  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.

  Citation × Citation Citation Abstract Copy Title: Fish Management Plan Siuslaw River 1979 Abstract -- The Siuslaw River is a large system entering the Pacific Ocean near Florence. The system contains about 950 miles of stream and produces resident and anadromous cutthroat trout,winter steelhead, and coho and fall chinook salmon. Small numbers of spring chinook are found in the system and shad and striped bass are also present. Good numbers of wild fish of all species are produced in the Siuslaw and ODFW annually releases sea-run cutthroat and winter steelhead. Extensive fisheries have developed on this combination of wild and hatchery fish. There are no special angling regulations in effect at present other than an angling deadline on Lake Creek. Three private salmon hatcheries have received permits to release fish into the Siuslaw. Although these facilities have not yet obtained significant returns of adults, the potential exists for large numbers of hatchery adults to return to the system. In July 1979, the Oregon Fish and Wildlife Commission accepted the Department's recommendation to manage the Siuslaw River system, except for Triangle Lake and its tributaries, for wild and hatchery trout, steelhead, and salmon. Hatchery fish will be released in areas and at sizes and times to maximize their contribution to the sport fisheries in the system and to minimize their impact on the extensive wild fish populations present. Trout populations in Triangle Lake and its tributaries will be managed for wild fish.

  Citation × Citation Citation Abstract Copy Title: Factors that Influence Evolutionary Significant Unit Boundaries and Status Assessment in a Highly Polymorphic Species, Oncorhynchus mykiss, in the Columbia Basin Abstract -- The species Oncorhynchus mykiss expresses a complex array of life histories across much of its range as well as considerable geographic variation. Several subspecies have been proposed (Behnke 1992), although none of them are formally recognized. Two of the proposed subspecies in North America include both trout and steelhead life histories: O.m. irideus, or Coastal rainbow/steelhead, and O.m. gairdneri, or Inland redband/steelhead. A third subspecies that includes an anadromous life history occurs in Asia, while all other North American subspecies are entirely trout. In the Pacific Northwest, the boundary between the coastal and inland subspecies occurs in the Columbia Gorge, where the Columbia River cuts through the Cascade Mountain Range. The steelhead and trout life histories within these two subspecies are genetically more similar to each other than to fish with the same life history in the other subspecies, indicating that the different life histories within a geographic area share an evolutionary origin (Allendorf 1975). Recent molecular systematic surveys suggest that this proposed taxonomic model of North American 0. mykiss subspecies may be over simplified and inaccurate (Currens 1997, Busby et al. 1996, F. Utter, U. of Washington); however, it remains the available model until final revisions to the taxonomy are adopted. The NOAA Fisheries Service (NMFS) further divided 0. mykiss into multiple "Evolutionarily Significant Units" (ESUs)(Waples 1991, 56 FR 58612, Waples 1995) for listing consideration under the federal Endangered Species Act (ESA). The ESA considers "distinct" populations of taxonmnic species to be "species" eligible for legal protection (16 U.S.C. 1532[161). NMFS adopted the concept of ESUs to serve as distinct population segments in their ESA listing decisions, along with specific criteria for defining them. Evidence for whether or not rainbow trout and steelhead are in the same ESUs is presented in this report according to the criteria provided by NMFS policy (56 FR 58612). The U.S. Fish and Wildlife Service (USFWS) likewise recognizes "Distinct Population Segments" (DPSs) that may be listed under ESA. The agencies share jurisdiction over 0. mykiss for ESA decisions, with NMFS overseeing the anadromous steelhead and USFWS overseeing the freshwater trout. NMFS has described ESUs for all Northwest steelhead, whether they have been listed or not (Busby et al. 1996); however, the USFWS has not generally described DPSs for Northwest 0. mykiss trout. During the original coast-wide status review of steelhead conducted in the 1990s, the NMFS Biological Review Team concluded that, in general, 0. mykiss trout are part of steelhead ESUs in cases where the two forms are sympatric and have an opportunity to interbreed (Busby et al. 1996). The review team was less conclusive about whether trout above artificial barriers were part of the ESUs. Trout that are sympatric with steelhead were also included in the ESUs by NMFS in the final listing determinations, but they were not listed. The steelhead in five of the ESUs in the Pacific Northwest were listed, including the Lower Columbia (63 FR 13347), Willamette, Mid-Columbia (64 FR 14517), Upper Columbia and Snake ESUs (62 FR 43937), all of which are in the Columbia Basin. As a result of two recent court cases NMFS is now reexamming the biological relationship between trout and steelhead populations in the ESUs where steelhead are listed and is reassessing the extinction risk of the whole ESUs from the perspective of both life histories. First, the Hogan decision in Oregon concluded that the Services may describe distinct population segments for ESA listing, but once ESUs or DPSs are described, the Services cannot list only part of one of one of them (Alsea Valley Alliance v. Evans [161 F.Supp. 2d 1154, D. Oreg. 2001]). So if NMFS finds trout to be part of an ESU along with steelhead, the Service cannot assess the extinction risk of only the steelhead in the ESU or list only the steelhead. Second, lawsuits in California about non­anadromous 0. mykiss upstream of man-made barriers (mostly impassible dams) made a similar argument, stating that such populations are related to the steelhead populations below the barriers and should be included in the ESUs and listed (EDC v. Evans, SACV- 00-1212-AHS (EEA), United States District Court, C.D. California). The purpose of this report is to provide more detailed information about trout and steelhead in the Columbia Basin listed ESUs. This report will address two major issues. The first section provides information that will be used to review whether trout and steelhead populations are biologically part the same ESUs, as defined by NMFS criteria. The second section provides information that will be used to review the extinction risks of entire ESUs if trout are considered along with steelhead. A similar, separate report is being prepared for California ESUs where steelhead are listed.

