This program was funded by Bonneville Power Administration and was managed under the Fisheries Program, Department of Natural Resources, Confederated Tribes of the Umatilla Indian Reservation. An estimated 36.7 km (22.6 miles) of stream habitat were inventoried on the Umatilla River, Moonshine, Mission, Cottonwood and Coonskin Creeks. A total of 384 of 3,652 (10.5%) habitat units were electrofished. The number of juvenile fish captured follows: 2,953 natural summer steelhead (including resident rainbow tout; Oncorhynchus mykiss), one hatchery steelhead, 341 natural chinook salmon (0. tshawytscha), 163 natural coho salmon (0. kisutch), five bull trout (Salvelinus confluentus), 185 mountain whitefish (Prosopium williamsoni), and six northern squawfish (Ptychocheilus oregonensis). The expanded population estimate for the areas surveyed was 73,716 salmonids with a mean density of 0.38 fish/m2. The following number of non-salmonids were visually estimated: 7,572 speckled dace (Rhinichthys osculus), 5,196 sculpin (Cottus spp.), 532 suckers (Catostomus spp.) and 191 redside shiners (Richardsonius balteatus). The gross estimated density of all non-salmonids combined was 0.84 fish/m2. The estimated ratio of non-salmonids to salmonids was 2.4: 1. Relative salmonid abundance, seasonal distribution and habitat utilization were monitored at index sites throughout the basin. During index site monitoring, the following species were collected in addition to those listed above: american shad (Alosa sapidissima), smallmouth bass (Micropterus dolomieu), carp (Cyprinus Carpio) and chiselmouth (Acrocheilus alutaceus). Thirty ­nine sites were electrofished during the spring and summer seasons, while 36 sites were sampled in the fall season. Index sites with the. highest mean salmonid catch/minute (fish/min.) during the three sample periods were located at the following sites: East Birch Creek (3.4 fish/min.), Boston Canyon Creek (3.2 fish/min.), Spring Creek (3.1 fish/min.) and upper Squaw Creek (3.0 fish/min.). The highest electrofishing catch rates were observed in the Umatilla River tributaries above river mile (RM) 70 in the August and September sample period (Table J-2 catalogs river miles with associated landmarks). During the November sample period, catch rates were highest in Birch Creek tributaries. Most salmonids were captured in slow water near the bank during the November and March sampling periods. A study of the migration movements and homing requirements of adult salmonids in the Umatilla River was conducted during the 1994-95 return years. Radio telemetry was used to evaluate the movements of adult salmonids past diversion dams in the lower Umatilla River and to determine migrational movements of salmonids following upstream transport. Radio transmitters were placed in 30 summer steelhead, 15 spring chinook, nine fall chinook, and eight coho salmon. Salmon were released at Three Mile Falls Dam (TMD). An additional 11 summer steelhead and ten spring chinook salmon were tagged, hauled upstream, and released at either Barnhart, Nolin, Thornhollow, or Imeques C-mem-ini-kem. On average, summer steelhead required 36 days to successfully migrate from TMD to Stanfield Dam. Spring chinook required 18 days. Average passage times for summer steelhead (hours and minutes) at Westland, Feed Canal, and Stanfield Dams were 13:06, 83:24, and 2:58, respectively. Spring chinook salmon required 04:30 at Westland, 89:42 at Feed Canal, and 04:01 at Stanfield Dams. Migrational delays were observed at Feed Canal Dam at flows ranging from 563 to 1,601 cubic feet/second (cfs). Thirty-eight percent of the fish ladder at Westland Dam, 75% at Feed canal, and 31% at Stanfield Dam. Average passage times at Feed Canal Dam (1995) were more than 15 times those at Stanfield Dam in 1994 and more than 20 times those at Stanfield Dam in 1995. Data related to homing and passage needs of Umatilla River salmonids was investigated in an attempt to maximize homing to the Umatilla River. Straying rates of adult summer steelhead and spring chinook salmon were found to be low while coho and fall chinook salmon stray rates were high in some groups, particularly adult returns from subyearling smolt releases of fall chinook salmon. Attraction flows of from the mouth of the Umatilla River of at least 150 cfs were required to encourage migration and reduce straying of fall chinook and coho salmon. Significant numbers of summer steelhead entered when flows exceeded 500 cfs. Spring chinook salmon entry was variable with fish entering at flows ranging from 150 to more than 2,000 cfs. Adult anadromous salmonids potentially available to spawn above TMD from August 26, 1994 to June 27, 1995 included: 593 adult and 530 jack fall chinook salmon (1994 brood), 879 adult and 54 jack coho salmon (1994 brood), 784 natural and 509 hatchery summer steelhead (1995 brood), and 378 adult and 62 jack spring chinook salmon (1995 brood). During escapement surveys (fall of 1994), a total of 82 fall chinook salmon redds, 24 coho salmon redds and seven unidentified salmon redds (112 redds total, 2.6/mile) were enumerated along 42.3 miles of the mainstem above TMD. In 1995, we enumerated and flagged 126 summer steelhead redds (3.6 redds/mile) along 35.3 miles of lateral tributaries of the Umatilla River. Also enumerated were 90 spring chinook salmon redds (1.6 redds/mile) along 55.8 miles of the mainstem. Ninety-six percent of the adult fall chinook salmon carcasses examined had spawned while 94% of the coho had spawned; 66.8 % of the spring chinook salmon carcasses examined bad spawned. A total of 49.3% of spring chinook salmon released above TMD were sampled during spawning ground surveys and 60 coded wire tags (CWTs) were recovered from 78 adipose clipped fish. The rotary screw trap in the Umatilla River (RM 76) operated 63 of 113 days from September 21, 1994 to January 13, 1995. The trap captured 596 juvenile steelhead with a mean trap efficiency rate of 9.9%. A total of 1,368 juvenile chinook salmon were captured with a mean trap efficiency rate of 28. 8 % . The rotary screw trap at the Imeques C-mem-ini-kem site (RM 79.5) operated 43 out of 43 days from May 5 through June 16, 1995. The trap captured 304 natural juvenile steelhead with a mean trap efficiency rate of 6.6%. A total of 102 natural juvenile chinook salmon were captured with a mean trap efficiency rate of 10.5%. The rotary screw trap at the Barnhart site (RM 42,2) operated 87 out of 125 days from March 3 to June I, 1995. The trap captured 105 natural juvenile steelhead, 247 natural juvenile chinook salmon, five natural coho salmon, 6,265 hatchery juvenile chinook salmon, 467 hatchery steelhead and 16,844 hatchery coho salmon. Mean trap efficiency rates ranged from 2.3 to 5.7% . Harvest monitors estimated that tribal anglers harvested 25 hatchery and five natural summer steelhead during the spring of 1995. There was no spring chinook salmon fishery in the Umatilla River during 1995 because of the low number of returning adults. Scale analysis determined that over 85 .0% of naturally produced juvenile summer steelhead sampled during biological and index surveys were age O+ or l +. Naturally produced summer steelhead adults, returning to the Umatilla River in 1994-95, were mostly from the 1990 (46.4%) and 1991 (33.9%) brood years.

