  Citation × Citation Citation Abstract Copy Title: Lower Umpqua Watershed Analysis, 1997 Abstract -- This analysis of the Lower Umpqua River watershed (2% of the total Umpqua River drainage area) in the southern Coast Range includes watershed characterization, issues, inherent landscape instability, aquatic species' habitat and population, terrestrial species' habitat and population, and restoration opportunities. 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.

  Citation × Citation Citation Abstract Copy Title: Spring Chinook Salmon in the Willamette and Sandy Rivers, October 2003 through September 2004 Abstract -- The Oregon Fish and Wildlife Commission adopted the Native Fish Conservation Policy (ODFW 2003a) and the Hatchery Management Policy (ODFW 2003b) in part to reduce adverse impacts of hatchery programs on wild native stocks. The Native Fish Conservation Policy recognizes that naturally produced native fish are the foundation for long-term sustainability of native species and hatchery programs, and the fisheries they support. In the past, hatchery programs and fish passage issues were the focus of spring Chinook salmon management in the Willamette and Sandy basins. Limited information was collected on the genetic structure among basin populations, on abundance and distribution of natural spawning, on rearing and migrating of juvenile salmon, or on strategies for reducing risks that large hatchery programs pose for wild salmon populations. This study was implemented to gather this information. Annual reports (available for 1996-2004 for this project) summarize data and are available at the above website.

Abstract -- Although the present size of the bull trout population within the Odell Lake Recovery Unit is unknown, it appears to be quite small. Spawning by bull trout of the Odell Lake Recovery Unit occurs only in the lower 0.8 km of Trapper Creek, below a falls presumed to be a barrier. Numbers of redds observed in Trapper Creek from 1996 through 2002 have ranged from one to 24. In addition to genetic effects caused by small population size, primary threats to the sustainability of these bull trout include limited spawning and rearing habitat in all streams, hybridization with brook trout in upper Trapper Creek, competition from other fish species, particularly lake trout in Odell Lake, and superimposition of kokanee salmon (O. nerka) redds on bull trout redds. The latter threat may be particularly detrimental because of the large number of kokanee that spawn in lower Trapper Creek. To address concerns of bull trout redd superimposition by bull trout, we designed studies to: 1) Assess the impacts to bull trout reproduction caused by kokanee that spawn at the same location, and 2) Develop acceptable methods to separate bull trout and kokanee that spawn in Trapper Creek, Odell Lake. The first objective will address the concerns that kokanee redds superimposed on bull trout redds will reduce the number of bull trout progeny. During the spawning season, we will cap several undisturbed bull trout redds and an equal number of redds superimposed with kokanee salmon redds. Emergent fry will be captured, identified, and enumerated; statistical comparisons of fry abundance will be made between both groups of redds. To adjust for spawner fecundity, estimates of the size of females that make each redd will be obtained visually. We intend to conduct these studies at Heising Springs on the Metolius River, which helps support one of the healthiest bull trout populations in Oregon. The second objective addresses efforts to enhance the Odell Lake bull trout population. Recently, managers installed a weir to block passage of kokanee salmon to spawning areas in Trapper Creek; bull trout were captured and placed upstream. This activity led to opposition by anglers supportive of kokanee and loss of adult bull trout by an otter that invaded the trap. Our intent is to help managers design and implement methods that 1) prevent kokanee salmon from impacting bull trout redds in Trapper Creek, 2) enable bull trout to move into and out of Trapper Creek without capture and handling, and 3) enumerate bull trout spawning in Trapper Creek. Data collected in Trapper Creek should help with design and implementation of methodologies to separate the species during the spawning season.