  Citation × Citation Citation Abstract Copy Title: AI - Stream Habitat Conditions on Industrial Forest Lands in Coastal Oregon Abstract -- In the summer of 1998 and 1999, watersheds in western Oregon were randomly sampled for stream habitat conditions. Sites were selected using a random tessellation stratified design. Oregon Department of Fish and Wildlife Aquatic Inventories methods were used to quantify indicators of sediment supply and quality, riparian forest connectivity and health, habitat structure, in-stream complexity, and presence of salmonid species. As part of the overall sampling 47 sites in 1998 and 70 sites in 1999 were sampled on industrial forest lands. Of these sites 13 were sampled both in 1998 and 1999, and 37 sites were sampled for fish presence/absence. Approximately 44% of the sites sampled for habitat were within the range of anadromous salmonids. Upstream catchment area and gradient were the two major factors driving the overall patterns of habitat variables. Secondarily, land ownership and geology were other factors correlated with the habitat variables analyzed. The private non-industrial land ownership type was characterized by slightly higher fine sediment levels, lower wood volumes and number of key wood pieces, lower densities of deep pools, and lower levels of stream shading. State and industrial forest lands show moderate wood levels in the stream channel, although they show low levels of conifers in riparian zones. The sedimentary geologic type was characterized by higher levels of fine sediments in riffle units. Twelve, high quality, unconstrained stream reaches occurred in the 1998 and 1999 habitat sample on Industrial forest lands. Conditions on industrial forest lands in 1998-1999 were compared to conditions in 1993-1994 to detect any potential change over the five-year period. Three different datasets were analyzed. No significant changes in aquatic habitat or riparian conditions were detected. Electrofishing surveys were conducted at 37 sites outside or the expected range of coho salmon to determine fish presence/absence. Salmonid species were present at 19 of the sites that were electrofished.

  Citation × Citation Citation Abstract Copy Title: Yachats River Basin Fish Management Plan 1997 Abstract -- The Yachats 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 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.

  Citation × Citation Citation Abstract Copy Title: Escapement and Productivity of Summer Steelhead and Spring Chinook Salmon in the John Day River; Annual Report 2017 Abstract -- The John Day River, located in northeastern Oregon, supports five wild populations of summer steelhead (Oncorhynchus mykiss) and three populations of wild spring chinook (Oncorhynchus tschawytscha) with no hatchery supplementation. However, these populations remain depressed relative to historic levels. In 1999, the National Marine Fisheries Service (NMFS) listed the Middle Columbia River summer steelhead Distinct Population Segment (DPS), which includes the John Day River Major Population Group (MPG), as threatened under the Endangered Species Act (ESA). Although numerous habitat protection and rehabilitation projects have been implemented within the John Day River basin to improve steelhead and other salmonid freshwater production and survival, it has been difficult to estimate the effectiveness of these projects without a systematic program in place to collect information on the status, trends, and distribution of spawning activity, juvenile salmonids, and aquatic habitat conditions within the basin. Prior to the inception of this project, population and environmental monitoring of steelhead in the basin consisted of a combination of index spawning surveys and periodic monitoring of some status and trend indicators. While index spawning data is useful for drawing inference about long-term trends in adult steelhead abundance, they are limited for determining the status of steelhead escapement or distribution at the population or MPG scale because survey sites are not randomly selected and are likely biased towards streams with higher fish abundance. A broader approach to the monitoring and evaluation of status and trends in anadromous and resident salmonid populations and their habitats was needed to provide data to effectively support restoration efforts and guide alternative future management actions in the basin. The Independent Scientific Review Panel (ISRP) recommended that the region move away from index surveys and embrace probabilistic sampling for most population and habitat monitoring. To meet the ISRP recommendation, the structure and methods employed by the Oregon Plan for Salmon and Watersheds Monitoring Program were extended to the John Day basin. This approach incorporates the sampling strategy of the United States Environmental Protection Agency’s (EPA) Environmental Monitoring and Assessment Program (EMAP). This research effort employs a statistically based and spatially explicit sampling design to answer key monitoring questions, integrate on-going sampling efforts, and improve agency coordination. The current program seeks to integrate project objectives focused on summer steelhead spawning metrics, juvenile salmonid metrics, and aquatic habitat conditions.

