This report also includes updates to long-term status and trend data for the ESA-listed Umatilla steelhead population, which is a large population within the Umatilla/Walla Walla Major Population Group. The project used two fixed site traps, PIT tags, and mark-recapture to assess the status and trend of juvenile abundance and productivity, estimate survival rates, and monitor life history characteristics. Spatial distribution and density of summer steelhead redds were determined using a spatially balanced random sample (Generalized Random Tessellation Stratified) within a temporally based panel design. Redd distribution data was collected from 25–35 individual sites.

To meet the ISRP’s recommendation, we extended the structure and methods employed by the Oregon Plan for Salmon and Watersheds Monitoring Program to the John Day subbasin. This approach incorporates the sampling strategy of the U.S. Environmental Protection Agency’s (EPA’s) Environmental Monitoring and Assessment Program (EMAP). The EMAP is a long-term research effort with a statistically based and spatially explicit sampling design. This program, successfully implemented in Oregon’s coastal watersheds, applies a rigorous, Tier-2 sampling design to answer key monitoring questions, integrate on-going sampling efforts, and improve agency coordination. The objectives of this project are to determine annual estimates of steelhead spawner escapement, juvenile salmonid rearing distributions, physical habitat conditions, smolt-to-adult survival rates (SAR), and track changes in the status and trends of these estimates over time. We began to meet these objectives in 2004 through spawning ground surveys initiated in spring and juvenile salmonid and habitat surveys during summer. In addition, data from on-going projects in the basin, such as smolt and adult monitoring, will be incorporated in future years to develop a more complete picture of status and trends in resources and life-stage specific survival not targeted under the EMAP program. We believe this project will be the vehicle to synthesize all related fish population and habitat monitoring data at the provincial and subbasin scales.

In 1998, the Oregon Department of Fish and Wildlife (ODFW) implemented a monitoring program that utilized a random, spatially balanced survey design to provide statistically rigorous information on the status and trend of habitat conditions in Oregon coastal streams. In response to the ESA listing of coho salmon, the State of Oregon published a comprehensive review of aquatic habitat in the Oregon Coastal Coho Evolutionary Significant Unit (ESU) in 2005 (Rodgers et al 2005). The NOAA Fisheries more recently published a request for additional information in the 2009 Federal Register notice (Federal Register / Vol. 74, No. 81 / Wednesday, April 29, 2009). This report will serve as an update to Rodgers et al (2005), and will provide an analysis of the current status and trends in aquatic habitat from 1998 through 2008 within the Oregon Coastal Coho ESU. The status and trend of instream physical habitat conditions in the Oregon Coastal coho ESU were assessed from twelve variables collected by the ODFW habitat monitoring program from 1998-2008. Habitat conditions were described at the scale of the ESU, four monitoring areas/strata within the ESU, and by six land use categories (agriculture, urban, private non-industrial and industrial forest, and public state and federal forest). The condition of habitat was compared among monitoring areas and land use categories. In addition, the habitat condition at random survey sites was compared to that at sites experiencing minimal human disturbance (i.e. reference sites). Potential winter rearing capacity for juvenile coho salmon was calculated for all available habitat and for high quality habitat at the monitoring area scale and in selected population units. We calculated the rearing potential from high quality habitat because modeling (Nickelson and Lawson 1998) demonstrated that during periods of prolonged poor ocean survival, only areas with high quality habitat will be able to support coho at full seeding during poor marine conditions. The final objective of this report is to discuss whether sufficient habitat capacity exists to support productivity of juvenile coho at the monitoring strata scale during periods of low marine survival.

  Citation × Citation Citation Abstract Copy Title: Upper Sprague Watershed Assessment Abstract -- The insight that soil, water and vegetation interact dynamically to produce watershed conditions has led to two principles that have informed the content of this document. First is the importance of basing our restoration and/or our management planning on site-specific conditions, rather than on generalized judgments about conditions at the watershed scale. While watershed-scale statements and analyses are very important for context and for the “big picture,” any actual on-the-ground actions must be rooted in analysis of the actual conditions on the site in question. Second is the importance of focusing on “trend over time,” rather than on static “snapshots” of watershed conditions. The snapshot approach to assessment of conditions compels the analyst or resource manager to make “black or white” determinations about whether or not a given site is acceptable. Focusing on trend over time, on the other hand, allows the resource managers to determine whether fundamental processes are in place that will produce a stable -- but dynamic -- landscape over the long term.

  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.

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. Close

  Citation × Citation Citation Abstract Copy Title: 2017 Bull Trout Redd Monitoring in the Wallowa Mountains Abstract -- Bull trout were listed as threatened under the Endangered Species Act in 1998 due to declining populations. The U. S. Fish and Wildlife Service (Service) recommends monitoring bull trout in subbasins where little is known about the populations, including the Grande Ronde and Imnaha subbasins. Spawning survey data is important for determining relative abundance and distribution trends in bull trout populations. This report summarizes the 2017 bull trout spawning data collected in the Wallowa Mountains of northeast Oregon and compares this with past years’ data. Bull trout spawning surveys have been conducted on similar index areas for selected Grande Ronde and Imnaha River streams from 1999 to 2017. These surveyed streams are located within the Wallowa River/Minam River and Imnaha River bull trout core areas. Surveys in 2017 were conducted by the Nez Perce Tribe (NPT), the Oregon Department of Fish and Wildlife (ODFW), the Service, U.S. Forest Service (USFS), Freshwater Trust, and fisheries consultants. Objectives of the survey included: (1) locate bull trout spawning areas; (2) determine redd characteristics; (3) determine bull trout timing of spawning; (4) collect spawning density data; (5) determine and compare the spatial distribution of redds along the Lostine River in 2006 through 2017; and (6) over time use all of the data to assess local bull trout population trends and the long-term recovery of bull trout. Timing of spawning, total redds, redd sizes, and redd locations are documented in the report.

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: Abundance Monitoring of Juvenile Salmonids In Oregon Coastal and Lower Columbia Streams, 2007 Report Number: OPSW-ODFW-2008-1 Abstract -- As part of the Oregon Plan for Salmon and Watersheds, the Oregon Department of Fish and Wildlife (ODFW) initiated a project in 1998 to monitor the trend in abundance and distribution of juvenile coho salmon (Oncorhynchus kisutch) rearing in Oregon coastal streams. Monitoring is currently designed to provide annual abundance and distribution information at the stratum-scale (described in Jepsen and Leader 2007) for each of several coho evolutionarily significant units (ESU’s) and steelhead distinct population segments (DPS’s), and to eventually use these annual data to provide longterm trend information. Ultimately these juvenile fish data will be used to investigate relationships between freshwater habitat characteristics, adult spawner abundance, and juvenile recruitment. This progress report summarizes abundance and distribution data collected in 2007 for each ESU and DPS, and for the Oregon Coast Coho ESU includes a time series for abundance data for all years of monitoring. A fuller description of the OCC, OCS, SONCC and KMPS sampling frames, study design and survey methods, is found in Jepsen and Rodgers (2004) and for the LCRC and LCRS frames in Jepsen and Leader (2007). The strata are diagramed in Figure 1 and organized in subsequent tables. At a subset of the OCC sites, this project also collects water temperature data and macroinvertebrate data in conjunction with Oregon Department of Environmental Quality. These data will be reported separately, and can be requested from project staff. In addition, the project re-initiated a snorkel and electrofishing verification study in the Smith River basin, which will be summarized in a separate report.

To aid juvenile salmonid downstream passage through LOP Reservoir and dam, the USACE is examining several reservoir drawdown scenarios. The main objective of this study is to provide baseline (pre-drawdown) data on relative abundance, size, and distribution of predators (northern pikeminnow, walleye, largemouth bass, and crappie) in LOP Reservoir to help assess the effect of a possible LOP drawdown or similar operations. Results of this work are provided in the first section of this report. In the second section, we provide results from a radio-telemetry study on the movement and distribution of northern pikeminnow tagged in the reservoir.

  Citation × Citation Citation Abstract Copy Title: Steelhead Escapement and Juvenile Production Monitoring in the John Day Basin - Annual Technical Report 2011 Abstract -- The Independent Scientific Review Panel (ISRP), in their guidance on monitoring, strongly recommended that the region move away from index surveys and embrace probabilistic sampling for most population and habitat monitoring. To meet the ISRP’s 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 U.S. Environmental Protection Agency’s (EPA’s) Environmental Monitoring and Assessment Program (EMAP). The EMAP is a long-term research effort with a statistically based and spatially explicit sampling design. This program applies a rigorous, Tier-2 sampling design to answer key monitoring questions, integrate on-going sampling efforts, and improve agency coordination. EMAP objectives specific to the John Day basin are to determine annual estimates of steelhead spawner escapement, hatchery to wild steelhead stray ratios, juvenile steelhead and other salmonid rearing distributions, physical habitat conditions, and track changes in the status and trends of these estimates over time. In addition, data from on-going projects in the basin, such as smolt monitoring, will be incorporated in future years to develop a more complete picture of status and trends in resources (e.g. life-stage specific survival) not targeted under the EMAP program. This project provides information as directed under two measures of the Columbia Basin Fish and Wildlife Program. Measure 4.3C specifies that key indicator naturally spawning populations should be monitored to provide detailed stock status information. In addition, measure 7.1C identifies the need for collection of population status, life history, and other data on wild and naturally spawning populations. This project was developed in direct response to the recommendations and needs of regional modeling efforts, the ISRP, the Fish and Wildlife Program, the Oregon Plan for Salmon and Watersheds, and the Columbia Basin Fish and Wildlife Authority Multi-Year Implementation Plan.

Results from this year are compared with our findings from 1998 – 2012. This unique, long term data set is used to monitor and describe trends in juvenile salmonid distribution and abundance for the three coho Evolutionarily Significant Units (ESU) and the four steelhead Distinct Population Segments (DPS) in coastal Oregon. Full reports from prior years are available at: https://nrimp.dfw.state.or.us/crl/default.aspx?pn=WORP. Oregon Coast Coho (OCC) ESU juvenile density estimates in 2013 were higher than any other year. The site occupancy rate in 2013 was similar to 2012. The latest three cohorts had the 1st, 3rd, and 2nd highest occupancy rates estimated over the duration of the project. Pool population estimates in 2013 were similar to 2012 and to the average of the last three cohorts. Overall, we observed a small, positive trend in occupancy and pool population estimates across the ESU from 1998-2013. In the Oregon Coast Coho ESU plots of parr abundance with female spawner abundance suggest limits to parr production in freshwater habitats. Southern Oregon Northern California Coho (SONCC) ESU juvenile density estimates were similar to 2012 and to the average since 1998. Site occupancy was higher in 2013 than in 2012 but these estimates were the two lowest observed. Pool population estimates were similar to 2012, but lower than in most years, with the exclusion of the 1998-2000 estimates. Regressions of both site occupancy and pool population estimates to survey year do not show detectable trend since the start of monitoring in the ESU. Lower Columbia River Coho (LCR) density, site occupancy, and pool population estimates were similar to 2012 and to the average since 2006. Regressions of both site occupancy and pool population estimates to survey year do not show detectable trends since the start of monitoring in the ESU. The Oregon Coast Steelhead DPS density estimate in 2013 was higher than in 2012 and the average since 2002. Pool population estimates in 2013 were similar to 2012 and to the average. Site occupancy estimates from 2013 were similar to 2012 and the latest three years have had the three highest occupancy estimates. In the Klamath Mountain Province (KMP) DPS, steelhead density in 2013 was the lowest recorded and similar to the next lowest estimate in 2012. Pool population estimates were similar to the average and to 2012. Site occupancy was the third lowest estimate, and similar to the low in 2012. Steelhead density estimates in the LCR and the Southwest Washington (SWW) DPSs in 2013 were similar to each other, to average, and to the 2012 estimates. Site occupancies in the LCR and SWW were similar to 2012 and to the average estimates for the DPSs. Point estimates for site occupancy in SWW for the last two years have been the first and second highest recorded. Pool population estimates for both DPSs were similar to 2012 and to the average. Analyses which included shallow pools (below our former 40cm maximum depth criteria) produced higher site occupancies and larger pool population estimates with proportionately smaller confidence intervals. Population estimates that included shallow pools tracked with those based on the former pool criteria.

