We also sampled dependent population blocks across three monitoring strata (North Coast, Mid Coast, and Mid-South Coast). Using a spatially balanced site selection process (Generalized Random Tessellation Stratification; GRTS) we surveyed 451 unique sites within the range of coho salmon spawning or rearing. With the exception of the 2014 survey year, habitat data were collected during winter conditions (February – March). Habitat sampled in 2014 occurred within the summer field season (June – September). We used a Habitat Limiting Factors Model (HLFM) to estimate habitat capacity for winter coho parr and the HabRate model to assess habitat quality for each surveyed stream reach. HLFM estimates were expanded based on the total coho distribution in each population. Based on the habitat data the HLFM predicted the Floras population could support the highest density of juvenile coho (1568 parr/km), while the streams in the Siltcoos watershed could support the least (290 parr/km). At the ESU-level, there was no detectable change of high quality rearing habitat (= 1850 parr/km) when compared to previous studies, but changes were observed among populations over the course of these survey years. We compared individual habitat metrics across populations, land use, geology, and between independent and dependent populations. While no significant differences were observed between independent and dependent populations, differences in habitat metrics were detected among individual populations, land use types, and geologies. In addition, we detected a difference in reproductive habitat quality (spawning and emergence) between both populations and land use types.

  Citation × Citation Citation Abstract Copy Title: Comprehensive Plan for Production and Management of Oregon's Anadromous Salmon and Trout: Coastal Chinook Salmon Plan Abstract -- This is the fourth in a series of individual species plans concerning management of anadromous salmonid populations in the state of Oregon. This plan focuses on the actions the agency will take regarding chinook salmon Oncorhynchus tshawytscha populations produced in Oregon Coastal watersheds from the Necanicum River in the north to the Winchuck River at the Oregon-California border. Management of chinook salmon in the Columbia River basin is shaped by a cooperative agreement with the state of Washington, the Columbia River Treaty Indian Tribes, and the Federal Government. This management plan for wild and hatchery coastal chinook salmon in coastal river basins is the product of an ongoing planning process. The process began with the preparation of a report that contains descriptions of the life histories and assessments of recent trends in the run strengths of chinook salmon stocks in Oregon coastal river basins (Nicholas and Hankin 1988). ODFW staff and public representatives developed a comprehensive list of issues of concern and actions needed to improve management of coastal chinook salmon. These actions were based in part on a review of historic and contemporary habitat, harvest, and enhancement management practices in Oregon and on a review of the fisheries scientific literature.

  Citation × Citation Citation Abstract Copy Title: Fish Management Plan Drift Creek 1976 Abstract -- Drift Creek is being managed for wild fish. Good, basic information for management is available because data on cutthroat, steelhead, and coho salmon populations have been collected since 1959 as part of the Alsea Watershed Study. Drift Creek enters Alsea Bay at RM 3. It contains approximately 58 miles of fish production water and produces fair populations of resident cutthroat and good numbers of anadromous cutthroat, winter steelhead, and coho and chinook salmon. Fish have not been regularly stocked in Drift Creek, but all four species are released into the Alsea. The main stem of Drift Creek above Bohannon Falls is closed to salmon and steelhead fishing to protect spawning fish. Maintenance of water quality, summertime streamflows, riparian vegetation, and prevention of stream channel alterations are key elements in protecting the capability of this stream to sustain natural production of all salmonids. In July 1979, the Oregon Fish and Wildlife Commission accepted the Department's recommendation to manage Drift Creek for wild trout and steelhead. ·It was also decided to continue managing salmon by relying on natural production until we develop a coast-wide salmon management plan. At that time, staff biologists will decide on a final recommendation to the Fish and Wildlife Commission regarding the need or desirability for releasing hatchery salmon in the system.

The stream is about 62 miles long, but only 45 miles are available to anadromous fish. The watershed contains fair to good habitat, and physical stream survey information has been collected. Middle Creek contains resident and anadromous cutthroat trout, winter steelhead, and coho salmon. Hatchery fish are not released into the system. There are no special angling regulations in effect at present. In July 1979, the Oregon Fish and Wildlife Commission accepted the Department's recommendation to continue to manage Middle Creek for wild trout and steelhead. Choosing a management option for salmon will be deferred until ODFW develops a coast-wide salmon management plan. At that time, staff biologists will decide on a final recommendation to the Commission regarding the need or desirability for releasing hatchery salmon into Middle Creek.

  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.

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.

This project has adapted to and advanced the recent paradigm shift in juvenile coho life histories, rearing and foraging strategies, growth, survival, migrations, and sub-basin level population productivity in the tidal zone. Temporal and spatial components of coho over-winter rearing strategies, in relation to habitat use and project effectiveness monitoring, is the monitoring focus in the paired study streams of Palouse and Willanch Creeks. Project results further reveal the fundamental mechanisms that promote juvenile coho growth and survival in the estuarine ecotone. In conjunction with prior and current data, results highlight the critical importance of these diverse habitats for recovering viable and resilient Oregon Coast coho populations.

  Citation × Citation Citation Abstract Copy Title: Douglas County Lakes and Reservoirs Master Plan for Angler Access and Associated Recreational Uses 1968 Abstract -- Douglas County covers roughly 5,000 square miles of Southwest Oregon and is almost coincidental with the boundaries of the Umpqua River watershed. The topography consists of the Coast Range mountains in the west, a central valley area and the Cascade Mountains to the east. Other valley areas are scattered throughout the county. Most of the lakes and impoundments of the county are located in the Cascades to the west and along the coast to the east. While good roads link these lakes with the populated areas of the county, additional developments are needed on about 30 lakes to spread out tourist pressure and help provide quality recreation over more of the county. A few of the larger more popular lakes are crowded to and beyond capacity during the trout season. Potential impoundments for recreation have been recommended at 23 sites. A high priority is placed on establishing warm-water fisheries adjacent to communities where heavy utilization favors better fish growth. Old log-ponds are sometimes used to good advantage for this type of recreation. This report details a plan that we hope can be followed to solve the access problems of the Douglas County lakes and reservoirs.
