  Citation × Citation Citation Abstract Copy Title: Steelhead Escapement Monitoring in the Upper Grande Ronde River and Joseph Creek Basins - Annual Technical Report 2015 Abstract -- Summer steelhead in the Grande Ronde River basin fall within the Snake River Distinct Population Segment (DPS) and are listed as threatened under the Endangered Species Act (62 FR 43937; August 18, 1997). The Upper Grande Ronde River (UGRR) and Joseph Creek basins support two of the four populations in the Grande Ronde Major Population Group (MPG). These populations are segregated based on topographic, genetic, and behavioral evidence of interactions. Historically, the Grande Ronde River was one of the more significant anadromous fish producing rivers in the Columbia River basin. Despite recovery efforts, these populations remain depressed relative to historic levels. The goal of this project is to annually evaluate summer steelhead population abundance for the UGRR, and recently Joseph Creek, by conducting surveys of redds and spawning activity. These surveys provide those data needed to estimate adult steelhead escapement, improve our understanding of habitat utilization, and contribute to productivity and survival estimates for these populations.

  Citation × Citation Citation Abstract Copy Title: Lamprey Abstract -- The majority of scientific studies on lamprey have investigated biological attributes, with few studies investigating historic abundance, detailed distribution and specific ecological requirements and role. Because of the paucity of information and concerns of declining lamprey population in the Pacific Northwest, the Applegate River Watershed Council (ARWC) with the Medford District of the Bureau of Land Management (BLM) collaborated to study lamprey populations in the Applegate River watershed of southwest Oregon (Close et al. 1995, Larson & Belchik 1998, Kostow 2002). The objectives of the study included: (1) Identifying species composition; (2) determining the distribution of lamprey species; and (3) relating the distribution of lamprey ammocoetes (juveniles or larvae) to physical stream characteristics. This paper summarizes the life histories of the two most common lamprey species in the Oregon, the Pacific (Lampetra tridentata) and Western Brook (Lampetra richardsoni), details the methods of study, reports the results and summarizes the findings. Also included are recommendations and suggestions for future lamprey work in the Applegate basin.

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: Fish Research Project Oregon; John Day Basin Spring Chinook Salmon Escapement and Productivity Monitoring - Annual Report 2000 Abstract -- The John Day River subbasin supports one of the last remaining intact wild populations of spring Chinook salmon and summer steelhead in the Columbia River Basin. These populations, however, remain depressed relative to historic levels. Between the completion of the life history and natural escapement study in 1984 and the start of this project in 1998, spring Chinook spawning surveys did not provide adequate information to assess age structure, progeny-to-parent production values, smolt-to-adult survival (SAR), or natural spawning escapement. Further, only very limited information is available for steelhead life history, escapement, and productivity measures in the John Day subbasin. Numerous habitat protection and rehabilitation projects to improve salmonid freshwater production and survival have also been implemented in the basin and are in need of effectiveness monitoring. While our monitoring efforts outlined here will not specifically measure the effectiveness of any particular project, they will provide much needed background information for developing context for project-specific effectiveness monitoring efforts. To meet the data needs as index stocks, to assess the long-term effectiveness of habitat projects, and to differentiate freshwater and ocean survival, sufficient annual estimates of spawner escapement, age structure, SAR, egg-to-smolt survival, smolt-per-redd ratio, and freshwater habitat use are essential. We have begun to meet this need through spawning ground surveys initiated for spring Chinook salmon in 1998 and smolt PIT-tagging efforts initiated in 1999. Additional sampling and analyses to meet these goals include an estimate of smolt abundance and SAR rates, and an updated measure of the freshwater distribution of critical life stages.