  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.

The ODFW Aquatic Inventories Project has conducted stream habitat surveys as part of its basin survey project and habitat assessment project under the Oregon Plan for Salmon and Watersheds. The goal of these surveys was to document the status and trends of stream conditions in coastal drainages. These surveys in conjunction with fish distribution, fish presence, potential barriers to passage, and past restoration activities will be the basis of the analyses.

This analysis was conducted by Siuslaw National Forest personnel with assistance from the Bureau of Land Management - Coos Bay District. The analysis was focused on fisheries and wildlife issues. The existing resource conditions were compared to expected natural conditions to assess trends in resource conditions. From this information, a strategy of restoration opportunities to enhance resource conditions on federal lands was developed. Watershed Analysis is one of the key components of the Aquatic Conservation Strategy (ACS) developed for the Northwest Forest Plan (NFP) (USDA-USDI 1994). The analysis is intended to facilitate watershed planning that: 1) achieves Aquatic Conservation Strategy and Late-Successional Reserve objectives and 2) provides the basis for monitoring and restoration programs.

The initial surveys were done on purposefully selected streams. The sampling design was switched to a stratified random probability design in 1990 (Urquhart and Kincaid, 1999). The current concern with long-term viability of coastal coho populations sparked a review of that design, with an objective of achieving an integrated sampling approach for spawning salmon, juvenile salmon, and freshwater physical habitat. For each for these populations, there was an interest not only in current status in terms of fish numbers or habitat quality, but also in regional temporal trends. In addition, the Oregon Department of Environmental Quality (DEQ) wanted a much smaller sample from the same stream population to measure water quality. The design discussed in this report addresses all of these objectives.

Distribution measures are given specific to species and include site occupancy (the percent of sites with fish present) and pool occupancy (average percent of pools with fish) for the Monitoring Area (MA), Evolutionarily Significant Unit (ESU) or Distinct Population Segment (DPS). Abundance measures are also specific to species and include the average density of fish in pools for each MA, ESU and DPS and population estimates in pools extrapolated to MA, ESU and DPS scale. Prior reports can be found at http://nrimp.dfw.state.or.us/crl/default.aspx?pn=WORP. Oregon Coast Coho (OCC) ESU density and pool population estimates for 2011 were higher than in 1998-2000, but similar to 2001-2010. Coho site occupancies in 2011 were the highest since sampling began in 1998. We observed a small, but positive trend in the site occupancy and pool population estimates for coho across the ESU from 1998 to 2011. Density and occupancy metrics were higher in each MA than the average condition from 1998 – 2010. Southern Oregon Northern California Coho (SONCC) ESU density estimates in 2011 were similar to 2009-2010, but lower than the estimate for 2008. Pool population estimates were similar to the average from 1998-2010, but lower than in 2008. Pool occupancy was similar to the average from 1998-2010. Site occupancy in 2011 was slightly below the average from 1998-2010. No increasing or decreasing trends were detected for the ESU. Lower Columbia River (LCR) coho density, pool population, and pool occupancy estimates for 2011 were similar to previous years. Site occupancy in 2011 was slightly below the average site occupancy from 2006 – 2010. No increasing or decreasing trends were detected for the ESU. Coho density estimates were higher in the OCC than the SONCC and the LCR, which were similar. Occupancy metrics were highest in the OCC, intermediate in the SONCC, and lowest in the LCR. Juvenile steelhead density, pool population and pool occupancy estimates from 2011 were comparable to previous years in all DPSs. Site occupancies for the Oregon Coast DPS in 2011 were the highest since sampling began. Steelhead were more abundant and widespread in the Klamath Mountains Province than the Oregon Coast, Southwest WA or Lower Columbia River DPSs, which had similar density metrics. Steelhead in the Oregon Coast DPS were more widespread then in either Columbia River DPSs. In accordance with the findings of the Smith River Verification Study (Constable and Suring in prep.) we lowered our pool depth criteria to include pools that are =20 cm in maximum depth. This change was made in survey year 2010 and continued in 2011. Data which included these smaller pools was analyzed separately to facilitate the comparison of density and occupancy metrics to previous years. Analyses which included smaller pools produced higher site occupancies for coho in the Mid Coast and Umpqua and for steelhead in the Mid Coast, Mid South Coast, Umpqua MAs and the Klamath Mountains and Southwest Washington DPSs. Pool population estimates also increased with the addition of the smaller pools.

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 - Restoration Effectiveness Monitoring Plan for the Western Oregon Stream Project; Monitoring through June 2008 Abstract -- The purpose of this plan is to outline the continued monitoring of stream restoration work completed as part of the Western Oregon Stream Project. This revised plan has been developed out of a need to monitor a subset of restoratio n projects from all areas of the Western Oregon Stream Project (Figure 1). This plan encompasses the monitoring period of January 2000 to June 2008, and is a continuation of monitoring activities that were started in the fall of 1995 on the North Coast and continued into the Mid-coast in 1996 and 1997. Much of this plan is a compilation of the original North Coast and Mid-Coast monitoring plans (Hodgson 1996, Thom and Moore 1995). Modifications have been made to better define the monitoring activities, increase efficiency, and strengthen the scientific credibility of the project. Four main questions will be answered as a result of the monitoring activities outlined in this plan. They are: 1)How much stream restoration work has been completed? 2)Is the stream restoration work that is completed leading to improved habitat conditions for salmonids in the treated stream reaches? 3)What fish are utilizing the restored habitats? 4)What are the trends in juvenile abundance in the restored stream reaches? Title: AI - Restoration Effectiveness Monitoring Plan for the Western Oregon Stream Project; Monitoring through June 2008 Abstract -- The purpose of this plan is to outline the continued monitoring of stream restoration work completed as part of the Western Oregon Stream Project. This revised plan has been developed out of a need to monitor a subset of restoratio n projects from all areas of the Western Oregon Stream Project (Figure 1). This plan encompasses the monitoring period of January 2000 to June 2008, and is a continuation of monitoring activities that were started in the fall of 1995 on the North Coast and continued into the Mid-coast in 1996 and 1997.

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. This report on stream habitat conditions covers sampling that occurred between June and October of 1999. The report is grouped into six different areas: • Current habitat status by Gene Conservation Area (GCA) • The status of habitat in relation to landscape variables • An assessment of the high quality habitat existing on the landscape • A comparison of 1998 and 1999 stream conditions • An analysis of habitat variable precision • An assessment of fish distribution outside of known coho salmon distribution Title: AI - Stream Habitat Conditions in Western Oregon, 1999 Abstract -- The physical habitat of a stream forms the template from which the biological community can develop.

  Citation × Citation Citation Abstract Copy Title: AI - Reference Site Selection and Survey Results 2000 Abstract -- The Oregon Department of Fish and Wildlife (ODFW) Aquatic Inventories Project conducts stream habitat surveys as part of the Oregon Plan for Salmon and Watersheds. 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.

The Bridge Creek watershed drains a total of 269 square miles and contains 69 miles of summer steelhead (Oncorhynchus mykiss) spawning habitat. Wheeler Soil and Water Conservation District (SWCD) staff surveyed 23.6 miles of the mainstem of Bridge Creek during the summer of 2013. The data from this survey was entered into a spatially referenced geodatabase of the stream channel. The purpose of this reach evaluation is to identify the severity of the limiting factors on a reach by reach basis and create an interactive GIS framework with the purpose of improving the effectiveness of restoration work conducted within the Bridge Creek watershed. Resource Specialists Inc. was commissioned to analyze the data and examine trends within the watershed. The results of the analysis are contained within this report. Steelhead are currently listed as a threatened species. The overall health of the steelhead population in the middle Columbia River along with limiting factors and guidelines for recovery were detailed in "Conservation and Recovery Plan for Oregon Steelhead Populations in the Middle Columbia River Steelhead Distinct Population Segment," henceforth referred to as the "Mid-C Recovery Plan."

The goals of this program were discussed by Dalton (1998). Briefly, we examine migration timing and abundance of the various species by size and/or age class. In the Tillamook Bay watershed, the Tillamook County Performance Partnership (TCCP) and the Oregon Department of Forestry (ODFW) have provided funding for monitoring in the Little North Fork (LNF) Wilson and Little South Fork (LSF) Kilchis rivers. Data collected during the 2001 trapping season and an annual report are presented for juvenile salmonid out-migrant trapping on the LNF Wilson and LSF Kilchis rivers. Juvenile chinook salmon numbers had decreased greatly each year from 1998 to 2000 in both rivers, but in 2001 this trend was reversed. Data is presented as tables and figures within the report.

This project is designed to assess the yearly status and trend, presence of hatchery fish, and distribution of winter steelhead spawners in six coastal Monitoring Areas (MA) in two Distinct Population Segments (DPS) (Figure 1). A spatially balanced probabilistic sampling design (Stevens 2002) was used to select survey sites across a stream network of winter steelhead spawning habitat. Monitoring of winter steelhead abundance is based on counts of redds instead of live or dead fish, in accordance with prior work conducted by ODFW in Oregon coastal streams (Susac and Jacobs 1999). Repeat visits to each site from February through May generated a total redd count for each survey. Redds were marked with colored rocks and flagging to prevent re-counting, during subsequent surveys. The survey interval of once every fourteen days is based on prior research (Susac and Jacobs 1999). Specific descriptions of project protocols can be found in the annual survey procedures manual (ODFW 2007). More information on methods and study background is available in Suring (In Prep.).

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.

Spawning survey data is important for determining relative abundance and distribution trends in bull trout populations. Without adequate funding, it has been difficult to find sufficient numbers of experienced bull trout surveyors and packers for surveys in the back-country, and to obtain adequate supplies to get the work accomplished. OWEB funding supported the continued survey of bull trout spawning areas in years 2016 through 2018 in the Grande Ronde and Imnaha drainages of northeast Oregon. Surveys were conducted by fisheries consultants, the Service, Nez Perce Tribe, the Oregon Department of Fish and Wildlife, U.S. Forest Service, Freshwater Trust, Wallowa Resources, Anderson Perry, Inc., Grande Ronde Model Watershed, and volunteers. Timing of spawning, total redds, redd sizes, and redd locations are documented in the attached report. In 2016-2018, surveys were located on the Lostine and Imnaha Rivers, and Big Sheep and Bear Creeks. In addition, the Upper Minam and Wenaha were surveyed in 2018.

