These surveys were commissioned by the Midcoast Watershed Council, using funds granted by GWEB. The intent of these surveys was to begin to develop a base line for monitoring trends in the distribution and abundance of juvenile Coho, Steelhead and Cutthroat in Midcoast watersheds. Adult Coho escapement for many of these basins has hovered near all time low levels for multiple brood cycles. These surveys intend to identify the core areas within these basins that, at low spawner densities, provide suitable spawning habitats. They also intend to identify areas important for juvenile salmonid rearing such that restoration activities can focus on recovering reaches that adult salmonids are returning to.

  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: Work Completed for Compliance with the Biological Opinion for Hatchery Programs in the Willamette Basin USACE funding: 2004 Annual Report Abstract -- The National Marine Fisheries Service (NMFS) has listed spring chinook salmon(Oncorhynchus tshawytscha) and winter steelhead (O. mykiss) in the Upper Willamette River Evolutionarily Significant Unit (ESU) as threatened under the Endangered Species Act (ESA; 64 FRN 14308; 64 FRN 14517). Concomitant with this listing, any actions taken or funded by a federal agency must be evaluated to assess whether these actions are likely to jeopardize the continued existence of threatened and endangered species, or result in the destruction or impairment of critical habitat. Several fish hatcheries operate within the ESU and may impact wild populations of listed species. Although all of the artificial propagation programs that potentially affect listed salmonids in the Upper Willamette River ESUs are operated by the Oregon Department of Fish and Wildlife(ODFW), 90% of the funding for these operations comes from the U.S. Army Corps of Engineers (COE). Possible risks of artificial propagation programs have been well documented. Hazards include disease transfer, competition for food and spawning sites, increased predation,increased incidental mortality from harvest, loss of genetic variability, genetic drift, and domestication (Steward and Bjornn 1990; Hard et al. 1992; Cuenco et al. 1993; Busack and Currens 1995; NRC 1996; and Waples 1999). Hatcheries can also play a positive role for wild salmonids by bolstering populations, especially those on the verge of extirpation, providing a genetic reserve in the case of extirpation, and providing opportunities for nutrient enrichment of streams (Steward and Bjornn 1990; Cuenco et al. 1993). The objective of this project is to evaluate the potential effects of hatchery programs on naturally spawning populations of spring chinook and winter steelhead within the Upper Willamette River ESU. The project employs four types of activities to achieve this goal: sampling of returns to hatcheries, creels to assess fisheries, monitoring of adult and juvenile migration through the use of traps and video observations, and monitoring natural production through spawning ground surveys.

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.

Tide gates are tidal flood control structures designed to open and close with each tidal cycle to limit tidal influence on upstream agricultural areas. The basic function of tide gates creates a partial barrier to fish passage. Coastal lowland streams are critical for the sustainability of Oregon Coastal coho, but it is unclear how tide gates may affect coho movement, habitat use and survival.

The basis of these estimates are visual counts of adult spawners in randomly selected stream reaches. To date, survey-derived estimates have not been validated against known spawner abundances. Beginning in 1999, we initiated a study at Smith River (Umpqua Basin) to calibrate survey-based spawner estimates. Smith River provides an ideal location for this type of study because it is typical of many other coastal streams that support coho salmon, contains large quantities of habitat and spawners, and provides the ability to efficiently trap and tag adequate portions of the coho run.

  Citation × Citation Citation Abstract Copy Title: OASIS - Use of Stratified Random Sampling to Estimate the Abundance of Oregon Coastal Coho Salmon Abstract -- Management of coho salmon (Oncorhynchus kisutch) in Oregon is heavily dependent upon estimates of the spawning escapement of Oregon coastal natural OCN) coho salmon. OCN coho salmon consist of an aggregate of wild coho salmon populations that originate from Oregon coastal river basins south of the Columbia River and north of Cape Blanco. OCN spawning escapement estimates are an integral component of the management of salmon fisheries in the ocean. Escapement estimates are also used to assess progress towards meeting goals addressed in Oregon's Coho Salmon Plan (ODFW 1982), the Salmon Framework Plan of the Pacific Fisheries Management Council (PFMC 1984), the Oregon Department of Fish and Wildlife (ODFW) Wild Fish Policy, the Oregon Salmon Restoration Plan (Oregon 1997) and various management plans for coastal basins. During 1985-86, the Oregon State University Department of Statistics was contracted by ODFW to review the method used to estimate OCN spawning escapement and to recommend procedures for improving the methodology (Ganio et al.1986). Five sources of bias were identified in the methodology: (1) methods of survey site selection, (2) estimates of the life span of fish in survey sites, (3) counting of nonspawning fish in survey sites, (4) under-counting of fish in survey sites, and (5)estimates of total miles of spawning habitat. The authors concluded that the method of survey site selection was probably the most serious source of bias because of evidence that survey sites were predominantly located in "better than average" spawning habitat. To improve the methodology used to estimate OCN escapement, the authors proposed a sampling plan designed to reduce survey site selection bias and to provide an estimate of the precision of the escapement estimate. The recommended sampling plan incorporated a stratified random sampling (SRS) scheme, where, within geographic 2 sampling units, survey sites are randomly selected from the estimated available miles of coho salmon spawning habitat. Although the SRS survey procedure proposed by Ganio et al. (1986) was a means of vastly improving OCN escapement estimates, more information was needed before this procedure could be adopted. Procedures needed to be developed for selecting and surveying random survey sites (Ganio et al. 1986). The feasibility of incorporating additional levels of stratification to improve the efficiency of the sampling program and account for additional escapement resulting from hatchery fish was needed. More accurate estimates of the available spawning habitat for coho salmon in coastal watersheds were necessary for the development of an effective SRS scheme and ultimately, as a means of improving absolute escapement estimates. Finally, the relationship between spawning densities estimated from the standard coho salmon survey program and spawning densities estimated from a SRS program needed to be determined.