  Citation × Citation Citation Abstract Copy Title: Aquatic Habitat in Oregon Coastal Streams: Winter, 1999-2001 Abstract -- We compared summer and winter aquatic habitat conditions to determine patterns of seasonal habitat dynamics for coho salmon (Oncorhynchus kisutch). Winter sites corresponded to summer sites, facilitating a direct comparison between seasons on a site specific and regional scale. The data sets included 128 sites selected from the Oregon Plan habitat sites (OPHS) surveyed in the summers of 1999 and 2000 and surveyed again in the winters of 2000 and 2001. We found significant differences among geomorphic, hydrologic, and physical habitat variables measured along identical reaches in streams between winter and summer. Increases in water volume corresponded with increased deep pool density, secondary channel habitats, and wood density. These differences highlight the importance of high winter flows in terms of their contribution towards essential habitat for coho survival and reproduction. Differences among habitat variables from consecutive winters were minimal, indicating that any differences in habitat variables may be a result of variation in annual precipitation. Moreover, minimal differences in habitat variables were observed between Basin and OPHS surveys, also leading to the suggestion that OPHS surveys, conducted during the summer may provide important baseline information on habitat variables within and among watersheds. Habitat quality, as measured by benchmarks, was shown to be independent of land ownership but not independent of monitoring area. This investigation allowed us to quantify seasonal changes in summer-to-winter habitat dynamics in coastal Oregon streams. Future research could involve the addition of juvenile salmon surveys with habitat surveys to determine any significant associations between fish density and habitat quality. Furthermore, habitat variables measured during the summer might be used to determine winter habitat conditions (i.e. and thus quality), after accounting for variation in annual precipitation. Attribute means and estimates of variation, measured at identical sites in summer and winter over the long-term, may be beneficial when linking summer to winter habitat variables and ultimately to fish density estimates, thereby increasing sample size and predictability.

  Citation × Citation Citation Abstract Copy Title: 2000-2002, Effectiveness Monitoring for the Western Oregon Stream Restoration Program Abstract -- This report characterizes change in habitat conditions of restoration projects competed by Western Oregon Stream Restoration Program biologists. Typical restoration activities included the placement of large wood and/or boulders in stream channels, removal of culvert passage barriers, riparian planting, road decommissioning, and streamside fencing. Implementation occurred coast-wide and in the Willamette Valley, with an overall goal of enhancing aquatic habitat for salmonid species. This program works in cooperation with the Oregon Heritage Foundation, Oregon Department of Forestry, US Fish and Wildlife Service, US Forest Service, industrial and private landowners, and watershed councils. Projects that were implemented in 2000 and 2001 were monitored to assess baseline pre-treatment and one-year post-treatment conditions. Additionally, projects that were treated in 1995 were monitored in 1996 to assess one-year post-treatment conditions and in 2001 to assess six-year posttreatment conditions. The objectives of the monitoring program were to describe changes in channel morphology, channel unit composition, and structural complexity in the restoration project areas.

  Citation × Citation Citation Abstract Copy Title: Salmon, Steelhead and Bull Trout (SSBT) Pre-cursor Layer for Western Oregon Abstract -- This dataset represents both a derivation and synthesis of seven Oregon Fish Habitat Distribution datasets (winter steelhead, summer steelhead, coho salmon, spring Chinook, fall Chinook, chum salmon and Bull Trout) into a single SSBT dataset to support forestry related water protection rules. Stream reaches were filtered to include only the currently accessible habitat for the aforementioned species within the four Oregon Dept. of Forestry georegions in western Oregon: Western Cascade, Interior, Coast Range and South Coast. Basis categories were generalized into the following categories: observation-based or opinion-based. Observation based records include those records with a basis of: "Documented Observation of Fish" or observations of fish made during a protocol based survey, "Undocumented Observation of Fish" or observations of fish made during a non-protocol based survey, "Documented Observation of Habitat" or observation of habitat during a protocol based survey, and "Downstream of Documented Observation of Fish". Opinion based records include only those records which have a "Concurrence of Professional Opinion" amongst multiple fisheries biologists. The Oregon Fish Habitat Distribution Data Standard includes descriptions of these basis categories as well as the rules required for implementing updates. Data were synthesized into this single GIS dataset by selecting the "highest" record basis present across all 7 datasets. If an observation based record occurred within any one of the seven datasets, it was retained. If no observation based records were present across all seven species, the record was identified as opinion based. These data include all ODF stream size classes and also all ownerships and will be processed further by the Oregon Dept. of Forestry to identify where SSBT stream reaches occur on small and medium streams and on private lands in Western Oregon. Original source data are referenced to the National Hydrography Dataset (NHD). In some rare cases, records for different species describing the same stream reach may be represented by different stream geometry due to mapping that referenced different versions of the NHD.