Historically the Calapooia River marked the upper end of winter steelhead distribution in the Willamette Basin, and a spawning tributary for spring chinook. These are both DPS/ESU listed species, and little is known about their distribution and life history in the Calapooia River. A Rapid Bioassessment was completed in 2015 as well as winter steelhead redd survey in 2017 to try and establish baseline data including spawning gravel abundance/seeding availability, adult escapement, a foundation for long term trend analysis, as well as identify anchor habitats. The survey was also intended to inform ODFW with vital information regarding the possibility of jump-start seeding the Calapooia with Chinook, as well as guide the Calapooia WC’s restoration approach in this vital area. The 2017 return of Winter steelhead over the Willamette Falls (pinch point for all anadromy in the Willamette Valley) was the lowest on record, and the CWC and partners do not feel a proper baseline was established. The CWC proposes to complete 2 years of STW redd Surveys to create a baseline of adult escapement from 2 different cohorts, as well as collect summer water temperature data through the deployment of Hobo temperature loggers. This data can be used to create a reach wide restoration plan that will focus CWC restoration efforts in areas where they will be the most efficient and effective.

  Citation × Citation Citation Abstract Copy Title: Oregon's Coastal Chinook, A Summary Abstract -- Whether they are landed by anglers using rods and reels, or commercial fishermen using troll gear, chinook salmon are prize fish. These fish have been an important cultural and economic element of Oregon's coastal economy for more than 100 years. Although human activity has affected the species during the past century, chinook remain today a strong and extremely valuable component within the state economic system. In 1987, for example, commercial and recreational fisheries caught more than a half-million chinook. Most of those fish had their origin in coastal streams of Oregon and northern California. This report summarizes the findings of a study that offers a comprehensive view of Oregon's coastal chinook salmon populations based on the best information currently available. The study is titled "Chinook Salmon Populations in Oregon Coastal River Basins: Description of Life Histories and Assessment of Recent Trends in Run Strengths." The study does not deal with chinook stocks of the Columbia River Basin. A limited supply of document copies is available for public review at libraries and department offices around the state.

The sustainability of the North Umpqua steelhead population and its' habitat is a very high priority. The Oregon Department of Fish and Wildlife (ODFW) develops, on a continuing basis, practices designed to ensure the health and viability of this population. However, continued management success depends critically on the availability of data necessary for a detailed understanding of relevant life history issues. To address these data needs, ODFW began a radio-telemetry study of North Umpqua steelhead in June of 1998. Tagging at Winchester dam was terminated 10/26/00 but monitoring continued until the end of May 2001. This study has provided detailed information on movement patterns of adult steelhead in the basin at a level that is available in no other way and is the most comprehensive project of its type for the Umpqua Basin. A radio tagging study whose scope was limited to the Steamboat Creek subbasin was carried out previously (Wroble, 1990). Also, a previous study of temperature trends in that subbasin is of interest (Hostetler, 1991). Although similar radio telemetry studies ( e.g. Hockersmith et al, 1995) have been carried out in other basins, they are few.

This study is part of a larger effort to develop similar high-quality escapement estimates for fall chinook in Oregon coastal basins in order to meet Oregon’s Pacific Salmon Treaty monitoring responsibilities. Funding for this study was provided by the U.S. Section of the Chinook Technical Committee (CTC) of the Pacific Salmon Commission (PSC) pursuant to the 1999 Letter of Agreement (LOA). Three stock aggregates have been identified that originate from Oregon coastal basins. These aggregates are thought to represent distinct genetic and behavioral characteristics and are managed separately. The North Oregon Coast (NOC) and Mid Oregon Coast (MOC) are the two stock aggregates that are north migrating, and are subjected to the PSC’s abundance-based management program (USCTC 1997). The South Fork Coos River is one component of the MOC aggregate. Current monitoring programs for Oregon coastal fall chinook do not supply the CTC with adequate information that is required for the management and rebuilding of Oregon’s coastal chinook stocks. ODFW has conducted standard surveys for more than 50 years to monitor the status of chinook stocks along coastal Oregon (Jacobs et al. 2000). A total of 56 standard index spawner surveys (45.8 miles) are monitored throughout 1,500 stream miles on an annual basis to estimate peak escapement levels and track trends of northmigrating stocks. Although counts in these standard surveys may be sufficient to index long-term trends of spawner abundance, they are considered inadequate for deriving reliable annual estimates of spawner escapement for several reasons. These surveys were not selected randomly and cannot be considered representative of coast-wide spawning habitat. Also, fall chinook are known to spawn extensively in mainstem reaches and large tributaries, which are not conducive to the foot surveys. To provide estimates of escapements, index counts must be calibrated to known population levels. Obtaining accurate estimates of fall chinook spawner density in mainstem reaches is extremely difficult. Typically, these areas exhibit wide variations in stream flow and turbidity that create difficult and sometimes dangerous survey conditions resulting in unreliable visual counts. The goal of this project is to develop precise estimates of adult spawner escapement in the South Fork Coos River and to identify survey methods that can be used to reliably index spawner abundance for the South Fork Coos River and MOC stock aggregate. ODFW conducted mark-recapture experiments to estimate fall chinook spawning escapement in the South Fork Coos River from 1998 through 2000. We conducted foot and float surveys to obtain counts of live fish, carcasses, and redds. These indices are assessed against the mark-recapture estimates to determine whether any of them track fall chinook spawner abundance with sufficient precision to form the basis for long-term monitoring and the incorporation of resulting escapement estimates into PSC harvest modeling efforts. We used radio-telemetry as an independent method to estimate the distribution of fall chinook spawners between mainstem and tributary strata.

Although the Oregon Plan for Salmon and Watersheds was initiated in response to the petition to list Oregon coastal coho salmon (Oncorhynchus kisutch) as threatened under the Endangered Species Act (ESA), monitoring was subsequently expanded to include other salmonids. Through coordinated surveys we are able to evaluate freshwater habitat, fish distribution, and abundance of juvenile and adult coho salmon and steelhead trout. The habitat survey project has the broadest geographic scope of inference and ties to other program components as well – basin surveys, surveys at habitat restoration sites, adult and juvenile coho surveys, and life cycle watersheds (Flitcroft et al. 2002). The Oregon Plan facilitated cooperation and partnerships to study the contemporary life history dynamics of coho salmon in the Oregon coastal ESU (Evolutionary Significant Unit). A viability and status assessment of Oregon coastal Coho (Chilcote 2005) and the Conservation Plan for the Oregon Coast Coho Evolutionary Significant Unit (Nicholas 2006) evaluated the relationship of aquatic habitat to the productivity of coho salmon populations and recommended actions to promote recovery. The habitat portion of the viability assessment was based on a review of aquatic and riparian habitat collected by the Aquatic Inventories Project (ODFW) from 1990 to 2004 (Rodgers et al. 2005). The authors of the habitat assessment (Rodgers et al 2005) and viability assessment (Chilcote 2005) concluded that coho productivity in 22 coastal coho populations was limited by the complexity of stream habitat used by juvenile coho during their first winter of freshwater residence. The term “stream complexity” integrates geomorphic and structural characteristics of streams and associated aquatic habitat. Complex geomorphic features may be observed in low gradient streams flowing through wide valley floors with multiple channels and off-channel habitats. Structural complexity refers to the size and configuration of pools, large wood pieces and jams, substrate, and undercut banks. The combination of geomorphic and structural features provides cover and refugia during high winter flows for juvenile coho. Stream reaches that can or have the potential to create these conditions are commonly located in lower reaches of moderate size streams in areas with wide valley floors and are considered to contain high quality habitat for juvenile coho. Burnett et al. (2007) developed spatial models to estimate high-quality habitat rearing potential, termed intrinsic potential, in coastal streams. A stream’s intrinsic potential was modeled using valley width, gradient, and stream flow. Historically, streams identified as having high intrinsic potential may have been the most productive for juvenile coho salmon; restoration of these reaches may be the key to recovery of coho salmon. The viability assessment and Coho Plan recommend that we monitor the trends in total amount and spatial distribution of these habitats in coastal drainages. This report discusses the findings from aquatic habitat surveys conducted in summer 2005 in coastal drainages. Our objectives are to describe and compare channel morphology, instream habitat and complexity, and riparian conditions in all wadeable streams in five monitoring areas. The sample design permitted us to post stratify the sample sites into three additional frames: sites within coho and steelhead distribution, sites outside coho distribution, and sites within high intrinsic potential for coho. We also used two habitat models to integrate habitat attributes to describe the habitat quality and capacity for different life stages of juvenile coho and steelhead.

Distribution metrics are specific to species and include site occupancy (the percent of sites with fish present) and pool frequency (average percent of pools per site with fish) for each Monitoring Area (MA), Evolutionarily Significant Unit (ESU) or Distinct Population Segment (DPS) in the project area. Abundance metrics are also specific to species and include the average density and population estimates in pools for each MA and ESU/DPS. Prior reports can be found at https://nrimp.dfw.state.or.us/crl/default.aspx?pn=WORP. Oregon Coast Coho (OCC) ESU density estimates were lower than in 2011. Pool population estimates and site occupancies were similar to 2011. We observed a small, but positive trend in occupancy and pool population estimates for coho across the ESU from 1998-2012. Within the four coastal monitoring areas, density and occupancy estimates were higher than the average from 1998-2011 in the Mid Coast MA, similar to the average in the Umpqua and North Coast, and lower in the Mid South. Pooling of data into three year “brood groups” indicated the current group had higher combined population estimates than the earliest two groups but was similar to 2004-2006 and 2007-2009. Site occupancy was higher in the current brood group than in any other group. Southern Oregon Northern California Coho (SONCC) ESU density and site occupancy estimates were the lowest recorded. Pool population estimates were similar to the average from 1998-2011. The current brood group had a higher population estimate than for 1998-2000, but the estimate was lower than all other brood groups. Site occupancy for current brood group was also lower than the other brood groups. Lower Columbia River Coho (LCR) density and pool population estimates were similar to 2011 and to the average from 2006-2011. Site occupancy was slightly below the average recorded from 2006-2011. Steelhead density, pool population, and pool occupancy estimates were similar to previous years in the Oregon Coast DPS. Site occupancies for the Oregon Coast DPS were the higher than average and similar to 2011. In the Klamath Mountain Province (KMP) DPS, steelhead density and pool frequency estimates were the lowest recorded. Population estimates were similar to the average and to 2011. Site occupancy was similar to the average condition and to 2011, however the estimates for the past 3 years have been the 2nd, 3rd, and 4th lowest estimates, respectively. Steelhead density estimates in the LCR and the Southwest Washington (SWW) DPSs were similar to each other and to the average and 2011 estimates for the DPSs. Site occupancy in the LCR was similar to 2011 and to the overall average. Site occupancy in SWW was higher than in 2011 and the overall average. Population estimates for both DPSs were similar to 2011 and to the overall average. Analyses which included shallower pools produced higher site occupancies in the Umpqua, Mid Coast and LCR for coho and in the Umpqua and the KMP for steelhead. Pool population estimates also increased with the addition of the smaller pools and had proportionately smaller confidence intervals.

