  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.

Oncorhynchus mykiss exhibit a complex of life-history strategies ranging from residency in small headwater streams to anadromy involving migrations of hundreds of kilometers. In the Grande Ronde River basin of Northeast Oregon, both resident and anadromous life-history forms coexist, and thus populations found there likely exhibit partial migration. Partial migration may have important consequences for “anadromous” species listed under the Endangered Species Act (ESA). The recent decline of summer steelhead (Oncorhynchus mykiss) stocks in the lower Snake River has prompted their listing under the ESA. Declines in steelhead are potentially due to elevated mortality rates associated with anadromous migrations. If resident and anadromous life-history characteristics result from a phenotypically plastic trait (i.e. a genetic trait that is highly variable due to influences from environmental factors), then elevated mortality associated with the anadromous type may be shifting the populations towards residency. Further, although the anadromous expression of the trait may be declining, the trait would not necessarily be lost. Identification of the plasticity of these traits would then be important for the management of these stocks. We investigated life history traits of O. mykiss with studies in both the hatchery and natural environment. We anticipated that these complimentary approaches would allow us to evaluate the relationship between the two life-history forms. They should further allow us to explore the feasibility of using hatcheries to produce anadromous progeny from resident parents if the number of anadromous life-history forms becomes severely depressed.

  Citation × Citation Citation Abstract Copy Title: Sandy River Basin Fish Management Plan 1997 Draft Abstract -- The Sandy River and its tributaries originate high on the west and south slopes of Mount Hood, flow approximately 55 miles in a northwesterly direction and enter the Columbia River near Troutdale (Columbia RM 120.5). The Sandy basin is situated in Multnomah and Clackamas counties (EPA reach 17080001), and drains approximately 508 square miles. The Sandy River basin is comprised of several subbasins, many of which are uniquely distinct hydrologically and geomorphologically. Principle tributaries include the Zigzag River, Still Creek, and the Salmon River in the upper basin and the Bull Run River, Gordon, Cedar, and Beaver creeks in the lower basin. Many other smaller tributaries located throughout the basin contribute significantly to stream flows and provide habitat for a wide array of fish and wildlife assemblages. The Sandy River is well known for its sport fishing. Winter steelhead, summer steelhead, and spring chinook are the most sought after species. Both winter and summer steelhead, coho, and spring chinook are supplemented with hatchery produced fish. Rainbow trout and fall chinook are no longer stocked in flowing waters of the Sandy River basin. In the late 1980's the Northwest Power Planning Council administered a planning process to create a management plan for the Columbia River basin. As a part of that process, a subbasin plan concerning management of steelhead and salmon was written for the Sandy River basin. This document, the draft "Sandy River Basin Fish Management Plan", significantly expands on the Northwest Power Planning Council document by adding resident fish species and new information on anadromous species and will ultimately produce the final plan used to guide fish resource management in the basin for the next 5 to 10 years.

The lower Deschutes River subbasin as defined in this plan as the Deschutes River from the Pelton Reregulating Dam downstream to the Columbia River and all waters within that drainage area. This plan was developed in cooperation with the Confederated Tribes of the Warm Springs Reservation of Oregon (CTWS). The CTWS and the ODFW are co-managers of the fishery resources in the lower Deschutes River. Policy and objective statements contained in this plan are not applicable to waters on the CTWS reservation. Some policy and objective statements contained in this plan are in opposition to CTWS resource management strategies. The lower Deschutes River is classified as both state of Oregon and federal Wild and Scenic rivers. White River, a major tributary to the lower Deschutes, begins at White River Glacier on the southeast side of Mount Hood and flows 44 miles to its confluence with the Deschutes River. White River is classified as a federal Wild and Scenic river and has been nominated to be included in the state of Oregon wild and scenic river program. The lower Deschutes River is known nationally and internationally for its sport fishing. Resident trout, summer steelhead, spring chinook, and fall chinook are the most sought after species. The lower Deschutes River also supports important tribal fisheries for indigenous fishes. Both summer steelhead and spring chinook are supplemented with hatchery produced fish.

  Citation × Citation Citation Abstract Copy Title: Clear and Foster Creek Watershed Assessment Abstract -- A watershed assessment was completed in the Clear and Foster Creek watersheds to evaluate existing conditions and make recommendations to protect or enhance watershed natural resources. Clear and Foster Creek are tributaries to the Clackamas River below any major dams on the system; consequently these tributaries are positioned favorably to contribute to recovery of important anadromous fish populations. Anadromous fish species in the Clackamas basin include spring and fall chinook, coho salmon, winter steelhead, summer steelhead (non-native), migratory cutthroat trout and lamprey. Clear and Foster Creeks are utilized by fall chinook, winter steelhead and coho salmon. The assessment generally followed the framework described in the Oregon Watershed Enhancement Board’s Watershed Assessment Manual (WPN, 1999). The assessment focused on the following components: Channel habitat classification and modification; hydrology and water use; riparian/wetlands; sediment sources; water quality; fisheries; and wildlife and upland vegetation. Generally the approach builds on existing information, and enhances this information with aerial photo interpretation and limited field checking. Additional fieldwork was used to verify channel habitat types and to characterize fish habitat condition. GIS was used as a critical assessment tool and method of displaying results.