The term "currently" is defined as within the past five reproductive cycles. Historical habitat includes suitable habitat that fish no longer access and will not access in the foreseeable future without human intervention. This information is based on sampling, the best professional opinion of Oregon Dept. of Fish and Wildlife or other natural resources agency staff biologists or modeling (see the fhdBasis field). Due to natural variations in run size, water conditions, or other environmental factors, some habitats identified may not be used annually. These data now comply with the Oregon Fish Habitat Distribution Data Standard that was adopted by the Oregon Geographic Information Council in June 2015. The Standard document can be found at: http://www.oregon.gov/DAS/CIO/GEO/fit/bioscience/docs/OregonFishHabitatDistributionDataStandardv3.pdf. Historical habitat distribution data are within the scope of the standard and are identified via the habitat use (fhdUseType) attribute. Historical habitats are only identified outside of currently accessible habitat and are not comprehensive. Key features of the Oregon Fish Habitat Distribution Data include: species, run, life history, habitat use, origin, production, the basis for each record, originator name, originator entity and reference. Habitat distribution data are mapped at a 1:24,000 scale statewide and are based on the National 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 1996 to 2017. The data were recently migrated to USGS managed, Hydrography Event Management (HEM) tool compliant, event feature class format based on the National Hydrography Dataset.

Evidence from this project and across the range of coho strongly indicates that connectivity in diverse and dynamic tidal habitats provides alternative rearing pathways critical for the sustainability and recovery of Oregon Coastal (OC) coho stocks. Specifically, this project reestablished innovative PIT tag mark recapture techniques to monitor coho movements and migrations. Temporal and spatial components of over-winter rearing strategies, in relation to habitat use and project effectiveness monitoring, is the focus in these paired study streams. Notably, monitoring was shifted to Willanch Creek from Larson Creek. Juvenile coho diet analyses revealed seasonal and diurnal variation in foraging strategies between early migrating sub-yearlings and yearling smolts across their range in estuarine habitats. These results reveal the fundamental mechanisms that promote increased juvenile coho growth and survival in the estuarine ecotone. In conjunction with prior and current data, results highlight the critical importance of these diverse habitats for recovering viable OC coho populations.

The study objectives were to provide information on juvenile Chinook salmon distribution, relative growth rate, predator/prey interactions, and other population characteristics. In addition, we tested the feasibility of various gear-types and techniques for sampling juvenile Chinook salmon rearing in a reservoir environment. A variety of techniques were necessary to capture juvenile Chinook salmon as reservoir conditions and fish behavior, size, and distribution within the reservoir changed throughout the year. Nighttime snorkel surveys were the least invasive and most productive method to investigate habitat utilization and fry distribution early in the Spring. Minnow traps, hoop nets, Lampara seining, and mid-water trawling were largely ineffective at sampling fry and larger-sized juveniles. Oneida Lake trap nets were the most effective at capturing larger-sized juvenile Chinook salmon when reservoir surface temperatures remained cool.

  Citation × Citation Citation Abstract Copy Title: Willamette Biological Opinion Hatchery Research 2002 Annual 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; 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.