  Citation × Citation Citation Abstract Copy Title: Lower Umpqua Watershed Analysis, 1997 Abstract -- This analysis of the Lower Umpqua River watershed (2% of the total Umpqua River drainage area) in the southern Coast Range includes watershed characterization, issues, inherent landscape instability, aquatic species' habitat and population, terrestrial species' habitat and population, and restoration opportunities. This analysis was conducted by Siuslaw National Forest personnel with assistance from the Bureau of Land Management - Coos Bay District. The analysis was focused on fisheries and wildlife issues. The existing resource conditions were compared to expected natural conditions to assess trends in resource conditions. From this information, a strategy of restoration opportunities to enhance resource conditions on federal lands was developed. Watershed Analysis is one of the key components of the Aquatic Conservation Strategy (ACS) developed for the Northwest Forest Plan (NFP) (USDA-USDI 1994). The analysis is intended to facilitate watershed planning that: 1) achieves Aquatic Conservation Strategy and Late-Successional Reserve objectives and 2) provides the basis for monitoring and restoration programs.

  Citation × Citation Citation Abstract Copy Title: Comprehensive Plan for Production and Management of Oregon's Anadromous Salmon and Trout: Part I. General Considerations Abstract -- A comprehensive plan was prepared for managing Oregon's anadromous salmon and trout resources. The plan provides the basic framework for managing individual anadromous species, presenting an organized approach rather than an empirical approach to management problems. It also provides the primary focus for developing subsidiary management plans for individual subbasins. The management goals, status of the stocks, planning definitions, and administrative guidelines constraining the planning process are described or documented in developing the plan. The plan applies four fundamental concepts on wild fish, stocks, stock-recruitment relationships, and habitat requirements as underlying principles required for prudent management of anadromous fish resources. The concepts and their role in the planning effort are documented. Various economic goals and associated problems are described to attain efficient and equitable utilization of anadromous fish resources by harvesters and to satisfy the broader concerns of society in managing the stocks.

