectivity between Miller Creek and Miller Lake. Public Review Draft 4- 27- 05 Management Strategies The short- and long- term management strategies for the Miller Lake Lamprey species management unit are: Short- term Strategy a) Re- establish connectivity to Miller Lake. Long- term Strategies b) Ensure appropriate habitat conditions and availability within the natural range of Miller Lake lamprey. c) Reduce entrainment or the potential for entrainment of adult and larval lampreys into water diversions. d) Reduce stranding or the potential for stranding of larval lampreys in dewatered segments of streams below water diversions. e) Maintain unobstructed opportunities, within and among populations for genetic exchange, natural dispersal or migration activities, and re- colonization of unoccupied portions of historical habitat. f) No hatchery fish shall be stocked in streams that support Miller Lake lamprey. Management strategies are those general conditions relevant to the conservation of the species that are considered essential to ensure its long- term survival within its natural range. Although there are many aspects of a species life- history and management that may play a role in the species' biology, the management strategies include those aspects that are currently considered to be both essential for its long- term survival and that are potentially at risk. Conservation Actions Conservation actions are those specific activities or projects that have been identified as appropriate for the realization of the above conservation goals. General - Due to the general lack of information about the life- history, habitat requirements, and distribution of the Miller Lake Lamprey, any studies which increase our understanding of the species will contribute to future conservation planning and should be supported. Habitat - At this time, the general habitat requirements of the Miller Lake Lamprey populations in the upper Williamson and upper Sycan drainages appear to be similar to those of the native trout populations, and habitat restoration or enhancement projects that benefit the trout populations should be beneficial to the lamprey as well. However, there may be specific differences between these species that should be considered in future projects as our understanding of the lamprey's life- history increases. Public Review Draft 4- 27- 05 Entrainment - At this time there has been no evaluation of potential entrainment risks to the Miller Lake Lamprey. Unscreened or improperly screened irrigation diversions currently exist on the upper Sycan and upper Williamson River systems. Private irrigator participation into the screening program should continue to be encouraged and supported. Stranding - At this time there has been no evaluation of potential stranding risks to the Miller Lake Lamprey. Current water diversions reduce the stream flow in segments of the streams directly below the diversion point. Minimum stream flows or gradual ramping strategies should be encouraged where practicable. Connectivity - The Miller Lake Lamprey is not known to carry out extensive spawning migrations. However, due the tendency for ammocoetes to drift downstream during the multi- year larval stage, it is essential that local populations have free upstream passage opportunities during the period when adults are residing in the stream. The swimming characteristics and passage capabilities of trout ( for whom many fish ladders are designed) and lamprey are very different. Lamprey- friendly ladders or passage corridors should be encouraged in the design phase of new projects, and occupied lamprey streams should be evaluated for the presence of older fish ladders, as well as other artificial barriers. Re- establishment of the Miller Lake population - Miller Lake itself, the type locality for the species, remains the only known historical habitat from which the Miller Lake Lamprey is known to have been extirpated. It also represents both an ecologically unique habitat and a crucial component in the evolutionary legacy of the species. Following the extirpation of lampreys from Miller Lake in 1958, a lamprey barrier was constructed in Miller Creek to prevent recolonization of the lake from Miller Creek. The barrier remains in place today. Removal of this barrier should have a high priority in order to meet the conservation goals for the Miller Lake Lamprey and is discussed in more detail below. The barrier was constructed by the State of Oregon Game Commission in 1959 at the upstream extent of a short, high- gradient cascade in Miller Creek approximately 54 mile downstream from the outlet of Miller Lake and forest road 9772. It consists of a low stonework dam ( about 2 ft high) constructed of mortared native rocks, with a metal plate and lip bolted on top. The configuration is very effective as a man- made barrier to fish passage. However, the current condition of the concrete and rock structure is substantially deteriorated. A recent examination by ODFW, USFWS and USFS personnel indicates that the structure would be relatively easy to remove using hand tools without adverse instream impacts ( evaluated by R. Smith et al., September 2003). Recent baseline surveys ( August 2004) of lamprey ammocoetes in the Miller drainage indicate that they are apparently limited to less than two miles of low- gradient stream in lower Miller Creek ( Gunckel and Reid 2004). Allowing lampreys to re- establish a population above the cascade in Miller Creek and Miller Lake will aid in creating an additional buffer against stochastic events that could otherwise eradicate this geographically limited population. Additional surveys should be scheduled on a five- 10 Public Review Draft 4- 27- 05 year basis to evaluate status of the population and the success of re- colonization efforts. Removal of the barrier should allow natural expansion of the population and recolonization of the lake from the Miller Creek population, which survived the original extirpation. Information Gaps 1) Life history - very little quantitative information is available on the life history and habitat requirements of either ammocoetes or adults with which to guide management decisions. 2) Distribution - current understanding of distribution is based on surveys in the 1990' s that primarily focused on the Williamson and Sprague River drainages. Other potential areas in the Klamath Basin outside these drainages have not been properly surveyed. 3) No specific population or fine- scale distributional surveys have been undertaken for any populations outside of the Miller Lake drainage. 4) Preliminary morphological and genetic information suggests that there are regional differences between the various populations of Miller Lake Lamprey in the Klamath Basin. However, the available information is not yet sufficient for making management decisions relative to population independence or uniqueness. Strategies to Address Gaps 1) A Miller Lake Lamprey Technical Management Team has been formed to promote investigation, management and conservation of the Miller Lake Lamprey. This team currently consists of biologists from ODFW ( Roger Smith and Stephanie Gunckel), Oregon State University ( Douglas Markle), the Western Lamprey Project ( Stewart Reid), and the Great Lakes Inst. Environmental Research ( Margaret Docker - lamprey genetics). 2) ODFW will, where appropriate, incorporate lampreys into their fish survey protocols in the Klamath Basin and will seek to collaborate with other researchers carrying out lamprey surveys in the Basin. 3) ODFW and the Miller Lake Lamprey Technical Management Team will promote the investigation of morphological and genetic information informative to resolving regional differences between the various populations of Miller Lake Lamprey. 11 Public Review Draft 4- 27- 05 Research, Monitoring and Evaluation Research Promote scientific studies of the Miller Lake Lamprey to aid in the conservation of the Monitoring Where appropriate, incorporate lampreys into fish survey protocols in the Klamath Basin and seek to collaborate with other researchers carrying out lamprey surveys in the Basin. Evaluation Periodically evaluate the status of Miller Lake lamprey and the success of the conservation plan management strategies. Research - Due to the paucity of available quantitative information on the distribution, life history, habitat requirements of either ammocoetes or adults, ODFW will promote scientific studies of the Miller Lake Lamprey to aid in the conservation of the species. Monitoring - ODFW, in collaboration with USFWS, has documented baseline distribution of the fish in Miller Creek with the lamprey barrier in place ( Gunckel and Reid 2004). Monitoring of the population will continue to evaluate upstream movement, distribution, abundance, and re- colonization of the lake through the cooperative effort of ODFW and the Miller Lake Lamprey Technical Management Team. The ODFW and the Technical Management Team, will meet and discuss progress after the barrier has been removed, and the lampreys have had unobstructed passage to Miller Lake for five years. Adaptive Management a) A Miller Lake Lamprey Technical Management Team shall be formed. b) The Miller Lake Lamprey Technical Management Team shall meet periodically to review the success of the management actions identified in the Miller Lake Lamprey Conservation Plan and identify modifications to management actions that are needed to achieve the desired status for Miller Lake lamprey. No immediate threats to the Miller Lake Lamprey are known to currently exist, except for the barrier in Miller Creek. The Miller Lake Lamprey Technical Management Team ( see under Strategies to Address Gaps) has been formed to promote investigation, management and conservation of the Miller Lake Lamprey. The team will meet periodically to evaluate current status and management strategies in light of new information. 12 Public Review Draft 4- 27- 05 Current management action is proposed for removal of the Miller Creek Barrier. The lamprey population in Miller Creek will continue to be monitored by ODFW following the 2004 baseline surveys. After five years the Miller Lake Lamprey Technical Management Team will evaluate the status of the Miller Creek population and the success of natural re- colonization of Miller Lake. If sufficient progress has not been made, then discussions regarding active re- introduction of lampreys to the lake will be initiated. Trigger for Plan Modification Substantial negative changes in the distribution or abundance of the Miller Lake lamprey, or the recognition of new threats to the species, shall prompt a review of the species management unit's status and all Miller Lake Lamprey Conservation Plan management strategies by the Miller Lake Lamprey Technical Management Team. Appropriate modifications to the Miller Lake Lamprey Conservation Plan intended to better achieve the desired status identified in the Plan shall be proposed by the Miller Lake Lamprey Technical Management Team. Reporting a) The Miller Lake Lamprey Technical Management Team shall periodically report on the status of Miller Lake lamprey and the effectiveness of the management strategies identified in the Miller lake Lamprey Conservation Plan. b) Annual Miller Lake Lamprey data collected and any reports on the status of Miller Lake Lamprey or evaluations of the Miller Lake Lamprey Conservation Plan shall be made available to the public. The staff of the ODFW's Klamath Watershed District and Native Fish Research Project will periodically report monitoring and research results through native fish conservation strategy stock status reviews. 13 Public Review Draft 4- 27- 05 Citations Bond, C.

The lamprey population was later recognized to be a distinct species, Lampetra minima ( Bond and Kan 1973). It was the smallest lamprey species in the world ( maturing at less than 4 in), and at that time was known only from Miller Lake, where it was extinct In 1992, a small lamprey caught in the Upper Williamson River was identified as a Miller Lake Lamprey, and subsequent investigations have identified six local populations of this lamprey in two small subdrainages of the Upper Klamath Basin. Management strategies to preserve this species include: conserving appropriate habitat conditions and availability within the natural range of the Miller Lake Lamprey, addressing potential impacts from stocking streams with hatchery fish, reducing entrainment, and establishing connectivity within and between local populations. A man- made barrier built in 1959 still exists on Miller Creek. Originally created to prevent the re- establishment of lamprey in Miller Lake after the chemical treatment, the barrier currently prevents natural dispersal of the Miller Creek population and re- colonization of both extensive habitat in upper Miller Creek and Miller Lake itself. Removal of the barrier, which is in disrepair but continues to exclude lamprey, is feasible and will eliminate the only man- made feature obstructing natural connectivity within the Miller Lake drainage, the species' type locality. This conservation plan is intended to provide guidance for management actions and conservation of the Miller Lake Lamprey. Introduction lhe Miller Lake Lamprey, Lampetra { Entosphenus) minima, is the worlds smallest predatory lamprey, reaching a size of only 3- 6", and is endemic to the Klamath Basin ( Bond and Kan 1973, Gill et al. 2003, Lorion et al. 2000). It is also one of the few species to have " recovered" from extinction. Miller Lake was chemically treated with toxaphene by the Oregon Game Commission on September 16,1958 to eliminate Tui Chub ( Siphateles bicolor) and a population of unidentified lamprey ( Gerlach 1958, Gerlach and Borovicka 1964). The lamprey in Miller Lake was later discovered to have been a unique species, apparently restricted in range to the Miller Lake drainage ( a small, disjunct tributary to the Upper Williamson River), and was scientifically described by Bond and Kan ( 1973) fifteen years subsequent to its presumed extirpation. Public Review Draft 4- 27- 05 Although there appear to be no immediate threats to the Miller Lake Lamprey ( Kostow 2002), the species is of considerable conservation concern due to: 1) its relatively limited range in two small sub drainages of the Klamath Basin, 2) its continued absence in the ecologically unique setting of Miller Lake ( type locality) and 3) its evolutionary distinctiveness as the smallest known predatory lamprey in the world, maturing at less than four inches. Life History Distribution - The Miller Lake Lamprey is currently known from only two small sub- drainages of the Upper Klamath Basin, the upper Williamson River and the upper Sycan River above Sycan Marsh ( Lorion et al. 2000). The upper Williamson River contains four known populations ( Miller Creek, Jack Creek, Klamath Marsh, and mainstem Williamson River above the marsh). Miller Creek, which drains Miller Lake, is within the upper Williamson Watershed, but it goes sub- surface in the pumice soils and does not reach the Klamath Marsh or Williamson River. Miller Lake has presumably been isolated from the rest of the drainage since the eruption of Mt. Mazama ( Crater Lake) over 6,000 years ago. Jack Creek, a small northern tributary to the upper Williamson River, is also generally disjunct from the mainstem Williamson River due to low, intermittent surface flows in its lower reaches. The Upper Sycan drainage ( a northern tributary of the Sprague River) contains two principal populations, Long Creek drainage and the upper Sycan River drainage above Sycan Marsh. Lamprey have been documented in Coyote Creek and Shake Creek above Sycan Marsh by Nature Conservancy. Lamprey in Shake Creek have not been identified to species. Geographic Variability - In general, individuals from the modern Williamson and Sycan sub-drainages are morphologically similar ( Lorion et al. 2000). However, there are indications of geographic differences between populations. The Sycan populations exhibit significantly higher variability in the number of bicuspid posterial teeth, and the Miller Creek population generally tend to be darker on their ventral surface. Specimens from the original Miller Lake population ( pre- 1958) had, on average, fewer anterial teeth. They also tended to have larger eyes and oral disks relative to total length when compared to modern populations; however, this appears to be due to their slightly smaller size. The available genetic information also indicates that there are geographic differences in the mitochondrial genome ( mtDNA) between Sycan ( Sprague) and Williamson lamprey populations, with one haplotype found only in the Upper Sycan and another limited to lamprey populations in the Sprague River drainage ( Lorion et al. 2000). Continued genetic work on the Klamath lamprey fauna, examining additional genes, indicates that the population of lamprey in Miller Creek may be genetically different than both the other upper Williamson and Sycan populations ( Docker pers. com. 2004). Habitat - Miller Lake Lampreys currently occupy relatively cool, clear streams ( Gunckel and Reid 2004, Kan and Bond 1981, Lorion et al. 2000, Reid pers. com. 2004). Adults are generally associated with structural cover, including loose rocks and woody debris. In lower Miller Creek, where rocky habitat is limited, adult lampreys were consistently found in woody debris jams and even under seat boards from an old outhouse that had fallen into the creek ( Reid pers. obs. 1998). Ammocoetes ( a larval stage lasting about 5 years) live in the substrate and are generally Public Review Draft 4- 27- 05 associated with depositional environments. In streams, ammocoetes are frequently found in silty backwater areas, low energy stream edges, and in pool eddies where leaf litter and other organics ( including adult lamprey carcasses) tend to accumulate. At night ammocoetes may move into the water column to disperse downstream or into more favorable habitat. In Miller Lake ammocoetes were found in organic detritus all along the shoreline but rarely in the extremely cold tributaries flowing into the lake ( Kan and Bond 1981). Recent extensive collections of Pacific Lamprey ammocoetes along the coast indicate that ammocoetes do not occupy otherwise apparently suitable sediments if the upper layer is poorly oxygenated ( Reid and Goodman pers. obs. 2004). Reproduction - Miller Lake Lampreys spawn in shallow redds in clean gravels and sand, which are moved out of the redd by lamprey sucking onto small rocks and actively moving them out of the way ( Markle pers. com. 2004, Reid pers. com. 2004). In streams, redds are generally made in shallow water, often at the tail of a pool or run, and are roughly 10 cm in diameter and a few centimeters deep. In Miller Lake, lampreys were observed spawning in water as deep as 20 feet ( Cochrun 1951b, Kan and Bond 1981). Males attach to the female's head and wrap around her body, aligning genitals and allowing fertilization of the eggs as they emerge. Eggs are heavier than water and are mixed into the bottom of the redd by spawning actions. Kan and Bond ( 1981) found that female lampreys from Miller Lake contained an average of about 600 eggs. Time to hatching is not known, but is probably on the order of a few weeks. Larvae ( ammocoetes) emerge at about 8 mm and move into fine sediments. Adults die after spawning. Feeding - Miller Lake Lampreys feed on fish only as adults. Ammocoetes have no eyes or teeth and are purely filter feeders, burrowing in the sediment and feeding on suspended microorganisms and algae. The ammocoete phase lasts about five years, during which time the ammocoetes grow to around 150 mm. After transformation, adults enter a predatory phase before spawning that generally lasts for less than a year ( from transformation in the summer/ fall to spawning in summer of the following year). Adults feed primarily on flesh that is gouged and rasped out of a small wound (<= 11 mm) under the sucking disk ( Cochran 1994, Kan and Bond 1981). Adults apparently show little selectivity for prey. The adult lampreys in Miller Lake historically fed on both tui chubs and available salmonids ( rainbow, brook and juvenile brown trout) in Miller Lake ( Kan and Bond 1981). They also scavenged dead tui chubs and trout, as well as cannibalizing other lampreys. In Miller Creek, most recent observations found occasional lamprey wounds on brook trout, which were the most abundant species in the creek, but it is probable that lampreys also feed on both rainbows and young brown trout in the creek ( S. Reid pers. obs. 1998). In Jack Creek lampreys feed on speckled dace, the only other fish present in the stream, and in the Upper Sycan they feed on both trout and dace. Unlike other predatory lampreys, but similar to non- feeding brook lampreys, adult Miller Lake Lampreys loose body length and mass between the time they transform and actual spawning, indicating that energetic needs and gonadal development are not compensated for by the amount of food they consume ( Hubbs 1971, Kan and Bond 1981, Lorion et al. 2000). Lamprey / Trout Interaction - Although there have been no direct studies of the ecological interaction between lampreys and trout in the Klamath Basin, it is notable that healthy trout and lamprey populations coexist throughout the basin. Lampreys certainly prey on trout, and both adult lampreys and ammocoetes may represent a significant food resource to piscivorous adult Public Review Draft 4- 27- 05 trout. Native redband trout co- exist with much larger predatory lampreys (" Klamath Lake Lamprey", Lampetra { Entosphenus) sp., and Klamath River Lamprey, L. ( E.) similis) in Upper Klamath Lake. A large percentage of the trophy redband trout in Upper Klamath Lake, as well as both redband and brown trout in the Wood and Williamson Rivers, exhibit recent or healed lamprey scars. In smaller streams where Miller Lake Lampreys ( length 3- 6 in) co- exist with native and introduced trout ( redband, bull, brook and brown trout), there appears to be little impact to adult trout, and local fishermen are rarely even aware of the presence of the lamprey ( S. Reid, pers. comm. 2004, R. Smith, pers. comm. 2004). Surveys by USFWS and USFS in 1998- 1999 found that very few of the trout in Miller Creek, the Williamson or upper Sycan Rivers had scars, and during extensive snorkeling surveys, only a few trout were actually observed with lampreys attached ( S. Reid USFWS pers. com., 2004). Historical reports from Miller Lake prior to the extirpation of lampreys indicate that tui chubs were the principal prey, and dead tui chubs were often reported ( Cochrun 1951a, b, Gerlach 1958, Kan 1975, Kan and Bond 1981). Some cannibalism on other lampreys, as well as scavenging of dead fish carcasses, was also observed ( Kan and Bond 1981). Specific mortality of adult trout was not reported, although large trout were noted to have collections of scars and some mortality of fingerlings was observed. Recent observations of occasional fingerling trout mortality and much more frequent lethal predation on speckled dace (< 10 cm TL) in the Sycan River and Jack Creek, as well as the observation of apparently healthy adult trout with healed wounds, suggests that lethal predation on trout is generally limited to fingerlings ( Markle pers. com. 2004, Reid pers. com. 2004, Smith pers. com. 2004). It is not believed that predation on Miller Lake lamprey by piscivorous adult trout has been a threat to the sustainability of lamprey populations. These populations have co- evolved with native trout and appear to be productive enough to withstand some level of predation. The Jack Creek population is an exception. Jack Creek is believed to only support populations of Miller Lake lamprey and speckled dace. Since this lamprey population evolved absent predation from trout, there is a concern that an introduction of piscivorous adult trout could upset the ecological balance in Jack Creek and present a threat to both the lamprey and dace populations. For this reason, stocking of hatchery fish is prohibited by rule in Jack Creek or other streams containing Miller Lake lamprey. Miller Lake Fisheries - Miller Lake currently supports a recreational trout fishery of entirely introduced species. Miller Lake's one notable native species, the Miller Lake Lamprey, was thought extinct when the Oregon Department of Fish and Wildlife Commission approved the current Klamath Basin Fish Management Plan ( ODFW 1997). Today, Miller Lake provides a popular " catchable" and fingerling rainbow trout program, a trophy brown trout fishery, and an under- utilized kokanee population of small- sized individuals ( Smith pers. com. 2004). Due to the role of Miller Lake as a recreational fishery and concerns over the potential impact of lampreys on introduced trout populations in the lake, the history and status of Miller Lake fisheries are summarized below by species. Rainbow trout fingerlings ( 2- 4 inches) were planted in Miller Lake until 1948, when stocking was discontinued due to poor returns. At that time, the poor rainbow fishery was believed to have been due to lamprey predation and competition with resident tui chubs ( Cochrun 1950, Public Review Draft 4- 27- 05 1951a). However, based on the reported poor performance of stocked fingerling rainbows post-treatment ( see below), without either lampreys or tui chubs, it appears that local habitat conditions, and not trophic competition with tui chub or parasitism by lamprey, were driving the poor rainbow population dynamics. Recent observations by ODFW biologists have indicated that while the rainbow trout in Miller Lake are surviving, growing and being harvested by anglers, survival and growth have been, at best, marginal ( Smith pers. com. 2004). Trapnet samples in Miller Lake have been very inefficient at capturing older age class rainbow trout so the average size of sampled trout is not representative of the fish that are available for angler harvest. While trapnet sets typically made in the fall are not particularly good indicators of the rainbow population in Miller Lake, Trapnet sampling of rainbow trout documented an average length of approximately 8 inches in 1988 and approximately 4 inches in 1997. The release of catchable- sized rainbow trout into Miller Lake was initiated in 2001 to supplement the ongoing fingerling stocking program. Brown trout were first introduced into Miller Lake in 1981 and have been stocked annually since. Although small numbers may have been present prior to treatment. Survival and growth of brown trout has been excellent ( Smith pers. com. 2004). Brown trout averaged approximately 17 inches in length in 1998 and approximately 16 inches in 2001. Larger fish captured in trap net sets exceed 10 pounds. Miller Lake was identified by sport- fishing author Denny Rickards as one of the top ten brown trout producing lakes in the western United States. Lampreys themselves, as well as their impaired prey, might in turn serve as additional prey for the large, highly piscivorous brown trout. Stocks of kokanee were introduced to Miller Lake from several states between 1964 and 1971 ( all post- treatment). Kokanee have been very successful reproducing and stocking has not been necessary since 1971. The average size of maturing adults have remained relatively small. Miller Lake is an oligotrophic lake with very low productivity ( Johnson et al. 1985). The length of maturing female kokanee ranged between 7.5- 10 inches between 1965 tol972, and the average size of kokanee females in 2001 was approximately 8 inches. Based on the relatively small length of maturing kokanee females, it appears that environmental conditions or interspecific competition with other trout are driving the kokanee population dynamics. Brook trout were stocked in Miller Lake from the 1930' s until 1948. Brook trout were present in Miller Creek and apparently survived in tributaries during the 1958 treatment, since seven brook trout ( 6- 14 in) were gill- netted from the lake in 1964, prior to introduction of 85,000 kokanee and 150,000 rainbow fingerlings. No brook trout are currently stocked into the lake or tributaries of the lake. A healthy self- sustaining population of brook trout is currently present in Miller Creek, below the lamprey barrier, where they have apparently coexisted with lampreys since both recovered from the 1958 treatment. Tui chubs were present in Miller Lake prior to the 1958 treatment. It is not known whether tui chub were a native or introduced population. However, based on the elevation and atypical tui chub habitat in the lake, it is believed to have been an un- authorized introduction, most probably as a baitfish. Trophic competition between tui chub and rainbow trout has been consistently demonstrated in several Oregon lakes, including Diamond Lake in Douglas County. Tui chub or " roach" problems in Miller Lake were identified by Ken Cochrun ( Fisheries Agent, Oregon State Public Review Draft 4- 27- 05 game Comm.) in his 1950 and 1951 annual reports ( Cochrun 1950, 1951a). However, Mr. Cochrun felt that the " large population" of tui chub would be relatively easy to control compared to the lamprey and hence the need for the radical chemical treatment with toxaphene, which would eliminate both species, rather than rotenone, which would have limited effect on the lamprey ammocoetes in the substrate. In the 1950' s, as is still the case, considerable amount of time was expended by fishery districts controlling tui chub (" roach"), as noted in Mr. Cochrun's annual reports. Tui chubs were never restocked after the treatment and are no longer present in the Miller Lake drainage. One of the goals of this conservation plan for the Miller Lake Lamprey is to re- establish a lamprey population in Miller Lake itself. Historical reports from Miller Lake prior to the extirpation of lampreys nowhere mention specific mortality of adult trout, even when lamprey were abundant, although large trout were noted to have collections of scars ( see above - Lamprey/ Trout Interaction). Based on historical accounts and recent observations from the Upper Sycan drainages, mortality when observed has been on small fish (< 10cm TL). Observations from Miller Lake in the past and recent observations of trophy redband trout fisheries in Upper Klamath Lake indicate that little to no effect is experienced by the fish based on the occurrence of healed lamprey scars. Self- sustaining populations of brown and brook trout ( unstocked) currently coexist with lampreys in Miller Creek below the lamprey barrier. Were lamprey to become reestablished in Miller Lake, they would probably feed primarily on juvenile kokanee, which are abundant in the lake. Although lamprey predation on adult trout may result in some stress and condition loss, the principal effect on adult kokanee and trout fisheries in Miller Lake is likely to be aesthetic, with small round wounds (< l/ 2 in), or scars, on the side of fish. Future Recreational Fish Management The recreational trout and kokanee salmon fisheries in Miller Lake are an extremely valuable fish resource to local community and anglers. All efforts will be made by the Oregon Department of Fish and Wildlife to continue to offer angling recreation at current harvestable levels. In the unlikely event that the re- establishment of the Miller Lake lamprey adversely impacts the trout and kokanee population abundance, then additional fish stocking or other compatible management actions will be initiated as necessary to meet recreational fishery management objectives. Conservation Plan Note: Underlined, bold text in italics represents those portions of the conservation plan that are proposed to be adopted into Oregon Administrative Rule by the Oregon Fish and Wildlife Commission. Purpose This conservation plan is intended to provide guidance for management actions and conservation of the Miller Lake lamprey, Lampetra ( Entosphenus) minima. This is the first step in securing populations that currently exist in the Klamath Basin and in Public Review Draft 4- 27- 05 determining their status, abundance, distribution, and life history needs. As new information on the lamprey becomes available it is expected that this document will be modified and updated to reflect the current state of our knowledge. Species Management Unit and Population Description The Miller Lake Lamprey species management unit is comprised of six documented populations and one uncertain population. They are: • Mainstem Upper Williamson River above Klamath Marsh • Miller Creek • Jack Creek • Sycan River above Sycan Marsh • Long Creek • Coyote Creek • Shake Creek ( lamprey present have not been identified to species) Desired Status The desired status of the Miller Lake lamprey is for the species to be distributed widely throughout its historic range, with populations robust enough to withstand stochastic environmental events, and with both the populations and their habitat secure from anthropogenic threats. Current Status The Miller Lake Lamprey is endemic to the Klamath Basin and was recently re- described ( Lorion et al 2000). It is currently known from two sub- drainages. The Williamson River sub- drainage includes populations in Miller Creek, Jack Creek, Klamath Marsh and the mainstem upper Williamson River. In the Sycan sub- drainage the lamprey exists in Long Creek and in the upper Sycan River above the Sycan Marsh. Information regarding the abundance and population structure of Miller Lake lamprey in these systems is not available, and only anecdotal information is available for the life history or habitat requirements of the species. For detailed information on the current information available for the species see Life History section. No immediate threats to the Miller Lake Lamprey are known to currently exist, except for the barrier to connectivity between Miller Creek and Miller Lake. Public Review Draft 4- 27- 05 Management Strategies The short- and long- term management strategies for the Miller Lake Lamprey species management unit are: Short- term Strategy a) Re- establish connectivity to Miller Lake. Long- term Strategies b) Ensure appropriate habitat conditions and availability within the natural range of Miller Lake lamprey. c) Reduce entrainment or the potential for entrainment of adult and larval lampreys into water diversions. d) Reduce stranding or the potential for stranding of larval lampreys in dewatered segments of streams below water diversions. e) Maintain unobstructed opportunities, within and among populations for genetic exchange, natural dispersal or migration activities, and re- colonization of unoccupied portions of historical habitat. f) No hatchery fish shall be stocked in streams that support Miller Lake lamprey. Management strategies are those general conditions relevant to the conservation of the species that are considered essential to ensure its long- term survival within its natural range. Although there are many aspects of a species life- history and management that may play a role in the species' biology, the management strategies include those aspects that are currently considered to be both essential for its long- term survival and that are potentially at risk. Conservation Actions Conservation actions are those specific activities or projects that have been identified as appropriate for the realization of the above conservation goals. General - Due to the general lack of information about the life- history, habitat requirements, and distribution of the Miller Lake Lamprey, any studies which increase our understanding of the species will contribute to future conservation planning and should be supported. Habitat - At this time, the general habitat requirements of the Miller Lake Lamprey populations in the upper Williamson and upper Sycan drainages appear to be similar to those of the native trout populations, and habitat restoration or enhancement projects that benefit the trout populations should be beneficial to the lamprey as well. However, there may be specific differences between these species that should be considered in future projects as our understanding of the lamprey's life- history increases. Public Review Draft 4- 27- 05 Entrainment - At this time there has been no evaluation of potential entrainment risks to the Miller Lake Lamprey. Unscreened or improperly screened irrigation diversions currently exist on the upper Sycan and upper Williamson River systems. Private irrigator participation into the screening program should continue to be encouraged and supported. Stranding - At this time there has been no evaluation of potential stranding risks to the Miller Lake Lamprey. Current water diversions reduce the stream flow in segments of the streams directly below the diversion point. Minimum stream flows or gradual ramping strategies should be encouraged where practicable. Connectivity - The Miller Lake Lamprey is not known to carry out extensive spawning migrations. However, due the tendency for ammocoetes to drift downstream during the multi- year larval stage, it is essential that local populations have free upstream passage opportunities during the period when adults are residing in the stream. The swimming characteristics and passage capabilities of trout ( for whom many fish ladders are designed) and lamprey are very different. Lamprey- friendly ladders or passage corridors should be encouraged in the design phase of new projects, and occupied lamprey streams should be evaluated for the presence of older fish ladders, as well as other artificial barriers. Re- establishment of the Miller Lake population - Miller Lake itself, the type locality for the species, remains the only known historical habitat from which the Miller Lake Lamprey is known to have been extirpated. It also represents both an ecologically unique habitat and a crucial component in the evolutionary legacy of the species. Following the extirpation of lampreys from Miller Lake in 1958, a lamprey barrier was constructed in Miller Creek to prevent recolonization of the lake from Miller Creek. The barrier remains in place today. Removal of this barrier should have a high priority in order to meet the conservation goals for the Miller Lake Lamprey and is discussed in more detail below. The barrier was constructed by the State of Oregon Game Commission in 1959 at the upstream extent of a short, high- gradient cascade in Miller Creek approximately 54 mile downstream from the outlet of Miller Lake and forest road 9772. It consists of a low stonework dam ( about 2 ft high) constructed of mortared native rocks, with a metal plate and lip bolted on top. The configuration is very effective as a man- made barrier to fish passage. However, the current condition of the concrete and rock structure is substantially deteriorated. A recent examination by ODFW, USFWS and USFS personnel indicates that the structure would be relatively easy to remove using hand tools without adverse instream impacts ( evaluated by R. Smith et al., September 2003). Recent baseline surveys ( August 2004) of lamprey ammocoetes in the Miller drainage indicate that they are apparently limited to less than two miles of low- gradient stream in lower Miller Creek ( Gunckel and Reid 2004). Allowing lampreys to re- establish a population above the cascade in Miller Creek and Miller Lake will aid in creating an additional buffer against stochastic events that could otherwise eradicate this geographically limited population. Additional surveys should be scheduled on a five- 10 Public Review Draft 4- 27- 05 year basis to evaluate status of the population and the success of re- colonization efforts. Removal of the barrier should allow natural expansion of the population and recolonization of the lake from the Miller Creek population, which survived the original extirpation. Information Gaps 1) Life history - very little quantitative information is available on the life history and habitat requirements of either ammocoetes or adults with which to guide management decisions. 2) Distribution - current understanding of distribution is based on surveys in the 1990' s that primarily focused on the Williamson and Sprague River drainages. Other potential areas in the Klamath Basin outside these drainages have not been properly surveyed. 3) No specific population or fine- scale distributional surveys have been undertaken for any populations outside of the Miller Lake drainage. 4) Preliminary morphological and genetic information suggests that there are regional differences between the various populations of Miller Lake Lamprey in the Klamath Basin. However, the available information is not yet sufficient for making management decisions relative to population independence or uniqueness. Strategies to Address Gaps 1) A Miller Lake Lamprey Technical Management Team has been formed to promote investigation, management and conservation of the Miller Lake Lamprey. This team currently consists of biologists from ODFW ( Roger Smith and Stephanie Gunckel), Oregon State University ( Douglas Markle), the Western Lamprey Project ( Stewart Reid), and the Great Lakes Inst. Environmental Research ( Margaret Docker - lamprey genetics). 2) ODFW will, where appropriate, incorporate lampreys into their fish survey protocols in the Klamath Basin and will seek to collaborate with other researchers carrying out lamprey surveys in the Basin. 3) ODFW and the Miller Lake Lamprey Technical Management Team will promote the investigation of morphological and genetic information informative to resolving regional differences between the various populations of Miller Lake Lamprey. 11 Public Review Draft 4- 27- 05 Research, Monitoring and Evaluation Research Promote scientific studies of the Miller Lake Lamprey to aid in the conservation of the Monitoring Where appropriate, incorporate lampreys into fish survey protocols in the Klamath Basin and seek to collaborate with other researchers carrying out lamprey surveys in the Basin. Evaluation Periodically evaluate the status of Miller Lake lamprey and the success of the conservation plan management strategies. Research - Due to the paucity of available quantitative information on the distribution, life history, habitat requirements of either ammocoetes or adults, ODFW will promote scientific studies of the Miller Lake Lamprey to aid in the conservation of the species. Monitoring - ODFW, in collaboration with USFWS, has documented baseline distribution of the fish in Miller Creek with the lamprey barrier in place ( Gunckel and Reid 2004). Monitoring of the population will continue to evaluate upstream movement, distribution, abundance, and re- colonization of the lake through the cooperative effort of ODFW and the Miller Lake Lamprey Technical Management Team. The ODFW and the Technical Management Team, will meet and discuss progress after the barrier has been removed, and the lampreys have had unobstructed passage to Miller Lake for five years. Adaptive Management a) A Miller Lake Lamprey Technical Management Team shall be formed. b) The Miller Lake Lamprey Technical Management Team shall meet periodically to review the success of the management actions identified in the Miller Lake Lamprey Conservation Plan and identify modifications to management actions that are needed to achieve the desired status for Miller Lake lamprey. No immediate threats to the Miller Lake Lamprey are known to currently exist, except for the barrier in Miller Creek. The Miller Lake Lamprey Technical Management Team ( see under Strategies to Address Gaps) has been formed to promote investigation, management and conservation of the Miller Lake Lamprey. The team will meet periodically to evaluate current status and management strategies in light of new information. 12 Public Review Draft 4- 27- 05 Current management action is proposed for removal of the Miller Creek Barrier. The lamprey population in Miller Creek will continue to be monitored by ODFW following the 2004 baseline surveys. After five years the Miller Lake Lamprey Technical Management Team will evaluate the status of the Miller Creek population and the success of natural re- colonization of Miller Lake. If sufficient progress has not been made, then discussions regarding active re- introduction of lampreys to the lake will be initiated. Trigger for Plan Modification Substantial negative changes in the distribution or abundance of the Miller Lake lamprey, or the recognition of new threats to the species, shall prompt a review of the species management unit's status and all Miller Lake Lamprey Conservation Plan management strategies by the Miller Lake Lamprey Technical Management Team. Appropriate modifications to the Miller Lake Lamprey Conservation Plan intended to better achieve the desired status identified in the Plan shall be proposed by the Miller Lake Lamprey Technical Management Team. Reporting a) The Miller Lake Lamprey Technical Management Team shall periodically report on the status of Miller Lake lamprey and the effectiveness of the management strategies identified in the Miller lake Lamprey Conservation Plan. b) Annual Miller Lake Lamprey data collected and any reports on the status of Miller Lake Lamprey or evaluations of the Miller Lake Lamprey Conservation Plan shall be made available to the public. The staff of the ODFW's Klamath Watershed District and Native Fish Research Project will periodically report monitoring and research results through native fish conservation strategy stock status reviews. 13 Public Review Draft 4- 27- 05 Citations Bond, C.