The 2014 density estimate was also lower than the 1998-2013 average for the ESU. Site occupancy in 2014 was similar to 2013. Occupancy rates appear to be increasing for the ESU since the start of monitoring in 1998. The pool population estimate in 2014 was lower than in 2013 and lower than the average of the cohorts from 2010-2012. In the OCC ESU plots of parr abundance with female spawner abundance suggest limits in freshwater habitat to parr production when spawner abundance exceeds approximately 80,000 females. Parr production rates typically decrease when female spawner abundance increases. The Southern Oregon Northern California Coho (SONCC) ESU density estimate in 2014 was similar to the 2013 estimate. The 2014 density estimate was lower than the average for the ESU from 1998-2013. Site occupancy in 2014 was similar to 2013.

Results from 2015 are compared to previous years and used to describe trends in distribution and abundance. To access prior reports visit https://nrimp.dfw.state.or.us/crl/default.aspx?pn=WORP. Coho: Density estimates in 2015 for the Oregon Coast Coho (OCC) ESU were higher than in 2014, but similar to the 1998-2014 average for the ESU. Abundance estimates in 2015 were similar to 2004-2014, but higher than those in1998-2003. Site occupancy rates appeared to be increasing for the ESU since the start of our monitoring in 1998, although the rate from 2015 was lower than in 2014. The average occupancy rate from 2010-2015 has been similar to the average from 2004-2009 and higher than the average from 1998-2003. In the ESU plots of parr abundance against female spawner abundance suggest limits in freshwater habitat to parr production when spawner abundance exceeds approximately 80,000 females. Parr production rates in the ESU typically decrease when female spawner abundance increases. The density, number of sites at full seeding, occupancy, and pool frequency estimates in 2015 for the Southern Oregon Northern California Coho (SONCC) ESU were the lowest recorded since our monitoring began. Abundance estimates of parr from 2013-2015 were lower than those from 2001-2012 and similar to those from 1998-2000. Occupancy estimates for the last 4 cohorts have been the lowest recorded since monitoring began. Density estimates in 2015 for the Lower Columbia River Coho (LCR) were higher than in 2014 but similar to the average from 2006-2014 for the ESU. Abundance estimates of parr in 2015 were similar to the estimate in 2014 and to the 2006-2014 average. Site occupancy rates in 2015 were similar to the 2014 rate and the average rate from 2006-2014. Steelhead: The density, abundance, and occupancy rate estimates in 2015 for Oregon Coast Steelhead DPS were lower than in 2014 and lower than the 2002-2014 average for the DPS. The four cohorts previous to 2015 have had the four highest occupancy rates. Density in 2015 for the Klamath Mountain Province was lower than in 2014 and lower than the 2002-2014 average for the DPS. The 2015 and 2014 abundance estimates were the 1st and 2nd lowest recorded in the DPS. Site occupancy in 2015 was similar to 2014 and to the 2002-2014 average for the DPS. As in past years, the 2015 metrics for the two steelhead DPSs in the Lower Columbia River had similar metrics. Densities, pool frequencies, and point estimates for site occupancy and abundance were the lowest recorded in 2015. The original pool depth criteria was =40cm in maximum depth. This was changed to =20cm in 2010. Analyses based on the =20cm maximum depth criteria typically produce larger abundance estimates with proportionately smaller confidence intervals than analyses based on the =40cm maximum depth criteria. Abundance estimate trends that included shallow pools tracked with those based on the former pool criteria. Title: Juvenile Salmonid Monitoring In Coastal Oregon and Lower Columbia Streams, 2015 Report Number: OPSW-ODFW-2016-1 Abstract -- This report analyzes data from juvenile salmonid surveys in the three coho Evolutionarily Significant Units (ESU) and the four steelhead Distinct Population Segments (DPS) in coastal Oregon for 2015. Results from 2015 are compared to previous years and used to describe trends in distribution and abundance. To access prior reports visit https://nrimp.dfw.state.or.us/crl/default.aspx?pn=WORP. Coho: Density estimates in 2015 for the Oregon Coast Coho (OCC) ESU were higher than in 2014, but similar to the 1998-2014 average for the ESU. Abundance estimates in 2015 were similar to 2004-2014, but higher than those in1998-2003. Site occupancy rates appeared to be increasing for the ESU since the start of our monitoring in 1998, although the rate from 2015 was lower than in 2014. The average occupancy rate from 2010-2015 has been similar to the average from 2004-2009 and higher than the average from 1998-2003. In the ESU plots of parr abundance against female spawner abundance suggest limits in freshwater habitat to parr production when spawner abundance exceeds approximately 80,000 females. Parr production rates in the ESU typically decrease when female spawner abundance increases. The density, number of sites at full seeding, occupancy, and pool frequency estimates in 2015 for the Southern Oregon Northern California Coho (SONCC) ESU were the lowest recorded since our monitoring began. Abundance estimates of parr from 2013-2015 were lower than those from 2001-2012 and similar to those from 1998-2000. Occupancy estimates for the last 4 cohorts have been the lowest recorded since monitoring began. Density estimates in 2015 for the Lower Columbia River Coho (LCR) were higher than in 2014 but similar to the average from 2006-2014 for the ESU. Abundance estimates of parr in 2015 were similar to the estimate in 2014 and to the 2006-2014 average. Site occupancy rates in 2015 were similar to the 2014 rate and the average rate from 2006-2014. Steelhead: The density, abundance, and occupancy rate estimates in 2015 for Oregon Coast Steelhead DPS were lower than in 2014 and lower than the 2002-2014 average for the DPS. The four cohorts previous to 2015 have had the four highest occupancy rates. Density in 2015 for the Klamath Mountain Province was lower than in 2014 and lower than the 2002-2014 average for the DPS. The 2015 and 2014 abundance estimates were the 1st and 2nd lowest recorded in the DPS. Site occupancy in 2015 was similar to 2014 and to the 2002-2014 average for the DPS. As in past years, the 2015 metrics for the two steelhead DPSs in the Lower Columbia River had similar metrics. Densities, pool frequencies, and point estimates for site occupancy and abundance were the lowest recorded in 2015. The original pool depth criteria was =40cm in maximum depth.

Monitoring data are used to evaluate trends in salmonid distribution and abundance, which inform conservation and recovery decisions. The analysis in this report spans the years 1998-2016. Previous annual reports can be found at: https://nrimp.dfw.state.or.us/crl/default.aspx?pn=WORP. Juvenile Coho Salmon: For both the Oregon Coast Coho (OCC) and Lower Columbia River (LCR) ESUs, abundance estimates were lower in 2016 relative to the average from the 2013-2015 broods. The 2016 LCR abundance estimate was the lowest recorded in the 11 years of monitoring in this ESU. In the Southern Oregon Northern California Coho (SONCC) ESU the 2016 abundance estimate was similar to the average of the estimates for the 2013- 2015 broods. The 2016 estimate of site occupancy, relative to the estimate for the 2013- 2015 broods, was lower in the LCR, and similar in the OCC and the SONCC. As with the abundance estimate for the LCR, the 2016 estimate of site occupancy was the lowest recorded since monitoring began in the ESU. In the OCC there is some indication from Coho Salmon survey data that freshwater productivity rates are regulated by compensatory density dependence at one or several early life stages. In the OCC metapopulation, the spawner:summer parr (recruit) curve is sigmoidal in years of higher female spawner abundance, suggesting some factor (or combination of factors) that sets juvenile carrying capacity. A density dependent pattern has not been observed in the LCR, likely due to relatively low seeding levels in the ESU. For the SONCC there are insufficient adult data to perform these analyses. Juvenile Steelhead: For the Oregon Coast (OC) and the Klamath Mountains Provence (KMP) DPSs, the average of the abundance estimates for the 2014-2016 broods was similar to the average for the 2010-2013 broods. The 2016 abundance estimate was similar to the average of the 2006-2015 estimates in the South West Washington (SWW) DPS and lower than the average of the 2006-2015 estimates in the Lower Columbia River (LCR) DPS. Site occupancy estimates in the OC and KMP in the 2014-2016 broods were similar to the estimates for the 2010-2013 broods. Site occupancy estimates in 2016, relative to the average of the 2006-2015 estimates, were similar in the SWW and lower in the LCR. From 1998 to 2009 pools were required to be =40cm in maximum depth to meet survey protocols. This was changed to =20cm in maximum depth in 2010. Analyses based on the =20cm maximum depth criteria, relative to the =40cm maximum depth criteria, typically produce increases in site occupancy rates and larger abundance estimates with proportionately smaller confidence intervals.

  Citation × Citation Citation Abstract Copy Title: 2009 Foskett Spring Speckled Dace Investigations Progress Report 2009 Abstract -- Speckled dace (Rhinichthys osculus) are geographically widespread throughout the western United States and occur in many isolated subbasins and interior drainages in south-central Oregon. The Foskett Spring speckled dace (R. osculus ssp.) is represented by a single population that inhabits Foskett Spring (Figure 1) on the west side of Coleman Lake (Warner Lakes subbasin) in Lake County, Oregon. Foskett speckled dace was listed as threatened under the federal Endangered Species Act in 1985 (U.S. Fish and Wildlife Service 1985). The Foskett speckled dace became isolated in Foskett Spring at the end of the Pluvial period (~9,000-10,000 years ago). Foskett Spring is a natural spring that rises from a springhead pool, flows through a narrow spring brook into a series of shallow marshes, and then disappears into the soil of the normally dry Coleman Lake (Figure 1). A second population in Dace Spring, located approximately 0.8 kilometer south of Foskett Spring, was established from an introduction of 100 fish from Foskett Spring in 1979-1980 (Williams et al. 1990); however recent surveys have failed to document their continued existence at this location. In 1987, the U.S. Bureau of Land Management (BLM) acquired, through exchange, the 65 hectare parcel of land containing Foskett and Dace Springs. Both sites were fenced to exclude livestock. The Recovery Plan for the threatened and rare native fishes of the Warner Basin and Alkali Subbasin states that Foskett speckled dace will probably not be delisted in the near future because of its extremely isolated range and potential for degradation of its habitat from localized events (USFWS 1997). The primary recovery objective for this species is long-term persistence through preservation of its native ecosystem. The plan further states that the conservation and long term sustainability of this species will be met when: 1) long-term protection of its habitat, including spring source aquifers, springpools and outflow channels, and surrounding lands is assured; 2) long-term habitat management guidelines are developed and implemented to ensure the continued persistence of important habitat features and guidelines include monitoring of current habitat and investigation for and evaluation of new spring habitats; and 3) research into life-history, genetics, population trends, habitat use and preference, and other important parameters is conducted to assist in further developing or refining criteria 1) and 2), above. Actions needed to meet these criteria include protecting the fish population and its habitat, conserving genetic diversity of the fish population, ensuring adequate water supplies are available, monitoring of the dace population and habitat conditions, and evaluating long-term effects of climatic trends on recovery of this fish population. The purpose of this investigation was to determine the status of the federally listed Foskett Spring speckled dace and its habitat. This report updates a monitoring program initiated in 2005 by ODFW (Scheerer and Jacobs 2005) by providing results of monitoring conducted in 2009. Specifically, this monitoring program calls for biannual estimates of population abundance, assessments of distribution and demographic parameters and assessments of physical habitat conditions.