  Citation × Citation Citation Abstract Copy Title: Angler Surveyor Procedures Manual 2004; Willamette Salmonid Inventory Project Abstract -- The Willamette Salmonid Inventory Project is charged with the task of monitoring the status of naturally produced and hatchery produced salmonid stocks. One important aspect of this monitoring effort is an estimate of fish that are caught in recreational fisheries. State and Federal fishery managers use the results of these surveys to manage Oregon's fisheries resources. The goal of the river creels is to estimate effort and catch of marked and unmarked spring chinook, steelhead, and young salmonids, including catchable rainbow, cutthroat and juvenile chinook and steelhead. The basic approach is a roving creel in which the sampler travels up and down the river interviewing bank anglers and boat anglers as they are encountered. The sampler queries anglers about catch numbers, catch composition, time spent fishing and other auxiliary information. At assigned times during the sampled day; the sampler travels the length of the river counting boat trailers (without boats), individual bank anglers at some locations, and cars at other locations. The goal of these counts is to estimate the number of people fishing at a given time. The goal of the Foster Reservoir creel survey is to estimate angler effort and catch of juvenile winter steelhead and trout throughout the year. The fishery has been surveyed at a reduced level of sampling effort during the winter and is now ramped up to a full time sampler. The basic approach is similar to that for the river creels. The results of these surveys are used in a variety of ways: 1. They allow us to assess how well the hatchery programs are serving the public by giving an estimate of how many hatchery-produced fish are caught. 2. By combining creel data with counts at fish ladders and hatchery traps, we can construct a more reliable estimate of how many fish return to sub-basins of the Upper Willamette. 3. Creel data help us to evaluate the effectiveness of the hatcheries’ recycling programs. 4. Data on how many naturally-produced (unmarked) fish are caught and released allow us to estimate mortality for naturally-produced fish. 5. Coded wire tag data are also used in making estimates of run size, and give information on the origin and stray rates of hatchery fish in the fishery.

  Citation × Citation Citation Abstract Copy Title: Spring Chinook Salmon in the Willamette and Sandy Rivers, Progress Reports 2002, F-163-R-07 Abstract -- The Willamette and Sandy rivers support intense recreational fisheries for spring chinook salmon (Oncorhynchus tshawytscha). Fisheries in these basins rely primarily on annual hatchery releases of 5–8 million juveniles. Hatchery programs exist in the McKenzie, Middle Fork Willamette, North and South Santiam, Clackamas, and Sandy rivers mainly as mitigation for dams that blocked natural production areas. Some natural spawning occurs in most of the major basins and a few smaller tributaries upstream of Willamette Falls. The Oregon Fish and Wildlife Commission adopted the Wild Fish Management Policy to reduce adverse impacts of hatchery programs on wild native stocks (ODFW 1992a). The main goal of the policy is to protect the genetic diversity of these stocks recognizing that genetic resources are a major component, not only in sustaining wild stocks, but also in perpetuating hatchery programs and the fisheries they support. In the past, hatchery programs and fish passage issues were the focus of spring chinook salmon management in the Willamette and Sandy basins. Limited information was collected on the genetic structure among basin populations, on abundance and distribution of natural spawning, on rearing and migrating of juvenile salmon, or on strategies for reducing risks that large hatchery programs pose for wild salmon populations. This study is being implemented to gather this information. A schematic of the study plan is shown in APPENDIX A. We conducted work in the main-stem Willamette River at Willamette Falls, and in the Middle Fork Willamette, McKenzie, North Santiam, South Santiam, Molalla, Clackamas, and Sandy rivers in 2002. Basin descriptions and background information on management and fish runs can be found in subbasin plans developed by the Oregon Department of Fish and Wildlife (ODFW 1988, ODFW 1992b, ODFW 1992c, and ODFW 1996).