  Citation × Citation Citation Abstract Copy Title: Willamette Biological Opinion Hatchery Research 2002-2005 Final Report Abstract -- RECOMMENDATIONS 1. The number of hatchery Chinook spawning with wild fish upstream of Leaburg Dam should be reduced. The percentage of carcasses from hatchery fish in spawning areas upstream of the dam averaged over 30% in 2001–2004, with percentages exceeding 60% in the South Fork McKenzie River and areas downstream. The number of hatchery adults could be reduced by reducing the number of hatchery smolts released in the McKenzie River, by excluding hatchery adults from passing Leaburg Dam, by increasing the percentage of returning hatchery fish that home to the hatchery, or by a combination of these actions. 2. The number of hatchery and naturally produced Chinook spawning naturally, the number and distribution of redds and age at return of naturally produced Chinook should be determined annually for each of the Chinook populations in the Upper Willamette ESU. 3. Video recording systems should be installed at Bennett dams on the North Santiam and at Lebanon Dam on the South Santiam to count adipose clipped and non fin-clipped Chinook, and winter steelhead. 4. The extent and causes of pre-spawning mortality of Chinook in the North Santiam, South Santiam and Middle Fork Willamette rivers should be determined. High pre-spawning mortality in these rivers could limit natural production. 5. Rearing and release methods for hatchery spring Chinook smolts should be evaluated and modified to reduce straying by returning adults to streams other than where they were released. Rearing and release strategies for hatchery Chinook should be evaluated (e.g., outmigration and use of rearing habitat) for potential effects on wild juvenile chinook. 6. The number of naturally produced Chinook incorporated into hatchery broodstocks should be monitored by collecting and analyzing otoliths of non fin-clipped fish. 7. The number of Chinook fry consumed by hatchery rainbow trout in the McKenzie River could be substantial and needs to be determined. 8. Restricting the trout season in Foster Reservoir to late April or late May through October and delaying releases of hatchery trout would better protect wild steelhead smolts, and would be consistent with regulations for North Fork Reservoir (Clackamas River) where there is a fishery for stocked trout and naturally produced steelhead smolts are also present. 9. Samples should be collected from wild steelhead smolts in the North Santiam and South Santiam to determine the extent of natural reproduction by summer steelhead and genetic introgression with native winter steelhead.

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.

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.

  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 hatchery stocks, as well as all naturally spawned spring Chinook salmon in the Upper Willamette Basin, are included in the Upper Willamette River Evolutionary Significant Unit (ESU). The Upper Willamette Summer Steelhead Hatchery Program is managed to provide fish for sport fisheries and to replace loss of fisheries caused by habitat and passage loss/degradation in the Willamette Basin and other lower Columbia basins. Summer steelhead are not native to the Willamette Basin upstream of Willamette Falls. Summer steelhead were first brought into the South Santiam River as mitigation for lost winter steelhead production in areas inundated by Foster and Green Peter reservoirs. The hatchery program currently includes annual smolt releases into the North Santiam, McKenzie, and Middle Fork Willamette rivers. Because summer steelhead are not native to the upper Willamette Basin and could interact negatively with ESA-listed species, the Willamette Project Biological Opinion (BiOP; NMFS 2008) required the USACE to collect information to describe the nature and extent of these potential effects.

This report fulfills a requirement under Task Order W9127N-12-2-0004-1009 covering activities of May 2013–June 2014, that were implemented by ODFW on behalf of the Corps to assist with meeting requirements of the reasonable and prudent alternatives (RPAs) and measures prescribed in the Willamette Project Biological Opinion (BiOp) of July 2008 (NOAA 2008). The Corps provided funding to continue ongoing monitoring activities and initiate long-term planning. The conceptual relationship between spring Chinook salmon prioritized objectives, RPAs, and 2013 work tasks is depicted in Figure 2. In future work, the intent is to expand the conceptual framework provided in Figure 2 and develop specific numerical goals in terms of, for example, adult returns desired per subbasin. A detailed list of tasks associated with the work is provided in Appendix 1. Close