  Citation × Citation Citation Abstract Copy Title: A Proposal for an Integrated Research Monitoring Program for Oregon Coastal Chinook Populations Abstract -- Among the many chinook salmon populations contributing to large, mixed stock ocean net, troll, and recreational fisheries managed by the Pacific Salmon Commission (PSC) there is a good deal of diversity with respect to productivity, life history characteristics, and ocean distribution. During the years immediately following the adoption of the original 1985 Pacific Salmon Treaty (PST), lack of adequate data prevented the PSC from managing effectively for these differences. Instead, chinook management outlined in Annex IV of the original treaty was based upon long term population trends for very large aggregates of stocks. Although harvest ceilings were established as part of a PST recovery plan for over-exploited stocks, they were based on average coast-wide production trends and resulted in over harvest of weak stocks in some years and failure to take advantage of large returns in other years. By the mid-l 990's, data relative to the distribution and abundance of many salmon stocks contributing to PST fisheries was improving. At the same time, there was increasing dissatisfaction with quota-based management and strong interest in instituting annual abundance-based management for stock aggregates that share geographic proximity of spawning areas, similar life history and genetic characteristics, and similar distributions in the ocean. Abundance-based management for aggregated stocks would establish and implement annual fishery exploitation rates in fisheries that insure long-term sustainability for all aggregates and related individual stocks. In the absence of bilateral agreement between the U.S. and Canada regarding implementation of abundance-based management, the three voting U.S. PSC Commissioners signed the 1996 Letter of Agreement (LOA) that defined elements of an abundance-based management approach for chinook salmon fisheries in southeast Alaska. The LOA was designed to: 1) set the stage for future bilateral negotiations regarding abundance based management; 2) clarify the role of PST fisheries in rebuilding depressed natural stocks; and 3) provide a means for sharing conservation responsibility of far-north migrating stocks originating from watersheds in Oregon and Washington. The foundation for abundance-based management set forth in the LOA was subsequently expanded upon and incorporated as Aggregate Abundance-Based Management (AABM) in Annex IV, Chapter 3 of the 1999 PST. Application of the abundance-based management outlined in the 1996 LOA and the subsequent 1999 amendments to the PST requires knowledge of the stock recruitment relationships, biological spawning escapement goals, and annual forecasts of ocean abundance and distribution for stocks in each aggregate to regulate fishery harvest. Managers must also have annual post-season estimates of aggregate specific exploitation rates and in-river escapements to assess the effectiveness of regulatory measures. The base-monitoring program for Oregon's coastal chinook under the 1985 PSC met only a few of these data requirements. In recognition of requirements for new and more precise data, the signatories of the original LOA sought out additional federal funds for new and expanded monitoring programs. Since 1997 Congress has annually approved approximately $1.8 million for additional research and monitoring needed to implement terms of the LOA. The PSC delegated discretionary authority for the use of those funds to the U.S. Section's Chinook Technical Committee (CTC).

  Citation × Citation Citation Abstract Copy Title: OWEB Grant Number 208-2084 Project Completion Report - PUR Monitoring Abstract -- While it is assumed that habitat enhancement and fish passage improvements increase fish production, there is little empirical data to support that claim in the Umpqua Basin. The Umpqua District has used smolt traps in the past to both establish a baseline record and to attempt to determine any response to habitat enhancement (Brush, Hinkle, and Big Tom Folley Creeks). Brush Creek and Big Tom Folley were originally chosen as monitoring sites since they are similar in characteristics, and Brush was originally the treatment stream for restoration projects while Big Tom Folley was used as the control until later projects occurred. Currently, there are PUR habitat enhancement projects scheduled to take place within the Little Wolf Creek and Wolf Creek basins. In order to gain more insight as to whether restoration efforts improve fish populations and address limiting factors, baseline and post treatment surveys will be needed. Restoration that is planned in Wolf and Little Wolf Creeks in 2008 and 2009 provides a unique opportunity to examine stream and fish responses to log-only and boulder-only instream placements. Pre-treatment data exists on these streams for smolt outmigration, summer habitat, spawning adults, summer seeding, channel cross-sections and temperature. ODFW has been collecting smolt out-migration data at five sites in the Upper Umpqua and Elk Creek watersheds almost continuously for 15 years to monitor yearly trends and to calculate over-winter survival rates of coho and steelhead. This OWEB grant will add to this baseline data and provide funding to continue past monitoring and add new monitoring components. Continuous smolt trap data from Brush, Big Tom Folley, and Hinkle Creeks is important to future efforts to monitor watershed health. Extensive habitat enhancement and fish inventories have been completed within the Hinkle Creek, Brush Creek and Big Tom Folley Creek basins. The Oregon Department of Fish and Wildlife (ODFW) Umpqua Watershed District joined with the Partnership for the Umpqua Rivers (PUR) in an effort to continue ongoing juvenile monitoring within the Umpqua Basin. Since little is known about stream-specific limiting factors and fish production response to various habitat restoration treatments such as log or boulder placement, these long term data sets will help to understand the fish response aspect related to or resulting from habitat restoration projects.

  Citation × Citation Citation Abstract Copy Title: Luckiamute Rapid Bio-Assessment Abstract -- The 2011 Rapid Bio-Assessment inventory of the Luckiamute Watershed was a replicate inventory that attempted to target the most productive salmonid habitats in the basin. This was the fourth consecutive inventory in the basin designed to describe the distribution and relative abundance of coho, cutthroat trout and winter steelhead. The entire basin (214 stream miles) was inventoried in 2008 utilizing the RBA protocol which included many miles of dysfunctional aquatic habitats that currently exhibit deep channel entrenchment, elevated summer temperature profiles and provided limited summer production potential. Survey efforts were reduced to 96.6 stream miles in 2009 and covered only the highest quality habitat reaches. Surveys were further refined in 2010 to a subset of the highest quality habitats (90.2 stream miles) and reduced again in 2011 to 84.6 stream miles. Some streams in the basin were also surveyed in 2002 and 2003 in a separate effort funded by Boise Cascade, the previous owner of the current Forest Capital holdings. These included Beaver, Boulder, Clayton, Cougar, Miller, Pedee, Ritner, Sheythe, West Fork Luckiamute, Wolf, and approximately 7 miles of the upper Luckiamute mainstem. Results and comparisons to those surveys are included below in the Site Specific observations. The intent of the RBA inventory was to gather information on the status of juvenile salmonid summer distributions and summer rearing densities. The inventory consisted of extensive snorkel surveys that began at the mouth of each stream and continued to the end of significant salmonid rearing potential (not to the end of cutthroat distribution). These surveys will be used to develop a base line for understanding how juvenile salmonids are currently utilizing habitats within the basin during summer flow regimes. Replicates of this inventory in high priority stream reaches (streams exhibiting residual system function) will be critical for identifying trends in the distribution and abundance of juvenile coho, steelhead and cutthroat in response to watershed restoration and management. The Rapid Bio-Assessment (RBA) survey method was designed to sub-sample 20 percent of the pool habitats using a Rapid Assay technique that could cover large distances and succeed in describing the current distribution of juvenile salmonids in all of the surveyed streams and their tributaries. Beaver dam frequency was also recorded.

Funding support of the project is shared by the Bonneville Power Administration, the State of Oregon, Mitchell Act, fisher/processor voluntary contributions, and occasionally, ODFW’s Restoration and Enhancement program. The longevity of the partnership between the various entities involved in the SAFE project is a testament to the effectiveness of cost sharing and cooperation of multiple government agencies. In 2007 the SAFE project was retitled Select Area Fisheries Enhancement to reflect the progression from project implementation and research toward a goal of maximizing fisheries potential. This report summarizes activities and findings of the SAFE project during fall 2006 through summer 2008, but includes some earlier information for context and to identify trends. Key findings and results are: (1) Since 1993, Select Area commercial fisheries have contributed an average of 55% of spring Chinook, 45% of coho, and 20% of fall Chinook to the total non-Treaty Columbia River commercial harvest. (2) Average harvest rates of 91% for spring Chinook, 99% for coho, and 97% for SAB fall Chinook produced by the SAFE project far exceed rates for production from other regional hatcheries which typically have high escapement rates due to complexities associated with harvest in mixed-stock fisheries of the mainstem Columbia River. (3) On average, 19% of spring Chinook, 58% of SAB fall Chinook, and 32% of coho production from the SAFE project is harvested in other regional recreational and commercial fisheries. (4) Due to spatial separation, Select Area fisheries have far less impact on non-target stocks per harvested fish than do mixed-stock commercial and recreational fisheries occurring in the mainstem Columbia River, even when these fisheries utilize markselective harvest methods. (5) Stock composition in Select Area winter, spring, and summer commercial fisheries averages 91% local stock. Fall fisheries average 87% local Chinook stocks and 80% local coho stocks.

A total of 2,876 PIT tagged juvenile salmon and steelhead and 104 adults were detected. Mean fork length at emigration for natural summer steelhead was 168 mm. Age at emigration was 29.9% age-1 and 70.1% age-2. Condition factor for steelhead smolts was poor (< 1.00) throughout the season and Neascus sp. (black spot), continued to be prevalent. Median emigration time to TMFD and John Day Dam (JDD) for natural summer steelhead occurred in the middle of May (5/14-5/20) compared to late May (5/21-5/27) at Bonneville Dam (BON) and early June (5/28-6/3) at the Columbia River Estuary. Abundance for natural origin summer steelhead was 33,883 ± 4,262 smolts. Survival from Meacham Creek to TMFD, TMFD to JDD, and JDD to BON for the 2009 outmigration year was 47%, 60%, and 38%; respectively. For brood year 2007, we estimated the production of 16 smolts-per-female for summer steelhead. Egg-to-smolt survival for summer steelhead in brood year 2007 was 0.3% and smolt-to-adult return for outmigration year 2007 was 5.4%. The number of spawning females and egg deposition appeared to be associated with the growth, age composition, and production of summer steelhead smolts, thus providing evidence for density dependent effects. Growth appeared to be better during the first rearing season when fish densities were low, leading to a higher composition of age-1 smolts and more smolts produced per spawning female. The downward trend observed in egg-to-smolt survival and correlation between summer low flows and egg-to-smolt survival suggest that smolt production and freshwater productivity of summer steelhead is limited by the quantity and quality of available freshwater habitat.

  Citation × Citation Citation Abstract Copy Title: Steelhead Escapement Monitoring In the Upper Grande Ronde River - Annual Technical Report 2008 Abstract -- The Upper Grande Ronde River basin supports a population of summer steelhead O. mykiss that has been defined by segregating it from the other three populations inhabiting the 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. Steelhead in the Grande Ronde River basin compose part of the Snake River DPS for summer steelhead and are listed as threatened by the ESA. Despite recovery efforts, these populations remain depressed relative to historic levels. This project will evaluate summer steelhead population abundance for the upper Grande Ronde River summer steelhead population by conducting surveys of redds and spawning activity. These surveys will 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. We monitored steelhead using a probabilistic sampling approach by incorporating a sample-site selection procedure similar to the Environmental Protection Agency (EPA) environmental monitoring and assessment program (EMAP). We used this EMAP or Generalized Random Tessellation Stratified design (GRTS) approach to select sample sites for status and trend monitoring of steelhead redds within the Upper Grande Ronde River watershed. This steelhead monitoring follows the Oregon Plan for Salmon and Watersheds Monitoring Program approach. ODFW, Eastern Oregon Fish Research (EOFR). Funded by NOAA.