Abstract -- This report provides an assessment of abundance, distribution, spawn timing, and hatchery:wild ratios of spawning adult coho salmon (Oncorhynchus kisutch) based on EMAP spawning surveys in the Oregon portion of the Lower Columbia River in the 2002, 2003, and 2004 spawning seasons. The Oregon portion of the Lower Columbia River Evolutionarily Significant Unit (ESU) extends from the mouth of the Columbia River to the Hood River, excluding areas above Willamette Falls. Analysis is conducted at the population complex level, six subsets of the ESU defined during Oregon Department of Fish and Wildlife Status Review (Chilcote 1999). Population characteristics, most notably the proportion of wild spawners and spawn timing, vary among complexes. Interannual variation within complexes over the last three years is linked to streamflow variation. Most hatchery straying occurred within complex, though the Bonneville complex received strays from further upriver. Abundance increased in areas without evidence of hatchery inputs. Abundance goals established by the ODFW endangered species management plan (Chilcote 2001) in the Clackamas (>1900 adults) and Sandy (>670 adults) have been met the last two years; however, spawner densities and the proportion of wild spawners are lower than on the Oregon Coast.

Seines and a rotary screw trap were used to capture fish for dye-marking, and residence time within the ecotone was determined for recaptured marked fish. In the lower estuary, ultrasonic transmitters were used to document residence time and patterns of movement for smolts migrating to the ocean. Nearly half of each brood year moved to the estuary as subyearlings. A portion of age-0 juveniles that moved downstream during spring lived in the ecotone through summer for up to 8 months, then most moved back upstream to overwinter. Fish that moved to the ecotone during fall and winter had mean minimum residence times of 48 d in 1999 and 64 d in 2000. Some of the fish that moved to the ecotone during fall and winter moved into an off-channel beaver pond and resided there for a mean of 49 d. Spring age-1 smolts had a mean minimum residence time in the ecotone of 18 d for both years and used recently restored salt marshes and other off-channel habitats. Smolts implanted with ultrasonic transmitters lived in the lower estuary for an average of 5.8 d, during which their direction of movement corresponded to the direction of tidal flow.

Contributions included increased nutrient input to the ecosystem and an additional food source for predators, including bull trout. In addition, the progeny of these adult salmon provided a landlocked chinook fishery in the reservoir and ODFW was able to discontinue annual releases of juvenile salmon reared in ODFW hatcheries (1996). ODFW assumed most of the salmon attempting to leave the reservoir would be killed by various means upon passage through the turbines or regulating outlet. Between 1994-97, ODFW field observations provided circumstantial evidence that some juvenile chinook were surviving passage through the dam. In 1998, we began monitoring juvenile chinook migration out of the reservoir to determine the number, size, age, and mortality rate of fish passing through the turbines and regulating outlet of Cougar Dam.

  Citation × Citation Citation Abstract Copy Title: AI - Rearing of Juvenile Salmon in Recovering Wetlands of the Salmon River Estuary Abstract -- The Salmon River estuary, on the central Oregon coast, provides an excellent opportunity to study salmonid use of restored tidal marsh. The U.S. Forest Service manages the estuary as part of the Cascade Head Scenic Research Area with the goal to rehabilitate the estuary “to its condition prior to the existing diking and agricultural use.” To achieve this goal, the U.S. Forest Service has completed three dike removal projects at 9-year intervals beginning in 1978. These projects created a patchwork of restored marshes in various stages of recovery, providing a natural laboratory for studying marsh restoration processes and their effects on estuarine rearing salmonids. Our Sea Grant-funded research, which is a cooperative study with researchers from the University of Washington, has four objectives: (1) describe salmon species use of undiked reference and recovering marshes; (2) compare diets of juvenile salmon among reference and diked marshes of different recovery ages; (3) compare availability and distribution of prey organisms consumed by juvenile salmon; and (4) assess geomorphological and ecological indicators (“metrics”) of restored wetlands and relationships to salmon use. This report describes the results of fish distribution and abundance surveys. Results of the other objectives are described in Gray et al. (In Review).