Committee on Resources Year: 2005, 2007 I. Executive Summary There is increasing recognition from most quarters that the Endangered Species Act (ESA) needs to be improved. Exactly what those improvements should be is less uniform. This report examines the implementation of selected aspects of the endangered species program relying predominately on information provided by the primary implementing agencies, the United States Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) and offers some recommendations for possible improvements to the program. Debate over the ESA has traditionally been highly polarized. For example, compensating landowners for takings or reductions in property value has been opposed by some who argue updating the law to address this is not necessary. While consensus on other issues such as the need for increasing conservation incentives and the role states play in endangered species conservation has begun to emerge, one of the most debated aspects of ESA implementation continues to be whether the ESA is effectively conserving endangered and threatened species. While there have been significant strides in conserving individual species such as the whooping crane, red-cockaded woodpecker and gray wolf, few species have been delisted (removed from the endangered list) or downlisted (changed in status from endangered to threatened) because of successful ESA conservation efforts. Some argue that the number of recovered species is an unfair measure, asserting that the three decades the ESA has been in existence is an insufficient amount of time for the lengthy process of species recovery and point to listed species that have not gone extinct as evidence the ESA 'saves' species. From the opposing perspective, while recovery to the point of delisting may require a substantial amount of time for many species, after three decades more progress should be demonstrable through species that have recovered and been delisted. Even if a species has increased in numbers or distribution or the threats facing the species have been reduced, if it has not been delisted on the basis of recovery, the ESA's prohibitions and regulations remain applicable and the ESA should not be a 'one way street.' Of 40 total species removed from the list, 10 domestic species were delisted because of "recovery". Of 33 reclassified species, 10 domestic downlistings (a change from endangered to threatened status) reflected a reduced threat assessment which also allowed more flexibility in management. The FWS's most recent report to Congress (Fiscal years 2001-2002) shows that 77 percent of listed species fall in the 0 to 25 percent recovery achieved bracket and 2 percent fall in the 76 to 100 percent recovery achieved bracket. 39 percent of the FWS managed species are of uncertain status. Of those with an assessed trend, at one end of the spectrum are 3 percent possibly extinct, 1 percent occurring only in captivity and 21 percent declining and at the other end are 30 percent stable and 6 percent improving. These assessments however are subjective. Additionally, the assessment that a species is improving or stable may reflect, for example, a reduction in perceived threats or corrections to inaccurate threat assessments that stemmed from erroneous data rather than actual changes in species' trends that are demonstrated by improved numbers, distribution or other such measurements. Consequently, a meaningful assessment of conservation trends under the ESA using these data is not possible. The data used to list a number of species has been subsequently determined to be erroneous and species that likely do not merit classification as endangered or threatened remain listed. This can consume resources that could be directed to species that do merit listing. The assignment of recovery priorities appears highly skewed and the recovery priority for some species seems questionable. A meaningful distinction between endangered status and threatened status has been blurred as has been the framework for the mechanism of critical habitat. Expenditure reporting has improved but presents an incomplete picture of financial resources dedicated to endangered species. Workloads for litigation regarding activities such as consultation and listing under the ESA's complex structure compete for resources that could otherwise be directed at recovery efforts. The demands associated with ESA Section 4 determinations in combination with the pace of species listings and delistings, the number of possible future additions to the list and the economic impact of listings likely indicate that the current program is not sustainable.

G Year: 2001, 2007, 2005 ABSTRACT A water quality study was performed in the mainstem Klamath River from Keno, Oregon to Seiad Valley, California during 1996 through 1998. Four sites within the study area were continuously monitored using multiparameter recorders. Water quality sampling was also performed at these four locations in 1996 and 1997. Additional water quality sampling sites were added in 1998 for a total of 8 locations between Keno and Seiad. Temperature ranged from near zero ?C to >25 ?C with cooler temperatures in early spring and fall, and maximum temperatures occurring in July and August of each year. Dissolved oxygen concentration ranged from near zero mg/L to >13 mg/L with highest DO occurring in early spring and fall and lowest DO occurring in mid-summer. Air temperature was generally highly correlated with water temperature with r values ranging from 0.8 to 0.9 during the study period from 1996-1998. Water temperature in the study area exceeded chronic (>16?C) and acute (>22?C) criteria for salmonids during the summer months. Although chronic DO (<7 mg/L) criteria were exceeded throughout most of the study area during the summer, in the free-flowing river below Iron Gate Dam the acute DO (<5.5 mg/L) criteria were not exceeded. Nonpoint source pollution in the form of agricultural return flows, industrial, or sewage effluent entering the stream may have resulted in higher ammonia and total organic nitrogen concentrations at the upstream locations in the Klamath River study area (Keno and J.C. Boyle Powerplant). Nitrification of ammonia and organic nitrogen seemed to result in higher concentrations of nitrate in the downstream Klamath River (Iron Gate Dam). Total phosphorus concentration stayed relatively stable through the reservoirs in the study area, but decreased in the downstream direction between Iron Gate Dam and Seiad. Ortho-phosphorus concentrations increased longitudinally through the reservoirs, then decreased in the downstream direction between Iron Gate Dam and Seiad. An increase in ortho-phosphorus concentration can indicate internal cycling occurring in the reservoirs as well as photosynthesis. On an annual basis total phosphorus loading increased longitudinally from up- to downstream between Keno and Seiad. The increase was statistically significant (p = .03) indicating that the reservoirs in series in the Klamath River study area do not function as a nutrient sink. However, during the summer there was no statistically significant difference in total P loading when Keno, Iron Gate and Seiad locations were compared, therefore, the reservoirs may act as a nutrient sink seasonally. The Klamath River study locations were generally nitrogen limited, although at Keno, a regular change from N limitation to P limitation occurred during the fall of all three years of the study. When the Klamath River annual nutrient loading values are compared to other rivers in the vicinity, the Carson, Truckee, and Long Tom Rivers also appear to be nutrient enriched. The Carson and South Yamhill Rivers seem to be N limited systems and the Wood, Long Tom, Snake and Truckee Rivers seem to be P limited systems. Implementing management strategies for reservoir operations to improve water quality and reduce nutrient concentration or loading in the Klamath River study area to benefit anadromous fisheries may be difficult and expensive. However, improving the thermal regime in spring to benefit YOY salmonids may be possible as is short-term relief in fate summer for over-summering species. Decreases in nutrient concentration or loading accomplished through best management practices in the water shed may allow general protection of water resources in the Klamath Basin for future needs.

Nazzaro Author: Nazzaro, Robin M Year: 2005, 2007 Summary In summary, we found that federal agencies have taken steps to improve collaboration as a way to reduce conflicts that often occur between species protections and other resource uses, but that more could be done to promote routine use of collaboration and clarify agencies' responsibilities under the Endangered Species Act. In September 2003, we reported on efforts taken by the Department of Defense (DOD) to coordinate with other federal land managers in order to reduce the impact of species protections on military activities. We found several cases where such efforts were successful. For example, at the Barry M. Goldwater range in Arizona, Air Force officials worked with officials at FWS and the National Park Service to enhance food sources for the endangered Sonoran pronghorn in locations away from military training areas. As a result, the Air Force was able to minimize the impact of restrictions on training missions due to the presence of the pronghorn. However, such cases were few and far between because, among other things, there were no procedures or centralized information sources for facilitating such collaboration. In March 2004, we reported on collaboration that takes place pursuant to section 7(a)(2) of the act?referred to as the consultation process?in the Pacific Northwest. In this area, large numbers of protected species and vast amounts of federal land conspire to make balancing species protection and resource use a contentious endeavor. We found that steps the Services and other federal agencies had taken made the consultation process run smoother and contributed to improved interagency relationships. However, some problems have persisted. For example, some agencies disagree with the Services about when consultation is necessary and how much analysis is required to determine potential impacts on protected species. In each of these reports, we made recommendations intended to further improve collaboration among federal agencies with regard to balancing species protections and other resource uses, and?in the March 2004 report?to resolve disagreements about the consultations process. DOD and FWS have begun discussing an implementation strategy to improve collaboration regarding species protection on military and other federal lands and development of a training program. With regard to the consultation process, while FWS and NMFS have continued to take steps to expand their collaboration processes, the agencies did not believe that disagreements about the consultation process require additional steps. They believe that current training and guidance is sufficient to address questions about the process. With regard to the use of science, we have found that FWS generally used the best available information in key Endangered Species Act decisions, although the agency was not always integrating new research into ongoing species management decisions. In addition, we identified concerns with the adequacy of the information available to make critical habitat decisions. In December 2002, we reported on many aspects of the decision making for species protections regarding the Mojave Desert tortoise. We found that the decision to list the tortoise as threatened, its critical habitat designation, and the recommended steps in the species' recovery plan, were based on the best available information. However, despite over $100 million in expenditures on recovery actions and research over the past 25 years, it is still unclear what the status of the tortoise is and what effect, if any, recovery actions are having on the species because research has not been coordinated in a way to provide essential management information. Such information is critically important as some of the protective actions, such as restrictions on grazing and off road vehicle use, are vigorously opposed by interest groups who question whether they are necessary for the tortoise's recovery. Accordingly, we recommended that FWS better link land management decisions with research results to ensure that conservation actions and land use restrictions actually benefit the tortoise. In response, FWS recently established a new office with a tortoise recovery coordinator and plans to create an advisory committee to ensure that monitoring and recovery actions are fed back into management decisions. In August 2003, we found that, similar to the decision making regarding the tortoise, FWS decisions about listing species for protection under the act were generally based on the best available information. However, while most critical habitat designations also appeared to be based on the best available information, there were concerns about the adequacy of the information available at the time these decisions are made. Specifically, critical habitat decisions require detailed information of a species' life history and habitat needs and the economic impacts of such decisions?information that is often not available and that FWS is unable to gather before it is obligated under the act to make the decision. As a result, we recommended that the Secretary of the Interior clarify how and when critical habitat should be designated and identify if any policy, regulatory, or legislative changes are required to enable the department to make better informed designations. FWS has not responded to our recommendation.

  	Citation × Citation Citation Abstract Copy Title: Lower Klamath River instream flow study : scoping evaluation for the Yurok Indian Reservation Author: Anglin, Donald R Year: 1994, 2007, 2006 ABSTRACT The U.S. Fish and Wildlife Service, Lower Columbia River Fishery Resource Office was funded by Bureau of Indian Affairs to conduct an instream flow assessment for the lower Klamath River within the Yurok Indian Reservation in northern California using the Instream Flow Incremental Methodology (IFIM). Specific study tasks consisted of developing an explicit statement of purpose, definition of the study area and target species, assembly and evaluation of hydrologic, water quality, and physical data as well as biological and fish habitat information. A reconnaissance survey of the proposed study area was also conducted. The purpose for conducting the proposed flow study was the Yurok Tribe's desire to protect the Klamath basin water supply for the production of anadromous fish. The ultimate goal was to protect, restore, and enhance the anadromous fishery resources on the Reservation and in the basin as a whole. The study area was defined as the lower Klamath River and tributaries from the confluence with the Trinity River downstream to the area of tidal influence. Although the mainstem Klamath only was proposed for flow studies, the tributaries were included in the study area as a result of their hydrologic and biological relevance. Target species were identified as chinook salmon {Oncorhynchus tshawytscha), coho salmon (0. kisutch), steelhead trout (0. mykiss) , green sturgeon {Acipenser medirostris) , eulachon (Thaleichthys pacificus) , and Pacific lamprey (Lampetra tridentata) . Assembly and evaluation of relevant information was accomplished from results of a public scoping meeting and the review of a large volume of both published and file reports as well as numerous personal communications. Hydrology of the lower Klamath River is affected by U.S. Bureau of Reclamation projects in both the upper Klamath and upper Trinity subbasins. Several hydroelectric projects in the upper Klamath subbasin affect flow patterns, and agricultural activities in the upper Klamath subbasin and tributaries and the Central Valley Project in the upper Trinity subbasin have reduced water yield from the basin. Water quality concerns were identified as elevated water temperatures and nutrient levels resulting from land use activities throughout the basin. Hydrologic and water quality impacts are partially mitigated in the lower Klamath by tributary inflow throughout the basin. The physical environment in the basin has been altered by land use practices and several major flood events. Alterations include loss of riparian vegetation and stream channel stability, loss of soil moisture storage capacity and infiltration potential, debris slides and logjams resulting in migration barriers, reduced supply of large woody debris for recruitment into the stream channel, and sedimentation of spawning and rearing habitat. Fish habitat in most lower Klamath tributaries has been surveyed and deficiencies as well as good quality habitat have been described. Significant production potential exists in most tributaries, however much restoration work needs to be completed to realize the potential. Habitat characteristics for the mainstem Klamath have not been described. Life history and production data are presented for target species and a brief review of sources for suitability criteria is presented. Harvest management and escapement for naturally spawning fall chinook salmon were reviewed from 1978 through 1993. Escapement has varied over the years but a general downward trend in naturally spawning fall chinook can be observed, particularly in recent years. Escapement goals for the Klamath basin varied from 115,000 in 1978 to an "emergency" floor of 27,000 in 1992. Actual escapement of naturally spawning adult fall chinook varied from a high of 113,000 in 1986 to a low of 11,600 in 1991. Escapement in 1978 totalled 58,500 and preliminary estimates of escapement in 1993 were 21,000 naturally spawning adults. Factors affecting production and subsequent stock size and escapement included variable ocean survival, degraded freshwater habitat conditions, the recent six-year drought, releases of large numbers of hatchery juveniles, and harvest management methodologies that have failed to adequately match harvest to predicted stock size. Differential harvest rates for Klamath and Trinity subbasin fall chinook have also complicated attempts to structure the harvest. Field reconnaisance surveys were conducted in spring and summer 1993 for the proposed mainstem Klamath study area. Two distinct river segments were identified based on macrohabitat characteristics. Microhabitat was classified within each river segment and mapped on USGS quadrangle maps. Cross section identification was postponed pending the decision to move forward with the flow study. Following the scoping tasks described above, conclusions and recommendations were developed. No information was reviewed that indicated the need for an instream flow study in the lower Klamath River. The two basic problems affecting anadromous fish production are degraded freshwater habitat and chronic underescapement. Coordination and planning for instream flow studies on a basin-wide scale was recommended. Biological data gaps were identified which need to be addressed before an instream flow study can be completed for the lower Klamath. Suitability criteria for habitat analysis also need to be identified. Habitat restoration and protection and proper management of anadromous fishery resources were identified as the highest priorities to begin restoration of anadromous stocks. Specific recommendations for habitat restoration included watershed and riparian zone restoration, barrier removal, instream habitat inventory, restoration, and monitoring, estuary studies, and description of streamflow characteristics for lower Klamath tributaries. Recommended fishery resource studies included collection of basic life history data, monitoring for adult escapement and juvenile production, description of estuary usage, effects of hatchery programs on both adult and juvenile wild fish, evaluation of the accelerated stocking program, and refinement of harvest management methodologies to achieve appropriate escapement of naturally spawning stocks into all subbasins. Title: Lower Klamath River instream flow study : scoping evaluation for the Yurok Indian Reservation Author: Anglin, Donald R Year: 1994, 2007, 2006 ABSTRACT The U.S. Fish and Wildlife Service, Lower Columbia River Fishery Resource Office was funded by Bureau of Indian Affairs to conduct an instream flow assessment for the lower Klamath River within the Yurok Indian Reservation in northern California using the Instream Flow Incremental Methodology (IFIM). Specific study tasks consisted of developing an explicit statement of purpose, definition of the study area and target species, assembly and evaluation of hydrologic, water quality, and physical data as well as biological and fish habitat information. A reconnaissance survey of the proposed study area was also conducted. The purpose for conducting the proposed flow study was the Yurok Tribe's desire to protect the Klamath basin water supply for the production of anadromous fish. The ultimate goal was to protect, restore, and enhance the anadromous fishery resources on the Reservation and in the basin as a whole. The study area was defined as the lower Klamath River and tributaries from the confluence with the Trinity River downstream to the area of tidal influence. Although the mainstem Klamath only was proposed for flow studies, the tributaries were included in the study area as a result of their hydrologic and biological relevance. Target species were identified as chinook salmon {Oncorhynchus tshawytscha), coho salmon (0. kisutch), steelhead trout (0. mykiss) , green sturgeon {Acipenser medirostris) , eulachon (Thaleichthys pacificus) , and Pacific lamprey (Lampetra tridentata) . Assembly and evaluation of relevant information was accomplished from results of a public scoping meeting and the review of a large volume of both published and file reports as well as numerous personal communications. Hydrology of the lower Klamath River is affected by U.S. Bureau of Reclamation projects in both the upper Klamath and upper Trinity subbasins. Several hydroelectric projects in the upper Klamath subbasin affect flow patterns, and agricultural activities in the upper Klamath subbasin and tributaries and the Central Valley Project in the upper Trinity subbasin have reduced water yield from the basin. Water quality concerns were identified as elevated water temperatures and nutrient levels resulting from land use activities throughout the basin. Hydrologic and water quality impacts are partially mitigated in the lower Klamath by tributary inflow throughout the basin. The physical environment in the basin has been altered by land use practices and several major flood events. Alterations include loss of riparian vegetation and stream channel stability, loss of soil moisture storage capacity and infiltration potential, debris slides and logjams resulting in migration barriers, reduced supply of large woody debris for recruitment into the stream channel, and sedimentation of spawning and rearing habitat. Fish habitat in most lower Klamath tributaries has been surveyed and deficiencies as well as good quality habitat have been described. Significant production potential exists in most tributaries, however much restoration work needs to be completed to realize the potential.