Across all sampling years, sites were randomly selected using Generalized Random Tessellation Stratified (GRTS) design, which provides a random spatially balanced sample allowing for statistically rigorous evaluation of status, trend and distribution at multiple spatial scales. A total of 700 site surveys were conducted over the course of the study covering nearly 2% of the entire 2,420 km sampling frame. Abundance of age-1+ redband trout at the SMU level has remained relatively stable throughout the course of this study but has decreased since intensively sampled in 1999. Estimates of landscape-wide abundance of age-1+ redband trout were of similar magnitude and had comparable precision across all three study years, averaging 878,000 + 16%. However, abundance at the SMU and population (stratum) level showed substantial variation, both spatially and inter-annually. Fish densities (fish/m) sampled at sites visited annually (2007-2009) showed significant differences between years, specifically between 2007 and 2009 in the Chewaucan and Fort Rock SMUs. Target levels of relative precision were achieved twice at the SMU level, and in approximately half of the strata. Increasing the number of sites sampled to increase precision is not likely, given limited funding. Yet, the current study design falls short of providing precise information to develop conservation management plans. Alternative sampling designs that would maximize data acquisition at the population level, while allowing for estimates of yearly variation were explored and suggested.

To explore these relationships we linked multi-year data sets of overwinter survival rates from three streams within the Oregon Coast Coho Evolutionarily Significant Unit (OCC) to summer parr abundance estimates from calibrated OCC-wide snorkel survey counts to estimate annual Coho Salmon smolt abundance from 2000-2017. Smolt abundance estimates ranged from a low of 0.9 million in 2000 to a high of 4.1 million in 2013 within the OCC. Accuracy of the smolt abundance estimates was tested using two datasets: (i) adult abundance modeled from the corresponding smolt abundance estimate was compared with adult abundance derived empirically from spawning ground surveys and (ii) our smolt abundance estimates were compared with smolt abundance estimates from trapping efforts in select basins within the OCC. Adult abundance modeled from smolt abundance estimates was highly correlated with adult abundance from spawning ground surveys (r = 0.88, p < 0.001) and smolt abundance estimates correlated with abundance from smolt trapping efforts (r = 0.81, p <0.001). Graphical relationships between smolt abundance and parental abundance suggest that freshwater productivity may be limited in the OCC by density dependent processes at spawner levels observed since 1998. Additionally, smolt abundance estimates have potential use as a variable in adult forecast models and could be used to assess trends in freshwater productivity and to probe factors of density dependence.

SAFE reports are intended to summarize the best available scientific information concerning the past, present, and possible future condition of the stocks, marine ecosystems, and fisheries being managed under federal regulation. Regional Fishery Management Councils use this information to determine annual harvest levels for each stock; document significant trends or changes in the resources, marine ecosystems, and fishery over time; and assess the relative success of existing state and federal fishery management programs. This is the eight Status of the Pacific Coast Coastal Pelagic Species Fishery SAFE document prepared for the Pacific Fishery Management Council (Council). Following NMFS guidelines, the purpose of this report is to briefly summarize aspects of the coastal pelagic species (CPS) FMP and to describe the history of the fishery and its management. Species managed under this FMP include: Pacific sardine (Sardinops sagax), Pacific mackerel (Scomber japonicus), northern anchovy (Engraulis mordax), jack mackerel (Trachurus symmetricus), and market squid (Loligo opalescens). The SAFE report for Pacific Coast CPS fisheries was developed by the Council’s Coastal Pelagic Species Management Team (CPSMT) from information contributed by scientists at NMFS, Southwest Fisheries Science Center (SWFSC), California Department of Fish and Game (CDFG), Oregon Department of Fish and Wildlife (ODFW), and Washington Department of Fish and Wildlife (WDFW). Included in this report are descriptions of landings, fishing patterns, estimates of the status of stocks (including stock assessments for Pacific sardine and Pacific mackerel, Appendix 1 and Appendix 2), and acceptable biological catches (ABCs). The ABC recommendations, together with social and economic factors, are considered by the Council in determining annual harvest guidelines and other measures for actively managed fisheries (i.e., Pacific mackerel and Pacific sardine).

Degraded and fragmented habitat and negative interactions with nonnative fishes have led to a decline in bull trout distribution and abundance, several local extirpations, and a federal listing in 1998 as a threatened species under the Endangered Species Act (USFWS 2002). Distribution and abundance of bull trout also have declined in Oregon, and most management units in the state are considered to be threatened by conservation risks (ODFW 2005). One of these at-risk management units exists in the Hood River basin (ODFW 2005). Bull trout in Hood River basin currently are thought to exist as two independent reproductive units (USFWS 2002), known as local populations (Rieman and McIntyre 1995). The Clear Branch local population was isolated from the rest of the basin by the construction of Clear Branch Dam in 1968. This dam provides limited downstream fish passage during periods of spill and no voluntary upstream passage. Bull trout in this population inhabit Laurance Lake reservoir and the tributaries Pinnacle Creek and upper Clear Branch, which flow into the reservoir. The Hood River local population is distributed in the mainstem Hood River, Middle Fork Hood River (Middle Fork), and a few Middle Fork tributaries. Fluvial migrants from Hood River basin also forage and winter in the Columbia River (Pribyl et al. 1996, Buchanan et al. 1997). Bull trout have been observed in the East and West Fork basins of the Hood River, but these sightings have been rare. Presently, there is little evidence to suggest local populations exist in these tributary basins (USFWS 2002, Reagan and Olsen 2008). The status of both local populations is extremely precarious. Threats that put the Clear Branch population at risk of extirpation include low abundance, negative interactions with illegally introduced smallmouth bass, isolation from upstream migration and immigration, and diminished spawning and rearing habitat (USFW 1998). The Hood River population also appears to be small and is affected by passage barriers, unscreened irrigation diversions, impaired water quality, and periodic debris flows during glacial outbursts (USFWS 1998). As mandated by their federally designated threatened status, recovery plans were drafted by the US Fish and Wildlife Service (USFWS) for each distinct population segment, including for Hood River bull trout in 2002. This draft plan listed four goals for recovery in this basin: 1) establish at least one more local population in addition to the two existing populations, 2) increase the estimated adult population in the basin to at least 500 individuals, 3) achieve a stable or increasing trend at the population recovery level for at least two generations (=10 years), and 4) improve habitat connectivity by addressing problems with passage and screening at diversions and seasonal water quality barriers (USFWS 2002). The recovery plan also sets out research and monitoring needs critical to the recovery of these populations. Needed are accurate adult abundance estimates; a standardized monitoring program; more life history information for each local population, including how Hood River bull trout use of the Columbia River and the effects of potential passage obstructions on movement; and more information on the threat posed to the Clear Branch population by the illegal introduction of smallmouth bass in Lake Laurance reservoir. The Oregon Department of Fish and Wildlife (ODFW), with the help of the USDA Forest Service (USFS), initiated a four-year study in 2006 seeking to address these needs by synthesizing available data and conducting further studies to improve our understanding of the abundance, life history, and potential limiting factors of bull trout in the Hood River recovery unit. This report describes our findings, summarizes previous studies in the context of new information, and recommends a standardized monitoring protocol and future research. Our specific study objectives were as follows: 1. Assess adult abundance of the Clear Branch local population and develop a monitoring protocol to track abundance trends that is statistically reliable, cost-effective, and that minimizes potential adverse effects on this small isolated population. 2. Describe the juvenile and adult life history patterns of the Clear Branch local population. 3. Assess the potential impact of smallmouth bass on bull trout in Laurance Lake reservoir. 4. Determine current distribution of bull trout reproduction and early rearing in potential bull trout streams in the Hood River basin. 5. Describe the migratory life history of Hood River bull trout and assess the potential impacts of Coe Diversion and two new falls on the Middle Fork Hood River (scoured by the November 2006 glacial outburst) on bull trout migrations.

  Citation × Citation Citation Abstract Copy Title: Tenmile Lake Basin Partnership - OWEB Final Report: Grant 217-2051 Abstract -- Pacific Lamprey are native to the Tenmile Watershed and culturally important to the local Native American Tribes. Likewise, Salmon and Steelhead have both an economic and cultural significance to the local citizens and Tribes. Pacific Lamprey were historically harvested by the people of the Confederated Tribes of the Coos, Lower Umpqua and Siuslaw Indians (CTCLUSI), but it was unknown if Pacific Lamprey were still present in the Tenmile Watershed. A fish trap was built on Eel Lake by the Oregon Department of Fish and Wildlife (ODFW) in 1989 for the purpose of fish capture and rearing. The trap is effective in capturing Salmon and Steelhead but may act as a barrier to the passage of Pacific Lamprey. This monitoring effort was designed to assess the presence/absence of Pacific Lamprey in the Tenmile Watershed, identify migration timing, potential lamprey passage barriers and rearing/spawning habitats, and collect and organize data from Eel Lake Trap on native Coho, Cutthroat, and native/hatchery Steelhead returns and trends. Lamprey larvae (ammocoete) monitoring was conducted in the summer of 2017 using electro-shockers. Shocking occurred on 3 tributaries of Tenmile Lakes (Big Creek, Johnson Creek, and Shutter Creek), and 3 creeks within the Eel Lake basin (Eel Creek, Clear Creek, and Winters Arm Creek). Two species of lamprey were identified, Western Brook (Lampetra richardsoni) and Pacific (Entosphenus tridentatus). Western Brook were found in all sampled Tenmile Lakes Basin streams, but only in the streams above Eel Lake Trap in the Eel Lake Basin. No Western Brook were identified in Eel Creek below the Trap. Pacific Lamprey were found in Johnson Creek and Big Creek in the Tenmile Lakes Basin, and in Eel Creek in the Eel Lake Basin. No Pacific Lamprey were identified above the Eel Lake Trap, suggesting that it may act as a complete passage barrier to that species. In addition, over 200 adult Pacific Lamprey were salvaged from an ODOT culvert enhancement project on Eel Creek near Hwy 101. Pacific Lamprey larvae were identified upstream of this project, but it is likely that it was a partial barrier. Two other ODOT culverts were identified as potential partial lamprey barriers on Eel Cr. Spawning areas for Pacific and Western Brook Lamprey are similar to spawning areas for salmon. Upper reaches of all the Tenmile Lake tributaries have appropriate spawning gravel. Lower stream areas are often high in sediment which is conducive to rearing lamprey larvae. This was confirmed in Johnson creek with high numbers of Pacific Lamprey larvae found at the mouth as it enters South Tenmile Lake. Farther upstream in the Johnson Creek system, larvae were abundant, but much smaller with many being too small to identify (<65mm). Western Brook larvae were found, but no Pacific Lamprey larvae were identified, perhaps amongst those unidentified specimens. Western Brook ammocoetes were also found at the lower site on Johnson Creek, and in Big Creek and Shutter Creek. Pacific Lamprey migration into the watershed is difficult to determine due to the elusive nature of the species and their life cycle trait of migrating in from the ocean in the spring of one year, then holding over until the next spring before spawning. When specimens are captured, it is difficult to determine whether it is a fresh migrant or last year’s holdover. Even if it can be determined which year it is from, it is still difficult to know how long it has been in the system before it was captured. In Phase 2 of this project, we will capture Pacific Lamprey either in traps near the mouth of Eel Cr, or at the lower culverts. This should give us a better sense of migration timing. Native Coho salmon counts at Eel Lake Trap were down significantly from the recorded high at the Trap of 441 in 2012, with only 66 native Coho returning in 2018 (the winter of 2017-2018). The previous 2 years were also low with 2016 and 2017 showing returns of only 53 and 118 respectively. The Coho numbers for most of the Oregon Coast also showed low returns. Hatchery Winter Steelhead counts were 502 for 2018. This compares to a record high of 828 in 2007, 595 in 2016, and 226 in 2017. Returning native Steelhead only numbered 10 for the 2018 season. The average return for Native Steelhead is 24. In 2018, 60 Steelhead were spawned including 2 native males, but no native females. 252 hatchery Steelhead were recycled into Saunders Lake, and 148 into Butterfield Lake. ODFW allocated 25,000 smolts for the Tenmile Watershed, which were acclimated and then released in April 2018.