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

Job 4 Summary: Our goal is to determine the factors important in limiting the production of wild and hatchery reared coho salmon in Oregon. Tasks for FY 1982: During FY 1982 we planned to: (1) prepare a review paper on past coho release strategies and develop recommendations for changes that may increase coho production from Oregon hatcheries; (2) complete all logistics and implement, the release of three groups of coho in the ocean release experiment; and (3) develop an historical data base of physical oceanographic factors that may influence coho salmon survival and growth. Accomplishments in FY 1982: An information report on coho release strategies was completed (Johnson 1982). The ocean release experiment was conducted in June 1982. We have obtained and tabulated historical records of upwelling indices, sea level measurements, sea surface temperature records, and spring upwelling transition dates.

These data describe areas of suitable habitat currently and historically used by Pacific lamprey populations. Pacific lamprey, Lampetra tridentata, (more recently identified as Entosphenus tridentatus), are native to the Pacific coast from Baja California to the Bering Sea. They are anadromous, migrating from their natal stream to the ocean and back, but unlike salmon, Pacific lamprey spend well over half of their total life cycle in freshwater. The Pacific lamprey was listed as an Oregon State sensitive species in 1993 and in 1996 was protected through restriction of harvest (ODFW 2006). These data now comply with the Oregon Fish Habitat Distribution Data Standard that was adopted by the Oregon Geographic Information Council in February 2011. The Standard document can be found at: http://gis.oregon.gov/DAS/EISPD/GEO/standards/docs/OregonFishHabitatDistributionDataStandardv2.pdf The term "currently" is defined as within the past five reproductive cycles. This information is based on sampling (see the fhdBasis field). Due to natural variations in run size, water conditions, or other environmental factors, some habitats identified may not be used annually.Habitat distribution data are mapped at a 1:24,000 scale statewide and are based on the Pacific Northwest Framework Hydrography dataset. The data are made available as GIS files in both shapefile and ESRI geodatabase format. The data were developed over an extensive time period ranging from 1990 to 2011. Data were migrated to the NHD in Spring of 2014.

  Citation × Citation Citation Abstract Copy Title: Draft - Trout and Warm Water Fish Running Waters Abstract -- Running Waters: Running waters include the main Rogue, Applegate, and Illinois rivers, and all associated tributary streams in the Rogue River basin. Historical information on trout in the Rogue River basin was summarized by Cole M. Rivers (in press) prior to 1962. Cutthroat and downstream migrating steelhead were abundant and easily caught from streams all through the settled portions of the basin. There was no need to take a trip away from home to fish for trout. Angling for trout was not thought of as a recreational pastime until the 1930s. The headwaters of the Applegate and Illinois rivers, and Jumpoff Joe and Grave creeks were preferred for trout fishing because of the easy access provided by mining roads. The California-Oregon Power Company provided access to trout fishing waters in the Prospect region as early as 1912. The completion of the Crater Lake and Diamond Lake highways in 1927 allowed access to the upper Rogue River and its tributaries. Access to other parts of the basin was provided when foot and wagon trails were made into roads by crews of the Civil Conservation Corps in the 1930's. Most natural lakes were devoid of fish life until they were stocked by miners or cattlemen who wanted a supply of trout close to their camps. Fish Lake was one of the first impoundments preferred for sport fishing because of good cattle trails leading from the Bear creek Valley into the area. Anglers were packed in by cattlemen after the dam was built in 1898. Other impoundments providing good trout fishing in the 1920s included Emigrant Lake which received heavy pressure. Many lakes were barren of fish life until rainbow, eastern brook, or cutthroat were packed in by private parties, the Forest Service, or the Oregon Game Commission in the 1920s. Prospectors and early settlers stocked some of the lakes earlier with fish that had been collected or salvaged from creeks that were drying up. There are no records of the unofficial introductions, and those of the Game Commission burned in a fire in 1936. Table 1 lists the liberations of trout recorded by the U.S. Bureau of Fisheries from 1907 to 1940.