  	Citation × Citation Citation Abstract Copy Title: Biological assessment of the Klamath Project's continuing operations on southern Oregon/Northern California esu coho salmon and critical habitat for southern Oregon/northern California esu coho salmon Year: 2001, 2004 The Bureau of Reclamation (Reclamation) is the responsible Federal agency for operation of the Klamath Project (Project). Operation of the Project has been the subject of numerous previous consultations with the U.S. Fish and Wildlife Service (Service) and one with the National Marine Fisheries Service (NMFS) under Section 7 of the Endangered Species Act (ESA). Severe drought conditions in 1992 and 1994 and resultant associated shortages in project water supplies coupled with the 1997 listing of the southern Oregon/northern California (SONCC) coho salmon, Oncorhynchus kisutch, as threatened in the Klamath River downstream from the Project led to a review of Reclamation 19s operations. This biological assessment (BA) describes the effects on federally-listed species (i.e., coho salmon) and its designated critical habitat from on-going operation of the project based on historic operations, as described in this BA. The biological opinion (BO) addressing this BA and any subsequent BA amendments will be among the information that will inform the development of alternatives of the long-term operations plan and environmental impact statement (EIS). Reclamation is developing a long-term operations plan and EIS for the Project. The preferred alternative for implementation from the long-term operations plan would be the subject of a separate future ESA consultation. This BA describes the needs of anadromous fish with emphasis on SONCC coho salmon. It was developed using the best available scientific and commercial information on anadromous fish in the Klamath River. Coho salmon were listed as threatened on June 6, 1997 (NMFS 1997). The NMFS published a final rule designating critical habitat for SONCC coho salmon in May, 1999 (NMFS 1999a). Designated critical habitat for SONCC coho salmon encompasses accessible reaches of all rivers (including estuarine areas and tributaries) between the Mattole River in California and the Elk River in Oregon. Critical habitat includes all waterways, substrate, and adjacent riparian zones below longstanding, naturally impassable barriers. The areas upstream from Iron Gate Dam (IGD) (river mile 190) were not proposed critical habitat because areas downstream were considered sufficient for the conservation of the species. Reclamation has not evaluated whether the action that is the subject of this BA is consistent with its trust responsibility to Klamath Basin Indian Tribes. There are several important scientific reports and analyses (e.g., Phase II flow study) currently not available to Reclamation concerning threatened coho salmon, their habitat, and water quality as it relates to appropriate river flows that may be necessary to operate the Project consistent with the trust responsibility to Klamath Basin Indian Tribes. When this additional information becomes available, Reclamation intends to consider it during the development of the Project operations plans and include it in subsequent consultations with NMFS, as appropriate.

  	Citation × Citation Citation Abstract Copy Title: Nutrient loading of surface waters in the Upper Klamath Basin : agricultural and natural sources Author: Rykbost, K. A. Year: 2001, 2004 Abstract Implementation of the Federal Clean Water Act and Oregon Senate Bill 1010 is proceeding under two simultaneous processes in Oregon. The Oregon Department of Environmental Quality is responsible for developing Total Maximum Daily Load (TMDL) allocations for water-quality limited water bodies. The Oregon Department of Agriculture is striving to develop Management Area Plans to provide guidance for management of private agricultural lands to meet Clean Water Act objectives. Both processes seek input from local advisory committees comprised of landowners and other stakeholders, and technical review committees. Klamath Lake and Klamath River have been designated water quality impaired for several parameters including nutrients. Researchers have attempted to determine the extent of agriculture's contributions to nutrient enrichment of surface waters in the Upper Klamath Basin. Two United States Geological Survey (USGS) studies focused attention on drainage of agricultural lands adjacent to Klamath Lake as a significant source of nutrient loading in the lake. A preliminary draft report by the Klamath River TMDL committee identified the outlet for drainage waters from the Klamath Irrigation Project to the Klamath River at the Straits Drain as a point source for nutrient loading. Preparation of a final TMDL for this sub-watershed was tabled pending development of a TMDL for Klamath Lake and its tributaries. Insufficient data are available to determine the relative contributions of agricultural activities, natural background sources, and other potential sources of nutrient enrichment to establish numerical limits for nutrient loading from agricultural lands. From 1998 through 2000, the Klamath Experiment Station has investigated nutrient loading from drainage of agricultural lands adjacent to Klamath Lake, natural background sources including major springs and several artesian wells, and loading to the Klamath Irrigation Project from diversions out of Klamath Lake and Klamath River. Findings indicate contributions from agricultural lands adjacent to Klamath Lake have been overestimated, and the Klamath Irrigation Project is probably a net sink for nutrients diverted out of Klamath Lake and Klamath River. Data to support these assertions are presented. Introduction Most of the surface waters in the Klamath Basin are included in the Oregon department of Environmental Quality (DEQ) 303D list as water-quality limited. While the only criterion for listing of many streams is temperature, based on a preliminary standard of 64°F, Klamath Lake and Klamath River are listed for chlorophyll a, dissolved oxygen, un-ionized ammonia, and pH.

It is my desire to keep you informed about issues, activities, and opportunities I think are important to the public. More importantly, I am seeking ideas and comments from those who may be affected by multiple- use management programs here on the resource area. This planning update is organized to make it easy for you to find projects of most interest. Projects have been arranged into categories ( i. e., Recent Decisions, New Projects, On- going Projects, and Environmental Education Activities). In addition, each of these categories is sorted by resource topics ( e. g., Lands Program, Timber Sales, etc.). The table will give you a brief description of activities occurring within the Klamath Falls Resource Area and for most projects a location. Refer to one of three maps following the table, for locations of projects. Additional information can be obtained fi- om the contact listed in the project descriptions. If you have any concerns about the proposed actions, please call the Klarnath Falls Resource Area and ask for the " Contact" person listed or the Resource Area Planner as soon as possible. The earlier you get involved, the more capability we have to adjust or change planned actions. Also be alert for news releases and public notices published in the Herald and News as projects reach stages for public involvement. If you want to provide comments to a specific environmental assessment, please send or deliver your written comments addressed to the Field Manager, Klamath Falls Resource Area, by the close of, or postmarked by the last day of the comment period. Your comments and concerns are welcomed, and could influence the final decision on these projects. I would appreciate any comments or suggestions you may have regarding this p l h i n g update or how it could be improved to make it more useful to you. Thank you for your continued interest in BLM's management of public lands. If you have any questions on this planning update, stop by the office or call ( 541) 883- 6916.

It is my desire to keep you informed about issues, activities, and opportunities I think are important to the public. More importantly, I am seeking ideas and comments from those who may be affected by multiple- use management programs here on the resource area. This planning update is organized to make it easy for you to find projects of most interest. Projects have been arranged into categories ( i. e., Recent Decisions, New Projects, On- going Projects, and Environmental Education Activities). In addition, each of these categories is sorted by resource topics ( e. g., Lands Program, Timber Sales, etc.). The table will give you a brief description of activities occurring within the Klamath Falls Resource Area and for most projects a location. Refer to one of three maps following the table, for locations of projects. Additional information can be obtained fi- om the contact listed in the project descriptions. If you have any concerns about the proposed actions, please call the Klarnath Falls Resource Area and ask for the " Contact" person listed or the Resource Area Planner as soon as possible. The earlier you get involved, the more capability we have to adjust or change planned actions. Also be alert for news releases and public notices published in the Herald and News as projects reach stages for public involvement. If you want to provide comments to a specific environmental assessment, please send or deliver your written comments addressed to the Field Manager, Klamath Falls Resource Area, by the close of, or postmarked by the last day of the comment period. Your comments and concerns are welcomed, and could influence the final decision on these projects. I would appreciate any comments or suggestions you may have regarding this p l h i n g update or how it could be improved to make it more useful to you. Thank you for your continued interest in BLM's management of public lands. If you have any questions on this planning update, stop by the office or call ( 541) 883- 6916.

Fish and Wildlife Service, Klamath Basin National Wildlife Refuge, Route 1, Box 74, Tulelake, CA 96134 Introduction The Lost River ( Deltistes luxatus) and shortnose ( Chasmistes brevirostris) suckers were federally listed as endangered species on July 18, 1988 ( Federal Register 53: 27130- 27134). Both sucker species are relatively long- lived, have a limited geographic range, and are endemic to the Upper Klamath Basin of Northern California and Southern Oregon. Habitat degradation from water diversions and loss of riparian and wetlands habitats associated with agricultural development within their historic range is believed to be the major reason for the species decline ( U. S. Fish and Wildlife Service 1993). A more detailed description on the life history, habitat requirements, and causes of decline of the species can be found in the Lost River and Shortnose Sucker Recovery Plan ( U. S. Fish and Wildlife Service 1993). Tule Lake National Wildlife Refuge ( NWR), established in 1928, consists of 2 return flow sumps ( Sump 1( A) and 1( B)) totaling 13,000 acres surrounded by 17,000 acres of intensively farmed lands ( Fig. 1). The refuge and surrounding private agricultural lands occupy the historic lake bed of Tule Lake, a 95,000 acre lake and marsh area that was reclaimed in the early 1900fs as part of the Klamath Reclamation Project. Current management of the refuge is directed by the Kuchel Act of 1964 which mandates the refuge be managed for the major purpose of waterfowl management but with optimal agricultural use that is consistent therewith. Both sumps are shallow ( 0.1 - 2.0 m) and consist of approximately 10,500 acres of open water with a 2,500 acre shallow (< 0.1 m) emergent marsh at the northeast corner of Sump 1( A). Tule Lake has been identified as a potential refugia for both sucker species ( U. S. Fish and Wildlife Service 1993). Tule T like National Wildlife Sump 3 Lease lands Field . Station Cocbetative Fanning Fields Area J Lease Lands Sump 2 I ease I , ands Figure 1. Tule Lake National Wildlife Refuge, California. During winter, water within the sumps is comprised primarily of local runoff and during summer water is comprised primarily of irrigation return flows, originating from Upper Klamath Lake. Summer water quality in the sumps is similar to other water bodies within the Upper Klamath Basin and is considered hypereutrophic ( Dileanis et al. 1996). Water quality problems include low dissolved oxygen ( DO) and high hydrogen ion concentrations ( pH) and unionized ammonia. Water quality in the Tule Lake sumps is directly affected by hypereutrophic conditions in Upper Klamath Lake ( U. S. Fish and Wildlife Service 1993). Studies conducted after publication of the Shortnose and Lost River Sucker Recovery Plan indicate that Tule Lake contains an estimated 159 ( 95% CI = 48- 289) shortnose and 105 ( 95% CI = 25- 175) Lost River suckers ( Scoppetone and Buettner 1995). Confidence intervals for these estimates are large because of small sample sizes and low rates of recapture. Recruitment rates for the Tule Lake population via spawning below Anderson- Rose Dam is low with significant larval production occurring only in 1995 ( monitoring occurred 1991- 99) ( M. Buettner, pers. comm). Entrainment from the irrigation system is likely the largest source offish for Tule Lake ( U. S. Bureau of Reclamation 1998). Both species of suckers in Tule lake are in good physical condition relative to fish in Clear Lake and Upper Klamath Lake with Tule Lake fish being generally heavier and exhibiting few if any problems with parasites or lamprey. ( Scoppetone and Buettner 1995). U. S. Bureau of Reclamation ( Reclamation) biologists tracked 10 radio- marked suckers in Tule Lake from 1993- 95. From these studies, specific use areas by time period were identified with over 99% of radio locations occurring in Sump 1( A). Of particular importance from these studies was identification of an over- summer site in the south central region of Sump 1( A) termed the ADonut Hole# ( DH). In early 1999, the U. S. Fish and Wildlife Service ( Service) proposed a wetland enhancement project on the 3,500 acre Sump 1( B). The project was designed to improve habitat for waterfowl and other associated wetland species as well as improve water quality through the conversion of Sump 1( B) from an open body of shallow water to an emergent year- round flooded wetland. The primary mechanism to create the desired habitat condition is a series of annual spring/ summer drawdowns thereby creating conditions suitable for germination of desired emergent plant species. Of principal concern in developing the project was the potential effects on suckers within the sumps. Because of the proximity of both sucker species in adjacent Sump 1( A), a project monitoring plan was developed to ascertain the potential effects of the Sump 1( B) Project on suckers and water quality. Our monitoring design benefitted from studies of water quality and sucker movements by Reclamation biologists from 1992- 95. This report summarizes findings of the first year= s pre- project monitoring effort ( April- December, 1999) relative to water quality and movements of radio- marked suckers. Objectives 1. Describe seasonal distribution and movement patterns of both sucker species in Tule Lake NWR and determine if fish movements have changed since initial studies by Reclamation biologists in 1993- 95. 2. Characterize water quality, in space and time, of areas used by adult suckers compared to areas which are not used. 3. Document and describe movements of radio- marked suckers to spawning areas below Anderson- Rose dam. 4. Determine whether recruitment of larvae and juvenile was occurring below Anderson- Rose Dam. Methods Monitoring radio- marked adult suckers In April and May, 1999, Reclamation biologists captured 14 suckers and surgically implanted radio- transmitters ( ATS, Isanti, MN) having a projected battery life of 12 months. Each transmitter had an external antennae that exited the body cavity near the lateral line of the fish. Eleven Lost River and 3 shortnose suckers were captured using trammel nets at the northwest corner of Sump 1( A) ( 9 fish) and immediately downstream of Anderson- Rose Dam on the Lost River ( 5 fish) ( Table 1). We located radio- marked fish via air thrust boats using a scanning receiver and 4- element yagi antennae. Fish were located fish 4 times/ month during March and April, 2 times/ month from May through September, and once per month from October through December. Fish not located via boat were located from fixed wing aircraft. We determined fish locations by moving as close as possible to undisturbed fish and recording locations with a Global Positioning System ( GPS). All GPS positions consisted of 180 rover points/ location and were differentially corrected via post processing software ( PFinder ver. 2.11). We recorded depth information at each fish location. To determine timing and duration of the spawning migration, we monitored radio-marked fish from vehicles on the east levee of the Lost River downstream of Anderson- Rose Dam. Table 1.

Egg viability surveys were conducted in the gravel sediments immediately below the dam in May. Water quality We preselected water quality sampling sites ( Fig. 2, Table 2) in Sump 1( A) to correspond to adult sucker use areas as determined by studies of radio- marked adult suckers conducted by Reclamation in 1993- 95 ( Fig. 3). We selected 2 sites in Sump 1( B) which met or exceeded the minimum depth requirement (> 3ft) for both sucker species ( M. Buettner, pers. comm.) after referring to 1986 bathymetric maps. We attempted to obtain data from each site twice/ month. We moved 2 sample sites ( Donut Hole and Donut Hole Northwest) early in the summer and 1 site ( Donut Hole West) ( Fig. 2) during mid- summer to better represent summer use locations of radio- marked fish. From May through November, we measured water quality parameters ( dissolved oxygen ( DO), hydrogen ion concentration ( pH), and temperature (° C)) using DataSonde 3, 4 and 4a= s ( Hydrolab Corp., Austin, Texas) ( hereafter referred to as Hydrolabs) 26 cm ( 12 in) above the sediment. We suspended Hydrolabs, within PVC tubes, from metal fence posts driven into the sediment. Data were collected hourly over a 96 hr period at each monitoring site. We downloaded data from Hydrolabs using the Hyperterminal software package v. 690170 to a personal computer. Unit probes were cleaned and calibrated according to Hydrolab guidelines ( Hydrolab Corporation 1997) and local geographic standards. Using the same deployment schedule as with our Hydrolabs, we sampled turbidity at each site using a Portable Turbidimeter model 21 OOP ( Hach Corp., P. O. Box 389, Loveland, CO 80539). We collected water samples 27 cm ( 12 in) above the sediment at each sample site. We measured turbidity in NTUs, following the guidelines in the product manual and we measured water depth using a hand- crafted wooden pole, marked in measured increments. We summarized water quality data using Microsoft 8 EXCEL software v. 97 SR- 1 and SPSS for Windows release 9.0.0. Because of the apparent difference in summer water quality in the DH versus other sampling sites, data were summarized as DH sites and Non- DH ( NDH) sites.

Results Radio- marked suckers We located fish 231 times in locations similar to those determined by Reclamation biologists in 1993- 95 ( Figs 3- 4). Lost River and shortnose suckers did not appear to differentiate use of the sump by species; we located both species intermixed throughout the monitoring period. With the exception DH and DHNW ( Fig. 2), water quality sampling sites were close to seasonal sucker use areas. Of 14 suckers marked, mortality occurred in only 1 fish. A Lost River sucker (# X9) was tagged on 18 May at the Anderson Rose Dam; she was not located again until 23 days later on 9 June. From 9 June to 17 November, # X9 was located by signal within approximately 15 m of the original location based on the location data. It is likely that this fish died in early June within 2- 3 weeks of being radio- marked. It is unknown if this mortality was related to the stress of handling and marking or some other cause. April - May - In April- May, a period of maximum fish movements ( Figs. 5- 18), most suckers congregated in the AEnglish Channel ® between the sumps with a scattering offish located between the northwest corner of Sump 1( A) and the AEnglish Channel ® ( Fig. 4). Only 1 fish radio- marked in Tule Lake moved into the Lost River. This particular fish, a female shortnose sucker (# G9) was radio- marked in the northwest corner of Tule Lake on 9 April, was located in the AEnglish Channel ® on 14 April, and subsequently was located in Lost River below Anderson Rose Dam on 29 April and 6 May.

Movements of radio- marked sucker X9 on Tule Lake National Wildlife Refuge, California, 1999. 25 June - September - During this period, nearly all suckers ( particularly during July and August) could be found in the DH at the south central portion of Sump 1( A) ( Fig. 4). By connecting the outermost locations of approximately 90% of radio locations, the calculated area of the DH was 188 ha. Suckers using the DH were found in depths ranging from 1.0- 1.3 m ( 39- 50 in) ( Fig. 19). September - December - During this period suckers moved from the DH to the northwest corner of Sump 1( A). As of the writing of this report, ( February 15, 2000) the 13 remaining fish occupy the same area. Recruitment Surveys by Reclamation biologists for larval and juvenile suckers in the Lost River below Anderson- Rose Dam failed to document the presence young of the year fish. Below is a summary of surveys: Date 5/ 25/ 99 6/ 2/ 99 6/ 10/ 99 Result Searches for eggs in gravel below Anderson- Rose Dam revealed eggs in 4 of 5 sites, some of which were viable. Larval surveys conducted at 3 sites ( visual and dip net) from the dam to the wooden bridge were negative. Larval surveys conducted at 5 sites including the dam, 2 and 1 mile downstream, the wooden bridge, and East- West Road were negative. Larval surveys conducted at 2 sites downstream of dam were negative. Water quality pHBln general, pH values were less variable in the DH then areas outside this region ( Fig. 20). In all areas, median pH values remained below 9.5 until early June at which time values outside the DH were frequently above 10.0. pH values were particularly high (> 10.0) in late June through August in ESIB and NWS1A and periodically in the EC and WS1B. pH values in the DH and areas adjacent, remained below 10.0 through September; however, there was a gradual rise in pH values in DH sites from May through September. In late September and early October, DH pH values exceeded all other sites. rem/ reratareBTemperatures in all regions reached a peak in late July through early August with no discernible difference between DH or NDH sites ( Fig. 21). Dissolved oxvgenBDonut Hole sampling station s differed in dissolved oxygen characteristics relative to other areas of the sumps. During the June through August period DH sites ranged from 4.5 to 11.2 mg/ 1 while areas outside this region ranged from 1.1 mg/ 1 to 18.2 mg/ 1 ( Fig. 21). Toward November DH and NDH sites became similar DO dynamics ( Fig. 21). 26 Turbiditvllln general, turbidity values appeared greater in the DH versus areas outside, although some sites particularly in Sump 1( B) were quite variable particularly in June and July. This may have been due to the large amount of filamentous algae in Sump 1( B), potentially interfering with the measurement. Turbidity rose sharply at sites by late October and November ( Fig. 23- 24). 20 >• 1 5 O UJ a UJ DC 10 0 39 41 43 45 47 More DEPTH Figure 19.

Turbidity at non- Donut Hole sites on Tule Lake National Wildlife Refuge, California, 1999. 33 Discussion Water Quality The area of the DH was delineated from plotted June through September locations of radio-marked suckers ( approximately 188 ha.). The location of the DH could also be seen as an area of relatively turbid water from aerial photographs from August 1998 ( Fig. 25) as well as aerial photographs taken in 1984. It is possible that the combination of 2 factors may cause the observed turbidity in the DH. First, seeps or springs may be present in the area which result in more favorable water quality during summer which attracts suckers as well as other fish species to the area. The resultant concentration offish ( suckers and chubs) may stir the sediments during feeding activities, thereby creating the observed turbidity. The additional turbidity in the DH may inhibit light penetration and the production of algae, thereby reducing photo synthetically elevated pH and the extreme minimum and maximums in DO typical of may water bodies in the Klamath Basin including Tule Lake ( Dileanis et al. 1996). The rise in turbidity at all sites in fall is likely due to the break down of rooted aquatic vegetation which then allows for wind induced wave action to stir the sediments. Other than the DH, all other sites had dense concentrations of rooted aquatic plants and/ or filamentous green algae during summer. June to September DO and pH dynamics in the DH appeared different than at NDH sites ( Figs. 20 and 22). The difference was greatest in early summer with the difference becoming smaller by late summer and essentially disappearing by fall. Whether this water quality difference was a result of the more turbid waters or inflow from springs is unknown. However, attempts by Service hydrologists to model inflows, evapotranspiration, and outflows from the sumps have resulted in a positive imbalance of approximately 21,000 acre- feet of water from April through September. This positive imbalance is greatest in spring and early summer, gradually lessening by summer and essentially disappearing by fall ( Tim Mayer, pers. comm.). If this inflow is occurring, it may explain differences in summer water quality between DH and NDH sites. June to September water quality in the DH may be critical to the over summer survival of suckers in Tule Lake as pH and DO in NDH sites during summer often exceeded the tolerance limits for the fish. DO and pH levels at DH sites were less variable and did not reach the extremes that were reached in NDH sites. The lowest DO measured during June through September at DH sites were 4.83 mg/ 1 ( DHWEST) and 4.96 mg/ 1 ( DHEAST). DO and pH during summer from this study were similar to values collected by Reclamation in 1992 ( Table 3). Buettner and Scoppettone ( 1990) found juvenile suckers only where DO was above 4.5 mg/ 1. It is currently believed that adult suckers become stressed at DO levels below 4.0 mg/ 1 with mortality occurring at or below 2.0 mg/ 1 ( M. Buettner, pers. comm.). The relatively high over- summer survival of radio- marked suckers, compared to suckers radio- marked in Upper Klamath Lake ( M. Buettner, pers. comm), is further evidence of suitable summer water quality conditions in the DH on Tule Lake. 34 Figure 25. " Donut Hole" in Sump 1( A) of Tule Lake NWR.

( Data from U. S. Bureau of Reclamation) pH levels in the DH generally remained below 10.0 whereas non DH sites frequently exceeded 10.0 ( Fig. 19). Falter and Cech ( 1991) determined a maximum pH tolerance in shortnose suckers of 9.55+ 0.43 under laboratory conditions, levels generally exceeded in June - September at non DH sites and some DH sites in late summer. Buettner and Scoppettone ( 1990) found juvenile fish in Upper Klamath Lake largely at sites with pH < 9.0, as did Simon et al. ( 1996) in 1994. However, in 1995, Simon et al. ( 1996) found that most juvenile fish ( 54%) were captured in areas of higher pH (> 10.0). Laboratory studies indicate significant mortality of larval and juvenile fish at high pH values (> 9.55) ( Falter and Cech 1991) and 9.92- 10.46 ( Bellerud and Saiki 1995). Previous water quality and fish health studies on the refuge determined that water quality conditions were stressful to aquatic life and was resulting in a high ( up to 37%) proportion offish with deformities ( Dileanis et al. 1996), however, studies of sucker ecology in Tule Lake have indicated that individual fish in the lake have a high condition factor and are free of external parasites ( Scoppettone and Buettner 1995). Bennet ( 1994) recognized this apparent inconsistency, stating, A... the observation that Tule Lake suckers are in better physical condition than Upper Klamath Lake suckers indicates that certain areas of the aquatic system may be of particular importance for the recovery of those species. ® In the case of Tule Lake this Acertain area@ is likely the DH.. Suckers in Tule Lake may be in good condition because of their limited population size, the abundant food resources in this lake, and adequate water quality ( in the DH) to survive the summer period. 36 Sucker movements Although, suckers were relatively sedentary during most periods of the year, they exhibited the ability to make long distance moves in relatively short periods of time, particularly during the April spawning period. The northwest corner of Sump 1( A) receives about 90% of the inflow from the Lost River and spring winds on Tule Lake tend to move large quantities of water through the AEnglish Channels back and forth between Sump 1( A) and 1( B). This movement of water at both locations may explain the movement of fish observed in April and May. Suckers may be attracted to both locations when seeking spawning habitat in spring. Recruitment During the April marking period, most captured suckers appeared to be physiologically ready to spawn; however, only one fish moved into the river. Of 10 radio- marked fish monitored by Reclamation in 1993- 95 no fish attempted to run the Lost River. This low proportion offish that attempt to spawn may have one or several causes or a combination, including: 1. Stress of handling and implanting radio- transmitters so close to the spawning season may prevent fish from becoming reproductively active. 2. Under normal conditions, only a small proportion of Tule Lake suckers may attempt to spawn in any particular year. 3. Flow conditions in or at the mouth of the Lost River may be inadequate to draw the fish into the river. 4. A shallow bar (< 0.3 m) of deposited silt exists between the lake and the mouth of the river which may form a physical barrier to the fish. At the present time, a mandated flow of 30 cfs is released below Anderson- Rose Dam to provide spawning habitat at the Dam. Although this flow is intended to provide suitable spawning conditions at the Dam, these flows may be inadequate to entice fish into the river. It is likely that the historic spring flows in the Lost River were many times higher than current regulated flows. However, given that the fish are largely unsuccessful in spawning and risk additional mortality traversing the river, adult survival may be enhanced by remaining in the lake. Scoppettone and Buettner ( 1995) also observed no radio- marked fish from Clear Lake to move into Willow Creek during the spring spawning period. In this case the authors attributed this result to either capture stress or low stream flows during spring. 37 Habitat use Although the DH is relatively shallow relative to other areas of Tule Lake, use of the DH may be mandatory to ensure over- summer survival. Although deeper waters are available to the fish, especially in the northwest corner of Sump 1( A), DO levels, in particular, likely preclude their use. Suckers did not move out of the DH until October when DO levels began to rise with cooler water temperatures. Although, Sump 1( B) contained suitable water depths and water quality conditions in fall, no suckers were located in this area. It is possible that suckers may prefer not to pass through the pipes connecting the Sumps or the proximity and flow from the Lost River in the northwest corner of Sump 1( A) may make this area more attractive as an over- winter habitat area. The relative lack of water depth in the DH as well as other areas of the sumps is becoming of increasing concern because of the loss of water depth through sedimentation. If suckers require a minimum of 3 ft of water, as is current believed ( M. Buettner, pers. comm.), current rates of sedimentation in the sumps threaten the future suitability of Tule Lake for suckers. Based on a comparison of bathymetric surveys conducted by Reclamation in 1958 and again in 1986, sedimentation has been steadily reducing the water holding capacity of both sumps. Between the 1958 and 1986 surveys ( 28 years), Sump 1( A) has lost 22.4% of its water capacity and Sump 1( B) has lost 30.8% of its capacity due to sedimentation. This would indicate a total mean sedimentation of 11.8 inches over this time period ( U. S. Bureau of Reclamation, unpubl. rep). Over the last several years, an attempt has been made to store additional water in Tule Lake during summer by raising water levels above 4034.60 ft. This increase in water elevations ( between 4034.60 and 4034.90 ft) has somewhat mitigated the loss of depth through sedimentation. However, without reinforcing and raising the levees around the sumps, there is a limit as to how high water elevations can rise. At elevation 4035.50 ft., operating regulations require breaching the sumps into overflow areas ( Sump 2 or 3). Although increased summer operating levels may assist the fish, they may also increase the risk of a flood event requiring the breaching of the sumps with potentially negative impacts to the fish.