  Citation × Citation Citation Abstract Copy Title: Oregon Chub Investigations, Progress Report 2001 Abstract -- Populations of Oregon chub Oregonichthys crameri, endemic to the Willamette Valley, have been drastically reduced. Factors in the decline of this fish include changes in flow regimes and habitat characteristics resulting from the construction of flood control dams, revetments, channelization, diking, and the drainage of wetlands. The Oregon chub is further threatened by predation and competition by non-native species such as largemouth bass Micropterus salmoides, small mouth bass M. dolomieui, crappies Pomoxis sp., sunfishes Lepomis sp., bullheads Ameiurus sp., and western mosquitofish Gambusia affinis. We surveyed in the Willamette River drainage in April-October 2000 to quantify existing Oregon chub populations, search for unknown populations, evaluate potential introduction sites, and monitor introduced populations. We sampled a total of 77 sites in 2000. We collected Oregon chub for the first time from Barnard Slough in the Middle Fork Willamette drainage. Oregon chub were last collected from this location in 1983 (Bond 1984). Thirty-one of the 77 sites were new sites that were sampled for the first time in 2000. Forty-six sites, sampled in 1991-1999, were revisited. Three sites were sampled twice. We confirmed the continued existence of Oregon chub at 20 locations. These include naturally occurring populations in the Santiam drainage (Geren Island, Santiam Conservation Easement, Gray Slough, Santiam 1-5 backwaters, Pioneer Park backwater, Santiam Public Works Pond), Mid-Willamette drainage (Finley Gray Creek Swamp) and Middle Fork Willamette drainage (Dexter Reservoir Alcoves, East Fork Minnow Creek Pond, Shady Dell Pond, Buckhead Creek, Oakridge Slough, Elijah Bristow State Park, Rattlesnake Creek, and Hospital Pond) and introduced populations in the Middle Fork Willamette (Wicopee Pond, Fall Creek Spillway Ponds), Santiam (Foster Pullout Pond), and Mid-Willamette drainages (Dunn Wetland, Finley Display Pond). Oregon chub were not found at several locations (Jasper Park Slough, Wallace Slough, East Ferrin Pond, Dexter East Alcove, Hospital lmpoundment Pond, Logan Slough, Green's Bridge Backwater, Camas Swale) where they were collected on at least one occasion between 1991-1999 (Scheerer et. al. 1992; 1993; 1994; 1995; 1996; 1998; 1999; 2000; Scheerer and Jones 1997). Non-native fish were common in off-channel habitats that were surveyed in the Willamette River drainage. Non-native fish were collected from 23 of the 31 new sites sampled in 1999 (74%); no fish were collected at three locations (10%). Western mosquitofish and centrarchids (largemouth bass and bluegill) were the most common non-native fish collected. Oregon chub were introduced into Menear's Bend Pond in the Santiam River drainage in the October 2000. Additional Oregon chub were introduced into Foster Pullout Pond in October 2000, to supplement the 85 fish introduced in 1999. In the summer of 2000, a habitat enhancement project creating new habitat to benefit Oregon chub was completed in the Long Tom drainage (Mid-Willamette River). Seven potential Oregon chub reintroduction sites were monitored and evaluated. These included four sites in the Mid-Willamette River drainage (Finley National Wildlife Refuge Beaver and Cattail Ponds, Ankeny National Wildlife Refuge Dunlin-Woodduck Pond, Long Tom Ranch Pond), one site in the Santiam River drainage (Menear's Bend Pond), one site in the McKenzie River drainage (Russell Pond), and one site in the Coast Fork Willamette drainage (Layng Pond). Estimates of abundance were obtained for naturally occurring populations of Oregon chub in East Fork Minnow Creek Pond, Shady Dell Pond, Elijah Bristow State Park Sloughs, Hospital Pond, Dexter Reservoir Alcoves, Buckhead Creek, Oakridge Slough, Santiam Conservation Easement Sloughs, Geren Island Ponds, and Finley Gray Creek Swamp. Five of these populations showed an increase in abundance in 2000 (East Fork Minnow Creek Pond, Shady Dell Pond, Middle Buckhead Creek, Dexter Reservoir Alcoves, Finley Gray Creek Swamp). Four populations decreased in abundance (or remain depressed) in 2000 (Geren Island, Santiam Conservation Easement, Elijah Bristow Sloughs, Oakridge Slough) (Table 1 ). Abundance estimates for introduced populations of Oregon chub were also obtained. The Oregon chub population in East Ferrin Pond declined from 7,200 fish in 1997 to O fish in 2000, and is presumed extinct. The Oregon chub population in the Fall Creek Spillway Pond totaled 5,030 fish in 2000, compared to 6,300 fish in 1999. The Oregon chub population in Wicopee Pond expanded dramatically from ~50 fish in 1999 to 4,580 fish in 2000. The Oregon chub population in the Dunn Wetland Ponds increased from 4,860 fish in 1999 to 14,090 fish in 2000. The Oregon chub population in Finley Display Pond increased from 360 fish in 1999 to 1,750 fish in 2000. Three of the four largest populations in 2000 were introduced populations. The Middle Fork Willamette River drainage supported the largest number of Oregon chub populations (n=12), followed by the Santiam drainage (n=B), and the Mid-Willamette drainage (n=5). The most abundant Oregon chub populations were found in the Middle Fork Willamette and Mid-Willamette drainages. The Oregon Chub Recovery Plan (U .S. Fish and Wildlife Service 1998) set a recovery goal for downlisting the species to "threatened" and for delisting the species. The criteria for downlisting the species was to establish and manage ten populations of at least 500 adult fish. All populations must exhibit a stable or increasing trend for five years. At least three populations must be located in each of the three sub-basins (Middle Fork Willamette River, Santiam River, Mid-Willamette River tributaries). In 2000, there were 11 populations totaling 500 or more individuals and six of these populations exhibited a stable or increasing trend for the past five years (Table 1 ). Five of these six populations were located in the Middle Fork Willamette drainage. In summary, Oregon chub remain at risk due to their limited distribution compared with their historic geographic range in the Willamette Valley, the loss of suitable habitat and the continued threats posed by the proliferation of non-native fishes, illegal water withdrawals, unauthorized fill and removal operations, and potential chemical spills or careless pesticide applications.

These ongoing monitoring programs provide technical, logistical, and biological information to managers charged with maintaining viable salmon and steelhead populations and associated fisheries in Northeast Oregon. This report summarizes fish culture monitoring data for LSRCP facilities for summer steelhead. These data serve as the basis for the analysis of trends in culture performance. Generally speaking, the data in this report were derived from hatchery inventories and standard databases (i.e., PSMFC, Coded-wire tag) or through standard measuring techniques. As such, specific protocols are usually not described. In cases where expansions of data or unique methodologies were used, protocols are described in more detail. Additional descriptions of protocols can be found in the 1999 and 2000 work statements (Carmichael et al. 1999a, Carmichael and Ruzycki 2000). Coded-wire tag (CWT) data that were collected from 1999-2000 adult returns were used to evaluate smolt-to-adult survival rates in experimental rearing and release groups. In 1999-2000, experimental treatments from which fish returned included acclimated vs. direct stream release, forced vs. volitional release, rearing site, growth, and density treatments. In 1999-2000, experimental treatments for which fish were released included forced vs. volitional, and pre-smolt release strategies. Analysis of specific survival studies will be completed once all brood years have returned and CWT data are complete for a given experiment. In addition, much of the data that we discuss in this report will be used in separate and specific evaluations of ongoing supplementation programs for steelhead in the Imnaha River basin. We began culture evaluations in 1983 and have dramatically improved many practices. Progress for work completed in previous years is presented in annual progress reports (Carmichael and Wagner, 1983; Carmichael and Messmer, 1985; Carmichael et al., 1986a, 1987, 1988a, 1988b, 1989, 1990, 1999b, 2004, 2005; Messmer et al., 1989, 1990, 1991, 1992, 1993; Flesher et al., 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1999; Whitesel et al., 1993; and Jonasson et al., 1994, 1995, 1996), United States v.

This report is organized into fish culture monitoring for juveniles, adults, CWT recoveries, and estimates for total escapement. During the period covered in this report, steelhead from the 1994-1997 broods returned to spawn, steelhead from the 1998 and 1999 broods were released as smolts, and adult steelhead that returned to spawn were used to create the 1999 and 2000 broods.

This “exercises” the salmon in the expectation that improving swimming ability will improve their survival during smolt migration, resulting in better survival to adulthood. We examined the effect of variable moderate flow rates (0.25-0.75 body lengths per second) on growth and physiology of juvenile chinook salmon Oncorhynchus tshawytscha and their ability to withstand acute stress, survive downstream migration and return as adults. Over the 5-8 month sampling period, mean length, weight and condition factor increased similarly in both the exercised and control groups. Mean plasma glucose levels were similar in each treatment group and peaked in early spring of each year. Hematocrit did not vary in a consistent trend for either treatment group or cohort. Hepatosomatic index (HSI) decreased in the 1994 cohort control group and increased in the 1995 cohort exercised group. In both cohorts, liver glycogen levels decreased through the winter and continued to decline in the 1994 cohort while in the 1995 cohort there was a significant peak in liver glycogen levels in each group during March 1997. Following stress, mean plasma glucose and cortisol levels increased, mean hematocrit varied inconsistently, mean HSI generally decreased, mean CSI decreased inconsistently in the 1995 cohort and mean liver glycogen level did not change. Mean survival of smolts to Lower Granite Dam did not vary between treatment groups with detection rates ranging narrowly from 58.7-60.7%. Mean percentage of adults returning at age 3 was higher for exercised salmon than for controls and a higher percentage of controls returned at age 5 than exercised salmon. Mean smolt-to-adult survival rate varied significantly between cohorts but there was no difference in mean survival rate between treatment groups. Variation within cohorts was greater between the exercised raceways than the controls, indicating that additional years of study are needed to compensate for large differences in survival between cohorts to make any conclusions regarding differences between treatments. Our results provide little evidence that rearing chinook salmon under a moderately increased and seasonally variable flow regime provided any benefit to the salmon over a steady low flow.

