  Citation × Citation Citation Abstract Copy Title: Fish Management Plan Detroit Reservoir 1982 Abstract -- Detroit Reservoir is a 3,580 acre Corps of Engineers multipurpose reservoir located at river mile 48.5 on the North Santiam River. The dam is located just below the confluence of the North Santiam and Breitenbush rivers. The reservoir was impounded in 1953 and is 9 miles long and over 1 mile at its widest point. Surface elevation is 1,569 ft at full pool. The reservoir is located about 50 miles east of Salem and road access is via State Highway 22. A large overnight campground and a day use area, both with boat launching facilities, are maintained by the Parks and Recreation Division of the Oregon Department of Transportation. The U.S. Forest Service (USFS) maintains two campgrounds on the south side of the reservoir, and there are two commercial boat concessions near the town of Detroit. Most of the area surrounding the lake is USFS land, although there are some private homesites on the North Santiam arm near Detroit. The reservoir receives heavy recreational use during the spring and summer months, including fishing, swimming, boating, camping, and water skiing. Fish passage structures were not incorporated in either Detroit or Big Cliff (reregulating dam) dams and consequently some 82 miles of stream are no longer available to former runs of spring chinook salmon and winter steelhead. In July 1982, the Oregon Fish and Wildlife Commission accepted the Department's recommendation to manage Detroit Reservoir for hatchery fish.

  Citation × Citation Citation Abstract Copy Title: Burnt River Basin Master Plan for Angler Access and Associated Recreational Uses 1966 Abstract -- The Burnt River headwaters are found along the southwestern Baker County line. The North, South, and Middle Forks join at Unity Reservoir about five miles north of the town of Unity. Below Unity Dam, the river makes its way through the Burnt River Valley. The 63.5 miles of the main river below Unity Dam is heavily infested with rough fish. To produce a good fishery, the river would need rehabilitation that would include: 1) Chemical treatment of the river and tributaries to remove the rough fish population. 2) Reintroduction of suitable fish species. 3) Construction of a barrier at downstream end to prevent upstream migration of rough fish from lower impoundments; e.g., Brownlee Reservoir. With the removal of rough fish, trout and warm-water game fish could be established and would produce good angling. At present, the trout fishery is confined to Unity Reservoir and the area directly below the dam. Trout angling on the forks of the system is limited and restricted to the early spring. Warm-water game fish are taken in the lower river in early spring.

To protect this population, we need to more fully understand the movement and habitat use of bull trout in the South Fork McKenzie watershed, and to develop an emergency action plan should environmental conditions become detrimental to the overall health of the population. Recommendations from this project will be made to the Environmental Coordination Committee in the event that actions to protect bull trout become necessary.

  Citation × Citation Citation Abstract Copy Title: Migration Characteristics of Hatchery and Natural Spring Chinook Salmon Smolts from the Grande Ronde River Basin, Oregon, to Lower Granite Dam on the Snake River Abstract -- Smolts of spring Chinook salmon Oncorhynchus tshawytscha experience substantial mortality while migrating through free-flowing reaches of the Snake River basin before reaching Lower Granite Dam, the first dam encountered in the Columbia–Snake river hydrosystem. We investigated the patterns of travel time and survival of hatchery and natural smolts fitted with passive integrated transponder (PIT) tags through specific reaches of the migration corridor during the 2000–2006 migration years for two populations originating in the Grande Ronde River basin (Lostine River and Catherine Creek). For both populations, median travel times for natural smolts were significantly longer in the upper reaches of the migration corridor but shorter in the lower reaches than for their hatchery counterparts. Also, among both hatchery and natural smolts, smaller individuals spent more time in the upper reaches, presumably feeding to attain a larger size before continuing their migration. Within populations, both hatchery and natural smolts showed similar patterns of survival through the reaches of the migration corridor above Lower Granite Dam. Size-selective mortality was evident for hatchery and natural smolts from both populations, especially in the upper reaches, larger individuals experiencing higher survival. The Catherine Creek population experienced the majority of natural and hatchery smolt mortality (32.8–65.8%) in a relatively short (91-km), low-gradient reach immediately below the summer rearing habitat. In contrast, the Lostine River natural and hatchery smolts experienced lower mortality (3.6–46.1%) in a 174-km reach below the summer rearing habitat. The results of this study demonstrate the dynamic nature of survival and migration rate among spring Chinook salmon smolts during their initial seaward migration from tributaries.

  Citation × Citation Citation Abstract Copy Title: Upper Deschutes River Fish Management Plan - Draft Abstract -- The Upper Deschutes River Fish Management Plan provides information on habitat, fish management, location and ownership, fish stocking history, angling regulations, management issues and management alternatives. In the Habitat and Fish Management sections of the following discussion, the Deschutes River will be divided into two sections; Wickiup Dam to Benham Falls, and Benham Falls to Bend (North Canal Dam). The reason for this is based on stream morphology and changes in fish populations. Benham Falls is a high gradient natural cascade which separates the Deschutes River into two logical sections with low gradient above the falls and high gradient below. Similarly, fish population composition changes at Benham Falls with brown trout dominant above and rainbow trout dominant below. The remaining sections; location and ownership, fish stocking history, angling regulations, management issues, summary of alternatives and alternatives will be presented as (1) Deschutes River, and (2) Tributaries.

  Citation × Citation Citation Abstract Copy Title: Survey of Crescent Lake, 1964 Abstract -- Crescent Lake, one of the impressive mountain lakes of Oregon, is located in Township 24 South, Range 6 East, on the east slope of the Cascade Range just southeast of Diamond Peak. Its south shore is skirted by the old Oregon Central Military Road, and the Southern Pacific Cascade Line passes a little to the east of the lake. It was named for its shape by B.J. Pengra and W.H. Odell in July, 1865. A dam located at the mouth of Crescent Lake was first constructed in 1922 to be used for irrigational purposes. Later, in 1954, another larger dam was constructed. The purpose of surveying Crescent Lake was to obtain the necessary physical, chemical and biological characteristics needed for fishery management. Also presented in this report are past records of creel censusing, gill netting, fish stocking, water temperatures, and water levels.