Fish and Wildlife Service, Klamath Basin National Wildlife Refuge, Route 1, Box 74, Tulelake, CA 96134 Introduction The Lost River ( Deltistes luxatus) and shortnose ( Chasmistes brevirostris) suckers were federally listed as endangered species on July 18, 1988 ( Federal Register 53: 27130- 27134). Both sucker species are relatively long- lived, have a limited geographic range, and are endemic to the Upper Klamath Basin of Northern California and Southern Oregon. Habitat degradation from water diversions and loss of riparian and wetlands habitats associated with agricultural development within their historic range is believed to be the major reason for the species decline ( U. S. Fish and Wildlife Service 1993). A more detailed description on the life history, habitat requirements, and causes of decline of the species can be found in the Lost River and Shortnose Sucker Recovery Plan ( U. S. Fish and Wildlife Service 1993). Tule Lake National Wildlife Refuge ( NWR), established in 1928, consists of 2 return flow sumps ( Sump 1( A) and 1( B)) totaling 13,000 acres surrounded by 17,000 acres of intensively farmed lands ( Fig. 1). The refuge and surrounding private agricultural lands occupy the historic lake bed of Tule Lake, a 95,000 acre lake and marsh area that was reclaimed in the early 1900fs as part of the Klamath Reclamation Project. Current management of the refuge is directed by the Kuchel Act of 1964 which mandates the refuge be managed for the major purpose of waterfowl management but with optimal agricultural use that is consistent therewith. Both sumps are shallow ( 0.1 - 2.0 m) and consist of approximately 10,500 acres of open water with a 2,500 acre shallow (< 0.1 m) emergent marsh at the northeast corner of Sump 1( A). Tule Lake has been identified as a potential refugia for both sucker species ( U. S. Fish and Wildlife Service 1993). Tule T like National Wildlife Sump 3 Lease lands Field .

During winter, water within the sumps is comprised primarily of local runoff and during summer water is comprised primarily of irrigation return flows, originating from Upper Klamath Lake. Summer water quality in the sumps is similar to other water bodies within the Upper Klamath Basin and is considered hypereutrophic ( Dileanis et al. 1996). Water quality problems include low dissolved oxygen ( DO) and high hydrogen ion concentrations ( pH) and unionized ammonia. Water quality in the Tule Lake sumps is directly affected by hypereutrophic conditions in Upper Klamath Lake ( U. S. Fish and Wildlife Service 1993). Studies conducted after publication of the Shortnose and Lost River Sucker Recovery Plan indicate that Tule Lake contains an estimated 159 ( 95% CI = 48- 289) shortnose and 105 ( 95% CI = 25- 175) Lost River suckers ( Scoppetone and Buettner 1995). Confidence intervals for these estimates are large because of small sample sizes and low rates of recapture. Recruitment rates for the Tule Lake population via spawning below Anderson- Rose Dam is low with significant larval production occurring only in 1995 ( monitoring occurred 1991- 99) ( M. Buettner, pers. comm). Entrainment from the irrigation system is likely the largest source offish for Tule Lake ( U. S. Bureau of Reclamation 1998). Both species of suckers in Tule lake are in good physical condition relative to fish in Clear Lake and Upper Klamath Lake with Tule Lake fish being generally heavier and exhibiting few if any problems with parasites or lamprey. ( Scoppetone and Buettner 1995). U. S. Bureau of Reclamation ( Reclamation) biologists tracked 10 radio- marked suckers in Tule Lake from 1993- 95. From these studies, specific use areas by time period were identified with over 99% of radio locations occurring in Sump 1( A). Of particular importance from these studies was identification of an over- summer site in the south central region of Sump 1( A) termed the ADonut Hole# ( DH). In early 1999, the U. S. Fish and Wildlife Service ( Service) proposed a wetland enhancement project on the 3,500 acre Sump 1( B). The project was designed to improve habitat for waterfowl and other associated wetland species as well as improve water quality through the conversion of Sump 1( B) from an open body of shallow water to an emergent year- round flooded wetland. The primary mechanism to create the desired habitat condition is a series of annual spring/ summer drawdowns thereby creating conditions suitable for germination of desired emergent plant species. Of principal concern in developing the project was the potential effects on suckers within the sumps. Because of the proximity of both sucker species in adjacent Sump 1( A), a project monitoring plan was developed to ascertain the potential effects of the Sump 1( B) Project on suckers and water quality. Our monitoring design benefitted from studies of water quality and sucker movements by Reclamation biologists from 1992- 95. This report summarizes findings of the first year= s pre- project monitoring effort ( April- December, 1999) relative to water quality and movements of radio- marked suckers. Objectives 1. Describe seasonal distribution and movement patterns of both sucker species in Tule Lake NWR and determine if fish movements have changed since initial studies by Reclamation biologists in 1993- 95. 2. Characterize water quality, in space and time, of areas used by adult suckers compared to areas which are not used. 3. Document and describe movements of radio- marked suckers to spawning areas below Anderson- Rose dam. 4. Determine whether recruitment of larvae and juvenile was occurring below Anderson- Rose Dam. Methods Monitoring radio- marked adult suckers In April and May, 1999, Reclamation biologists captured 14 suckers and surgically implanted radio- transmitters ( ATS, Isanti, MN) having a projected battery life of 12 months. Each transmitter had an external antennae that exited the body cavity near the lateral line of the fish. Eleven Lost River and 3 shortnose suckers were captured using trammel nets at the northwest corner of Sump 1( A) ( 9 fish) and immediately downstream of Anderson- Rose Dam on the Lost River ( 5 fish) ( Table 1). We located radio- marked fish via air thrust boats using a scanning receiver and 4- element yagi antennae. Fish were located fish 4 times/ month during March and April, 2 times/ month from May through September, and once per month from October through December. Fish not located via boat were located from fixed wing aircraft. We determined fish locations by moving as close as possible to undisturbed fish and recording locations with a Global Positioning System ( GPS). All GPS positions consisted of 180 rover points/ location and were differentially corrected via post processing software ( PFinder ver. 2.11). We recorded depth information at each fish location. To determine timing and duration of the spawning migration, we monitored radio-marked fish from vehicles on the east levee of the Lost River downstream of Anderson- Rose Dam. Table 1.

Egg viability surveys were conducted in the gravel sediments immediately below the dam in May. Water quality We preselected water quality sampling sites ( Fig. 2, Table 2) in Sump 1( A) to correspond to adult sucker use areas as determined by studies of radio- marked adult suckers conducted by Reclamation in 1993- 95 ( Fig. 3). We selected 2 sites in Sump 1( B) which met or exceeded the minimum depth requirement (> 3ft) for both sucker species ( M. Buettner, pers. comm.) after referring to 1986 bathymetric maps. We attempted to obtain data from each site twice/ month. We moved 2 sample sites ( Donut Hole and Donut Hole Northwest) early in the summer and 1 site ( Donut Hole West) ( Fig. 2) during mid- summer to better represent summer use locations of radio- marked fish. From May through November, we measured water quality parameters ( dissolved oxygen ( DO), hydrogen ion concentration ( pH), and temperature (° C)) using DataSonde 3, 4 and 4a= s ( Hydrolab Corp., Austin, Texas) ( hereafter referred to as Hydrolabs) 26 cm ( 12 in) above the sediment. We suspended Hydrolabs, within PVC tubes, from metal fence posts driven into the sediment. Data were collected hourly over a 96 hr period at each monitoring site. We downloaded data from Hydrolabs using the Hyperterminal software package v. 690170 to a personal computer. Unit probes were cleaned and calibrated according to Hydrolab guidelines ( Hydrolab Corporation 1997) and local geographic standards. Using the same deployment schedule as with our Hydrolabs, we sampled turbidity at each site using a Portable Turbidimeter model 21 OOP ( Hach Corp., P. O. Box 389, Loveland, CO 80539). We collected water samples 27 cm ( 12 in) above the sediment at each sample site. We measured turbidity in NTUs, following the guidelines in the product manual and we measured water depth using a hand- crafted wooden pole, marked in measured increments. We summarized water quality data using Microsoft 8 EXCEL software v. 97 SR- 1 and SPSS for Windows release 9.0.0. Because of the apparent difference in summer water quality in the DH versus other sampling sites, data were summarized as DH sites and Non- DH ( NDH) sites.

Results Radio- marked suckers We located fish 231 times in locations similar to those determined by Reclamation biologists in 1993- 95 ( Figs 3- 4). Lost River and shortnose suckers did not appear to differentiate use of the sump by species; we located both species intermixed throughout the monitoring period. With the exception DH and DHNW ( Fig. 2), water quality sampling sites were close to seasonal sucker use areas. Of 14 suckers marked, mortality occurred in only 1 fish. A Lost River sucker (# X9) was tagged on 18 May at the Anderson Rose Dam; she was not located again until 23 days later on 9 June. From 9 June to 17 November, # X9 was located by signal within approximately 15 m of the original location based on the location data. It is likely that this fish died in early June within 2- 3 weeks of being radio- marked. It is unknown if this mortality was related to the stress of handling and marking or some other cause. April - May - In April- May, a period of maximum fish movements ( Figs. 5- 18), most suckers congregated in the AEnglish Channel ® between the sumps with a scattering offish located between the northwest corner of Sump 1( A) and the AEnglish Channel ® ( Fig. 4). Only 1 fish radio- marked in Tule Lake moved into the Lost River. This particular fish, a female shortnose sucker (# G9) was radio- marked in the northwest corner of Tule Lake on 9 April, was located in the AEnglish Channel ® on 14 April, and subsequently was located in Lost River below Anderson Rose Dam on 29 April and 6 May.

Movements of radio- marked sucker X9 on Tule Lake National Wildlife Refuge, California, 1999. 25 June - September - During this period, nearly all suckers ( particularly during July and August) could be found in the DH at the south central portion of Sump 1( A) ( Fig. 4). By connecting the outermost locations of approximately 90% of radio locations, the calculated area of the DH was 188 ha. Suckers using the DH were found in depths ranging from 1.0- 1.3 m ( 39- 50 in) ( Fig. 19). September - December - During this period suckers moved from the DH to the northwest corner of Sump 1( A). As of the writing of this report, ( February 15, 2000) the 13 remaining fish occupy the same area. Recruitment Surveys by Reclamation biologists for larval and juvenile suckers in the Lost River below Anderson- Rose Dam failed to document the presence young of the year fish. Below is a summary of surveys: Date 5/ 25/ 99 6/ 2/ 99 6/ 10/ 99 Result Searches for eggs in gravel below Anderson- Rose Dam revealed eggs in 4 of 5 sites, some of which were viable. Larval surveys conducted at 3 sites ( visual and dip net) from the dam to the wooden bridge were negative. Larval surveys conducted at 5 sites including the dam, 2 and 1 mile downstream, the wooden bridge, and East- West Road were negative. Larval surveys conducted at 2 sites downstream of dam were negative. Water quality pHBln general, pH values were less variable in the DH then areas outside this region ( Fig. 20). In all areas, median pH values remained below 9.5 until early June at which time values outside the DH were frequently above 10.0. pH values were particularly high (> 10.0) in late June through August in ESIB and NWS1A and periodically in the EC and WS1B. pH values in the DH and areas adjacent, remained below 10.0 through September; however, there was a gradual rise in pH values in DH sites from May through September. In late September and early October, DH pH values exceeded all other sites. rem/ reratareBTemperatures in all regions reached a peak in late July through early August with no discernible difference between DH or NDH sites ( Fig. 21). Dissolved oxvgenBDonut Hole sampling station s differed in dissolved oxygen characteristics relative to other areas of the sumps. During the June through August period DH sites ranged from 4.5 to 11.2 mg/ 1 while areas outside this region ranged from 1.1 mg/ 1 to 18.2 mg/ 1 ( Fig. 21). Toward November DH and NDH sites became similar DO dynamics ( Fig. 21). 26 Turbiditvllln general, turbidity values appeared greater in the DH versus areas outside, although some sites particularly in Sump 1( B) were quite variable particularly in June and July. This may have been due to the large amount of filamentous algae in Sump 1( B), potentially interfering with the measurement. Turbidity rose sharply at sites by late October and November ( Fig. 23- 24). 20 >• 1 5 O UJ a UJ DC 10 0 39 41 43 45 47 More DEPTH Figure 19.

Turbidity at non- Donut Hole sites on Tule Lake National Wildlife Refuge, California, 1999. 33 Discussion Water Quality The area of the DH was delineated from plotted June through September locations of radio-marked suckers ( approximately 188 ha.). The location of the DH could also be seen as an area of relatively turbid water from aerial photographs from August 1998 ( Fig. 25) as well as aerial photographs taken in 1984. It is possible that the combination of 2 factors may cause the observed turbidity in the DH. First, seeps or springs may be present in the area which result in more favorable water quality during summer which attracts suckers as well as other fish species to the area. The resultant concentration offish ( suckers and chubs) may stir the sediments during feeding activities, thereby creating the observed turbidity. The additional turbidity in the DH may inhibit light penetration and the production of algae, thereby reducing photo synthetically elevated pH and the extreme minimum and maximums in DO typical of may water bodies in the Klamath Basin including Tule Lake ( Dileanis et al. 1996). The rise in turbidity at all sites in fall is likely due to the break down of rooted aquatic vegetation which then allows for wind induced wave action to stir the sediments. Other than the DH, all other sites had dense concentrations of rooted aquatic plants and/ or filamentous green algae during summer. June to September DO and pH dynamics in the DH appeared different than at NDH sites ( Figs. 20 and 22). The difference was greatest in early summer with the difference becoming smaller by late summer and essentially disappearing by fall. Whether this water quality difference was a result of the more turbid waters or inflow from springs is unknown. However, attempts by Service hydrologists to model inflows, evapotranspiration, and outflows from the sumps have resulted in a positive imbalance of approximately 21,000 acre- feet of water from April through September. This positive imbalance is greatest in spring and early summer, gradually lessening by summer and essentially disappearing by fall ( Tim Mayer, pers. comm.). If this inflow is occurring, it may explain differences in summer water quality between DH and NDH sites. June to September water quality in the DH may be critical to the over summer survival of suckers in Tule Lake as pH and DO in NDH sites during summer often exceeded the tolerance limits for the fish. DO and pH levels at DH sites were less variable and did not reach the extremes that were reached in NDH sites. The lowest DO measured during June through September at DH sites were 4.83 mg/ 1 ( DHWEST) and 4.96 mg/ 1 ( DHEAST). DO and pH during summer from this study were similar to values collected by Reclamation in 1992 ( Table 3). Buettner and Scoppettone ( 1990) found juvenile suckers only where DO was above 4.5 mg/ 1. It is currently believed that adult suckers become stressed at DO levels below 4.0 mg/ 1 with mortality occurring at or below 2.0 mg/ 1 ( M. Buettner, pers. comm.). The relatively high over- summer survival of radio- marked suckers, compared to suckers radio- marked in Upper Klamath Lake ( M. Buettner, pers. comm), is further evidence of suitable summer water quality conditions in the DH on Tule Lake. 34 Figure 25. " Donut Hole" in Sump 1( A) of Tule Lake NWR.

( Data from U. S. Bureau of Reclamation) pH levels in the DH generally remained below 10.0 whereas non DH sites frequently exceeded 10.0 ( Fig. 19). Falter and Cech ( 1991) determined a maximum pH tolerance in shortnose suckers of 9.55+ 0.43 under laboratory conditions, levels generally exceeded in June - September at non DH sites and some DH sites in late summer. Buettner and Scoppettone ( 1990) found juvenile fish in Upper Klamath Lake largely at sites with pH < 9.0, as did Simon et al. ( 1996) in 1994. However, in 1995, Simon et al. ( 1996) found that most juvenile fish ( 54%) were captured in areas of higher pH (> 10.0). Laboratory studies indicate significant mortality of larval and juvenile fish at high pH values (> 9.55) ( Falter and Cech 1991) and 9.92- 10.46 ( Bellerud and Saiki 1995). Previous water quality and fish health studies on the refuge determined that water quality conditions were stressful to aquatic life and was resulting in a high ( up to 37%) proportion offish with deformities ( Dileanis et al. 1996), however, studies of sucker ecology in Tule Lake have indicated that individual fish in the lake have a high condition factor and are free of external parasites ( Scoppettone and Buettner 1995). Bennet ( 1994) recognized this apparent inconsistency, stating, A... the observation that Tule Lake suckers are in better physical condition than Upper Klamath Lake suckers indicates that certain areas of the aquatic system may be of particular importance for the recovery of those species. ® In the case of Tule Lake this Acertain area@ is likely the DH.. Suckers in Tule Lake may be in good condition because of their limited population size, the abundant food resources in this lake, and adequate water quality ( in the DH) to survive the summer period. 36 Sucker movements Although, suckers were relatively sedentary during most periods of the year, they exhibited the ability to make long distance moves in relatively short periods of time, particularly during the April spawning period. The northwest corner of Sump 1( A) receives about 90% of the inflow from the Lost River and spring winds on Tule Lake tend to move large quantities of water through the AEnglish Channels back and forth between Sump 1( A) and 1( B). This movement of water at both locations may explain the movement of fish observed in April and May. Suckers may be attracted to both locations when seeking spawning habitat in spring. Recruitment During the April marking period, most captured suckers appeared to be physiologically ready to spawn; however, only one fish moved into the river. Of 10 radio- marked fish monitored by Reclamation in 1993- 95 no fish attempted to run the Lost River. This low proportion offish that attempt to spawn may have one or several causes or a combination, including: 1. Stress of handling and implanting radio- transmitters so close to the spawning season may prevent fish from becoming reproductively active. 2. Under normal conditions, only a small proportion of Tule Lake suckers may attempt to spawn in any particular year. 3. Flow conditions in or at the mouth of the Lost River may be inadequate to draw the fish into the river. 4. A shallow bar (< 0.3 m) of deposited silt exists between the lake and the mouth of the river which may form a physical barrier to the fish. At the present time, a mandated flow of 30 cfs is released below Anderson- Rose Dam to provide spawning habitat at the Dam. Although this flow is intended to provide suitable spawning conditions at the Dam, these flows may be inadequate to entice fish into the river. It is likely that the historic spring flows in the Lost River were many times higher than current regulated flows. However, given that the fish are largely unsuccessful in spawning and risk additional mortality traversing the river, adult survival may be enhanced by remaining in the lake. Scoppettone and Buettner ( 1995) also observed no radio- marked fish from Clear Lake to move into Willow Creek during the spring spawning period. In this case the authors attributed this result to either capture stress or low stream flows during spring. 37 Habitat use Although the DH is relatively shallow relative to other areas of Tule Lake, use of the DH may be mandatory to ensure over- summer survival. Although deeper waters are available to the fish, especially in the northwest corner of Sump 1( A), DO levels, in particular, likely preclude their use. Suckers did not move out of the DH until October when DO levels began to rise with cooler water temperatures. Although, Sump 1( B) contained suitable water depths and water quality conditions in fall, no suckers were located in this area. It is possible that suckers may prefer not to pass through the pipes connecting the Sumps or the proximity and flow from the Lost River in the northwest corner of Sump 1( A) may make this area more attractive as an over- winter habitat area. The relative lack of water depth in the DH as well as other areas of the sumps is becoming of increasing concern because of the loss of water depth through sedimentation. If suckers require a minimum of 3 ft of water, as is current believed ( M. Buettner, pers. comm.), current rates of sedimentation in the sumps threaten the future suitability of Tule Lake for suckers. Based on a comparison of bathymetric surveys conducted by Reclamation in 1958 and again in 1986, sedimentation has been steadily reducing the water holding capacity of both sumps. Between the 1958 and 1986 surveys ( 28 years), Sump 1( A) has lost 22.4% of its water capacity and Sump 1( B) has lost 30.8% of its capacity due to sedimentation. This would indicate a total mean sedimentation of 11.8 inches over this time period ( U. S. Bureau of Reclamation, unpubl. rep). Over the last several years, an attempt has been made to store additional water in Tule Lake during summer by raising water levels above 4034.60 ft. This increase in water elevations ( between 4034.60 and 4034.90 ft) has somewhat mitigated the loss of depth through sedimentation. However, without reinforcing and raising the levees around the sumps, there is a limit as to how high water elevations can rise. At elevation 4035.50 ft., operating regulations require breaching the sumps into overflow areas ( Sump 2 or 3). Although increased summer operating levels may assist the fish, they may also increase the risk of a flood event requiring the breaching of the sumps with potentially negative impacts to the fish.

Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 4 vol. (Quigley, Thomas M., tech. ed.; The Interior Columbia Basin Ecosystem Management Project: Scientific Assessment). The Assessment of Ecosystem Components in the Interior Columbia Basin and Portions of the Klamath and Great Basins provides detailed information about current conditions and trends for the biophysical and social systems within the Basin. This information can be used by land managers to develop broad land management goals and priorities and provides the context for decisions specific to smaller geographic areas. The Assessment area covers about 8 percent of the U.S. land area, 24 percent of the Nations National Forest System lands, 10 percent of the Nations BLM-administered lands, and contains about 1.2 percent of the Nations population. This results in a population density that is less than one-sixth of the U.S. average. The area has experienced recent, rapid population growth and generally has a robust, diverse economy. As compared to historic conditions, the terrestrial, aquatic, forest, and rangeland systems have undergone dramatic changes. Forested landscapes are more susceptible to fire, insect, and disease than under historic conditions. Rangelands are highly susceptible to noxious weed invasion. The disturbance regimes that operate on forest and rangeland have changed substantially, with lethal fires dominating many areas where non-lethal fires were the norm historically. Terrestrial habitats that have experienced the greatest decline include the native grassland, native shrubland, and old forest structures. There are areas within the Assessment area that have higher diversity than others. Aquatic systems are now more fragmented and isolated than historically and the introduction of non-native fish species has complicated current status of native fishes. Core habitat and population centers do remain as building blocks for restoration. Social and economic conditions within the Assessment area vary considerably, depending to a great extent on population, diversity of employment opportunities, and changing demographics. Those counties with the higher population densities and greater diversity of employment opportunities are generally more resilient to economic downturns. This Assessment provides a rich information base, including over 170 mapped themes with associated models and databases, from which future decisions can benefit.

Author: U.S. Fish and Wildlife Service Year: 2003, 2008, 2005 EXECUTIVE SUMMARY FOR THE BULL TROUT RECOVERY PLAN Current Species Status The bull trout (Salvelinus confluentus) in the coterminous United States was listed as threatened on November 1, 1999 (64 FR 58910). Earlier rulemakings had listed distinct population segments of bull trout as threatened in the Columbia River, Klamath River, and Jarbidge River basins (63 FR 31647, 63 FR 42757, 64 FR 17110). Bull trout distribution, abundance, and habitat quality have declined rangewide. Several local extirpations have been documented, beginning in the 1950fs. Bull trout continue to occur the Klamath River, Columbia River, Jarbidge River, St. Mary-Belly River, and Coastal-Puget Sound, in the states of Idaho, Montana, Nevada, Oregon, and Washington. Habitat Requirements and Limiting Factors Bull trout have more specific habitat requirements than most other salmonids. Habitat components that influence bull trout distribution and abundance include water temperature, cover, channel form and stability, substrate for spawning and rearing, and migratory corridors. Bull trout are found in colder streams and require colder water than most other salmonids for incubation, juvenile rearing, and spawning. Spawning and rearing areas are often associated with cold-water springs, groundwater infiltration, and/or the coldest streams in a watershed. Throughout their lives, bull trout require complex forms of cover, including large woody debris, undercut banks, boulders, and pools. Alterations in channel form and reductions in channel stability result in habitat degradation and reduced survival of bull trout eggs and juveniles. Channel alterations may reduce the abundance and quality of side channels, stream margins, and pools, which are areas bull trout frequently inhabit. For spawning and early rearing bull trout require loose, clean gravel relatively free of fine sediments. Because bull trout have a relatively long incubation and development period within spawning gravel (greater than 200 days), transport of bedload in unstable channels may kill young bull trout. Bull trout use migratory corridors to move from spawning and rearing habitats to foraging and overwintering habitats and back. Different habitats provide bull trout with diverse resources, and migratory corridors allow local populations to connect, which may increase the potential for gene flow and support or refounding of populations. Declines in bull trout distribution and abundance are the results of combined effects of the following: habitat degradation and fragmentation, the blockage of migratory corridors, poor water quality, angler harvest and poaching, entrainment (process by which aquatic organisms are pulled through a diversion structure or other device) into diversion channels and dams, and introduced iv normative species. Specific land and water management activities that continue to depress bull trout populations and degrade habitat include dams and other diversion structures, forest management practices, livestock grazing, agriculture, road construction and maintenance, mining, and urban and rural development. Some threats to bull trout are the continuing effects of past land management activities. Organization and Development of the Recovery Plan Because bull trout in the coterminous United States are widely distributed within a large area, the recovery plan is organized into multiple chapters. This introductory chapter (Chapter 1) describes our overall recovery strategy for the species, defines recovery, and identifies recovery actions applicable for all listed bull trout in the coterminous United States. Each successive chapter focuses on bull trout in specific geographic areas (recovery units), and describes conditions, defines recovery criteria, and identifies specific recovery actions for the recovery unit. Recovery Objectives The goal of this recovery plan is to describe the actions needed to achieve the recovery of bull trout, that is, to ensure the long-term persistence of self-sustaining, complex interacting groups (or multiple local populations that may have overlapping spawning and rearing areas) of bull trout distributed across the species' native range. Recovery of bull trout will require reducing threats to the long-term persistence of populations, maintaining multiple interconnected populations of bull trout across the diverse habitats of their native range, and preserving the diversity of bull trout life-history strategies (e.g., resident or migratory forms, emigration age, spawning frequency, local habitat adaptations). To recover bull trout, the following four objectives have been identified: ? Maintain current distribution of bull trout within core areas as described in recovery unit chapters and restore distribution where recommended in recovery unit chapters. ? Maintain stable or increasing trend in abundance of bull trout. ? Restore and maintain suitable habitat conditions for all bull trout life history stages and strategies. ? Conserve genetic diversity and provide opportunity for genetic exchange. ? These objectives apply to bull trout in all recovery units. Additional objectives may be necessary to achieve recovery in some recovery units and will be identified in the respective recovery unit chapters. Recovery Criteria Criteria are established to assess whether recovery objectives are being achieved. Criteria specific to each recovery unit are defined in each recovery unit chapter. Individual chapters may contain criteria for assessing the status of bull trout and alleviation of threats that are unique to one or several recovery units. However, every recovery unit chapter will contain criteria that address the following characteristics: ? The distribution of bull trout in identified and potential local populations in all core areas within the recovery unit. ? The estimated abundance of adult bull trout within core areas in the recovery unit, expressed as either a point estimate or a range of individuals. ? The presence of stable or increasing trends for adult bull trout abundance in the recovery unit. ? The restoration of passage at specific barriers identified as inhibiting recovery. We expect recovery of bull trout to be a dynamic process occurring over time. The recovery objectives are based on our current knowledge and may be refined as more information becomes available. Some local populations of bull trout, and possibly core area populations, may be extirpated even though recovery actions are being implemented. If reestablishment of recently extirpated populations is not feasible or practical, recovery criteria for a given recovery unit will be revised on a case-by-case basis. Meeting the four recovery criteria is not intended to be precluded where localized extirpations of bull trout are offset by sufficiently strong improvements in other areas of a recovery unit in meeting the four recovery objectives. The determination of whether a distinct population segment of bull trout is recovered will rely on an analysis of the overall status of the species, threats to the species, and the adequacy of existing regulatory and conservation mechanisms. For example, it may be possible for the Columbia River Distinct Population Segment, which has 22 recovery units, to be recovered prior to all recovery unit criteria being met in all recovery units. Success in accomplishing the recovery VI criteria will be reviewed and considered for the impacts both within a recovery unit and throughout a distinct population segment. Actions Needed Specific tasks falling within the following seven categories will be necessary to initiate recovery within all recovery units: ? Protect, restore, and maintain suitable habitat conditions for bull trout. ? Prevent and reduce negative effects of normative fishes and other normative taxa on bull trout. ? Establish fisheries management goals and objectives compatible with bull trout recovery and implement practices to achieve goals. ? Characterize, conserve, and monitor genetic diversity and gene flow among local populations of bull trout. ? Conduct research and monitoring to implement and evaluate bull trout recovery activities, consistent with an adaptive management approach using feedback from implemented, site-specific recovery tasks. ? Use all available conservation programs and regulations to protect and conserve bull trout and bull trout habitats. ? Assess the implementation of bull trout recovery by recovery units and revise recovery unit plans based on evaluations. Recovery Priority Number The recovery priority number for bull trout in the coterminous United States is 9C, on a scale of 1 to 18, indicating that (1) taxonomically, these populations are distinct population segments of a species, (2) the five populations are subject to a moderate degree of threat(s), (3) the recovery potential is high, and (4) the degree of potential conflict during recovery is high. vrr Estimated Cost of Recovery The total cost estimate of recovery for bull trout in the coterminous United States is presented in the individual recovery unit chapters. The costs presented in each chapter are attributed to bull trout conservation but other species will also benefit. Date of Recovery Expected time to achieve recovery varies among recovery units because of differences in bull trout status, factors affecting bull trout, implementation and effectiveness of recovery tasks, and responses to recovery tasks. Achieving bull trout recovery in all recovery units will be a complex process that will likely take 25 years or more. vin Title: Bull Trout, Salvelinus Confluentus...