  Citation × Citation Citation Abstract Copy Title: Klamath Mountains Province Steelhead Project, 1999 Annual Report Report Number: OPSW-ODFW-2002-09 Abstract -- The steelhead supplement to the Oregon Plan for Salmon and Watersheds (OSPW) is intended to maintain wild steelhead populations in Oregon at sustainable and productive levels that provide substantial environmental, cultural, and economic benefits. The OSPW attempts to better define “sustainable and productive” by committing the Oregon Department of Fish and Wildlife (ODFW) to establish “Population Health Goals” for each Evolutionary Significant Unit (ESU) of wild steelhead within the state. In addition, section ODFW IB1S of the plan calls for ODFW to assess adult escapement and juvenile production of wild steelhead in each ESU. The National Marine Fisheries Service identified seven ESUs for steelhead in Oregon and concluded that steelhead produced in coastal basins between Cape Blanco in southern Oregon and the Klamath River Basin in northern California constitutes one ESU. This area closely corresponds to the geologic boundaries of the Klamath Mountains Province (KMP). Steelhead in the KMP differ from those in adjoining areas because of distinctive life history and genetic characteristics (Busby et al. 1994). Primary differences in life history parameters have been identified for wild KMP steelhead. Summer steelhead and winter steelhead differ in time of return as adults, tendency to return to fresh water on a false spawning migration (the “half-pounder” run), age at ocean entry, growth rate and migration patterns of juveniles in fresh water (ODFW 1990a; ODFW 1994). As a result of these differences, separate health goals seem warranted for summer and winter steelhead populations. Winter steelhead inhabit streams throughout the KMP, while summer steelhead are found only in a portion of the Rogue River Basin. However, the distribution of summer and winter steelhead overlap in major areas of the Rogue River Basin (Everest 1973) and as juveniles of the respective races cannot be differentiated, some population health goals will have to apply to both races. The status of wild steelhead in the Klamath Mountains Province ESU is not readily apparent. Busby et al. (1994) concluded that the steelhead in this ESU “is not now at risk of extinction, but if present trends continue, it is likely to become so in the foreseeable future”. In contrast, Chilcote (1998) concluded that almost all steelhead populations in the Oregon portion of the ESU “are relatively healthy and certainly do not warrant listing as threatened under the ESA”. Uncertainty as to the status of the resource, coupled with the comprehensive conservation plan developed by Oregon and the termination of wild fish harvest in all streams except the Rogue River, lead the National Marine Fisheries Service to defer a listing of KMP steelhead under the Endangered Species Act. However, KMP steelhead remained a candidate species during 1999. The goal of this project is to develop and implement assessment methods to determine the status of wild steelhead in the Oregon portion of the KMP. Project objectives include (1) develop population health goals and allied monitoring methods and (2) determine resource status in relation to health goals. Attainment of all of the population health goals will likely indicate that the populations of wild steelhead in the KMP are healthy and may allow managers to restore harvest opportunities for wild fish. Conversely, failure to attain any of the population health goals will likely indicate that the populations are depressed and would likely lead to actions designed to minimize fishing mortality. However, in most years it is likely that some goals will be attained while some will not be attained. Under that scenario, and depending on which goals are attained, selective fisheries, like the current one for wild winter steelhead in the Rogue River, remain as viable options for fishery managers.

The status of wild steelhead in the Klamath Mountains Province ESU is not readily apparent. Busby et al. (1994) concluded that the steelhead in this ESU “is not now at risk of extinction, but if present trends continue, it is likely to become so in the foreseeable future”. In contrast, Chilcote (1998) concluded that almost all steelhead populations in the Oregon portion of the ESU “are relatively healthy and certainly do not warrant listing as threatened under the ESA”. Uncertainty as to the status of the resource, coupled with the comprehensive conservation plan developed by Oregon and the termination of wild fish harvest in all streams except the Rogue River, lead the National Marine Fisheries Service to defer a listing of KMP steelhead under the Endangered Species Act. However, KMP steelhead remained a candidate species during 1999. The goal of this project is to develop and implement assessment methods to determine the status of wild steelhead in the Oregon portion of the KMP. Project objectives include (1) develop population health goals and allied monitoring methods and (2) determine resource status in relation to health goals. Attainment of all of the population health goals will likely indicate that the populations of wild steelhead in the KMP are healthy and may allow managers to restore harvest opportunities for wild fish. Conversely, failure to attain any of the population health goals will likely indicate that the populations are depressed and would likely lead to actions designed to minimize fishing mortality. However, in most years it is likely that some goals will be attained while some will not be attained. Under that scenario, and depending on which goals are attained, selective fisheries, like the current one for wild winter steelhead in the Rogue River, remain as viable options for fishery managers.

The OSPW attempts to better define "sustainable and productive" by committing the Oregon Department of Fish and Wildlife (ODFW) to establish "Population Health Goals" for each Evolutionary Significant Unit (ESU) of wild steelhead within the state. In addition, section ODFW IB1S of the plan calls for ODFW to assess adult escapement and juvenile production of wild steelhead in each ESU. The National Marine Fisheries Service identified seven ESUs for steelhead in Oregon and concluded that steelhead produced in coastal basins between Cape Blanco in southern Oregon and the Klamath River Basin in northern California constitutes one ESU. This area closely corresponds to the geologic boundaries of the Klamath Mountains Province (KMP). Steelhead in the KMP differ from those in adjoining areas because of distinctive life history and genetic characteristics (Busby et al. 1994). Primary differences in life history parameters have been identified for wild KMP steelhead. Summer steelhead and winter steelhead differ in time of return as adults, tendency to return to fresh water on a false spawning migration (the "half-pounder" run), age at ocean entry, growth rate and migration patterns of juveniles in fresh water (ODFW 1990; ODFW 1994). As a result of these differences, separate health goals seem warranted for summer and winter steelhead populations. Winter steelhead inhabit streams throughout the KMP, while summer steelhead are found only in a portion of the Rogue River Basin. However, the distribution of summer and winter steelhead overlap in major areas of the Rogue River Basin (Everest 1973) and as juveniles of the respective races cannot be differentiated, some population health goals will have to apply to both races.

This report summarizes the data collected during the summer of 2008 and, for coho salmon, compares it to data previously collected. The project originally surveyed only 1st-3rd order (tributary) streams but was expanded in 2002 to include juvenile steelhead (Oncorhynchus mykiss) and 4th-6th order (mainstem) rearing areas and in 2006 to the Oregon portion of the Lower Columbia River coho evolutionarily significant unit (ESU) (Figure 1). The sampling frame is intended to encompass all non-tidal coho and steelhead rearing habitat. The original 100k stream layer frame was replaced by a 24k frame in 2007. A Generalized Random Tessellation Stratified design (GRTS) (Stevens 2002) was used to create a spatially balanced, random point distribution. Sites were stratified by Monitoring Area (MA) and stream order (Table 1). A detailed description of the sampling frames and survey designs are found in Jepsen and Rodgers (2004) and Jepsen and Leader (2007). Field crews snorkeled all pools meeting the size criteria (6 m2 in surface area and 40 cm in maximum depth) in one kilometer of stream encompassing the GRTS point. Snorkeling was conducted during the minimum flow period from July to September using a single pass of one to four snorkelers, depending on stream width. In each pool counts were made of juvenile coho, Chinook, steelhead 90 mm, and cutthroat 90 mm. Presence was noted for dace, shiners, and trout < 90 mm. Sites with poor water clarity or quality were electrofished using a single pass without block nets to determine presence for coho, steelhead and cutthroat in each pool. To assess repeatability and quality control supervisory staff resurveyed 10% of tributary sites in each MA. Data were summarized by MA and stream order for analyses. Average pool density and percent pool occupancy for each site was averaged by MA. The percent of sites with at least one fish and with >0.7 coho/m2 are reported for each MA. 0.7 coho/m2 is regarded as full seeding after Nickelson et al. (1992) who reported full seeding based on electrofishing as 1.0 coho/m2 and Rodgers et al. (1992) who found that snorkelers observed 70% of the coho counted by electrofishing. CDFs, variances, and confidence intervals were created using tools developed by the EMAP Design and Analysis Team (EPA 2009).

  Citation × Citation Citation Abstract Copy Title: Status of Oregon Stocks of Coho Salmon, 2004 through 2008 Report Number: OPSW-ODFW-2009-3 Abstract -- This report summarizes five years of monitoring status and trend in Oregon’s naturally spawning coho salmon (Oncorhynchus kisutch) populations. The five coho run years reported are 2004 through 2008. Monitoring results include: abundance of naturally spawning coho; density of spawning coho; coho spawn timing; and proportion of hatchery (marked) coho in naturally spawning populations. These results are based on data from randomly selected spawning surveys, as well as other methods in areas without adequate random surveys. Results for coho standard spawning surveys, as well as spawning surveys for other species are covered in data summaries and reports posted on an Oregon Department of Fish and Wildlife (ODFW) web page (see: http://oregonstate.edu/dept/ODFW/spawn/index.htm). Monitoring occurs at three hierarchical spatial scales, as defined by the National Marine Fisheries Service (NMFS): Evolutionarily Significant Unit (ESU); Stratum; and coho Population. There are three coho ESU’s located entirely or partially within the State of Oregon: the Lower Columbia River (LCR) Coho ESU; the Oregon Coast (OC) Coho ESU; and the Southern Oregon/Northern California Coasts (SONCC) Coho ESU. This report summarizes results for coho populations in the portion of each ESU that is within the State of Oregon. In the Oregon portion of the LCR Coho ESU sufficient surveys were conducted to meet precision goals at the ESU level three out of the five sampling years. At the population complex scale, yearly precision goals were rarely met. Wild spawner abundance remained fairly stable over the five sampling years; hatchery abundance was more variable. Regional patterns in fish distribution, spawn timing, and hatchery proportion are apparent at both the stratum and population scale. In the Oregon Coast ESU sufficient surveys were conducted to meet precision goals at the ESU level in all five sampling years, however at the population scale, precision goals were rarely met. Wild spawner abundance declined over the first four sampling years, but showed a significant increase in the fifth sampling year. The proportion of hatchery fish was generally low, but variable over the five sampling years. Only two populations, Salmon River and North Umpqua River, consistently had over 10% hatchery fish on the spawning grounds. Regional patterns in fish distribution, spawn timing, and hatchery proportion are apparent. Inadequate funding and the need to update the GRTS sampling frame continue to hamper monitoring of the Oregon portion of the Southern Oregon/Northern California Coasts Coho ESU. In the Oregon portion of the ESU insufficient surveys were conducted to meet precision goals at the ESU level in any of the four years when GRTS surveys were done. However, estimates of wild coho spawners were obtained in all five years based on Huntley Park seining. Wild coho spawner abundance declined substantially over the five run years; but the proportion of hatchery coho spawning naturally was fairly low and stable. Regional patterns in fish distribution, spawn timing, and hatchery proportion are apparent.