  Citation × Citation Citation Abstract Copy Title: Oregon Fish Habitat Distribution - Redband Trout Abstract -- These data describe areas of suitable habitat believed to be used currently and historically by redband trout populations. Columbia River redband trout, Oncorhynchus mykiss gairdneri, a subspecies of rainbow trout, Oncorhynchus mykiss, is native to the Fraser and Columbia River drainages, east of the Cascade Mountains to barrier falls on the Pend Oreille, Spokane, Snake and Kootenai rivers (Allendorf et al. 1980; Behnke 1992). Northern Great Basin redband trout, Oncorhynchus mykiss newberrii, are found in the closed basins of south-central Oregon as well as the Upper Klamath Lake basin. While Upper Klamath Lake now drains to the ocean, redband trout in the basin had ancestors that came from interior connections to the Great Basin and not from connections to the ocean (Behnke 1992). Redband trout, for the purposes of habitat distribution mapping, are generally defined as stream-resident O. mykiss gairdneri; migration is confined within their natal stream or watershed while steelhead, or the anadromous life form of O.mykiss gairdneri, migrate from their natal stream to the ocean and back. It is recognized, that while redband and steelhead habitat distribution datasets are published separately, overlapping areas represent the same subspecies. The term "currently" is defined as within the past five reproductive cycles.

The data are made available as GIS files in both shapefile and ESRI geodatabase format. The data were developed over an extensive time period ranging from 1996 to 2011. Title: Oregon Fish Habitat Distribution - Redband Trout Abstract -- These data describe areas of suitable habitat believed to be used currently and historically by redband trout populations. Columbia River redband trout, Oncorhynchus mykiss gairdneri, a subspecies of rainbow trout, Oncorhynchus mykiss, is native to the Fraser and Columbia River drainages, east of the Cascade Mountains to barrier falls on the Pend Oreille, Spokane, Snake and Kootenai rivers (Allendorf et al. 1980; Behnke 1992). Northern Great Basin redband trout, Oncorhynchus mykiss newberrii, are found in the closed basins of south-central Oregon as well as the Upper Klamath Lake basin. While Upper Klamath Lake now drains to the ocean, redband trout in the basin had ancestors that came from interior connections to the Great Basin and not from connections to the ocean (Behnke 1992). Redband trout, for the purposes of habitat distribution mapping, are generally defined as stream-resident O. mykiss gairdneri; migration is confined within their natal stream or watershed while steelhead, or the anadromous life form of O.mykiss gairdneri, migrate from their natal stream to the ocean and back. It is recognized, that while redband and steelhead habitat distribution datasets are published separately, overlapping areas represent the same subspecies. The term "currently" is defined as within the past five reproductive cycles. This information is based on sampling, the best professional opinion of Oregon Dept. of Fish and Wildlife or other natural resources agency staff biologists or modeling (see the fhdBasis field). Due to natural variations in run size, water conditions, or other environmental factors, some habitats identified may not be used annually. These data now comply with the Oregon Fish Habitat Distribution Data Standard that was adopted by the Oregon Geographic Information Council in February 2011.

These data describe areas of suitable habitat currently and historically used by Pacific lamprey populations. Pacific lamprey, Lampetra tridentata, (more recently identified as Entosphenus tridentatus), are native to the Pacific coast from Baja California to the Bering Sea. They are anadromous, migrating from their natal stream to the ocean and back, but unlike salmon, Pacific lamprey spend well over half of their total life cycle in freshwater. The Pacific lamprey was listed as an Oregon State sensitive species in 1993 and in 1996 was protected through restriction of harvest (ODFW 2006). These data now comply with the Oregon Fish Habitat Distribution Data Standard that was adopted by the Oregon Geographic Information Council in February 2011.

  Citation × Citation Citation Abstract Copy Title: Steelhead Escapement Monitoring In the Upper Grande Ronde River - Annual Technical Report 2011 Abstract -- The UGRR basin supports a population of summer steelhead that has been segregated from three other populations in the entire Grande Ronde River basin based on topographic, genetic, observational, and other evidence of interactions. Historically, the Grande Ronde River was one of the more significant anadromous fish producing rivers in the Columbia River Basin. Summer steelhead in the Grande Ronde River basin compose part of the Snake River Distinct Population Segment (DPS) and are listed as threatened under the Endangered Species Act (62 FR 43937; August 18,1997). Despite recovery efforts, these populations remain depressed relative to historic levels. This project annually evaluates summer steelhead population abundance for the UGRR by conducting surveys of redds and spawning activity. These surveys provide the data needed to estimate adult steelhead escapement, improve our understanding of habitat utilization, and contribute to productivity and survival estimates for this population. Steelhead were monitored using a probabilistic sampling approach that incorporates a sample-site selection procedure created for the Environmental Protection Agency’s environmental monitoring and assessment program (EMAP). We used this EMAP design to select sample sites for status and trend monitoring of steelhead redds within the UGRR watershed. This method allowed us to sample spatially balanced survey sites distributed within the basin, and followed the Oregon Plan for Salmon and Watersheds Monitoring Program approach (Stevens 2002).