Craig Year: 2001, 2008, 2005 1 Acknowledgements 2 3 The completion of this work in large part can be attributed to the efforts of the 4 U.S. Fish and Wildlife Service Arcata Field Office staff and in particular to Mr. 5 Thomas Shaw for providing much of the supporting site-specific field data, 6 habitat mapping, and fisheries data used in the analyses. The efforts of the 7 various Tribal fisheries personnel were critical in supplying additional fisheries 8 collection data, and intensive site substrate and cover mapping. In particular, the 9 efforts of Tim Hayden, Charlie Chamberlain and Mike Belchik. USGS personnel 10 from the Midcontinent Ecological Science Center also provided valuable 11 assistance and field data used in the cross section based hydraulic and habitat 12 modeling. Mr. Gary Smith and Mike Rode of the California Department of Fish 13 and Game also provided critical information on site-specific habitat suitability 14 criteria and conceptual foundations for the escape cover analysis used in the 15 habitat simulations. Much of this work was also supported by work of Tim 16 Harden (Harden and Associates). The Bureau of Reclamation also provided 17 valuable input during the Phase II study process on Klamath Project operations. 18 A special thanks is also given to Mr. Mike Deas (U.C. Davis) for providing water 19 temperature simulations below Iron Gate Dam. The Technical Team also 20 provided critical input and review of all technical elements of this work as well as 21 providing reviews of the report. Finally, the completion of this work would not 22 have been possible without the tireless efforts of Jennifer Ludlow, Mark 23 Winkelaar, James Shoemaker, Shannon Clemens, Jerilyn Brunson, William 24 Bradford, Sarah Blake, Brandy Blank, Matt Combes, Leon Basdekas, and Aaron 25 Hardy at the Institute for Natural Systems Engineering, Utah State University. 26 27 Executive Summary 28 29 Previous instream flow recommendations developed as part of Phase I (Hardy, 30 1999) recommended interim instream flows in the main stem Klamath River 31 based on analyses of hydrology data. At that time, site-specific data suitable for 32 analysis and evaluation using habitat based modeling were not available. This 33 report details the analytical approach and modeling results from site-specific 34 studies conducted within the main stem Klamath River below Iron Gate Dam 35 downstream to the estuary. Study results are utilized to make revised interim 36 instream flow recommendations necessary to protect the aquatic resources 37 within the main stem Klamath River between Iron Gate and the estuary. This 38 report also makes specific recommendations for future research needs as part of 39 the on-going strategic instream flow studies being undertaken by the U.S. Fish 40 and Wildlife Service and collaborating private, local, state, federal, and tribal 41 entities. 42 43 This report was developed for the Department of the Interior (DOI) who provided 44 access to a technical review team composed of representatives of the U.S. Fish 45 and Wildlife Service, Bureau of Reclamation, Bureau of Indian Affairs, U.S. 46 Geological Survey, and the National Marine Fisheries Service. The technical Draft - Subject to Change 1 review team also included participation by the Yurok, Hoopa Valley, and Karuk 2 Tribes given the Departments trust responsibilities and the California Department 3 of Fish and Game as the state level resource management agency. The 4 technical review team provided invaluable assistance in the review of methods 5 and results used in the analysis, provided comments on draft sections of the 6 report, and provided data and supporting material for use in completion of the 7 Phase II report. In addition, several agencies and private individuals provided 8 written comments on the Preliminary Draft Report, which have been addressed in 9 this report where appropriate. 10 11 This report is organized to follow the general process used to implement the 12 technical studies. It first provides important background information on the 13 historical and current conditions of the anadromous species, highlights factors 14 that have contributed to their decline, provides an overview of the Phase I study 15 process and its principal findings. The report then continues with a description of 16 the Phase II technical study process. Key sections address methods and 17 findings for each technical component such as study design, study site selection, 18 field methods, analytical approaches, summary results, and recommended 19 instream flows. 20 21 The Phase II study relied on state-of-the-art field data collection methodologies 22 and modeling of physical habitat for target species and life stages of anadromous 23 fish. The field methods were directed toward achieving a three-dimensional 24 representation of each study site that incorporated between 0.6 to over one mile 25 of river depending on the specific study site. At each study site, a spatially 26 explicit substrate and vegetation map was developed and then integrated with 27 the three-dimensional channel topography in GIS. Fieldwork also involved 28 collection of hydraulic calibration data and fish observation data. The later 29 information was used in the development of habitat suitability criteria, conceptual 30 habitat model development and implementation, and habitat model validation 31 efforts. 32 33 Hydrology in the main stem Klamath River below Iron Gate Dam was estimated 34 differently for different purposes in Phase II. For example, we used simulated 35 unimpaired inflows (i.e., no depletions) to Upper Klamath Lake routed to Iron 36 Gate Dam with no Klamath Project imposed water demands. This simulated 37 scenario represents the best available estimates of the unimpaired flows below 38 Iron Gate Dam for the purposes of this study. The remaining flow scenarios 39 included the use of Upper Klamath Lake net inflows, historical Klamath Project 40 water demands, and the USFWS Biological Opinion (2000) target Upper Klamath 41 Lake water elevations. These scenarios represent different potential operational 42 flow scenarios as points of reference to the instream flow recommendations 43 developed as part of Phase II. Differences between these simulated flow 44 scenarios required the use of different models and/or modeling assumptions. 45 The assumptions and modeling tools are described in the appropriate technical 46 sections of the report. The estimated hydrology at each study site was used in Draft - Subject to Change 1 both the physical habitat modeling and temperature simulations using the USGS 2 Systems Impact Assessment Model (SIAM) or its components. 3 4 Physical habitat modeling at each study site relied on two-dimensional hydraulic 5 simulations that were coupled to three-dimensional habitat models. The 6 analytical form of the habitat models varied for spawning, fry, and 'juveniles' (i.e., 7 pre-smolts). These modeling results were compared to available 1-dimensional 8 cross section based hydraulic and habitat modeling at study sites that overlapped 9 between existing USFWS/USGS and Phase II studies. 10 11 Habitat suitability criteria for target species and life stages of anadromous fish 12 were developed from site-specific data for Chinook spawning, Chinook fry, and 13 steelhead 1+. These curves were validated both by field observations using the 14 habitat modeling results as well as by comparison to results from an individual 15 based bioenergetics model for drift feeding salmonids developed at USU. A 16 separate procedure was developed to obtain habitat suitability curves for Chinook 17 juvenile (i.e., pre-smolts), steelhead fry, and coho fry based on available 18 literature data. This approach used a systematic process to construct an 19 'envelope' habitat suitability curve that encompassed the available literature 20 curves. The overall process included a validation component that compared the 21 habitat versus discharge relationships between envelope curves to the site- 22 specific curves for Chinook spawning, Chinook fry, and steelhead 1+. The results 23 validated the use of the envelope curves for use as interim criteria pending 24 further research and development of site-specific curves for these species and 25 life stages within the Klamath River. 26 27 Habitat modeling involved the integration of substrate and cover mapping with 28 the three-dimensional topography and hydraulic properties at each study site with 29 the habitat suitability curves. Habitat modeling was undertaken for Chinook 30 spawning, fry, and juveniles, coho fry and juveniles, and steelhead fry and 31 steelhead 1+. Different habitat models were developed for spawning, fry, and 32 juveniles. The study generated a salmonid fry habitat model that incorporated a 33 distance to escape cover that also required sufficient depth within the escape 34 cover in order for it to be utilized at a given flow rate. This model also 35 incorporated quantitative differences in the type of escape cover. 36 37 The habitat modeling results for each species and life stage were validated 38 against the spatial distribution of each species and life stage surveyed at study 39 sites at different flow rates. These results generally demonstrated that the 40 integrated habitat modeling was validated for the study in terms of spawning and 41 fry life stages. Our assessment of the pre-smolt or juvenile life stage results is 42 that they are consistent for the existing habitat model assumptions. However, we 43 discuss what we perceive to be inherent biases in these results (juveniles) based 44 on the existing habitat model structure and make specific recommendations of 45 what additional work would likely improve the results for this particular life stage. 46 Draft - Subject to Change jjj 1 Temperature simulations based on the unimpaired flow regime below Iron Gate 2 Dam were conducted with HEC5Q as part of the SIAM applications. These 3 results supported the findings in Phase I that flows lower than ~ 1000 cfs during 4 the late summer would likely increase the environmental risk to anadromous 5 species due to almost continual exposure to chronic temperature thresholds. We 6 believe that these simulation results show that there is very little flexibility for 7 reservoir operations at Iron Gate Dam to mitigate deleterious flow dependent 8 temperature effects. This finding has previously been reported by the USGS 9 (Bartholow 1995) and Deas (1999). 10 11 The integration of the habitat modeling with the unimpaired hydrology was used 12 to develop habitat reference values for target species and life stages at each 13 study reach on a monthly basis for flow exceedence ranges between 10 and 90 14 percent. The reference habitat value was computed as the percent of maximum 15 habitat associated with the unimpaired flow values for each species and life 16 stage on a monthly basis. This reference habitat value was used as one 'target' 17 condition to guide the selection of monthly flow recommendations at a given 18 exceedence flow level. 19 20 The flow recommendation process also employed a prioritization of species and 21 life stages to be considered within the year and/or within a specific month. The 22 prioritization of life stages was taken from the life history sequence of 23 anadromous species (i.e., spawning, fry, and then juveniles). The initial priority 24 order for species was defined as Chinook, then coho, and finally steelhead. It is 25 stressed that this initial prioritization was used to conceptually simplify the flow 26 recommendation process only, and that all species and life stages were 27 examined as part of the overall analysis. The process then relied on an iterative 28 procedure to select target flows for each month at a given exceedence level. 29 This procedure attempted to pick a target flow that would simultaneously 30 preserve the underlying characteristics of the seasonal unimpaired hydrograph at 31 that exceedence flow, the underlying relationship of the unimpaired hydrograph 32 between all exceedence flow levels, while striving to maximize habitat for the 33 priority species and life stages relative to the unimpaired habitat reference 34 conditions. The corresponding monthly flow rates at each exceedence level 35 were then used to compute the percent of maximum habitat for all other species 36 and life stages in a given month. These values were then compared to their 37 respective unimpaired habitat values to ensure that adequate protection of 38 habitat for non-priority species and life stages remained reasonable. 39 40 The flow recommendations developed in the Iron Gate to Shasta River Reach 41 were 'propagated' downstream to each successive reach by addition of the reach 42 gains as presently defined by the USGS in their MODSIM module of SIAM. It is 43 recognized that these reach gains reflect existing depletions in tributary systems 44 (e.g., Shasta and Scott Rivers) but are the only estimates presently available for 45 use in the simulation models for the system. The flow recommendations for each 46 river reach were then used to compute the percent of maximum habitat on a Draft - Subject to Change 1 monthly basis for each species and life stage. The recommended flow based 2 calculation of percent of maximum habitat for each species and life stage was 3 then compared against the associated unimpaired flow based habitat values. 4 5 Although flow recommendations were developed for the 10 to 90 percent 6 exceedence range (i.e., nine water year types), five water year types were 7 identified representing Critically Dry, Dry, Average, Wet, and Extremely Wet 8 inflow conditions for Upper Klamath Lake. These water year classifications 9 parallel those developed for the Trinity River and were used as operational 10 definitions in the Phase I report. Furthermore, the USBR KPSIM model was 11 modified to use this five-water year type format for simulating operations under 12 different instream flow requirements below Iron Gate Dam. The 90, 70, 50, 30, 13 and 10 percent exceedence flow levels were assigned to each of these water 14 year types, respectively (i.e., critically dry to extremely wet). This assignment 15 was used to demonstrate several key points regarding the use of 16 recommendations at this level of resolution (i.e., five water year types) and how 17 the existing operational models for the Klamath Project simulate flow scenarios. 18 19 These five water year type dependent recommendations were utilized in the U.S. 20 Bureau of Reclamation's Klamath Project Simulation Module (KPSIM) to simulate 21 project operations over the 1961 to 1997 period of record. This analysis 22 confirmed that the project could be operated to achieve these recommendations 23 in all but 19 of the 468 simulated months in this period of record. These results 24 also highlighted that an alternative water year 'classification' strategy for 25 specifying instream flows should be considered in lieu of a five water year type 26 scheme. We provide a specific recommendation of how this could be 27 approached based on the instream flow recommendations developed in Phase II. 28 29 30 Draft - Subject to Change Title: Evaluation of Interim Instream Flow Needs in the Klamath River Phase II Final Report Author: Hardy, Thomas B; Addley. R. Craig Year: 2001, 2008, 2005 1 Acknowledgements 2 3 The completion of this work in large part can be attributed to the efforts of the 4 U.S. Fish and Wildlife Service Arcata Field Office staff and in particular to Mr. 5 Thomas Shaw for providing much of the supporting site-specific field data, 6 habitat mapping, and fisheries data used in the analyses. The efforts of the 7 various Tribal fisheries personnel were critical in supplying additional fisheries 8 collection data, and intensive site substrate and cover mapping. In particular, the 9 efforts of Tim Hayden, Charlie Chamberlain and Mike Belchik. USGS personnel 10 from the Midcontinent Ecological Science Center also provided valuable 11 assistance and field data used in the cross section based hydraulic and habitat 12 modeling. Mr. Gary Smith and Mike Rode of the California Department of Fish 13 and Game also provided critical information on site-specific habitat suitability 14 criteria and conceptual foundations for the escape cover analysis used in the 15 habitat simulations. Much of this work was also supported by work of Tim 16 Harden (Harden and Associates). The Bureau of Reclamation also provided 17 valuable input during the Phase II study process on Klamath Project operations. 18 A special thanks is also given to Mr. Mike Deas (U.C. Davis) for providing water 19 temperature simulations below Iron Gate Dam. The Technical Team also 20 provided critical input and review of all technical elements of this work as well as 21 providing reviews of the report. Finally, the completion of this work would not 22 have been possible without the tireless efforts of Jennifer Ludlow, Mark 23 Winkelaar, James Shoemaker, Shannon Clemens, Jerilyn Brunson, William 24 Bradford, Sarah Blake, Brandy Blank, Matt Combes, Leon Basdekas, and Aaron 25 Hardy at the Institute for Natural Systems Engineering, Utah State University. 26 27 Executive Summary 28 29 Previous instream flow recommendations developed as part of Phase I (Hardy, 30 1999) recommended interim instream flows in the main stem Klamath River 31 based on analyses of hydrology data. At that time, site-specific data suitable for 32 analysis and evaluation using habitat based modeling were not available. This 33 report details the analytical approach and modeling results from site-specific 34 studies conducted within the main stem Klamath River below Iron Gate Dam 35 downstream to the estuary. Study results are utilized to make revised interim 36 instream flow recommendations necessary to protect the aquatic resources 37 within the main stem Klamath River between Iron Gate and the estuary. This 38 report also makes specific recommendations for future research needs as part of 39 the on-going strategic instream flow studies being undertaken by the U.S. Fish 40 and Wildlife Service and collaborating private, local, state, federal, and tribal 41 entities. 42 43 This report was developed for the Department of the Interior (DOI) who provided 44 access to a technical review team composed of representatives of the U.S. Fish 45 and Wildlife Service, Bureau of Reclamation, Bureau of Indian Affairs, U.S. 46 Geological Survey, and the National Marine Fisheries Service. The technical Draft - Subject to Change 1 review team also included participation by the Yurok, Hoopa Valley, and Karuk 2 Tribes given the Departments trust responsibilities and the California Department 3 of Fish and Game as the state level resource management agency. The 4 technical review team provided invaluable assistance in the review of methods 5 and results used in the analysis, provided comments on draft sections of the 6 report, and provided data and supporting material for use in completion of the 7 Phase II report. In addition, several agencies and private individuals provided 8 written comments on the Preliminary Draft Report, which have been addressed in 9 this report where appropriate. 10 11 This report is organized to follow the general process used to implement the 12 technical studies. It first provides important background information on the 13 historical and current conditions of the anadromous species, highlights factors 14 that have contributed to their decline, provides an overview of the Phase I study 15 process and its principal findings. The report then continues with a description of 16 the Phase II technical study process. Key sections address methods and 17 findings for each technical component such as study design, study site selection, 18 field methods, analytical approaches, summary results, and recommended 19 instream flows. 20 21 The Phase II study relied on state-of-the-art field data collection methodologies 22 and modeling of physical habitat for target species and life stages of anadromous 23 fish. The field methods were directed toward achieving a three-dimensional 24 representation of each study site that incorporated between 0.6 to over one mile 25 of river depending on the specific study site. At each study site, a spatially 26 explicit substrate and vegetation map was developed and then integrated with 27 the three-dimensional channel topography in GIS. Fieldwork also involved 28 collection of hydraulic calibration data and fish observation data. The later 29 information was used in the development of habitat suitability criteria, conceptual 30 habitat model development and implementation, and habitat model validation 31 efforts. 32 33 Hydrology in the main stem Klamath River below Iron Gate Dam was estimated 34 differently for different purposes in Phase II. For example, we used simulated 35 unimpaired inflows (i.e., no depletions) to Upper Klamath Lake routed to Iron 36 Gate Dam with no Klamath Project imposed water demands. This simulated 37 scenario represents the best available estimates of the unimpaired flows below 38 Iron Gate Dam for the purposes of this study. The remaining flow scenarios 39 included the use of Upper Klamath Lake net inflows, historical Klamath Project 40 water demands, and the USFWS Biological Opinion (2000) target Upper Klamath 41 Lake water elevations. These scenarios represent different potential operational 42 flow scenarios as points of reference to the instream flow recommendations 43 developed as part of Phase II. Differences between these simulated flow 44 scenarios required the use of different models and/or modeling assumptions. 45 The assumptions and modeling tools are described in the appropriate technical 46 sections of the report. The estimated hydrology at each study site was used in Draft - Subject to Change 1 both the physical habitat modeling and temperature simulations using the USGS 2 Systems Impact Assessment Model (SIAM) or its components. 3 4 Physical habitat modeling at each study site relied on two-dimensional hydraulic 5 simulations that were coupled to three-dimensional habitat models. The 6 analytical form of the habitat models varied for spawning, fry, and 'juveniles' (i.e., 7 pre-smolts). These modeling results were compared to available 1-dimensional 8 cross section based hydraulic and habitat modeling at study sites that overlapped 9 between existing USFWS/USGS and Phase II studies. 10 11 Habitat suitability criteria for target species and life stages of anadromous fish 12 were developed from site-specific data for Chinook spawning, Chinook fry, and 13 steelhead 1+. These curves were validated both by field observations using the 14 habitat modeling results as well as by comparison to results from an individual 15 based bioenergetics model for drift feeding salmonids developed at USU. A 16 separate procedure was developed to obtain habitat suitability curves for Chinook 17 juvenile (i.e., pre-smolts), steelhead fry, and coho fry based on available 18 literature data. This approach used a systematic process to construct an 19 'envelope' habitat suitability curve that encompassed the available literature 20 curves. The overall process included a validation component that compared the 21 habitat versus discharge relationships between envelope curves to the site- 22 specific curves for Chinook spawning, Chinook fry, and steelhead 1+. The results 23 validated the use of the envelope curves for use as interim criteria pending 24 further research and development of site-specific curves for these species and 25 life stages within the Klamath River. 26 27 Habitat modeling involved the integration of substrate and cover mapping with 28 the three-dimensional topography and hydraulic properties at each study site with 29 the habitat suitability curves. Habitat modeling was undertaken for Chinook 30 spawning, fry, and juveniles, coho fry and juveniles, and steelhead fry and 31 steelhead 1+. Different habitat models were developed for spawning, fry, and 32 juveniles. The study generated a salmonid fry habitat model that incorporated a 33 distance to escape cover that also required sufficient depth within the escape 34 cover in order for it to be utilized at a given flow rate. This model also 35 incorporated quantitative differences in the type of escape cover. 36 37 The habitat modeling results for each species and life stage were validated 38 against the spatial distribution of each species and life stage surveyed at study 39 sites at different flow rates. These results generally demonstrated that the 40 integrated habitat modeling was validated for the study in terms of spawning and 41 fry life stages. Our assessment of the pre-smolt or juvenile life stage results is 42 that they are consistent for the existing habitat model assumptions. However, we 43 discuss what we perceive to be inherent biases in these results (juveniles) based 44 on the existing habitat model structure and make specific recommendations of 45 what additional work would likely improve the results for this particular life stage. 46 Draft - Subject to Change jjj 1 Temperature simulations based on the unimpaired flow regime below Iron Gate 2 Dam were conducted with HEC5Q as part of the SIAM applications.

Furthermore, the USBR KPSIM model was 11 modified to use this five-water year type format for simulating operations under 12 different instream flow requirements below Iron Gate Dam.

Irrigation and other agricultural practices in the U. S. Bureau of Reclamation's Klamath Project may result in impaired surface water quality, reducing its use for wildlife and fish in important national wildlife refuges that receive drainage water from farms, and in the Klamath River. By 2004, a system of total maximum daily loads (TMDL) for nutrients must be established for the Klamath River. To investigate the relationships among agricultural practices and surface water quality in the Upper Klamath Basin, a two year reconnaissance survey of surface water and agricultural tile drain locations, focusing on nitrogen and phosphorus concentrations and mass transfers was conducted. Data was collected at 18 surface locations and 10 tile drain locations. Triplicate samples were taken every ten days during the growing season (April through October) and one or two times a month during the remainder of the months, depending on opportunity. No samples were taken from tile drains during the winter months because there was no irrigation and drainage during that period. Water samples were analyzed for phosphorus (total P, soluble reactive P, total filterable P, and particulate P) and nitrogen (total N, soluble N, Soluble organic N, total filterable N, particulate N, and ammonia N), temperature, pH and electrical conductivity, a measure of salinity or total dissolved solids. Analyses of data, including data quality, estimates of the transfer of nutrients in surface waters in the region, and hypotheses about the relationship between agriculture and water quality are reported. 1. The salt and nutrient content of surface waters increases nearly threefold as water moves through the watershed from the Lost River and J canal diversion to the Klamath Straits Drain. Mean ECW levels in input waters at the J canal diversion were approximately 250 \iS cm1, while water sampled at the D pump increased to 600 ^S cm"1 on average over the sample period. By the time water reenters the Klamath River, salt concentrations have increased to approximately 700 jaS cm1. 2. The ECW values observed in subsurface tile drains were higher on average than in input waters and surface waters elsewhere in the region, especially in the Lease Lands area of the Tulelake Irrigation District (TID). ECW values averaged approximately 2,500 ^S cm"1 . Recycling irrigation water through soils in the TID increases the salinity of the water, especially by the time it reaches and is reused in the Lease Lands area of the Tulelake National Wildlife Refuge (TLNWR). Soils in this part of the Klamath Project area are naturally high in salt. 3. Water temperatures in agricultural subsurface tile drains were significantly lower than surface water temperatures during the growing season when tile drains were active. pH values in tile drains were lower than surface water values. The temperature and pH of tile drains does not influence surface water values. 1. 4. For total phosphorus (TP) input waters at the J canal irrigation diversion for the TED averaged approximately 0.27 mg L1 for the two years reported. Water leaving the Tulelake Sumps at the D pump increases to 0.33 mg L1. Water leaving the Lower Klamath National Wildlife Refuge (LKNWR) sampled at the start of the Klamath Straits Drain, averaged 0.33 mg L1, similar to those at the D pump. TP increased further to 0.40 mg L"1 a the end of the Klamath Straits Drain. The overall increase in P concentration in surface waters was much less than for salt, suggesting that processes other than simple enrichment are occurring, particularly those associated with the exchange of sedimentary P and aquatic plant species. TN increases from 2.3 mg L"1 to 4.0 mg L1 over the same pathway. Atomic ratios (TN:TP) of surface water samples remain constant at approximately 10:1 throughout the system, suggesting that the amount of sediment and other small particulate matter in surface waters affects the values observed. The amount of sediment is influenced in part by the agitation of surface water as it passes through pumps and over weirs. 5. The average seasonal TP value in tile drains beneath farm fields is approximately 0.34 mg L"1 . While average total P values in subsurface tile drains were not different from those found at the D pump and the LKNWR outlet, the range in values was great (0.1 to 0.8 mg L1). Similarly, high NO3 -N values were observed at times in tile drains. Very high values in tile drains lead to the inference that some fertilizer N and P is lost in drainage water, combined with nutrients derived from decaying soil organic matter. The amount estimated as lost is much less than the amount of surplus fertilizer P applied and the amount of P surmised to be mineralized from decaying soil organic matter. P from fertilizer and decaying organic matter appears to be accumulating in soils and lake sediments in the region. 6. Ammonia N concentrations are at or below the limit of detection in subsurface agricultural tile lines and one to two orders of magnitude below the values observed in surface soils. Un ionized ammonia increases with temperature. Values above 0.25 mg L1 were observed in late summer at several locations. 7. Some leaching of soluble salts and nutrients is unavoidable when crops are irrigated. P fertilizer is applied at rates higher than crop removal, while fertilizer n is applied at rates less than crop removal. Reduced fertilizer use can help bring P inputs and outputs into balance and may reduce further any avoidable losses of P. This objective should be the subject of an agronomic research program in the region. 8. Surface waters entering the TDD, the TLNWR, and the LKNWR are already enriched with N and P. It seems unlikely that reducing N and P losses from farming in the TID, if possible, would influence surface water quality sufficiently to make them significantly less eutrophic. For P, the hypothesized threshold concentration limiting algae growth in fresh waters is 5 to 25 times smaller than the values observed in waters entering the TID for irrigation use. The addition of 1. nutrients from agriculture probably does not influence significantly surface water quality in the region. Wetland sediments, large amounts of organic matter in soils, and water introduced for irrigation contain essentially unlimited amounts of nutrients for aquatic plant growth. It is not clear how this circumstance could be changed under any reasonable time frame, if ever. 9. Using a TMDL approach may not result in reduced amounts of nutrients returned to the Klamath River because wetlands and farming practices in the southern portion of the Klamath Project result in the net removal of nutrients from the waters diverted for irrigation on a yearly basis, compared to allowing the same amount of water simply to flow down the river unused. Because of large errors of estimation for the amounts of water transferred, combined with smaller errors associated with estimating nutrient concentrations in water samples, and with year to year climate variation, TMDLs may not be an effective or efficient means of reducing nutrients in return flows to the Klamath River. Rational confidence limits for TMDLs may have to be too broad to be effective. Recycling of some drainage water for irrigation would reduce the amount of nutrients returned to the river more effectively than implementing a TMDL program. Title: Farming practices and water quality in the Upper Klamath Basin : final report to the California State Water Resources Control Board : 205j program Author: Danosky, Earl; Kaffka, Stephen Year: 2002, 2007, 2006 Summary The Upper Klamath Basin (UKB) is a high desert region straddling the California-Oregon border east of the Cascade Range. Irrigation and other agricultural practices in the U. S. Bureau of Reclamation's Klamath Project may result in impaired surface water quality, reducing its use for wildlife and fish in important national wildlife refuges that receive drainage water from farms, and in the Klamath River. By 2004, a system of total maximum daily loads (TMDL) for nutrients must be established for the Klamath River. To investigate the relationships among agricultural practices and surface water quality in the Upper Klamath Basin, a two year reconnaissance survey of surface water and agricultural tile drain locations, focusing on nitrogen and phosphorus concentrations and mass transfers was conducted. Data was collected at 18 surface locations and 10 tile drain locations. Triplicate samples were taken every ten days during the growing season (April through October) and one or two times a month during the remainder of the months, depending on opportunity. No samples were taken from tile drains during the winter months because there was no irrigation and drainage during that period. Water samples were analyzed for phosphorus (total P, soluble reactive P, total filterable P, and particulate P) and nitrogen (total N, soluble N, Soluble organic N, total filterable N, particulate N, and ammonia N), temperature, pH and electrical conductivity, a measure of salinity or total dissolved solids. Analyses of data, including data quality, estimates of the transfer of nutrients in surface waters in the region, and hypotheses about the relationship between agriculture and water quality are reported. 1. The salt and nutrient content of surface waters increases nearly threefold as water moves through the watershed from the Lost River and J canal diversion to the Klamath Straits Drain. Mean ECW levels in input waters at the J canal diversion were approximately 250 \iS cm1, while water sampled at the D pump increased to 600 ^S cm"1 on average over the sample period.