Hazards include disease transfer, competition for food and spawning sites, increased predation, increased incidental mortality from harvest, loss of genetic variability, genetic drift, and domestication (Steward and Bjornn 1990; Hard et al. 1992; Cuenco et al. 1993; Busack and Currens 1995; NRC 1996; and Waples 1999). Hatcheries can also play a positive role for wild salmonids by bolstering populations, especially those on the verge of extirpation, providing a genetic reserve in the case of extirpation, and providing opportunities for nutrient enrichment of streams (Steward and Bjornn 1990; Cuenco et al. 1993). The objective of this project is to evaluate the potential effects hatchery programs on naturally spawning populations of Spring Chinook and winter Steelhead within the Upper Willamette River ESU. The project employs four types of activities to achieve this goal: sampling of returns to hatcheries, creels to assess fisheries, monitoring of adult and juvenile migration through the use of traps and video observations, and monitoring natural production through spawning ground surveys.

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.

  Citation × Citation Citation Abstract Copy Title: Willamette Biological Opinion Hatchery Research 2008 Interim Activities Report Abstract -- Possible risks of artificial propagation programs have been well documented. Hazards include disease transfer, competition for food and spawning sites, increased predation, increased incidental mortality from harvest, loss of genetic variability, genetic drift, and domestication (Steward and Bjornn 1990; Hard et al. 1992; Cuenco et al. 1993; Busack and Currens 1995; and Waples 1999). Hatcheries can also play a positive role for wild salmonids by bolstering populations, especially those on the verge of extirpation, by providing a genetic reserve as well as providing opportunities for nutrient enrichment of streams (Steward and Bjornn 1990; Cuenco et al. 1993). The objective of this project is to evaluate the potential effects of hatchery programs on naturally spawning populations of spring Chinook within the Upper Willamette River ESU. ODFW submits this report in fulfillment of Task Order NWPOD-08-FH-05 (per Task 3). This report covers activities of July 2008–May 2009 that were implemented by ODFW on behalf of the Corps to assist with meeting the requirements of the reasonable and prudent alternatives and measures prescribed in the Willamette Project Biological Opinion (BiOp) of July 2008 (NOAA 2008). Although a strategy to implement actions identified on the BiOp has not yet been completed, the Corps provided interim funding to continue certain monitoring activities and initiate long-term planning as detailed below: Task 1 (a–f). Monitor straying of hatchery fish on natural spawning grounds in the North Santiam, South Santiam, McKenzie, and Middle Fork Willamette rivers to determine the distribution, abundance and proportion of hatchery and natural-origin fish spawning by: (1) conducting spawning ground surveys downstream of projects and upstream of Detroit and Foster reservoirs; (2) conducting re-surveys to assess variability in redd counts among crews; (3) estimating pre-spawning mortality; (4) estimating the percentage of hatchery-origin spawners using otolith analysis; (5) monitoring fin-clipped and unclipped fish passing Leaburg and upper Bennett dams. Task 2 (a–c). Monitor fin-clipped and unclipped fish entering hatcheries and collection facilities (i.e., record number, origin, length, date of return); determine origin using otolith analysis; collect tissue samples for genetic analysis. Task 4. Work with Corps and/or contractors to develop coordinated monitoring plan for Corps-funded hatchery programs based on requirements in the 2008 BiOp.

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.

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. Abundance estimate trends that included shallow pools tracked with those based on the former pool criteria.

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. Abundance estimate trends that included shallow pools tracked with those based on the former pool criteria. Close

  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.

  Citation × Citation Citation Abstract Copy Title: NF - Sand Roller Investigations in the Willamette River Drainage, Annual Progress Report Abstract -- The purpose of this investigation was to determine the status and distribution of sand roller Percopsis transmontana populations in the Willamette River basin. Sand rollers are rare and endemic to the lower Columbia River drainage, including the Willamette River and its tributaries. Historical records are scarce. In 1945, R.E. Dimick and F. Merryfield found sand rollers to be localized in the Willamette River from Albany to Springfield, Santiam River, Rickreall Creek, Mary’s River, and the Coast Fork Willamette River. The Oregon State University museum collection has samples from the following Willamette River drainages: Coast and Middle Forks of the Willamette River, Mary’s River, Luckiamute River, Molalla River, Mill Creek, Long Tom River, and Santiam River. Their preferred habitat is quiet backwaters and pool margins of small to large rivers, usually near vegetation and woody debris over sand. The Oregon Department of Fish and Wildlife surveyed historic and recently documented locations in 2005 to determine the current status and distribution of sandrollers in the Willamette River basin. Sand rollers were collected from at least one location in most of the major Willamette River subbasins sampled.

