Public Review Draft 4- 27- 05 Conservation Plan Miller Lake Lamprey, Lampetra ( Entosphenus) minima April, 2005 Executive summary - The Miller Lake Lamprey was believed extinct after a chemical treatment in 1958, targeting lamprey and tui chub, extirpated both from Miller Lake. 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.

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.

We, the U.S. Fish and Wildlife Service (Service), announce a revised 90-day finding for a petition to remove the Lost River sucker [Deltistes luxatus) and shortnose sucker [Chasmistes brevirostris) throughout their ranges from the Federal List of Threatened and Endangered Wildlife and Plants (List), pursuant to the Endangered Species Act (Act) (16 U.S.C. 1531 et seq.). We find that the petition does not present substantial scientific or commercial information indicating that delisting of the Lost River and shortnose suckers may be warranted. As a result of the 1995, 1996, and 1997 fish die-offs, the endangered suckers experienced significant losses of thousands of adult suckers and have not recovered. Although the petition and information in our files do not provide new information relevant to the status of the Lost River and shortnose suckers, we are initiating a 5-year review of these species under section 4(c)(2)(A) of the Act to consider any new information that has become available as a result of recent actions to reduce threats to the species, and to provide the States, tribes, agencies, university researchers, and the public an opportunity to provide information on the status of the species. We are requesting any new information on the Lost River and shortnose suckers since their original listing as endangered species in 1988 (53 FR 27130)

Executive Summary This report provides information describing the biological, hydrological, meteorological, and water quality conditions associated with the die-off of an estimated 34,056 fish in the Klamath River, California in September 2002. The proximate cause of death was heavy infections of two fish pathogens, Ich and columnaris. However, given that these ubiquitous pathogens are normally found in the Klamath River, additional factors must have played a role for them to have become lethal. It is our conclusion based on multiple lines of evidence that the fish die-off in the lower Klamath River in 2002 was a result of a combination of factors that began with an early peak in the return of a large run of fall Chinook salmon. Low river discharges apparently did not provide suitable attraction flows for migrating adult salmon, resulting in large numbers of fish congregating in the warm waters of the lower River. The high density offish, low discharges, warm water temperatures, and possible extended residence time of salmon created optimal conditions for parasite proliferation and precipitated an epizootic of Ich and columnaris. Based on a review of available literature and historical records, this was the largest known pre-spawning adult salmonid die-off recorded for the Klamath River and possibly the Pacific coast.

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.

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