Natural Resources Conservation Service Year: 2004, 2005 1 i California Oregon Cover Photo: Lower Klamath National Wildlife Refuge at sunset Tupper Ansel Blake/ USFWS Map Detail Area: Upper Klamath River Basin ii T he Klamath River Basin presents numerous challenges as well as opportunities for its many water users. For years, farmers and ranchers in the basin have recognized the vital role they play in the health of their watershed. Working with conservation districts, the Natural Resources Conservation Service ( NRCS) and others, land managers continue to proactively find ways to enhance natural resources in the basin, benefiting wildlife and the environment. However, as it has across the western United States, drought hit home in the Klamath for those who depend on every drop of water to sustain their livelihood, culture and community. In the spring of 2001, the combination of drought and the impact of the Endangered Species Act triggered a shutdown of irrigation water during the growing season, drying up water resources to more than 2,000 farms and ranches. NRCS, in cooperation with local conservation districts, provided a quick infusion of technical assistance and $ 2 million in cost- share funding for cover crops through the Emergency Watershed Protection Program. As cover crops took hold, the seeds of a long- term solution took root in the NRCS/ conservation district partnership. The ability of the local office to receive funding, engage community members and other partners, plan resource improvements, implement actions, and monitor success proved to be an invaluable asset for the community. Helping private landowners develop and apply practical, common- sense solutions to complex resource issues will be the challenge of the conservation partnership well into the future. USDA, in concert with the locally led conservation districts, will continue to play a critical role by delivering technical and financial assistance to Klamath Basin farmers and ranchers. The Rapid Subbasin Assessments that follow are the first step in that process. The assessments are designed to help local decision- makers determine where investments in conservation will best benefit wildlife habitat, agriculture and other land uses in a compatible manner. It is our goal to provide a comprehensive overview of resource challenges and opportunities in the basin, and help decision- makers to prioritize their investments in areas that will best sustain multiple use of natural resources in the basin now and in the future.

Stretching across southern Oregon and northern California, the Klamath Basin has become synonymous with the water challenges that western water users face. As one example, agricultural commodities that need irrigation water to thrive – providing Americans with the cheapest domestic food supply in the world, face competition from the critical water needs of sucker fish, salmon and other threatened and endangered species. While that competition is understandable, more and more, conservation leaders in all industries have come to recognize that these water needs aren’t necessarily at odds with one another, and can in fact be compatible. While an example of the challenges today’s agricultural producers and conservationists face, the Klamath Basin has emerged as an example of how diverse interests can work together successfully. 2 Overview of the Upper Klamath Basin Upper Klamath Basin Description The Upper Klamath Basin is an area of high desert, wetlands, and the Klamath River. The river extends 250 miles from its headwaters at Upper Klamath Lake in south central Oregon to the west coast of northern California. The Upper Klamath Basin includes the US Bureau of Reclamation’s ( USBR) Klamath Project Area and the drainage area above Irongate Dam on the Klamath River. The basin’s lakes, marshes, and wetlands host an abundance of plant and animal species and include national wildlife refuges, parks, and forests. Agricultural production began around the turn of the 20th century, and with the creation of the Klamath Irrigation District in 1905, water diversions for irrigation began in earnest. A portion of these irrigated lands are in the USBR’s irrigation project. The ‘ project area,’ as it is commonly called, includes 188,000 of the 502,000 acres of private irrigated land in the basin. This includes lands leased from the various wildlife refuges that are supplied with water by the USBR. Privately irrigated acreages can vary from year to year, depending on USBR contracts and annual cropping cycles. In comparison, the majority of the private irrigated land - about 314,000 acres - in the basin is located outside the project area. Upper Klamath Basin Quick Facts: • Over 2.2 million acres are privately owned in the Upper Klamath Basin • 188,000 of the irrigated acres are in the US Bureau of Reclamation’s Irrigation Project • Approximately 502,000 acres of privately owned lands are irrigated • 314,000 acres of irrigated lands are outside the Project area 3 Overview of the Upper Klamath Basin The Role of Agriculture in the Basin Agricultural lands play a key role in a healthy ecosystem. Located on the Pacific Flyway, migratory birds like the American White Pelican and the Red- Necked Grebe use croplands in the Klamath Basin as an important feeding and resting stop. Deer graze on wheat and barley fields, and pheasants use both crop and rangelands for their nesting and feeding grounds. Progressive conservation leaders recognize that farming and fish and wildlife habitat are not mutually exclusive. Well- maintained farmland creates fish and wildlife habitat, contributing to a healthy watershed. They also recognize that opportunities will always exist to improve the condition of natural resources in the basin. To address those opportunities, conservation leaders in Oregon’s Klamath Falls Soil and Water Conservation District and California’s Lava Beds/ Butte Valley Resource Conservation District have proactively identified four key priorities tied to natural resource conservation. The districts asked experts at the USDA’s Natural Resources Conservation Service to help them develop a plan to determine what could be done on- farm to conserve water, increase water storage, improve water quality, and enhance fish and wildlife habitat. While so much of the attention to date in the Klamath Basin has been focused on water demand, these conservation leaders recognize demand is only one piece of the puzzle. Comprehensive solutions must also address water quality, storage and wildlife habitat. Conservation District Priorities 1) Conserve Water 2) Increase Water Storage 3) Improve Water Quality 4) Enhance Fish & Wildlife Habitat 4 Rapid Subbasin Assessments Conserving natural resources is the ultimate goal throughout the basin, and its success hinges on long- term solutions. At the request of local conservation districts, NRCS undertook an 18- month study of resource concerns, challenges and opportunities throughout the Upper Klamath Basin. The study was not intended to provide a detailed, quantitative analysis of the impacts of conservation work, but rather, to provide an initial estimate of where conservation investments would best address the districts’ four priority resource concerns. Beginning in the spring of 2002, NRCS planners collected information to enable the conservation districts, agencies, organizations, farmers, ranchers and others to make informed decisions in a timely manner about conservation and resource management in the basin. These Rapid Subbasin Assessments are intended to help leaders set priorities and determine the best actions to achieve their goals. As a part of the rapid subbasin assessment process, eight subbasins were delineated ( see map at left). A watershed planning team traveled through each subbasin, inventorying agricultural areas, identifying conservation opportunities and current levels of resource management, and estimating the impacts of these opportunities on the Conservation in the Upper Klamath Basin 5 Conservation in the Upper Klamath Basin conservation districts’ priority resource concerns. They focused their recommendations on areas that would provide the best benefit to the wide array of stakeholders in the Upper Klamath Basin. They also identified a number of socio- economic factors that must be taken into consideration when helping producers adapt to new management styles and conservation activities. Through NRCS, conservation districts and other federal, state and local entities, private land managers are working to identify ways they can more efficiently use – and share – the water they need. In the face of increasingly complex and politically polarized circumstances, a clear purpose and direction has arisen. The commitment of the local conservation partnership to identify the impacts of water shortages and to find solutions that will improve natural resource conservation will be key to the long- term viability of both endangered species and industries in the Upper Klamath Basin. The information that follows provides a summary of the conservation challenges and opportunities that NRCS staff found in their assessment. Recommendations for where financial and other resources can best be invested to improve natural resources, while sustaining the economy of the Upper Klamath Basin, are also identified. 6 Conservation in the Upper Klamath Basin Private Lands Conservation Accomplishments One component necessary to understanding future conservation opportunities in the basin is to recognize the current conservation work of private land managers. An indicator of these efforts is the work that has been undertaken in partnership with NRCS and the local conservation districts. In federal fiscal years 2002 and 2003, Upper Klamath Basin farmers and ranchers improved resource conditions on 18,877 acres of privately owned agricultural lands, with assistance from NRCS and the conservation districts. During this time, private land managers have worked with the conservation districts in the basin to: • improve the condition of 11,800 acres of grazing lands • conserve water and improve water quality on 13,656 acres • restore and establish 4,138 acres of wetlands and riparian areas • improve 281 acres of forest stands • establish resource management systems on 1,351 acres of cropland These conservation efforts were accomplished with a combination of private, state and federal funding. 7 Conservation in the Upper Klamath Basin Summary of Conservation Opportunities In addition to recognizing current conservation activities, the assessments define what can be accomplished with a strong conservation partnership in the Upper Klamath Basin. All too often, the debate about multi- use of water in the basin has focused on ways to reduce water demand. However, the basin’s many water users - including fish and wildlife - benefit just as much from improvements to water quality, water storage and wildlife habitat. Taken together, the recommendations that follow seek to utilize a comprehensive approach to all four resource priorities - with the goal of contributing to a sustainable, multi- use water system. While quantification of the results of conservation work in these four areas is difficult, there is no question that a comprehensive approach to natural resource improvement in the Upper Klamath Basin will result in accumulative long- term benefits for endangered fish species, wildlife habitat, agriculture, urban and other water uses. Agriculture cannot undertake these efforts alone. Private landowners and the general public both benefit from natural resources conservation in the Upper Klamath Basin. Because of this, public and private sources of funding from in and outside the region are necessary. Solutions of this magnitude also come with other social, political, and cultural costs. Upper Klamath Basin Quick Facts: • 1,400 farm families live in the Upper Klamath Basin • The Upper Klamath Basin is home to sucker fish, bull trout and redband trout 8 Conservation in the Upper Klamath Basin For example, all stakeholders in the Upper Klamath Basin need to identify and address social, economic, and cultural resource- based values they have historically enjoyed. Politically, there must be resolution and agreement on water rights, endangered species, and water quality. Water Conservation Because few water use measurements have been taken in the past, it is difficult to quantify where specific water efficiencies can be gained. Throughout the Upper Klamath Basin, water that leaves one irrigated field generally re- enters streams or enters the groundwater, providing the opportunity for it to be utilized again later. Because of this, water delivery systems both in and outside the USBR project area are generally efficient. As a result, the most significant benefit of reducing water demand on individual farms is an improvement in water quality and reduction in water temperatures, rather than an increase in available water. 9 Conservation in the Upper Klamath Basin Conservation measures that reduce water demand on private agricultural lands can be accomplished in a variety of ways. New technologies for managing when and where water is applied on crop and pasture lands will help to ensure that water is only applied when it is of the best benefit to the plant. Water conservation opportunities include improving irrigation water-use efficiency, retaining and conserving drainage water, and making use of new technologies that more accurately forecast the impacts of drought and floods. The subbasin assessments indicate an opportunity to conserve water and improve water quality on 130,000 acres of irrigated lands within the USBR project. Outside the project area there is an opportunity for water conservation on approximately 220,000 irrigated acres. If all potential conservation practices are implemented on all irrigated lands, on- farm water use efficiency could increase by up to 25 percent in the Upper Klamath Basin. A potential two to five percent increase in water yield could be achieved by increasing management in upland range and forestland areas. In all cases, these are preliminary estimates and require validation. This estimate does not account for evaporation, transpiration, seepage or other loses that may occur at the sites receiving conserved water nor does it evaluate irrigation delivery or conveyance efficiencies. Tupper Ansel Blake/ USFWS 10 Conservation in the Upper Klamath Basin This level of water conservation cannot be reached without a concerted federal/ state/ private partnership that works together to apply water conservation practices in targeted areas throughout the Upper Klamath Basin. Improving Water Quality Water quality has a direct impact on many fish and wildlife species. Within the Upper Klamath Basin, most rivers and lakes do not meet federally mandated Clean Water Act standards for temperature, dissolved oxygen, pH, or other pollutants. Water quality is affected by water temperature, low in- stream flows and the condition of adjacent land riparian areas, among other items. Private landowners are just one of many groups who have an opportunity to improve water quality throughout the basin. Water quality improvement opportunities on private agricultural lands in the basin range from improving the management of livestock near streams and rivers to utilizing new technologies that track pest and weed cycles to ensure that pesticides are only applied when they will be most effective. Water conservation practices that reduce tailwater runoff from irrigated fields can provide extensive improvements in water quality. 11 Conservation in the Upper Klamath Basin Increasing Water Storage/ Yield In recent years, drought has been a large contributing factor to reduced water levels in the Upper Klamath Basin. One solution to address low water flows would be to store water for times of water shortage. There are at least two challenges to this solution: finding a place to store water and finding water to store. To evaluate this option, potential storage values were calculated for 41 years of record from 1961 to 2002. This analysis reinforced the observation that, as has been seen in recent years, drought years normally occur in a multi- year cycle. Because of this, in the years where extra water is most needed, it is often not available from previous years to store. One promising, small- scale, water storage solution may lie in subsurface irrigation water storage in suitable locations, such as the Tulelake Subbasin. In this scenario, there exists a potential to store water in the soil profile and reduce irrigation water demand during the irrigation season. Another option for subsurface storage of water includes the restoration of streams and their surrounding wetlands and riparian areas. This can increase the “ sponge” effect allowing for the slow release of water through the long, dry summer months. Tupper Ansel Blake/ USFWS 12 Conservation in the Upper Klamath Basin Enhancing Fish and Wildlife Habitat The Upper Klamath Basin is home to a wide variety of aquatic and terrestrial species of wildlife and fish. Much of the water used in the Klamath wildlife refuges and associated marshes, ponds, streams and wetlands originates in the Upper Klamath Lake Subbasin. The Klamath Basin wildlife refuges provide a stopover for 85 percent of the ducks, geese, and other birds that migrate through the Pacific Flyway from Alaska to South America. Streams in the Upper Klamath Basin provide spawning and rearing habitat to threatened and endangered suckers and bull trout, as well as redband trout, which is listed as a species of concern by the US Fish and Wildlife Service. Several streams are highly valued “ catch and release” sport fisheries. There is high landowner and public interest in restoring and maintaining riparian habitat along these streams. Many of the conservation opportunities outlined under water conservation and water quality provide direct benefits to fish and wildlife as well. In addition, creating and restoring wetland areas, planting trees and developing wildlife habitat along the edges of crop fields all contribute to enhancing wildlife habitat in the basin. Tupper Ansel Blake/ USFWS 13 Conservation in the Upper Klamath Basin Overview of Conservation Effectiveness In order for the Upper Klamath Basin to successfully move forward with solutions, agriculturists, environmentalists, Tribes, government agencies, organizations, and others need to develop unified leadership to arrive at a common vision for the future. In addition, stakeholders and others must commit to a long- term investment of public and private funding as well as other resources. Based on the Upper Klamath Basin Rapid Subbasin Assessments, the Oregon and California NRCS planning staff rated the potential benefit of recommended conservation practices and resource management systems based on the conservation districts’ four resource priorities. Many state and federal agencies have invested in conservation work throughout the basin. While the recommendations in this document focus on private land and agriculture, the assessments can also be applied to help prioritize conservation practices on other land uses basin- wide. Overall, based on the planning team’s analysis, conservation activities in the Sprague River Subbasin would produce the greatest benefit, and conservation practices in the Upper Klamath River East Subbasin would yield the least Tupper Ansel Blake/ USFWS overall benefit based on the conservation district’s priorities. 14 Conservation in the Upper Klamath Basin While recognizing that any science- based conservation focus in the Upper Klamath Basin would be beneficial, the charts on pages 18- 19 specifically focus on work that can be accomplished on private lands. They provide a breakdown of recommended conservation practices on each of the conservation districts’ priorities by subbasin. For example, the water demand chart shows that investing in conservation practices in the Sprague River Subbasin has the greatest potential for reducing agriculture’s water demand by implementing improved irrigation practices. The Sprague also provides the best opportunity to address water quality and wildlife habitat. Investment in conservation activities in the Tulelake and the Upper Klamath Lake subbasins offers the greatest potential to address water storage/ yield. Investing in Conservation: Enabling farmers, ranchers and other private land managers to successfully address the four resource priorities will require: • The adoption of conservation on 350,000 acres of private farmland, range, and forests, • Financial resources estimated at $ 200 million for installation and another $ 27 million annually to operate, and • Twenty or more years to complete with the current financial and technical resources available.

In comparison, the Tulelake Subbasin gains water yield through agronomic practices like subsurface drains to allow for winter irrigation. Overall, implementing forest and range practices in most subbasins will result in greater water yield within the soil profile and water table. Comparative Benefit: Habitat/ Fish Survival The chart at right provides an overview of the comparative benefit by subbasin of various conservation practices that improve wildlife habitat and fish survival. Based on research completed by NRCS planning staff, the greatest potential to improve habitat is in the Sprague Subbasin, using wetland/ riparian, forest, range and irrigation practices. In comparison, no measurable habitat benefits are achieved by implementing additional conservation practices in the Middle Lost River, Tulelake, Butte Valley or Upper Klamath River subbasins. Conservation in the Upper Klamath Basin 17 Tim McCabe/ NRCS 18 The Sprague River Subbasin is located 25 miles northeast of Klamath Falls and covers approximately 1.02 million acres. Forested mountain ridges enclose the Sprague River Valley, which includes large marshes, meadows and irrigated pasture. Juniper and sagebrush steppes dominate rangeland. Irrigated Pasture is the predominant land use in the Sprague River Valley. Approximately 65 percent of the water used for irrigation is diverted from streams, and 35 percent is pumped from wells. Flooding is the most common form of irrigation. Most diversions do not have fish screens and lack devices to measure water deliveries. Overall irrigation application efficiencies are low. Private forest and rangelands in the Sprague River subbasin are generally used for livestock grazing. Most forest stands are significantly overstocked with trees, and rangeland has been heavily encroached by Western Juniper. Pasture condition is generally poor to fair. The riparian areas within pastures have little to no riparian vegetation and high, eroding banks. Wildlife habitat in most of the upper reaches of the Sprague River and its major tributaries appears to be fairly stable, indicating good watershed condition. However, there are considerable habitat improvements that can be made in the lower portion of the basin. Sprague River Subbasin Water & Wetlands: 2,949 Range: 137,869 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 240,050 Sprague River Subbasin Agricultural Land Use/ Cover 19 Resource Concerns Water quality is the major resource concern in the Sprague River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. Lost River and shortnose suckers, interior redband and bull trout are key fish species present in the subbasin. All species are listed as Endangered Species Act threatened, candidate, or species of concern. The Sprague River has been identified as an important stream for both spawning and rearing habitat for suckers. Loss of riparian habitat, fish entrapment and fish migration impediments have also been identified as resource concerns in the Sprague River Subbasin. Conservation Accomplishments In the Sprague River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved the condition of 2,153 acres of grazing land, improved irrigation water management on 903 acres of irrigated land, and have restored 1,644 acres of riparian and wetlands areas. Fencing and riparian area restoration has been initiated or installed by private land managers with assistance from NRCS, US Fish & Wildlife Service and others on approximately 50 miles of stream and several thousand additional riparian and wetland acres.

Riparian pasture units should be managed as a part of an overall grazing plan with cross- fencing and off- stream water for livestock. Forest stands should be managed to ensure optimum health of both the trees and grazed understory. Thinning overstocked trees and controlling juniper on rangelands are both effective management opportunities. Water Demand: Irrigation water management, including measuring water use and scheduling irrigation will help managers to maintain base river flows through late summer and early fall. Efficiencies can also be gained by leveling land, lining or piping irrigation ditches and incorporating tailwater recovery systems. Conversion from flood to sprinkler irrigation is also beneficial.

Combined, the Williamson and Sprague River subbasins make up 79 percent of the lake’s total drainage area. The Winema National Forest and Klamath Falls National Wildlife Refuge account for most of the public land in the subbasin. Irrigated pasture is the dominant private agricultural land use. Pasture is almost entirely flood irrigated. Ninety percent is diverted from streams, while groundwater supplies ten percent. Most diversions do not have fish screens and lack devices to measure water deliveries. Although overall irrigation application efficiency is low, additional water in the water table helps to subirrigate pastures. In addition, the proximity of these pastures to rivers and streams allows most excess diverted water to return to the system for reuse. Private forest and rangelands make up most of the private land in the basin. Approximately 80 percent of forestlands are used for grazing. Private forestland is in poor to fair condition; over half of the stands are significantly overstocked with trees. Wildlife habitat has faced considerable degradation in the past. Of the 48 miles of stream that are degraded in the subbasin, restoration efforts have been initiated on approximately 23 miles. Williamson River Subbasin Water & Wetlands: 19,700 Range: 2,600 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 225,300 Williamson River Subbasin Agricultural Land Use/ Cover Irrigated Alfalfa: 1,100 23 Water quality relating to elevated stream temperatures is a major resource concern in the Williamson River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. In 1988, when the Lost River and Shortnose suckers were listed as endangered, the Williamson and Sprague River runs were estimated to have declined by as much as 95 percent during the previous twenty- year period. Important sucker habitat has diminished by nearly 50 percent in the lower reaches and near the mouth of the Williamson River. This has reduced the amount of larval sucker spawning and rearing habitat. Conservation Accomplishments Significant conservation progress has been made in this subbasin. Land managers have improved 500 acres of grazing lands, 1,000 acres of irrigated lands, 235 acres of forestlands and have restored 112 acres of riparian and wetland areas. Heightened landowner awareness of resource concerns and increasing agency, organization, and individual efforts will help this trend to continue. Of the 48 miles of stream that are degraded in the subbasin, private land managers are working with the US Fish and Wildlife Service and others to restore 23 miles. The Nature Conservancy is restoring approximately 3,200 acres of wetlands, and plans to restore another 3,411 acres at the mouth of the Williamson River.

This can be accomplished by converting lands from irrigated agriculture to wildlife habitat or creating riparian pasture systems. Wetland and riparian areas still utilize water. However, this work may reduce total water demand depending on how lands are managed. Water Demand: Thinning forest stands and managing grazing areas by adding cross fences and off- stream water for livestock can yield more water to meet downstream needs. This will also result in enhanced wildlife habitat and improved water quality in area streams. In addition, forest stand improvements reduce the potential for catastrophic fire.

Historically, some 43,000 acres of wetlands surrounded Agency and Upper Klamath Lake. Today, 17,000 acres have been preserved as part of the Upper Klamath Lake National Wildlife Refuge. Another 11,000 acres have been acquired for restoration. Irrigated agriculture is primarily pasture. Livestock are generally stocker cattle, who graze between April and November. Pasture condition is generally fair. Most livestock obtain water from streams and ditches. Irrigation water is diverted from streams or pumped from the lake. Most diversions do not have fish screens or devices to measure water. Although overall irrigation application efficiency is low, the additional water raises the water table and subirrigated pastures. Some acreages of hay and cereal crops are grown, and irrigation efficiencies are higher than for pasture. However, most require maintenance and re- leveling. Forestlands are primarily pine and mixed fir and hemlock. Most private lands in the subbasin are forest or rangelands, with approximately 80 percent used for grazing. More than half of the forest stands are significantly overstocked with trees. Wildlife habitat varies in condition. Of 70 total miles, 21 miles of streamside riparian areas are in good condition and another 12 miles are being restored.

The loss of wetland vegetation around the lake has also been linked to lower survival rates for endangered suckers. The lower reaches of the Wood River and Sevenmile Creek provide some rearing habitat for larval and juvenile suckers. The Wood River, Sevenmile Creek and their tributaries support populations of bull and interior redband trout. A highly valued “ catch and release” sport fishery occurs on the Wood River and several of its tributaries. There is significant interest in enhancing riparian habitat along these streams to protect and promote these fisheries. Conservation Accomplishments In the Upper Klamath Lake Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved 12 acres of grazing lands and improved water quality and quantity on 12 acres of irrigated land. Several thousand more acres of wetland restoration are in the process of being planned or implemented around Upper Klamath Lake.

This can be accomplished by either converting pastures to permanent wildlife habitat or by creating riparian pastures. While most pastures are being inefficiently irrigated, conditions do not warrant extensive changes from current flood irrigation systems since water is reused or enters the soil profile Water Storage: In the Upper Klamath Lake Subbasin, the potential for non- traditional water storage presents a unique conservation opportunity. Restoring drained wetlands, still farmed around Upper Klamath Lake, could produce positive benefits for all four resource concerns. By actively managing areas for both seasonal wetlands and farming, water can be both filtered to improve water quality and stored in wetland areas for future use.

The valley once supported a vast network of wet meadows and marshes. This subbasin covers approximately 1.2 million acres and is split from the Middle Lost River Subbasin near Olene. Irrigated agriculture generally occurs in the warmer valleys. Flood is the most common pasture irrigation method, with about 50 percent of the water coming from the USBR project. Pasture condition is fair, and most pastures have not been renovated or re- leveled for some time. Maintenance would increase the efficiencies of 60 to 80 percent of the systems. Alfalfa is customarily sprinkler- irrigated and well- managed. Although irrigation efficiencies are higher than for pasture, many sprinkler systems still need upgrading. Several irrigated crops are grown in the subbasin including cereal grains, potatoes, and strawberry plants. Forestland, range and pasture are grazed by livestock. Rangelands are comprised of juniper and sagebrush steppes. Forestlands are generally mixed conifer. Livestock operations include cow/ calf, stockers and dairies. Confined livestock operations are located throughout the subbasin. The location and duration of confinement may pose a potential risk to water quality. Seven dairies located within the subbasin have existing liquid and dry livestock waste storage facilities.

