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: A Trout Management Program for the Main Stem Lower Deschutes River 1978 Abstract -- The Deschutes River is a north flowing tributary of the Columbia River in Central Oregon and is a designated scenic waterway. Summer run steelhead and resident trout are the most important species to the local recreational fishery, although significant numbers of spring, summer, and fall chinook are also taken from the river. The salmon contribute significantly to fisheries in the Pacific Ocean and Columbia River and steelhead enter fisheries in the Columbia. The Deschutes also supports a good population of whitefish, lesser numbers of other trout species, small runs of coho and sockeye salmon, and several species of nongame fish.

  Citation × Citation Citation Abstract Copy Title: Fish Management Plan North Fork of Middle Fork Willamette River 1979 Abstract -- The North Fork is a moderate-sized tributary originating at Waldo Lake and entering the Middle Fork Willamette near the town of Oakridge. The river and its tributaries contain approximately 160 miles of trout producing water. The habitat is generally capable of producing a good trout population. Native cutthroat and rainbow are present throughout the system and brook trout, having moved out of Waldo Lake, are found a short distance downstream. In July 1979, the Oregon Fish and Wildlife Commission accepted the Department's recommendation to continue to manage the North Fork, Middle Fork Willamette River for wild trout. The Commission concurrently imposed a fly angling only restriction to fishing in this stream.

We also operated a rotary screw trap in the John Day River downstream of all tributary traps. These traps were operated from May throughout the contract period. A total of 94 westslope cutthroat trout were captured in all traps, ranging in size from 7 to 39 cm. The screw trap also captured 4,014 fish of six other species. We continued to track cutthroat trout with radio tags implanted in 1998 throughout the life of the tags. These fish displayed a variety of movements, including fluvial migrations from Roberts Creek into the mainstem John Day River, localized movements, and a suggestion of extensive movement. We prepared a draft report of that summarizes information about westslope cutthroat trout in the John Day Basin. We helped determine the distribution and abundance of bull trout and sympatric rainbow trout in four streams of the Middle Fork John Day River.

  Citation × Citation Citation Abstract Copy Title: Trout in Running Waters 1994 - Draft Abstract -- This chapter covers management of resident trout species in the Rogue, Applegate, and Illinois rivers and all associated tributary streams (running waters) of the Rogue River basin. Resident rainbow and resident, fluvial, and anadromous cutthroat trout are native to the Rogue River basin. Angling for trout in the Rogue River basin did not become popular until the 1930s. At this time, cutthroat and downstream migrating steelhead were abundant and easily caught from streams in settled areas of the Rogue basin. Mining roads provided easy access to the headwaters of the Applegate and Illinois rivers, Jumpoff Joe creek, and Grave creek where trout fishing was most popular. The California-Oregon Power Company developed roads that provided access to trout fishing waters in the Prospect area in 1912 and the upper Rogue River and its tributaries became accessible in 1927 when the Crater Lake Highway was completed. The Civil Conservation corps developed foot paths and roads into remote parts of the basin in the 1930s. Trout fishing in high pressure areas in the Rogue basin is maintained by stocking. A list of species and numbers of hatchery fish stocked in running waters of the Rogue River basin is presented in Appendix Table A-4.

  Citation × Citation Citation Abstract Copy Title: 2012 Trapper Creek Redd surveys Abstract -- Odell Lake was once directly connected to the upper Deschutes River basin, but recent geologic activity severed this connection with the creation of Davis Lake. Despite a lack of connection to the Deschutes River, indigenous bull trout (Salvelinus confluentus) subsist in Odell Lake. The Odell Lake bull trout are now the only natural adfluvial bull trout population in Oregon. Despite their persistence; angling mortality, habitat degradation, hybridization, and competition with introduced species limit bull trout populations. Bull trout were listed as threatened under the Endangered Species Act in 1998 (Office of the Federal Register 63 [June 10, 1998]: 31647). ODFW has monitored this population closely by conducting weekly redd counts on an annual basis and mapping redd locations to identify areas of optimal spawning habitat in Trapper Creek.

We radio-tagged a total of 41 adult cutthroat trout, including six from Deardorff Creek, 18 from Roberts Creek, and 17 from Rail Creek to initiate efforts to describe their seasonal movements. We began to measure the characteristics of habitats used by these fish. In August, we helped survey Vinegar Creek (Middle Fork John Day River subbasin) for the presence of bull trout. Vinegar Creek was thought to no longer support bull trout, but these surveys led to the discovery of one.

  Citation × Citation Citation Abstract Copy Title: Crooked River Fish Management Plan 1979 Abstract -- The Crooked River is a major tributary to the Deschutes River and has the habitat to produce a good rainbow trout population, especially between Prineville Dam and Rice-Baldwin Dam. However, winter streamflow is minimal and high turbidity is common. The. river is not stocked but various ages and sizes of hatchery fish emigrate from Prineville Reservoir during periods of spill; and these fish constitute a sizable portion of the trout population in the river. The Crooked River has maintained a successful fishery on the combination of wild and hatchery (from Prinevi11e Reservoir) trout under general statewide regulations. In July 1979, the Oregon Fish and Wildlife Commission accepted the Department's recommendation to continue to manage this portion of Crooked River for wild and hatchery fish. Hatchery fish will not be stocked in this section of the river, but large numbers of hatchery trout migrate from Prineville Reservoir into the river below the dam.

  Citation × Citation Citation Abstract Copy Title: NF - Movement of Juvenile Redband Trout from Spencer Creek, Klamath River in 2004: Preliminary Findings - Annual Report Abstract -- Spencer Creek is a major spawning area and recruitment source of redband trout in the upper Klamath River. The confluence of Spencer Creek and the Klamath River is 1.5 km upstream of J.C. Boyle dam, which was built in 1959. Past studies provide evidence of a dramatic decline in adult upstream passage since the dam was built and relatively little juvenile downstream passage. However, sampling efforts to quantify the magnitude and extent of movements by juveniles to locations downstream of the dam were limited in scope. Operation of J.C. Boyle Dam may reduce the likelihood that juvenile redband trout from Spencer Creek can move downstream past the dam safely and efficiently and may reduce adult upstream passage to Spencer Creek. In order to understand better juvenile and adult redband trout life history and evaluate fish passage over J.C. Boyle dam, Native Fish Investigations Project plans to monitor redband trout movement in Spencer Creek and the upper Klamath River during 2004 and 2005. We plan to capture juvenile trout (>90 mm) as they emigrate from Spencer Creek and tag them with inter-peritoneal radio transmitters (NanoTags, Lotek Wireless). Adults, upstream and downstream of the dam, will also be radio tagged. Movements of radio-tagged fish will be monitored using fixed-station receivers at locations associated with hydropower facilities and mobile receivers in free-flowing reaches. In addition, we plan to mark several hundred outmigrating juvenile trout (>70mm) in Spencer Creek, and 50 adult trout in the Klamath River, with passive integrated transponder (PIT) tags and install PIT-tag receiver stations at the mouth of Spencer Creek and downstream of J.C. Boyle Dam.