The goal of this project was to provide information on spawning distribution of winter steelhead above and below Foster Dam considering the influence of upstream fish passage and outplanting procedures. Data were collected by conducting spawning ground surveys throughout the South Santiam subbasin using a spatially-balanced design during the 2015/2016 and 2016/2017 spawning seasons. During the 2016/2017 season additional surveys were conducted explicitly to determine the amount of overlap between winter-run and non-native, hatchery summer-run steelhead on the spawning grounds. Generally, both summer- and winter-run steelhead spawned in the upper reaches of streams and near Foster Dam. There was a six-week separation between the end of summer-run spawning and the onset of winter-run spawning. Outplanting methods for both runs have been consistent since at least 2006 and we found no evidence of negative impacts of the program on prespawn mortality. The spatiallybalanced survey design resulted in a threefold increase in miles surveyed compared to traditional index surveys and provided information regarding the distribution of spawning activity in the South Santiam subbasin that was lacking. The South Santiam River does not have any fish counting stations and, other than fish volitionally entering the trap at Foster Dam, there is no way to know how many fish enter the subbasin. Continued spawning ground surveys, a video monitoring system at Lebanon Dam, or both are needed to monitor these ESA-listed fish in the subbasin and evaluate the possible negative effects of the hatchery program and outplanting procedures.

  Citation × Citation Citation Abstract Copy Title: Willamette BiOp - Genetic Stock Identification and Relative Natural Production of Willamette River Steelhead Abstract -- We used genotypic data from 15 microsatellite loci to characterize the stock structure of Oncorhynchus mykiss in the upper Willamette River basin. We then used two analytical approaches, implemented in the programs ONCOR and STRUCTURE, to assign (presumably) natural-origin, unmarked fish to their most likely reporting group or hybrid class. We investigated sibling relationships among unknown samples with the program ML RELATE. In the upper Willamette River, O. mykiss genetic structure can be characterized by four principal groups: summer steelhead of Skamania stock ancestry, eastern tributaries winter steelhead, western tributaries winter steelhead and resident rainbow trout. We found that about 10% of unmarked juvenile O. mykiss sampled at Willamette Falls in 2009-2011 were summer steelhead and that an additional 10% of samples were summer x winter steelhead hybrids. Most O. mykiss sampled from the McKenzie River were either summer steelhead or summer x winter steelhead hybrids. Natural production of pure summer steelhead appeared to be very low in the North and South Santiam rivers, though summer steelhead hybrids represented 11.1% and 14.8% of samples. Results from ML RELATE analyses appeared unreliable and inconclusive, and may have been limited by low genetic diversity among summer steelhead samples. We provide several recommendations to better understand and reduce potentially negative interactions between hatchery summer steelhead and native upper Willamette River O. mykiss populations. These include reductions in adult steelhead on natural spawning grounds, improved reproductive isolation between hatchery and native populations and additional research to evaluate genetic integrity within and among O. mykiss populations.