This program functions as the landscape link in the overall Oregon Plan monitoring program. Field work for the habitat monitoring program began in 1998 with coordinated site visitations conducted with the two other Oregon Plan monitoring programs; juvenile rearing survey and adult salmon spawning survey programs. The Oregon Plan Habitat Survey program is nested within the Aquatic Inventories Project (AIP). The AIP was begun by the Oregon Department of Fish and Wildlife (ODFW) in 1990 and has expanded to include a wide variety of inventory, modeling and monitoring efforts. The central purpose of these diverse projects is the inventory of physical aspects of the environment that are important for aquatic life and the habitat needs of salmonids and other fishes during the freshwater stages of their life history. Some of the significant ongoing or recently completed projects that are part of the AIP are: Basinwide cesus surveys, Oregon plan Habitat surveys, Restoration Project Monitoring, Salmonid Habitat and Diversity Watersheds Project, Fish Inventories, Great Basin Redband Trout, Oregon Chub Status and Recovery Project, Salmon River Estuary, and Columbia River Estuary Project.

  Citation × Citation Citation Abstract Copy Title: AI - Oregon Coast Coho Assessment: Habitat Abstract -- In November 2003, the State of Oregon began a comprehensive review of coho and their habitat in NOAA Fisheries’ Oregon Coastal coho Evolutionary Significant Unit (ESU). The purpose of the review is threefold: 1) provide an analysis of the current status and trend in coho populations, their habitat, and related threats; 2) provide NOAA Fisheries with information it requires to determine whether formalized conservation efforts within the ESU justify not listing coho under the Endangered Species Act as outlined in their Policy for Evaluation of Conservation Efforts; and 3) provide information to state agencies, watershed councils, and others participating in the Oregon Plan for and Watersheds (OPSW) so they may assess the success of their OPSW programs and modify them where necessary to better achieve their objectives (i.e. adaptive management). This report describes the current status and trend of instream physical habitat for coho in the ESU as well as summarizes and evaluates instream habitat restoration activities conducted from 1997-2003. Persistence of coho salmon populations in coastal drainages during periods of poor ocean conditions is dependent on the distribution and carrying capacity of freshwater habitat. Coho salmon are sensitive to the quality of habitat during each life stage and seasonal effects on survival are propagated through subsequent life stages (Nickelson et al. 1992). In this chapter, we use measures of habitat quality and quantity to determine overall carrying capacity of freshwater habitat at two juvenile coho life stages: 1) fry through summer parr; and 2) over-winter parr to smolt. From this information we identify life stages at which habitat may limit the coho smolt production capacity for the coho salmon populations considered independent by NOAA Fisheries Technical Recovery Team.

  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.

The structure and complexity of the stream habitat influences the species composition, distribution, and production of the fish community. Assessing the status of stream habitat conditions in coastal Oregon streams is important for monitoring the effects of landscape and aquatic management practices on the character of riparian stream habitat. Comprehensive habitat assessments are also important for watershed assessments, restoration planning, and for studying the relationship between stream habitat, fish abundance, and fish distribution. The goals of the Oregon Plan for Salmon and Watersheds (OPSW) Habitat Monitoring Program are to 1) provide an annual update on the status of stream habitat in Western Oregon, and 2) track trends in habitat over time.

The goal of these surveys is to document the status and trends of stream conditions that exist in coastal drainages of western Oregon. To better interpret landscape patterns in aquatic habitat character, the Aquatic Inventories Project has sought to improve the definition of a set of reference conditions from which to compare habitat survey sites. Over the past three years, the set of reference conditions used in analyses was selected from basin-wide habitat surveys conducted between 1992 and 1997. These conditions did not adequately represent the variety of stream sizes, geologic types, or ecoregions present in all coastal streams. The Aquatic Inventories Project selected a set of new reference survey locations that better represent reference conditions in coastal streams for a variety of ecoregions, geologic types, and basins. The reference sites selected for the year 2000 represented watershed areas with low impact from human activities such as roads, development, and forest management. Ideally, areas would have been selected that were completely free from human disturbance, but we concluded it was more important to represent a larger geographic range of conditions across the landscape.