This assessment combines the Brophy (2007) and Adamus (2005) approaches to quantify the extent and causes of habitat loss and hydrogeomorphic changes in tidal wetlands of four Oregon South Coast Estuaries. The potential for restoring critical habitat and wetland functions is ranked using Ecological Prioritization Criteria (Brophy, 2007), while indicators of function, risk, and integrity are evaluated using scoring models from the Adamus (2005) Hydrogeomorphic (HGM) Rapid Assessment Method. The extent of inundation (head of tide) during King Tide conditions was observed and documented by staff and volunteers. Field measurements of salinity concentrations and stratification during high and low flow were tabulated. The historic aerial photo record was examined to detect channel migration, floodplain re-vegetation, and human-caused alterations. Related studies were combined with these observations to provide a summary of estuary hydrology, sedimentation, and channel stability related to wetland establishment and loss in each of the four estuaries. Ecological priority scores (Brophy, 2007) varied with wetland size, tidal channel condition, connectivity, and diversity of vegetation classes. Wetlands were categorized as restoration or conservation types, and priority ranks for wetlands were depicted on orthophoto base maps. Tidal wetlands and nearby floodplain wetlands in a variety of geomorphic settings were surveyed using the HGM protocol, including one “reference” and one restoration site . The HGM survey scores 55 indicators, including botanical transects, used to rank wetland functions (calculated by indicator scoring models). Risks to wetlands include human disturbances in close proximity to the wetlands and floodplains, resulting from the narrow valley floors in this tectonically active region. Wetland integrity is threatened by a surprising large proportion of non-native species in the botanical transects, 40%. Wetland indicators that scored low, and could be restored or enhanced, are discussed in a restoration considerations narrative. Wetland descriptions include lists of plant species, grouped by wetland status, native/non-native, and perennial/annual persistence. In addition to the HGM scores, an analysis of cover and diversity of all plant species in plots, off-transect species diversity, and waterfowl food distribution was completed using a wetland vegetation database developed for the Oregon South Coast.

  Citation × Citation Citation Abstract Copy Title: Willamette Biological Opinion Hatchery Research 2010 Annual Report Abstract -- Task 1.1: Distribution, Abundance, and Proportion of Hatchery and Natural-Origin Chinook Salmon: Counts of spring Chinook redds were similar in 2010 compared to the 2002–2009 averages for the Middle Fork Willamette, McKenzie and the North Santiam rivers and significantly higher in the South Santiam River Preliminary analyses indicate that the proportions of hatchery fish recovered as carcasses from the spawning grounds varied significantly among all four surveyed sub-basins (South Santiam > M. Fork Willamette > North Santiam > McKenzie) Task 1.2: Monitor fin-clipped & unclipped fish passing Leaburg and Upper Bennett dams. Adult fish passage at Leaburg and Upper Bennett dams was continuously monitored in 2010. We estimated that 2,696 spring Chinook (52% unclipped) passed above Leaburg Dam and 5,956 passed above upper Bennett Dam (14% unclipped). Passage at Leaburg Dam of fin-clipped fish was strongly bimodal with peaks in June (coincident with passage of the majority of unclipped fish) and September (coincident with a smaller proportion of unclipped fish). This bimodal peak suggests that hatchery fish might be removed in September to reduce the proportion of hatchery origin spawners while simultaneously reducing the impacts of handling wild fish. Task 2.1: Collection, spawn timing, and Hatchery/Wild (H/W ) composition for broodstock management. Collection, spawn timing, and H/W composition for broodstock management were successfully monitored at all facilities in 2010. Task 2.2: Determine Survival of Outplanted Fish and Abundance of Spawners. Patterns of pre-spawning mortality were similar to results in 2009 with mortality below project dams significantly higher than that above project dams. We did not detect significant differences in mortality between clipped and unclipped spring Chinook. In comparisons of pre-spawning mortality among sub-basins above project dams, pre-spawning mortality was uniformly low in the Breitenbush and N. Santiam above Detroit, S. Santiam above Foster, and in the S. Fork McKenzie. Pre-spawning mortality was uniformly higher above project dams in the N. Fork Mid. Fork Willamette, Fall Creek and the Little N. Fork Santiam. No comprehensive surveys were conducted in the Middle Fork Willamette. Task 3.1: Determine the extent of summer steelhead reproduction in the wild: We developed a formal study plan to analyze and interpret genetic results from a collection of 299 tissue samples from unclipped juvenile steelhead at Willamette Falls, five from the mainstem Willamette River, and two from the South Santiam River in 2010 in addition to a single sample from an unclipped adult steelhead at the Minto fish collection facility. Samples were preserved 7 and cataloged and then shipped to the NOAA Fisheries Manchester, Washington (WA) laboratory for analysis. Task 3.2: Evaluate release strategies for summer steelhead to increase migration and reduce impacts on wild fish. Study plans to evaluate advantages and disadvantages of volitional release strategies were completed and presented in the 2009 annual report to USACE (Cannon et al. 2010). Funding to process the tissue samples was not available in 2010, and no progress was made in executing the proposed work.

