  Citation × Citation Citation Abstract Copy Title: Downstream rearing of juvenile Chinook salmon abundance, distribution and growth in the Upper Mainstem of the John Day River Abstract -- Juvenile spring Chinook (Oncorhynchus tshawytscha) emerge from the gravel in the late winter or early spring, and most follow a life history pattern known as Natal Reach Rearing (NRR) in which juvenile fish remain in the stream reaches where they were spawned until their second spring of life when they start migrating towards the ocean (Healey 1991). However, in Columbia River tributaries, some juveniles have been observed following a Downstream Rearing (DSR) life history, in which they start moving downstream during their first spring towards other nursery habitats or perhaps ocean rearing (Copeland & Venditti 2009; Schroeder et al. 2016). Rearing in different habitats during their first year gives fish with these two life histories access to diverse food resources and, it is hypothesized that, this leads to different survival and growth advantages for these two groups. Differences in growth are of interest in efforts to conserve this threatened species because size is positively correlated to survival for salmon across multiple stages of their life cycle (Groot & Margolis 1991; Healey 1991; Quinn & Peterson 1996; Roni et al. 2012) Chinook salmon in the upper John Day River, Oregon, exhibit both NRR and DSR life history patterns. Fish following the DSR life history pattern are larger than NRR fish late in the spring, possibly due to factors such as higher fish density, lower stream productivity, and colder water temperatures in their natal reach than in the downstream reaches. However, this size advantage may be lost due to adverse summer conditions. Hot summer days combined with the withdrawal of water for agriculture lead to stream water temperatures well above lethal thresholds for salmon in many downstream reaches. DSR fish have been observed in tributaries of the mainstem John Day River, however their growth and survival during summer is unknown.

No work was undertaken on this job in FY 1982. Funds were used to offset increased costs of Job 4. Job 4 Summary: Our goal is to determine the factors important in limiting the production of wild and hatchery reared coho salmon in Oregon. Tasks for FY 1982: During FY 1982 we planned to: (1) prepare a review paper on past coho release strategies and develop recommendations for changes that may increase coho production from Oregon hatcheries; (2) complete all logistics and implement, the release of three groups of coho in the ocean release experiment; and (3) develop an historical data base of physical oceanographic factors that may influence coho salmon survival and growth. Accomplishments in FY 1982: An information report on coho release strategies was completed (Johnson 1982). The ocean release experiment was conducted in June 1982. We have obtained and tabulated historical records of upwelling indices, sea level measurements, sea surface temperature records, and spring upwelling transition dates.

  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.

  Citation × Citation Citation Abstract Copy Title: Klamath River (Below Keno Dam) Trout Management Program Including Spencer Creek 1978 Abstract -- The Klamath River is an extremely productive stream, but below Keno Dam it suffers from water fluctuation, poor water quality, lack of spawning gravel, and competition. The stream below Keno Dam and below the Boyle powerplant fluctuates from power production and irrigation manipulation. The five-mile section immediately downstream from Boyle Dam is the only portion that remains relatively stable. Low quantitites of dissolved oxygen and high water temperatures are chronic problems in the Keno area and adversely affect the river downstream. Most spawning gravel is located in Spencer Creek. The main river has a poor gravel supply. Competition from the various fish species in Boyle Reservoir has undoubtedly impacted the trout population and the spawning run into Spencer Creek. The Klamath River may be the most productive stream in Oregon. Although it has limitations on its production capabilities, it will be managed for wild trout only.

  Citation × Citation Citation Abstract Copy Title: Siuslaw River Basin Fish Management Plan 1997 Abstract -- The Siuslaw River Basin is one in a series of similar watersheds in the Oregon coastal mountain range extending from the Nehalem to the Coquille. Rivers and streams in these watersheds generally occur in a forest dominated landscape, have moderate gradients, and medium to large estuaries. There are few dams that substantially affect anadromous fish runs. Water withdrawals impact only a small portion of the total miles of stream habitat. Water quality and temperatures are suitable for salmonids for the entire year in most areas. Rainfall throughout the area is heavy, resulting in a high density of streams relative to watershed area. The Siuslaw River system alone has over one thousand contiguous miles of stream suitable for salmonids. Some of these stream reaches are highly productive, while others are severely degraded.

Rivers and streams in these watersheds generally occur in a forest dominated landscape, have moderate gradients, and medium to large estuaries. There are few dams that substantially affect anadromous fish runs. Water withdrawals impact only a small portion of the total miles of stream habitat. Water quality and temperatures are suitable for salmonids for the entire year in most areas. Rainfall throughout the area is heavy, resulting in a high density of streams relative to watershed area. The Yachats River system has about 69 contiguous miles of stream suitable for salmonids. Some of these stream reaches are highly productive. The Yachats River Basin has traditionally been managed for production of wild salmonids. Few hatchery fish have been released in the Yachats River Basin historically and none has been released in the past several decades. All salmonid species in the Yachats River Basin are at depressed levels with the exception of resident cutthroat trout. The depressed status of Yachats River Basin fish stocks has resulted from human induced factors including habitat degradation, excessive harvest, and hatchery influence (from adjacent streams) in combination with natural events such as droughts, floods and El Nino ocean conditions. As human induced factors are controlled and corrected, it is expected that fish abundance will increase substantially, but it is not possible to accurately forecast the shape recovery will take. In addition to the confounding effects of natural environmental variation, the recovery of individual fish species due to reduction in human impacts can only be loosely surmised. For this reason, this management plan will treat specific management targets for individual species as secondary to recovery of the entire basin and assemblage of fish species.

The information was collected as part of a major John Day River fish screening program designed to protect juvenile Salmon and Steelhead from perishing in irrigation diversion ditches throughout the John Day Basin. The program was started and funded in 1952 under the Columbia Program Office of the National Marine Fisheries Service. The actual construction, operation and maintenance of the fish screens was done under contract by the then Oregon State Game Commission (OSGC), later to become the Oregon Department of Fish and Wildlife. These Data were actually collected on site by the screen maintenance technicians hired by OSGC to service and maintain the installed screens and bypass fish traps. At least one or more bypass traps were installed on each major stream with screens throughout the basin and all fish caught in the screen bypass traps throughout the irrigation season were counted to evaluate the effectiveness of the program. These technicians would check the traps and take stream temperatures from one to five times per week throughout the irrigation season which usually ran in the early years from mid March through mid November. The central maintenance shop for the John Day fish screen program was constructed in 1952-53 near Canyon City, Oregon and operateq in that location for over forty years (1953- 1994) until a new facility was built west of John Day, Oregon in 1994.

The climate of this region is semiarid, characterized by low winter and high summer temperatures. There are at the present time only six bodies of water available for public angling within the county. Prineville and Ochoco Reservoirs are 3,000 and 1,200 acres respectively, and represent 95% of the total water area available to the public. The others are either small reservoirs or ponds with a combined area of less than 225 surface acres. An additional two reservoirs and two private lakes have been recommended for future development . The fishery consists primarily of rainbow trout and a light warm-water fishery in one of the reservoirs. The season opens in April and closes at the end of October, except for Prineville and Ochoco Reservoirs which are open to angling the entire year.