High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving over the last 10 to 20 years. While agriculture is the dominant land use in this subbasin, other sources of phosphorus and other pollutants exist. Sewage treatment outfalls, on- site sewage disposal systems, wildlife, and natural inputs also contribute nutrients and other pollutants to the system. While historically the river had significant fish runs, it currently supports only a small population of Shortnose and Lost River suckers. Conservation Accomplishments In the Upper Lost River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved resource conditions on 234 acres of croplands and 5,282 acres of grazing lands, and have improved their management of irrigation water on 5,596 acres of irrigated lands. In addition, 846 acres of riparian and wetland areas have been restored.

On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops. Implementing practices like diverting clean water before it flows through livestock confinement areas near water sources, will reduce the risk of polluted runoff. Water Demand: On both surface-irrigated pastures and cropland areas, there are opportunities for land leveling or smoothing, lining or piping irrigation delivery ditches, upgrading irrigation systems and developing tailwater recovery systems to improve water use efficiency.

Farms near Klamath Falls tend to be smaller, indicating part- time or hobby operations. The area includes 12 irrigation districts and leased lands on the Lower Klamath Wildlife Refuge that receive water supplied by the USBR Klamath Project. Public lands include the refuge, and parts of Modoc and Klamath national forests. Irrigated agriculture includes pasture, alfalfa, cereal grain, potatoes, onions and mint. Roughly 70 percent is irrigated with USBR- supplied water; the rest is obtained from groundwater, individual surface water rights or special USBR contracts. Many fields are either flood or sprinkler irrigated depending on the year and crop. Most farm irrigation diversions lack a means to measure water delivery. Livestock operations include several dairies and cattle feeding operations. Substantial range acreage is used for livestock grazing. Pasture condition is fair and most pastures have not been renovated or re- leveled for some time. Pastures associated with smaller livestock operations in and around Klamath Falls appear to be in the most need of improved pastures and irrigation systems. Wildlife habitat: Ten river miles are in relatively good riparian condition given the river is used for conveying irrigation water. Some 13 miles of stream lack adequate riparian vegetation and streambank protection.

Drought conditions and increased competition for available water have increased economic, social, political and environmental concerns and uncertainty over the future. Habitat and water quality are two additional major resource concerns in the subbasin. High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other pollutant sources exist. While the river had significant historic fish runs, it currently supports only a small sucker population. Conservation Accomplishments In the last two years, the Middle Lost River Subbasin has seen significant conservation progress. With assistance from NRCS and local conservation districts, land managers have improved the condition of natural resources on 489 acres of cropland and 3,521 grazing land acres. In addition, 564 acres of riparian and wetland areas have been restored, and water use efficiency has been increased on 3,731 acres of irrigated lands.

Highly effective conservation measures on hay and cropland should focus on updating existing irrigation systems and improving irrigation water management. Water Quality: The use of grazing systems that rotate livestock through smaller pastures will increase forage production, reduce soil compaction and improve water quality. While fishery benefits from restoring riparian areas are minimal, streamside buffers will improve water quality and provide habitat for other wildlife. On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops.

Tulelake is a remnant of historic Lake Modoc that once connected the subbasin with both Lower and Upper Klamath Lake. The Lost River watershed was once a closed basin. Runoff flowed into Tulelake and evaporated. Pumping plants and drains constructed as a part of the project have provided an outlet from Tulelake, which now functions as an open basin. Irrigated agriculture is generally supplied by the USBR. Alfalfa, grain, potatoes, onions, mint and pasture are the principal crops. Fields are flood or sprinkler irrigated depending on the year and crop. Often diversions lack devices to measure water delivery. Pasture condition is fair, and most have not been renovated for some time. Groundwater provides 40- 50 percent of water for irrigated pastures, and most excess water is reused. Rangeland is the other significant land use. Most ranches are cow/ calf operations that have winter holdings in the subbasin. Rangelands are generally encroached with juniper. Wildlife habitat along the Lost River has reeds and bullrush, providing some habitat for waterfowl and songbirds. Suckers have been located in the river and Tulelake; however, it is not known whether they are successfully reproducing. There are few opportunities to improve habitat along this heavily manipulated reach of the river.

Irrigators depend on water- use decisions made by fellow irrigators and resource managers for their irrigation needs. Drought and increased competition for water leads to the primary resource concern in the basin - a reliable supply of water to meet agriculture, wildlife and other resource needs. Water quality deteriorates as it moves through the USBR project. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other sources of phosphorus and other pollutants exist. The presence of ESA- listed suckers creates concerns for improving habitat and water quality. The two national wildlife refuges support large waterfowl populations. Farmland on the refuges is leased to farmers to supply grain for waterfowl and shorebirds. These populations depend on refuges, leased lands and adjacent farms during the fall and spring migratory periods. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds. Conservation Accomplishments In the Tulelake Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, local land managers have improved the condition of natural resources on 72 cropland acres and 1,854 irrigated land acres, and have restored 21 acres of riparian and wetland areas.

Subsurface drainage could be added before re- establishing alfalfa stands, permitting better control of water table and soil moisture levels. During years that alfalfa fields are rotated to grain, winter flooding or pre- season irrigation could be used to reduce water demand. Water Storage/ Yield: Adding subsurface drainage may be the most significant practice to implement on cropland acres. Subsurface drains would allow farmers to winter flood or pre-irrigate fields, thereby reducing their demand for water during the irrigation season. If pre- irrigated, farmers could grow a cereal crop even if water deliveries are cut off during drought years. In addition, juniper control on rangelands will yield additional water to meet downstream needs.

While part of the Upper Klamath Basin, it is an internal drainage basin with only an artificial outlet. Groundwater flows from west to east out of the subbasin under the Mahogany Mountains toward the lake. A channel and pump plant were built to remove floodwaters. This channel is used infrequently and for only short durations. The Klamath National Forest, Butte Valley National Grassland, and the Butte Valley Wildlife Area make up the majority of the public lands. Irrigated agriculture includes alfalfa hay as the predominate crop. Cereal grains, potatoes and strawberry plants are also grown. Crops are usually sprinkler irrigated, and sprinklers are well maintained. Few irrigators measure water applied or schedule irrigation. Cattle operations graze irrigated pastures and meadows scattered throughout the subbasin along with range and forestlands. Pastures are generally flood irrigated and are supplied by streams. Most farm irrigation diversions lack water measuring devices. Mixed conifer forests are found at higher elevations and are generally operated as industrial forests. Range sites are dominated by Western Juniper and are generally in poor condition. Wildlife habitat is generally wetlands in the state wildlife refuge or on national grasslands. Approximately 26 miles of streams on private lands have inadequate riparian vegetation.

Generally, streams in the upper portions of the subbasin support good populations of Brown and Rainbow trout. The Tulelake National Wildlife Refuge and Lower Klamath Lake National Wildlife Refuge support large populations of migratory and permanent waterfowl. Farmland on the refuges is leased to area farmers to supply grain for the waterfowl and shorebirds. The large bird populations depend on the refuges, leased lands and adjacent farms throughout the fall and spring migratory periods for habitat. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds. Conservation Accomplishments In the Butte Valley Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, local land managers have restored 27 acres of riparian and wetland areas in the last two years.

Other than limited contributions to groundwater in the Upper Klamath Basin, reductions in water demand only benefit the subbasin. Sprinkler- irrigated hay, cereal crops and row crops dominate land use on the better soils. Highly effective conservation on hay and cropland should focus on improving the overall irrigation efficiency of existing systems. This can be accomplished by upgrading systems and scheduling irrigation. An estimated 40 percent of the existing systems would benefit from maintenance. On controlled flood irrigated pastures, there are opportunities for land leveling or smoothing, lining or piping delivery ditches, and recovering tailwater. Additional water savings and water quality benefits could be gained by converting existing surface irrigation to sprinklers if power is available and affordable. On rangelands, juniper control and improved grazing management are the primary conservation opportunities.

Nearly half of the area is in public ownership. Iron Gate and Copco reservoirs are used extensively for recreational fishing, boating and camping. Whitewater rafting and kayaking are popular below the KC Boyle Dam. The KC Boyle, Copco and Iron Gate dams are used and regulated for power generation. Irrigated agriculture occurs on only 4,000 acres of pasture. Only a few isolated ranches are located in this subbasin. Cattle operations rotate grazing of irrigated pastures with significant acreage of grazed range and forest. Pastures are surface irrigated with a mix of controlled and flood irrigation. All irrigation water is diverted from the river or tributary streams. Most farm irrigation diversions lack devices to measure water. Even though overall irrigation application efficiency is low, the proximity of irrigated pastures to the river allows most excess water diverted to be reused downstream. Private forest and rangelands make up most of the private land, nearly all of which is used for livestock grazing. Much of the rangeland is in poor condition, with heavy juniper encroachment. More than half of the forest stands are overstocked with trees. Wildlife habitat along riparian areas is generally in good condition. Of the 12 miles of riparian areas surveyed, five would benefit from some restoration.

Water withdrawals are insignificant along this stretch of the river. Salmon and steelhead are blocked at Iron Gate Dam from upstream passage. Several resident trout species exist, supporting a recreational fishery. Conservation Accomplishments In the Klamath River East Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved the condition of natural resources on 56 acres of cropland, 332 acres of grazing land, and 560 acres of irrigated lands. They have also improved forestland health on 46 acres and have restored 924 acres of riparian and wetland areas.

Natural Resources Conservation Service Year: 2004, 2005 1 i California Oregon Cover Photo: Lower Klamath National Wildlife Refuge at sunset Tupper Ansel Blake/ USFWS Map Detail Area: Upper Klamath River Basin ii T he Klamath River Basin presents numerous challenges as well as opportunities for its many water users. For years, farmers and ranchers in the basin have recognized the vital role they play in the health of their watershed. Working with conservation districts, the Natural Resources Conservation Service ( NRCS) and others, land managers continue to proactively find ways to enhance natural resources in the basin, benefiting wildlife and the environment. However, as it has across the western United States, drought hit home in the Klamath for those who depend on every drop of water to sustain their livelihood, culture and community. In the spring of 2001, the combination of drought and the impact of the Endangered Species Act triggered a shutdown of irrigation water during the growing season, drying up water resources to more than 2,000 farms and ranches. NRCS, in cooperation with local conservation districts, provided a quick infusion of technical assistance and $ 2 million in cost- share funding for cover crops through the Emergency Watershed Protection Program. As cover crops took hold, the seeds of a long- term solution took root in the NRCS/ conservation district partnership. The ability of the local office to receive funding, engage community members and other partners, plan resource improvements, implement actions, and monitor success proved to be an invaluable asset for the community. Helping private landowners develop and apply practical, common- sense solutions to complex resource issues will be the challenge of the conservation partnership well into the future. USDA, in concert with the locally led conservation districts, will continue to play a critical role by delivering technical and financial assistance to Klamath Basin farmers and ranchers. The Rapid Subbasin Assessments that follow are the first step in that process. The assessments are designed to help local decision- makers determine where investments in conservation will best benefit wildlife habitat, agriculture and other land uses in a compatible manner. It is our goal to provide a comprehensive overview of resource challenges and opportunities in the basin, and help decision- makers to prioritize their investments in areas that will best sustain multiple use of natural resources in the basin now and in the future.

Stretching across southern Oregon and northern California, the Klamath Basin has become synonymous with the water challenges that western water users face. As one example, agricultural commodities that need irrigation water to thrive – providing Americans with the cheapest domestic food supply in the world, face competition from the critical water needs of sucker fish, salmon and other threatened and endangered species. While that competition is understandable, more and more, conservation leaders in all industries have come to recognize that these water needs aren’t necessarily at odds with one another, and can in fact be compatible. While an example of the challenges today’s agricultural producers and conservationists face, the Klamath Basin has emerged as an example of how diverse interests can work together successfully. 2 Overview of the Upper Klamath Basin Upper Klamath Basin Description The Upper Klamath Basin is an area of high desert, wetlands, and the Klamath River. The river extends 250 miles from its headwaters at Upper Klamath Lake in south central Oregon to the west coast of northern California. The Upper Klamath Basin includes the US Bureau of Reclamation’s ( USBR) Klamath Project Area and the drainage area above Irongate Dam on the Klamath River. The basin’s lakes, marshes, and wetlands host an abundance of plant and animal species and include national wildlife refuges, parks, and forests. Agricultural production began around the turn of the 20th century, and with the creation of the Klamath Irrigation District in 1905, water diversions for irrigation began in earnest. A portion of these irrigated lands are in the USBR’s irrigation project. The ‘ project area,’ as it is commonly called, includes 188,000 of the 502,000 acres of private irrigated land in the basin. This includes lands leased from the various wildlife refuges that are supplied with water by the USBR. Privately irrigated acreages can vary from year to year, depending on USBR contracts and annual cropping cycles. In comparison, the majority of the private irrigated land - about 314,000 acres - in the basin is located outside the project area. Upper Klamath Basin Quick Facts: • Over 2.2 million acres are privately owned in the Upper Klamath Basin • 188,000 of the irrigated acres are in the US Bureau of Reclamation’s Irrigation Project • Approximately 502,000 acres of privately owned lands are irrigated • 314,000 acres of irrigated lands are outside the Project area 3 Overview of the Upper Klamath Basin The Role of Agriculture in the Basin Agricultural lands play a key role in a healthy ecosystem. Located on the Pacific Flyway, migratory birds like the American White Pelican and the Red- Necked Grebe use croplands in the Klamath Basin as an important feeding and resting stop. Deer graze on wheat and barley fields, and pheasants use both crop and rangelands for their nesting and feeding grounds. Progressive conservation leaders recognize that farming and fish and wildlife habitat are not mutually exclusive. Well- maintained farmland creates fish and wildlife habitat, contributing to a healthy watershed. They also recognize that opportunities will always exist to improve the condition of natural resources in the basin. To address those opportunities, conservation leaders in Oregon’s Klamath Falls Soil and Water Conservation District and California’s Lava Beds/ Butte Valley Resource Conservation District have proactively identified four key priorities tied to natural resource conservation. The districts asked experts at the USDA’s Natural Resources Conservation Service to help them develop a plan to determine what could be done on- farm to conserve water, increase water storage, improve water quality, and enhance fish and wildlife habitat. While so much of the attention to date in the Klamath Basin has been focused on water demand, these conservation leaders recognize demand is only one piece of the puzzle. Comprehensive solutions must also address water quality, storage and wildlife habitat. Conservation District Priorities 1) Conserve Water 2) Increase Water Storage 3) Improve Water Quality 4) Enhance Fish & Wildlife Habitat 4 Rapid Subbasin Assessments Conserving natural resources is the ultimate goal throughout the basin, and its success hinges on long- term solutions. At the request of local conservation districts, NRCS undertook an 18- month study of resource concerns, challenges and opportunities throughout the Upper Klamath Basin. The study was not intended to provide a detailed, quantitative analysis of the impacts of conservation work, but rather, to provide an initial estimate of where conservation investments would best address the districts’ four priority resource concerns. Beginning in the spring of 2002, NRCS planners collected information to enable the conservation districts, agencies, organizations, farmers, ranchers and others to make informed decisions in a timely manner about conservation and resource management in the basin. These Rapid Subbasin Assessments are intended to help leaders set priorities and determine the best actions to achieve their goals. As a part of the rapid subbasin assessment process, eight subbasins were delineated ( see map at left). A watershed planning team traveled through each subbasin, inventorying agricultural areas, identifying conservation opportunities and current levels of resource management, and estimating the impacts of these opportunities on the Conservation in the Upper Klamath Basin 5 Conservation in the Upper Klamath Basin conservation districts’ priority resource concerns. They focused their recommendations on areas that would provide the best benefit to the wide array of stakeholders in the Upper Klamath Basin. They also identified a number of socio- economic factors that must be taken into consideration when helping producers adapt to new management styles and conservation activities. Through NRCS, conservation districts and other federal, state and local entities, private land managers are working to identify ways they can more efficiently use – and share – the water they need. In the face of increasingly complex and politically polarized circumstances, a clear purpose and direction has arisen. The commitment of the local conservation partnership to identify the impacts of water shortages and to find solutions that will improve natural resource conservation will be key to the long- term viability of both endangered species and industries in the Upper Klamath Basin. The information that follows provides a summary of the conservation challenges and opportunities that NRCS staff found in their assessment. Recommendations for where financial and other resources can best be invested to improve natural resources, while sustaining the economy of the Upper Klamath Basin, are also identified. 6 Conservation in the Upper Klamath Basin Private Lands Conservation Accomplishments One component necessary to understanding future conservation opportunities in the basin is to recognize the current conservation work of private land managers. An indicator of these efforts is the work that has been undertaken in partnership with NRCS and the local conservation districts. In federal fiscal years 2002 and 2003, Upper Klamath Basin farmers and ranchers improved resource conditions on 18,877 acres of privately owned agricultural lands, with assistance from NRCS and the conservation districts. During this time, private land managers have worked with the conservation districts in the basin to: • improve the condition of 11,800 acres of grazing lands • conserve water and improve water quality on 13,656 acres • restore and establish 4,138 acres of wetlands and riparian areas • improve 281 acres of forest stands • establish resource management systems on 1,351 acres of cropland These conservation efforts were accomplished with a combination of private, state and federal funding. 7 Conservation in the Upper Klamath Basin Summary of Conservation Opportunities In addition to recognizing current conservation activities, the assessments define what can be accomplished with a strong conservation partnership in the Upper Klamath Basin. All too often, the debate about multi- use of water in the basin has focused on ways to reduce water demand. However, the basin’s many water users - including fish and wildlife - benefit just as much from improvements to water quality, water storage and wildlife habitat. Taken together, the recommendations that follow seek to utilize a comprehensive approach to all four resource priorities - with the goal of contributing to a sustainable, multi- use water system. While quantification of the results of conservation work in these four areas is difficult, there is no question that a comprehensive approach to natural resource improvement in the Upper Klamath Basin will result in accumulative long- term benefits for endangered fish species, wildlife habitat, agriculture, urban and other water uses. Agriculture cannot undertake these efforts alone. Private landowners and the general public both benefit from natural resources conservation in the Upper Klamath Basin. Because of this, public and private sources of funding from in and outside the region are necessary. Solutions of this magnitude also come with other social, political, and cultural costs. Upper Klamath Basin Quick Facts: • 1,400 farm families live in the Upper Klamath Basin • The Upper Klamath Basin is home to sucker fish, bull trout and redband trout 8 Conservation in the Upper Klamath Basin For example, all stakeholders in the Upper Klamath Basin need to identify and address social, economic, and cultural resource- based values they have historically enjoyed. Politically, there must be resolution and agreement on water rights, endangered species, and water quality. Water Conservation Because few water use measurements have been taken in the past, it is difficult to quantify where specific water efficiencies can be gained. Throughout the Upper Klamath Basin, water that leaves one irrigated field generally re- enters streams or enters the groundwater, providing the opportunity for it to be utilized again later. Because of this, water delivery systems both in and outside the USBR project area are generally efficient. As a result, the most significant benefit of reducing water demand on individual farms is an improvement in water quality and reduction in water temperatures, rather than an increase in available water. 9 Conservation in the Upper Klamath Basin Conservation measures that reduce water demand on private agricultural lands can be accomplished in a variety of ways. New technologies for managing when and where water is applied on crop and pasture lands will help to ensure that water is only applied when it is of the best benefit to the plant. Water conservation opportunities include improving irrigation water-use efficiency, retaining and conserving drainage water, and making use of new technologies that more accurately forecast the impacts of drought and floods. The subbasin assessments indicate an opportunity to conserve water and improve water quality on 130,000 acres of irrigated lands within the USBR project. Outside the project area there is an opportunity for water conservation on approximately 220,000 irrigated acres. If all potential conservation practices are implemented on all irrigated lands, on- farm water use efficiency could increase by up to 25 percent in the Upper Klamath Basin. A potential two to five percent increase in water yield could be achieved by increasing management in upland range and forestland areas. In all cases, these are preliminary estimates and require validation. This estimate does not account for evaporation, transpiration, seepage or other loses that may occur at the sites receiving conserved water nor does it evaluate irrigation delivery or conveyance efficiencies. Tupper Ansel Blake/ USFWS 10 Conservation in the Upper Klamath Basin This level of water conservation cannot be reached without a concerted federal/ state/ private partnership that works together to apply water conservation practices in targeted areas throughout the Upper Klamath Basin. Improving Water Quality Water quality has a direct impact on many fish and wildlife species. Within the Upper Klamath Basin, most rivers and lakes do not meet federally mandated Clean Water Act standards for temperature, dissolved oxygen, pH, or other pollutants. Water quality is affected by water temperature, low in- stream flows and the condition of adjacent land riparian areas, among other items. Private landowners are just one of many groups who have an opportunity to improve water quality throughout the basin. Water quality improvement opportunities on private agricultural lands in the basin range from improving the management of livestock near streams and rivers to utilizing new technologies that track pest and weed cycles to ensure that pesticides are only applied when they will be most effective. Water conservation practices that reduce tailwater runoff from irrigated fields can provide extensive improvements in water quality. 11 Conservation in the Upper Klamath Basin Increasing Water Storage/ Yield In recent years, drought has been a large contributing factor to reduced water levels in the Upper Klamath Basin. One solution to address low water flows would be to store water for times of water shortage. There are at least two challenges to this solution: finding a place to store water and finding water to store. To evaluate this option, potential storage values were calculated for 41 years of record from 1961 to 2002. This analysis reinforced the observation that, as has been seen in recent years, drought years normally occur in a multi- year cycle. Because of this, in the years where extra water is most needed, it is often not available from previous years to store. One promising, small- scale, water storage solution may lie in subsurface irrigation water storage in suitable locations, such as the Tulelake Subbasin. In this scenario, there exists a potential to store water in the soil profile and reduce irrigation water demand during the irrigation season. Another option for subsurface storage of water includes the restoration of streams and their surrounding wetlands and riparian areas. This can increase the “ sponge” effect allowing for the slow release of water through the long, dry summer months. Tupper Ansel Blake/ USFWS 12 Conservation in the Upper Klamath Basin Enhancing Fish and Wildlife Habitat The Upper Klamath Basin is home to a wide variety of aquatic and terrestrial species of wildlife and fish. Much of the water used in the Klamath wildlife refuges and associated marshes, ponds, streams and wetlands originates in the Upper Klamath Lake Subbasin. The Klamath Basin wildlife refuges provide a stopover for 85 percent of the ducks, geese, and other birds that migrate through the Pacific Flyway from Alaska to South America. Streams in the Upper Klamath Basin provide spawning and rearing habitat to threatened and endangered suckers and bull trout, as well as redband trout, which is listed as a species of concern by the US Fish and Wildlife Service. Several streams are highly valued “ catch and release” sport fisheries. There is high landowner and public interest in restoring and maintaining riparian habitat along these streams. Many of the conservation opportunities outlined under water conservation and water quality provide direct benefits to fish and wildlife as well. In addition, creating and restoring wetland areas, planting trees and developing wildlife habitat along the edges of crop fields all contribute to enhancing wildlife habitat in the basin. Tupper Ansel Blake/ USFWS 13 Conservation in the Upper Klamath Basin Overview of Conservation Effectiveness In order for the Upper Klamath Basin to successfully move forward with solutions, agriculturists, environmentalists, Tribes, government agencies, organizations, and others need to develop unified leadership to arrive at a common vision for the future. In addition, stakeholders and others must commit to a long- term investment of public and private funding as well as other resources. Based on the Upper Klamath Basin Rapid Subbasin Assessments, the Oregon and California NRCS planning staff rated the potential benefit of recommended conservation practices and resource management systems based on the conservation districts’ four resource priorities. Many state and federal agencies have invested in conservation work throughout the basin. While the recommendations in this document focus on private land and agriculture, the assessments can also be applied to help prioritize conservation practices on other land uses basin- wide. Overall, based on the planning team’s analysis, conservation activities in the Sprague River Subbasin would produce the greatest benefit, and conservation practices in the Upper Klamath River East Subbasin would yield the least Tupper Ansel Blake/ USFWS overall benefit based on the conservation district’s priorities. 14 Conservation in the Upper Klamath Basin While recognizing that any science- based conservation focus in the Upper Klamath Basin would be beneficial, the charts on pages 18- 19 specifically focus on work that can be accomplished on private lands. They provide a breakdown of recommended conservation practices on each of the conservation districts’ priorities by subbasin. For example, the water demand chart shows that investing in conservation practices in the Sprague River Subbasin has the greatest potential for reducing agriculture’s water demand by implementing improved irrigation practices. The Sprague also provides the best opportunity to address water quality and wildlife habitat. Investment in conservation activities in the Tulelake and the Upper Klamath Lake subbasins offers the greatest potential to address water storage/ yield. Investing in Conservation: Enabling farmers, ranchers and other private land managers to successfully address the four resource priorities will require: • The adoption of conservation on 350,000 acres of private farmland, range, and forests, • Financial resources estimated at $ 200 million for installation and another $ 27 million annually to operate, and • Twenty or more years to complete with the current financial and technical resources available.

Based on research completed by NRCS planning staff, the greatest potential to enhance water storage and yield occurs by implementing riparian/ wetland, forest and range conservation practices in the Upper Klamath Lake Subbasin. In comparison, the Tulelake Subbasin gains water yield through agronomic practices like subsurface drains to allow for winter irrigation. Overall, implementing forest and range practices in most subbasins will result in greater water yield within the soil profile and water table. Comparative Benefit: Habitat/ Fish Survival The chart at right provides an overview of the comparative benefit by subbasin of various conservation practices that improve wildlife habitat and fish survival. Based on research completed by NRCS planning staff, the greatest potential to improve habitat is in the Sprague Subbasin, using wetland/ riparian, forest, range and irrigation practices.

Conservation in the Upper Klamath Basin 17 Tim McCabe/ NRCS 18 The Sprague River Subbasin is located 25 miles northeast of Klamath Falls and covers approximately 1.02 million acres. Forested mountain ridges enclose the Sprague River Valley, which includes large marshes, meadows and irrigated pasture. Juniper and sagebrush steppes dominate rangeland. Irrigated Pasture is the predominant land use in the Sprague River Valley. Approximately 65 percent of the water used for irrigation is diverted from streams, and 35 percent is pumped from wells. Flooding is the most common form of irrigation. Most diversions do not have fish screens and lack devices to measure water deliveries. Overall irrigation application efficiencies are low. Private forest and rangelands in the Sprague River subbasin are generally used for livestock grazing. Most forest stands are significantly overstocked with trees, and rangeland has been heavily encroached by Western Juniper. Pasture condition is generally poor to fair. The riparian areas within pastures have little to no riparian vegetation and high, eroding banks. Wildlife habitat in most of the upper reaches of the Sprague River and its major tributaries appears to be fairly stable, indicating good watershed condition. However, there are considerable habitat improvements that can be made in the lower portion of the basin. Sprague River Subbasin Water & Wetlands: 2,949 Range: 137,869 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 240,050 Sprague River Subbasin Agricultural Land Use/ Cover 19 Resource Concerns Water quality is the major resource concern in the Sprague River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. Lost River and shortnose suckers, interior redband and bull trout are key fish species present in the subbasin. All species are listed as Endangered Species Act threatened, candidate, or species of concern. The Sprague River has been identified as an important stream for both spawning and rearing habitat for suckers. Loss of riparian habitat, fish entrapment and fish migration impediments have also been identified as resource concerns in the Sprague River Subbasin. Conservation Accomplishments In the Sprague River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved the condition of 2,153 acres of grazing land, improved irrigation water management on 903 acres of irrigated land, and have restored 1,644 acres of riparian and wetlands areas. Fencing and riparian area restoration has been initiated or installed by private land managers with assistance from NRCS, US Fish & Wildlife Service and others on approximately 50 miles of stream and several thousand additional riparian and wetland acres. Sprague River Subbasin Land Ownership Private Lands 448,200 Public Lands 573,100 Total Land Area: 1,021,300 Irrigated Acres USBR Project: 0 Non- USBR: 61,600 Total: 61,600 20 Conservation Opportunities Water Quality & Wildlife Habitat: Riparian restoration can be accomplished by converting pastures to permanent riparian wildlife lands or establishing riparian vegetation. Riparian pasture units should be managed as a part of an overall grazing plan with cross- fencing and off- stream water for livestock. Forest stands should be managed to ensure optimum health of both the trees and grazed understory. Thinning overstocked trees and controlling juniper on rangelands are both effective management opportunities. Water Demand: Irrigation water management, including measuring water use and scheduling irrigation will help managers to maintain base river flows through late summer and early fall. Efficiencies can also be gained by leveling land, lining or piping irrigation ditches and incorporating tailwater recovery systems. Conversion from flood to sprinkler irrigation is also beneficial.