These populations, however, remain depressed relative to historic levels. Between the completion of the life history and natural escapement study in 1984 and the start of this project in 1998, spring Chinook spawning surveys did not provide adequate information to assess age structure, progeny-to-parent production values, smolt-to-adult survival (SAR), or natural spawning escapement. Further, only very limited information is available for steelhead life history, escapement, and productivity measures in the John Day subbasin. Numerous habitat protection and rehabilitation projects to improve salmonid freshwater production and survival have also been implemented in the basin and are in need of effectiveness monitoring. While our monitoring efforts outlined here will not specifically measure the effectiveness of any particular project, they will provide much needed background information for developing context for project-specific effectiveness monitoring efforts. To meet the data needs as index stocks, to assess the long-term effectiveness of habitat projects, and to differentiate freshwater and ocean survival, sufficient annual estimates of spawner escapement, age structure, SAR, egg-to-smolt survival, smolt-per-redd ratio, and freshwater habitat use are essential. We have begun to meet this need through spawning ground surveys initiated for spring Chinook salmon in 1998 and smolt PIT-tagging efforts initiated in 1999. Additional sampling and analyses to meet these goals include an estimate of smolt abundance and SAR rates, and an updated measure of the freshwater distribution of critical life stages.

Between the completion of the life history and natural escapement study in 1984 and the start of this project in 1998, spring Chinook spawning surveys did not provide adequate information to assess age structure, progeny-to-parent production values, smolt-to-adult survival (SAR), or natural spawning escapement. Further, only very limited information is available for steelhead life history, escapement, and productivity measures in the John Day subbasin. Numerous habitat protection and rehabilitation projects to improve salmonid freshwater production and survival have also been implemented in the basin and are in need of effectiveness monitoring. While our monitoring efforts outlined here will not specifically measure the effectiveness of any particular project, they will provide much needed background information for developing context for project-specific effectiveness monitoring efforts. To meet the data needs as index stocks, to assess the long-term effectiveness of habitat projects, and to differentiate freshwater and ocean survival, sufficient annual estimates of spawner escapement, age structure, SAR, egg-to-smolt survival, smolt-per-redd ratio, and freshwater habitat use are essential. We have begun to meet this need through spawning ground surveys initiated for spring Chinook salmon in 1998 and smolt PIT-tagging efforts initiated in 1999. Additional sampling and analyses to meet these goals include an estimate of smolt abundance and SAR rates, and an updated measure of the freshwater distribution of critical life stages.