  Citation × Citation Citation Abstract Copy Title: Fish Use of the Estuary: 1999 Tillamook Bay Monitoring Report Abstract -- The study was conducted during the summer and autumn of 1998 and the spring and summer of 1999. The fish sampling done in 1998 was used to provide an estuary-wide overview of the fish species composition and relative abundance during the mid-summer period and to test sampling gear and sampling strategies for development of a long-term monitoring program. The sampling conducted in 1999 built upon the information gained in 1998 and provided an initial test of a sampling design for long-term monitoring of the Bay's fish community. Sampling of the fish community in 1998 was conducted using beach seine, bottom trawl, fyke net and round-haul net. During 1999, initial testing of the proposed long-term monitoring program was conducted using beach seine, trawl and fyke nets. A total of 40 fish species were collected during this study whereas a total of 59 species were captured during ODFW's surveys during the mid- 1970s. Of the 40 species captured in this study, all but four were present in the mid- 1970s. Eight of the ten most abundant species present in the mid-1970s were among the ten most abundant species captured in this study. All but one of the abundant species in the beach seine catch were found throughout the estuary. All five species of anadromous salmonids known to occur in the Tillamook Bay watershed were collected during this study. However, only juvenile chum and chinook salmon were caught in any abundance. The most abundant non-salmonid species in the estuary were euryhaline marine species.

  Citation × Citation Citation Abstract Copy Title: Indian Creek Aquatic Restoration (OWEB #205-144) Abstract -- Like many streams in this area, these creeks have experienced considerable habitat degradation due to past land management practices that removed large wood from the channels. Without the large wood, spawning gravels have washed away leaving a mostly bedrock substrate. The down-cut stream is no longer connected to its former floodplain and fish have little refuge during high flows. Additionally, aquatic insect life, the basic food source for young salmonids, is limited without the diverse habitats formed by complexes of wood and gravel. Goals associated with this restoration proposal include: • Address limitation to anadromous fish production in Indian Creek tributaries o Enhance spawning, rearing, and overwintering habitat for anadromous and resident fish species o Restore storage capacity (water, substrates, and detritus) of the selected streams to levels more closely expected with unaltered systems in the Coast Range. • Establish a connection between past small scale restoration efforts • Maintain a network of organizations, stakeholders, and individuals who will participate in watershed restoration efforts. Widened channel floodplain from newly derived gravel, side channel formation / channel alteration (with more sinuosity), and additional scour pools were observed throughout the structure sites we monitored since the project implementation from high water events. Especially, the amount of gravel that was delivered to the project reaches and the degree to which they were sorted in large concentration directly adjacent to the helicopter structures was far more prominent than what we have observed in previous years from other helicopter projects.

Status is monitored through spawning surveys. Species or races monitored through these surveys are fall chinook salmon (Oncorhynchus tshawytscha), coho salmon (O. kisutch), chum salmon (O. keta) and steelhead (O. mykiss). Assessments cover through the 2001 brood year for salmon and the 2002 brood year for steelhead. Status is generally assessed along two levels of geographic aggregation: Evolutionary Significant Units (ESUs) and Gene Conservation Areas (GCAs) or Monitoring Areas (MAs). ESUs were defined by the National Marine Fisheries Service in conducting reviews for protection under the federal Endangered Species Act. GCAs and MAs are usually subsets of ESUs and were defined by the Oregon Department of Fish and Wildlife either as part of the implementation of the Wild Fish Management Policy or as part of monitoring associated with implementation of the Oregon Plan for Salmon and Watersheds.

In 1960, nuisance management of bull trout ended and protection of bull trout began in 1983 with mandatory catch and release regulations throughout the Metolius River basin. In 1986, the Department initiated annual redd counts for bull trout throughout the basin to document the species status. Redd surveys showed low spawning numbers, and the Department responded by closing all tributaries downstream of Lake Creek to fishing in 1994. A Threatened listing of Columbia River bull trout under the Endangered Species Act in 1998 followed the fishery closure (Fies et al. 1996 and Lohr et al. ####). Bull trout redd counts continue in the basin in accordance with the goals of the Native Fish Conservation Policy.