Combined, the Williamson and Sprague River subbasins make up 79 percent of the lake’s total drainage area. The Winema National Forest and Klamath Falls National Wildlife Refuge account for most of the public land in the subbasin. Irrigated pasture is the dominant private agricultural land use. Pasture is almost entirely flood irrigated. Ninety percent is diverted from streams, while groundwater supplies ten percent. Most diversions do not have fish screens and lack devices to measure water deliveries. Although overall irrigation application efficiency is low, additional water in the water table helps to subirrigate pastures. In addition, the proximity of these pastures to rivers and streams allows most excess diverted water to return to the system for reuse. Private forest and rangelands make up most of the private land in the basin. Approximately 80 percent of forestlands are used for grazing. Private forestland is in poor to fair condition; over half of the stands are significantly overstocked with trees. Wildlife habitat has faced considerable degradation in the past. Of the 48 miles of stream that are degraded in the subbasin, restoration efforts have been initiated on approximately 23 miles. Williamson River Subbasin Water & Wetlands: 19,700 Range: 2,600 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 225,300 Williamson River Subbasin Agricultural Land Use/ Cover Irrigated Alfalfa: 1,100 23 Water quality relating to elevated stream temperatures is a major resource concern in the Williamson River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. In 1988, when the Lost River and Shortnose suckers were listed as endangered, the Williamson and Sprague River runs were estimated to have declined by as much as 95 percent during the previous twenty- year period. Important sucker habitat has diminished by nearly 50 percent in the lower reaches and near the mouth of the Williamson River. This has reduced the amount of larval sucker spawning and rearing habitat. Conservation Accomplishments Significant conservation progress has been made in this subbasin. Land managers have improved 500 acres of grazing lands, 1,000 acres of irrigated lands, 235 acres of forestlands and have restored 112 acres of riparian and wetland areas. Heightened landowner awareness of resource concerns and increasing agency, organization, and individual efforts will help this trend to continue. Of the 48 miles of stream that are degraded in the subbasin, private land managers are working with the US Fish and Wildlife Service and others to restore 23 miles. The Nature Conservancy is restoring approximately 3,200 acres of wetlands, and plans to restore another 3,411 acres at the mouth of the Williamson River.

This can be accomplished by converting lands from irrigated agriculture to wildlife habitat or creating riparian pasture systems. Wetland and riparian areas still utilize water. However, this work may reduce total water demand depending on how lands are managed. Water Demand: Thinning forest stands and managing grazing areas by adding cross fences and off- stream water for livestock can yield more water to meet downstream needs. This will also result in enhanced wildlife habitat and improved water quality in area streams. In addition, forest stand improvements reduce the potential for catastrophic fire.

Historically, some 43,000 acres of wetlands surrounded Agency and Upper Klamath Lake. Today, 17,000 acres have been preserved as part of the Upper Klamath Lake National Wildlife Refuge. Another 11,000 acres have been acquired for restoration. Irrigated agriculture is primarily pasture. Livestock are generally stocker cattle, who graze between April and November. Pasture condition is generally fair. Most livestock obtain water from streams and ditches. Irrigation water is diverted from streams or pumped from the lake. Most diversions do not have fish screens or devices to measure water. Although overall irrigation application efficiency is low, the additional water raises the water table and subirrigated pastures. Some acreages of hay and cereal crops are grown, and irrigation efficiencies are higher than for pasture. However, most require maintenance and re- leveling. Forestlands are primarily pine and mixed fir and hemlock. Most private lands in the subbasin are forest or rangelands, with approximately 80 percent used for grazing. More than half of the forest stands are significantly overstocked with trees. Wildlife habitat varies in condition. Of 70 total miles, 21 miles of streamside riparian areas are in good condition and another 12 miles are being restored.

The loss of wetland vegetation around the lake has also been linked to lower survival rates for endangered suckers. The lower reaches of the Wood River and Sevenmile Creek provide some rearing habitat for larval and juvenile suckers. The Wood River, Sevenmile Creek and their tributaries support populations of bull and interior redband trout. A highly valued “ catch and release” sport fishery occurs on the Wood River and several of its tributaries. There is significant interest in enhancing riparian habitat along these streams to protect and promote these fisheries. Conservation Accomplishments In the Upper Klamath Lake Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved 12 acres of grazing lands and improved water quality and quantity on 12 acres of irrigated land. Several thousand more acres of wetland restoration are in the process of being planned or implemented around Upper Klamath Lake.

This can be accomplished by either converting pastures to permanent wildlife habitat or by creating riparian pastures. While most pastures are being inefficiently irrigated, conditions do not warrant extensive changes from current flood irrigation systems since water is reused or enters the soil profile Water Storage: In the Upper Klamath Lake Subbasin, the potential for non- traditional water storage presents a unique conservation opportunity. Restoring drained wetlands, still farmed around Upper Klamath Lake, could produce positive benefits for all four resource concerns. By actively managing areas for both seasonal wetlands and farming, water can be both filtered to improve water quality and stored in wetland areas for future use.

The valley once supported a vast network of wet meadows and marshes. This subbasin covers approximately 1.2 million acres and is split from the Middle Lost River Subbasin near Olene. Irrigated agriculture generally occurs in the warmer valleys. Flood is the most common pasture irrigation method, with about 50 percent of the water coming from the USBR project. Pasture condition is fair, and most pastures have not been renovated or re- leveled for some time. Maintenance would increase the efficiencies of 60 to 80 percent of the systems. Alfalfa is customarily sprinkler- irrigated and well- managed. Although irrigation efficiencies are higher than for pasture, many sprinkler systems still need upgrading. Several irrigated crops are grown in the subbasin including cereal grains, potatoes, and strawberry plants. Forestland, range and pasture are grazed by livestock. Rangelands are comprised of juniper and sagebrush steppes. Forestlands are generally mixed conifer. Livestock operations include cow/ calf, stockers and dairies. Confined livestock operations are located throughout the subbasin. The location and duration of confinement may pose a potential risk to water quality. Seven dairies located within the subbasin have existing liquid and dry livestock waste storage facilities.

High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving over the last 10 to 20 years. While agriculture is the dominant land use in this subbasin, other sources of phosphorus and other pollutants exist. Sewage treatment outfalls, on- site sewage disposal systems, wildlife, and natural inputs also contribute nutrients and other pollutants to the system. While historically the river had significant fish runs, it currently supports only a small population of Shortnose and Lost River suckers. Conservation Accomplishments In the Upper Lost River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved resource conditions on 234 acres of croplands and 5,282 acres of grazing lands, and have improved their management of irrigation water on 5,596 acres of irrigated lands. In addition, 846 acres of riparian and wetland areas have been restored.

On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops. Implementing practices like diverting clean water before it flows through livestock confinement areas near water sources, will reduce the risk of polluted runoff. Water Demand: On both surface-irrigated pastures and cropland areas, there are opportunities for land leveling or smoothing, lining or piping irrigation delivery ditches, upgrading irrigation systems and developing tailwater recovery systems to improve water use efficiency.

Farms near Klamath Falls tend to be smaller, indicating part- time or hobby operations. The area includes 12 irrigation districts and leased lands on the Lower Klamath Wildlife Refuge that receive water supplied by the USBR Klamath Project. Public lands include the refuge, and parts of Modoc and Klamath national forests. Irrigated agriculture includes pasture, alfalfa, cereal grain, potatoes, onions and mint. Roughly 70 percent is irrigated with USBR- supplied water; the rest is obtained from groundwater, individual surface water rights or special USBR contracts. Many fields are either flood or sprinkler irrigated depending on the year and crop. Most farm irrigation diversions lack a means to measure water delivery. Livestock operations include several dairies and cattle feeding operations. Substantial range acreage is used for livestock grazing. Pasture condition is fair and most pastures have not been renovated or re- leveled for some time. Pastures associated with smaller livestock operations in and around Klamath Falls appear to be in the most need of improved pastures and irrigation systems. Wildlife habitat: Ten river miles are in relatively good riparian condition given the river is used for conveying irrigation water. Some 13 miles of stream lack adequate riparian vegetation and streambank protection.

Drought conditions and increased competition for available water have increased economic, social, political and environmental concerns and uncertainty over the future. Habitat and water quality are two additional major resource concerns in the subbasin. High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other pollutant sources exist. While the river had significant historic fish runs, it currently supports only a small sucker population. Conservation Accomplishments In the last two years, the Middle Lost River Subbasin has seen significant conservation progress. With assistance from NRCS and local conservation districts, land managers have improved the condition of natural resources on 489 acres of cropland and 3,521 grazing land acres. In addition, 564 acres of riparian and wetland areas have been restored, and water use efficiency has been increased on 3,731 acres of irrigated lands.

Highly effective conservation measures on hay and cropland should focus on updating existing irrigation systems and improving irrigation water management. Water Quality: The use of grazing systems that rotate livestock through smaller pastures will increase forage production, reduce soil compaction and improve water quality. While fishery benefits from restoring riparian areas are minimal, streamside buffers will improve water quality and provide habitat for other wildlife. On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops.

The Tulelake Irrigation District and the Tulelake National Wildlife Refuge receive water from the USBR Klamath Project. Tulelake is a remnant of historic Lake Modoc that once connected the subbasin with both Lower and Upper Klamath Lake. The Lost River watershed was once a closed basin. Runoff flowed into Tulelake and evaporated. Pumping plants and drains constructed as a part of the project have provided an outlet from Tulelake, which now functions as an open basin. Irrigated agriculture is generally supplied by the USBR. Alfalfa, grain, potatoes, onions, mint and pasture are the principal crops. Fields are flood or sprinkler irrigated depending on the year and crop. Often diversions lack devices to measure water delivery. Pasture condition is fair, and most have not been renovated for some time. Groundwater provides 40- 50 percent of water for irrigated pastures, and most excess water is reused. Rangeland is the other significant land use. Most ranches are cow/ calf operations that have winter holdings in the subbasin. Rangelands are generally encroached with juniper. Wildlife habitat along the Lost River has reeds and bullrush, providing some habitat for waterfowl and songbirds. Suckers have been located in the river and Tulelake; however, it is not known whether they are successfully reproducing. There are few opportunities to improve habitat along this heavily manipulated reach of the river.

Irrigators depend on water- use decisions made by fellow irrigators and resource managers for their irrigation needs. Drought and increased competition for water leads to the primary resource concern in the basin - a reliable supply of water to meet agriculture, wildlife and other resource needs. Water quality deteriorates as it moves through the USBR project. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other sources of phosphorus and other pollutants exist. The presence of ESA- listed suckers creates concerns for improving habitat and water quality. The two national wildlife refuges support large waterfowl populations. Farmland on the refuges is leased to farmers to supply grain for waterfowl and shorebirds. These populations depend on refuges, leased lands and adjacent farms during the fall and spring migratory periods. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds. Conservation Accomplishments In the Tulelake Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, local land managers have improved the condition of natural resources on 72 cropland acres and 1,854 irrigated land acres, and have restored 21 acres of riparian and wetland areas.

Subsurface drainage could be added before re- establishing alfalfa stands, permitting better control of water table and soil moisture levels. During years that alfalfa fields are rotated to grain, winter flooding or pre- season irrigation could be used to reduce water demand. Water Storage/ Yield: Adding subsurface drainage may be the most significant practice to implement on cropland acres. Subsurface drains would allow farmers to winter flood or pre-irrigate fields, thereby reducing their demand for water during the irrigation season. If pre- irrigated, farmers could grow a cereal crop even if water deliveries are cut off during drought years. In addition, juniper control on rangelands will yield additional water to meet downstream needs.

While part of the Upper Klamath Basin, it is an internal drainage basin with only an artificial outlet. Groundwater flows from west to east out of the subbasin under the Mahogany Mountains toward the lake. A channel and pump plant were built to remove floodwaters. This channel is used infrequently and for only short durations. The Klamath National Forest, Butte Valley National Grassland, and the Butte Valley Wildlife Area make up the majority of the public lands. Irrigated agriculture includes alfalfa hay as the predominate crop. Cereal grains, potatoes and strawberry plants are also grown. Crops are usually sprinkler irrigated, and sprinklers are well maintained. Few irrigators measure water applied or schedule irrigation. Cattle operations graze irrigated pastures and meadows scattered throughout the subbasin along with range and forestlands. Pastures are generally flood irrigated and are supplied by streams. Most farm irrigation diversions lack water measuring devices. Mixed conifer forests are found at higher elevations and are generally operated as industrial forests. Range sites are dominated by Western Juniper and are generally in poor condition. Wildlife habitat is generally wetlands in the state wildlife refuge or on national grasslands. Approximately 26 miles of streams on private lands have inadequate riparian vegetation.

Generally, streams in the upper portions of the subbasin support good populations of Brown and Rainbow trout. The Tulelake National Wildlife Refuge and Lower Klamath Lake National Wildlife Refuge support large populations of migratory and permanent waterfowl. Farmland on the refuges is leased to area farmers to supply grain for the waterfowl and shorebirds. The large bird populations depend on the refuges, leased lands and adjacent farms throughout the fall and spring migratory periods for habitat. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds. Conservation Accomplishments In the Butte Valley Subbasin during the last two years, some conservation progress has been made.

Other than limited contributions to groundwater in the Upper Klamath Basin, reductions in water demand only benefit the subbasin. Sprinkler- irrigated hay, cereal crops and row crops dominate land use on the better soils. Highly effective conservation on hay and cropland should focus on improving the overall irrigation efficiency of existing systems. This can be accomplished by upgrading systems and scheduling irrigation. An estimated 40 percent of the existing systems would benefit from maintenance. On controlled flood irrigated pastures, there are opportunities for land leveling or smoothing, lining or piping delivery ditches, and recovering tailwater.

Nearly half of the area is in public ownership. Iron Gate and Copco reservoirs are used extensively for recreational fishing, boating and camping. Whitewater rafting and kayaking are popular below the KC Boyle Dam. The KC Boyle, Copco and Iron Gate dams are used and regulated for power generation. Irrigated agriculture occurs on only 4,000 acres of pasture. Only a few isolated ranches are located in this subbasin. Cattle operations rotate grazing of irrigated pastures with significant acreage of grazed range and forest. Pastures are surface irrigated with a mix of controlled and flood irrigation. All irrigation water is diverted from the river or tributary streams. Most farm irrigation diversions lack devices to measure water. Even though overall irrigation application efficiency is low, the proximity of irrigated pastures to the river allows most excess water diverted to be reused downstream. Private forest and rangelands make up most of the private land, nearly all of which is used for livestock grazing. Much of the rangeland is in poor condition, with heavy juniper encroachment. More than half of the forest stands are overstocked with trees. Wildlife habitat along riparian areas is generally in good condition. Of the 12 miles of riparian areas surveyed, five would benefit from some restoration.

Water withdrawals are insignificant along this stretch of the river. Salmon and steelhead are blocked at Iron Gate Dam from upstream passage. Several resident trout species exist, supporting a recreational fishery. Conservation Accomplishments In the Klamath River East Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved the condition of natural resources on 56 acres of cropland, 332 acres of grazing land, and 560 acres of irrigated lands. They have also improved forestland health on 46 acres and have restored 924 acres of riparian and wetland areas.

This will also improve forage production, habitat condition and water quality in area streams, as well as reduce the opportunity for a catastrophic fire. There are opportunities for land smoothing and tailwater recovery systems to improve overall irrigation efficiency and effectiveness.

In this report are many kinds of basic information about the soils in the area. This information can be helpful in making decisions about the management of irrigated soils for optimum crop production, in planning land uses for urban and suburban areas, and in determining the needs for many other uses, for example, forestry, range, wildlife, and recreation. This soil survey has been prepared for many different users. Farmers can use it to help select the most suitable crop for the kind of soil; ranchers can use it to determine amount of forage production and the kinds of plants most suited to range or woodland; foresters can use the survey to find information about kinds of trees, potential for tree growth, and special soil features.

  	Citation × Citation Citation Abstract Copy Title: Status of Oregon's bull trout : distribution, life history, limiting factors, management considerations, and status Author: Buchanan, David V; Hanson, Mary L; Hooton, Robert M Year: 1997, 2007, 2005 EXECUTIVE SUMMARY Limited historical references indicate that bull trout Salvelinus confluentus in Oregon were once widely spread throughout at least 12 basins in the Klamath River and Columbia River systems. No bull trout have been observed in Oregon's coastal systems. A total of 69 bull trout populations in 12 basins are currently identified in Oregon. A comparison of the 1991 bull trout status (Ratliff and Ho well 1992) to the revised 1996 status found that 7 populations were newly discovered and 1 population showed a positive or upgraded status while 22 populations showed a negative or downgraded status. The general downgrading of 32% of Oregon's bull trout populations appears largely due to increased survey efforts and increased survey accuracy rather than reduced numbers or distribution. However, three populations in the upper Klamath Basin, two in the Walla Walla Basin, and one in the Willamette Basin showed decreases in estimated population abundance or distribution. Some Oregon river basins have bull trout populations at extreme risk of extinction. This statewide status review listed only 19% of the bull trout populations in Oregon with a ulow risk of extinction" or "of special concern." Therefore, 81% of Oregon's bull trout populations are considered to be at a "moderate risk of extinction," "high risk of extinction," or "probably extinct." Populations in the Hood, Klamath, and Powder basins, as well as the Odell Lake population in the Deschutes basin, which contain only a few remaining bull trout, are examples of populations having a "moderate" or "high risk" of extinction. Approximately 55% of current bull trout distribution occurs on lands managed by the U.S. Forest Service. A much smaller proportion occurs on Bureau of Land Management managed lands (2%). Only 16% of current bull trout distribution occurs within a protected area defined as Wilderness, Wild and Scenic River, or within a National Park. The Northwest Forest Plan, Inland Native Fish Strategy, and Interim Strategies for Managing Anadromous Fish-producing Watersheds in Eastern Oregon and Washington, Idaho, and Portions of California have provided increased protection for bull trout habitat depending on their scope and geographic areas affected, and the extent to which they are being effectively implemented in watersheds containing bull trout. Recent reduction in timber production on National Forests (up to 50% in western Oregon National Forests and over 30% in eastern Oregon National Forests) should help improve riparian and stream habitat conditions for bull trout. The remaining bull trout distribution occurs on private, state, or tribal owned lands. A comparison of approximately 39 locations throughout the state with protective angling regulations on bull trout (in some areas more than one bull trout population is protected by one regulation) shows that all state managed areas were upgraded in a protective angling status or at least maintained in 1996 compared to 1989. Restrictive angling regulations prohibit angler harvest of all bull trout populations in Oregon except for one in the Deschutes Basin. Restrictive bull trout angling regulation changes (including the elimination of bull Vll trout harvest in all spawning areas) may be the major reasons why the Metolius River/Lake Billy Chinook and mainstem McKenzie River populations have shown significant increases in abundance. Statewide stocking of non-native brook trout, including the high lakes stocking program, has been discontinued in locations where managers believe brook trout could migrate downstream and potentially interact with native bull trout. Hatchery stocking of legal rainbow trout to promote recreational fisheries has been discontinued in most locations near bull trout populations to avoid incidental catch of bull trout. The spatial and temporal distributions of bull trout reported for each river basin in this status report should be used as an accurate baseline for fisheries managers. Current distribution and relative change of distribution should be useful indicators of population health and status. The GIS maps in this report provide a template to add new layers of data such as critical spawning and juvenile rearing areas, or as a method to compare distribution changes through time. Length frequency data are presented for most Oregon bull trout populations. This should provide estimates for the presence of multiple age classes and the percent of fluvial size life history component.

This is the sixth report on the Oregon Plan for Salmon and Watersheds. The report provides an update on the accomplishments and continuing efforts of people throughout Oregon to improve and protect clean water and recover and maintain healthy populations offish and wildlife in our watersheds. The Oregon Plan is unique because it engages communities in the restoration and long-term stewardship of their watersheds. This extraordinary effort encourages local partnerships and voluntary actions to improve the conditions of our watersheds. Over the years, these actions have made Oregon a national leader in local cooperative conservation. This report collects project and condition data, voluntary private lands restoration information, and agency program accomplishments under the Oregon Plan. Consistent with the past two reports, this document continues to provide specific data on each of the state's fifteen reporting basins. A new element to this report is the inclusion of stories about the people, partnerships, and on-the-ground projects that are benefiting watersheds and communities across the state.

(Annett Brigitte), 1970- Year: 2008 Klamath River Water Quality and Acoustic Doppler Current Profiler Data from Link River Dam to Keno Dam, 2007 By Annett B. Sullivan, Michael L. Deas, Jessica Asbill, Julie D. Kirshtein, Kenna Butler, Roy E. Wellman, Marc A. Stewart, and Jennifer Vaughn Abstract In 2007, the U.S. Geological Survey, Watercourse Engineering, and Bureau of Reclamation began a project to construct and calibrate a water quality and hydrodynamic model of the 21-mile reach of the Klamath River from Link River Dam to Keno Dam. To provide a basis for this work, data collection and experimental work were planned for 2007 and 2008. This report documents sampling and analytical methods and presents data from the first year of work. To determine water velocities and discharge, a series of cross-sectional acoustic Doppler current profiler (ADCP) measurements were made on the mainstem and four canals on May 30 and September 19, 2007. Water quality was sampled weekly at five mainstem sites and five tributaries from early April through early November, 2007. Constituents reported here include field parameters (water temperature, pH, dissolved oxygen concentration, specific conductance); total nitrogen and phosphorus; particulate carbon and nitrogen; filtered orthophosphate, nitrite, nitrite plus nitrate, ammonia, organic carbon, iron, silica, and alkalinity; specific UV absorbance at 254 nm; phytoplankton and zooplankton enumeration and species identification; and bacterial abundance and morphological subgroups. The ADCP measurements conducted in good weather conditions in May showed that four major canals accounted for most changes in discharge along the mainstem on that day. Direction of velocity at measured locations was fairly homogeneous across the channel, while velocities were generally lowest near the bottom, and highest near surface, ranging from 0.0 to 0.8 ft/s. Measurements in September, made in windy conditions, raised questions about the effect of wind on flow. Most nutrient and carbon concentrations were lowest in spring, increased and remained elevated in summer, and decreased in fall. Dissolved nitrite plus nitrate and nitrite had a different seasonal cycle and were below detection or at low concentration in summer. Many nutrient and carbon concentrations were similar at the top and bottom of the water column, though ammonia and particulate carbon showed more variability in summer. Averaged over the season, particulate carbon and particulate nitrogen decreased in the downstream direction, while ammonia and orthophosphate concentrations increased in the downstream direction. At most sites, bacteria, phytoplankton, and zooplankton populations reached their maximums in summer. Large bacterial cells made up most of the bacteria biovolume, though cocci were the most numerous bacteria type. The cocci were smaller than the filter pore sizes used to separate dissolved from particulate matter in this study. Phytoplankton biovolumes were dominated by the blue-green alga Aphanizomenonflos aquae most of the sampling season, though a spring diatom bloom occurred. Phytoplankton biovolumes were generally highest at the upstream Link River and Railroad Bridge sites and decreased in the downstream direction. Zooplankton populations were dominated by copepods in early spring, and by cladocerans and rotifers in summer, with rotifers more common farther downstream. l Title: Klamath River water quality and acoustic Doppler current profiler data from Link River Dam to Keno Dam, 2007 Author: Sullivan, Annett B.

Oregon. 2005 M.Wood By Gene R. Hoilman, Mary K. Lindenberg, and Tamara Abstract During June-October 2005, water quality data were collected from Upper Klamath and Agency Lakes In Oregon, and meteorological data were collected around and within Upper Klamath Lake. Data recorded at two continuous water quality monitors In Agency Lake showed similar temperature patterns throughout the field season, but data recorded at the northern site showed more day-to-day variability for dissolved oxygen concentration and saturation after late June and more day-to-day variability for pH and specific conductance values after mid-July. Data recorded from the northern and southern parts of Agency Lake showed more comparable day-to-day variability in dissolved oxygen concentrations and pH from September through the end of the monitoring period. For Upper Klamath Lake, seasonal (late July through early August) lows of dissolved oxygen concentrations and saturation were coincident with a seasonal low of pH values and seasonal highs of ammonia and orthophosphate concentrations, specific conductance values, and water temperatures. Patterns in these parameters, excluding water temperature, were associated with bloom dynamics of the cyanobacterium (blue-green alga) Aphanizomenonflos-aquae in Upper Klamath Lake. In Upper Klamath Lake, water temperature in excess of 28 degrees Celsius (a high stress threshold for Upper Klamath Lake suckers) was recorded only once at one site during the field season. Large areas of Upper Klamath Lake had periods of dissolved oxygen concentration of less than 4 milligrams per liter and pH value greater than 9.7, but these conditions were not persistent throughout days at most sites. Dissolved oxygen concentrations in Upper Klamath Lake on time scales of days and months appeared to be influenced, in part, by bathymetry and prevailing current flow patterns. Diel patterns of water column stratification were evident, even at the deepest sites. This diel pattern of stratification was attributable to diel wind speed patterns and the shallow nature of most of Upper Klamath Lake. Timing of the daily extreme values of dissolved oxygen concentration, pH, and water temperature was less distinct with increased water column depth. Chlorophyll a concentrations varied spatially and temporally throughout Upper Klamath Lake. Location greatly affected algal concentrations, in turn affecting nutrient and dissolved oxygen concentrations—some of the highest chlorophyll a concentrations were associated with the lowest dissolved oxygen concentrations and the highest un-ionized ammonia concentrations. The occurrence of the low dissolved oxygen and high un-ionized ammonia concentrations coincided with a decline in algae resulting from cell death, as rn.easu.red by concentrations of chlorophyll a. Dissolved oxygen production, rates in. experim.en.ts were as high as 1.47 milligrams of oxygen per liter per hour, and consumption rates were as much as -0.73 milligrams of oxygen per liter per hour. Dissolved oxygen, consumption rates measured in. this study were comparable to those measured in a 2002 Upper Klamath Lake study, and a higher rate of dissolved oxygen consumption was recorded in. dark bottles positioned higher in the water column. Data, though, inconclusive, indicated that a decreasing trend of dissolved oxygen productivity through July could have contributed to the decreasing dissolved oxygen concentrations and percent saturation recorded in Upper Klamath Lake during this time. Phytoplankton self-shading was evident from, a general inverse relation between depth of photic zone and chlorophyll a concentrations. This shading caused net dissolved oxygen consumption during daylight hours in lower parts of the water column that would otherwise have been in the photic zone. Meteorological data collected in and around Upper Klamath Lake showed that winds were likely to come from a broad range of westerly directions in the northern one-third of the lake, but tended to come from a narrow range of northwesterly directions over the main body of the lake farther south.