  Citation × Citation Citation Abstract Copy Title: A Plan for Reintroduction of Anadromous Fish in the Upper Klamath Basin 2008 Abstract -- The Oregon Fish and Wildlife Commission (OFWC) has adopted statewide species plans for Chinook and coho salmon, steelhead, trout, and warmwater gamefish. These plans guide the development of localized plans for species management units, and individual river basins. A fish management plan was adopted by the OFWC in 1997 for the Klamath River Basin. Basin fish management plans serve several functions. They present a logical, systematic approach to conserving our aquatic resources; establish management priorities, and direct attention to the most critical problems affecting our fisheries. In November 2002, the OFWC adopted the Native Fish Conservation Policy (NFCP) that calls for development of conservation plans for each species management unit to ensure conservation and recovery of native fishes in Oregon. Intent of the NFCP is to provide a basis for managing hatcheries, fisheries, habitat, predators, competitors, and pathogens in balance with sustainable production of naturally produced native fish. The policy has three areas of emphasis. The first is defensive, to ensure avoidance of serious depletion of native fish. The second is more proactive, to restore and maintain native fish at levels providing ecological and societal benefits. The third area of emphasis ensures that, consist with native fish conservation, opportunities for fisheries and other societal resource uses are not unnecessarily constrained. The NFCP acknowledges that basin fish management plans will provide fish management guidance until conservation plans can be completed. Title: A Plan for Reintroduction of Anadromous Fish in the Upper Klamath Basin 2008 Abstract -- The Oregon Fish and Wildlife Commission (OFWC) has adopted statewide species plans for Chinook and coho salmon, steelhead, trout, and warmwater gamefish. These plans guide the development of localized plans for species management units, and individual river basins. A fish management plan was adopted by the OFWC in 1997 for the Klamath River Basin. Basin fish management plans serve several functions. They present a logical, systematic approach to conserving our aquatic resources; establish management priorities, and direct attention to the most critical problems affecting our fisheries.

To meet the ISRP’s recommendation, the structure and methods employed by the Oregon Plan for Salmon and Watersheds Monitoring Program were extended to the John Day basin. This approach incorporates the sampling strategy of the U.S. Environmental Protection Agency’s (EPA’s) Environmental Monitoring and Assessment Program (EMAP). The EMAP is a long-term research effort with a statistically based and spatially explicit sampling design. This program applies a rigorous, Tier-2 sampling design to answer key monitoring questions, integrate on-going sampling efforts, and improve agency coordination. EMAP objectives specific to the John Day basin are to determine annual estimates of steelhead spawner escapement, hatchery to wild steelhead stray ratios, juvenile steelhead and other salmonid rearing distributions, physical habitat conditions, and track changes in the status and trends of these estimates over time. In addition, data from on-going projects in the basin, such as smolt monitoring, will be incorporated in future years to develop a more complete picture of status and trends in resources (e.g. life-stage specific survival) not targeted under the EMAP program. This project provides information as directed under two measures of the Columbia Basin Fish and Wildlife Program. Measure 4.3C specifies that key indicator naturally spawning populations should be monitored to provide detailed stock status information. In addition, measure 7.1C identifies the need for collection of population status, life history, and other data on wild and naturally spawning populations. This project was developed in direct response to the recommendations and needs of regional modeling efforts, the ISRP, the Fish and Wildlife Program, the Oregon Plan for Salmon and Watersheds, and the Columbia Basin Fish and Wildlife Authority Multi-Year Implementation Plan.

  Citation × Citation Citation Abstract Copy Title: Fish Management Plan Hosmer Lake 1990 Abstract -- Hosmer Lake and it's water supply are entirely in US Forest Service ownership. The lake and adjacent lands, are managed by the Forest under recreation and visual classifications. The water of the lake is state-owned and the fish resources are managed by the Oregon Department of Fish and Wildlife (ODFW). Hosmer Lake is a natural lake located about 40 miles west of Bend via County Road 46 (Century Drive) and Forest Road 470. One main campground, one overflow campground and a concrete boat ramp are managed by the Deschutes National Forest. Hosmer Lake covers 160 surface acres and lies at an elevation of 4,950 feet. Maximum water depth is 11 feet and most of the lake is very shallow. The only inlet to the lake is Quinn Creek, a spring-fed stream with a flow of 25 cfs and a near-constant temperature of 42°F. Hosmer Lake contains Atlantic salmon ("Salmo salar") and brook trout ("Salvelinus fontinalis"). The lake was chemically treated in 1957 to remove a population of carp ("Cyprinus carpio"), Tui chub ("Siphateles bicolor") and brook trout. The treatment successfully removed all carp and Tui chub, but not all brook trout. Non-game fish have not reappeared since 1957. Originally, it was hoped the Atlantic salmon would spawn successfully in Quinn Creek. However, they cannot ascend the six-foot falls in lower Quinn Creek. The pumice bottom and annual anchor-ice scouring also nullifies egg development. The population of salmon at Hosmer has been maintained soley by hatchery fish since 1958.