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 have to apply to both races. The status of wild steelhead in the Klamath Mountains Province ESU is not readily apparent from historic sources of information. Uncertainty about resource status, coupled with a comprehensive conservation plan developed by Oregon and the termination of wild fish harvest in almost all KMP streams, lead the National Marine Fisheries Service (NMFS), in 1998, to defer a listing of KMP steelhead under the Endangered Species Act. On 30 March, 2001, NMFS announced that, after a review of new information, that an Endangered Species Act listing was not warranted for KMP steelhead. In 2002, ODFW adopted new methods to monitor steelhead populations on the Oregon coast. Allied with the decision, ODFW decided to terminate the KMP steelhead project. Consequently, this report presents findings from the third, and final, year of the project. The goal of the project was to develop and implement assessment methods to determine the status of wild steelhead in the Oregon portion of the KMP. Project objectives included (1) develop population health goals and allied monitoring methods and (2) determine resource status in relation to health goals Satterthwaite (2002a). Directed sampling began in 1999 and findings from the first two years of the project were reported by Satterthwaite (2002b) and Satterthwaite (2003).

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

Hazards include disease transfer, competition for food and spawning sites, increased predation,increased incidental mortality from harvest, loss of genetic variability, genetic drift, and domestication (Steward and Bjornn 1990; Hard et al. 1992; Cuenco et al. 1993; Busack and Currens 1995; NRC 1996; and Waples 1999). Hatcheries can also play a positive role for wild salmonids by bolstering populations, especially those on the verge of extirpation, providing a genetic reserve in the case of extirpation, and providing opportunities for nutrient enrichment of streams (Steward and Bjornn 1990; Cuenco et al. 1993). The objective of this project is to evaluate the potential effects of hatchery programs on naturally spawning populations of spring chinook and winter steelhead within the Upper Willamette River ESU. The project employs four types of activities to achieve this goal: sampling of returns to hatcheries, creels to assess fisheries, monitoring of adult and juvenile migration through the use of traps and video observations, and monitoring natural production through spawning ground surveys.

  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.

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.

Results from 2014 are compared with results from previous years and used to 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. For prior reports visit https://nrimp.dfw.state.or.us/crl/default.aspx?pn=WORP. The Oregon Coast Coho (OCC) ESU density estimate in 2014 was lower than the recorded high estimate in 2013. 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. Occupancy estimates for the last 3 cohorts have been the lowest recorded since monitoring began. Pool population estimates were similar to 2013, but lower than in most years, with the exception of the estimates from 1998-2000. Lower Columbia River Coho (LCR) density, site occupancy, and pool population estimates were similar to 2013 and to the average since 2006. The Oregon Coast Steelhead DPS density estimate in 2014 was lower than 2013 but similar to the average from 2002-2013. Pool population estimates in 2014 were similar to 2013 and to the 2002-2013 average. The site occupancy estimate in 2014 was the highest recorded. The last four cohorts have had the four highest occupancy estimates. In the Klamath Mountain Province (KMP) DPS, steelhead density in 2014 was higher than the record low estimate in 2013 and similar to the DPS average from 2002-2013. The pool population estimate in 2014 was lower than 2013, but similar to the average from 2002-2013. Site occupancy was similar to 2013 and to the 2002-2013 average for the DPS. Steelhead density estimates in the LCR and the Southwest Washington (SWW) DPSs in 2014 were similar to each other, to averages for each DPS since 2006, and to the 2013 estimates. Site occupancy in 2014 for the LCR DPS was the highest recorded. In the SWW DPS site occupancy was similar to 2013 and to the 2006-2013 average estimates. Pool population estimates for LCR and SWW were similar to the 2006-2013 average of the estimates for the DPSs and to 2013 estimates. 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 produced larger pool population estimates with proportionately smaller confidence intervals than analyses based on the =40cm maximum depth criteria. Population estimate trends that included shallow pools tracked with those based on the former pool criteria.