Information Reports Number 2010-03 Abstract -- Fishery managers are commonly tasked with the basic question "Will the contemporary habitat above a barrier support the fish populations that historically resided in the watershed?" Managers in central Oregon were confronted with that question in an effort to reestablish fish populations in 375 kilometers of stream above the Round Butte-Pelton Dam complex (Rkm 161) on the Deschutes River. Stream surveys had been conducted in most of the available stream habitat, but had not been synthesized in a form that allowed managers to view the quality and complexity of stream habitat in an easily-understandable fashion. In response, we developed a limiting factors model (HabRate) that assessed the potential quality of stream habitat using stream survey data for each juvenile life stage of salmon and steelhead. The model was developed for a specific application to the middle Deschutes River basin in Oregon, but was intended for general application to Pacific Northwest basins. To paramatize the model, we summarized available literature on salmonid habitat requirements. Habitat criteria were developed for discrete life history stages (i.e. spawning, egg survival, emergence, summer rearing, and winter rearing) and used to rate the quality of stream reaches as poor, fair, or good, based on attributes relating to stream substrate, habitat unit type, cover, gradient, temperature, and flow. Reach level summaries of stream habitat data were entered into MS Excel, and interpreted by a series of algorithms to provide a limiting factor assessment of potential egg-to-fry and fry-to-parr survival for each reach. Model output lists habitat quality by species and life stage for each reach of stream. The model is a decision making tool that is intended to provide a qualitative assessment of the habitat potential of stream reaches within a basin context. Design criteria for the model were simplicity, flexibility, and transparency. While HabRate was based on our interpretations of the published literature, specific criteria for habitat quality were structured to be easily adjusted where interpretations differ from ours. Information not common to standard stream survey designs, such as seasonal flow or temperature extremes can be included as input from professional judgment. The results were integrated into a GIS coverage coupled with the stream network and habitat data to provide a comprehensive map-based perspective of habitat quality in a watershed.

  Citation × Citation Citation Abstract Copy Title: Columbia River Basin - System Configuration Study; Snake River Drawdown, Migratory Canal, Upstream Collector Planning Aid Report Abstract -- This Planning Aid Report (PAR) is provided to the U.S. Army Corps of Engineers, Walla Walla District, to assist with reconnaissance-level planning for the System Configuration Study (SCS), which is a component of the Columbia River Salmon Mitigation Analysis (CRSMA). A preliminary draft and draft of the PAR were circulated for review and comment, and comments have been incorporated or addressed in the PAR. The SCS is evaluating physical changes to the configuration of the Columbia River System for the purpose of improving survival for anadromous fish. The proposed changes include modification of spillways, powerhouses and associated structures on the lower Snake River, and the construction of additional dams and structures which would permit modifications in present system operation. This specific PAR addresses the lower Snake River drawdown alternatives and the upstream collection and transport alternatives, including the migratory canal and tube. In addition, specific requests have been made from the Columbia-Snake River Drawdown Committee to evaluate designs for a side-channel spi 11 way and downstream weir at each of the lower Snake River projects. These elements were not addressed in the preliminary draft of the PAR. Other elements of SCS, such as the John Day drawdown and upstream storage, are being addressed by the Portland and Boise Fish and Wildlife Ecological Services Offices of the U.S Fish and Wildlife Service. The objectives of this PAR are to: 1) Describe relevant fish and wildlife populations and habitat within the study area; 2) Describe future fish and wildlife habitat conditions without the project; 3) Appraise existing fish and wildlife utilization; 4) Evaluate impacts of project alternatives on fish and wildlife resources; 5) Identify data gaps and study needs which need to be addressed during feasibility; and 6) Identify potential mitigation opportunities and requirements. In order to evaluate a full range of alternatives to improve the survival of anadromous fish stocks in the Snake River, this PAR also recommends that alternatives to evaluate the removal of one to four dams on the lower Snake River, and permanent, partial drawdowns be included in the range of alternatives under consideration. The need to consider these alternatives has become evident as uncertainties associated with the initially proposed alternatives have developed.

This program was funded by Bonneville Power Administration and was managed under the Fisheries Program, Department of Natural Resources, Confederated Tribes of the Umatilla Indian Reservation. An estimated 36.7 km (22.6 miles) of stream habitat were inventoried on the Umatilla River, Moonshine, Mission, Cottonwood and Coonskin Creeks. A total of 384 of 3,652 (10.5%) habitat units were electrofished. The number of juvenile fish captured follows: 2,953 natural summer steelhead (including resident rainbow tout; Oncorhynchus mykiss), one hatchery steelhead, 341 natural chinook salmon (0. tshawytscha), 163 natural coho salmon (0. kisutch), five bull trout (Salvelinus confluentus), 185 mountain whitefish (Prosopium williamsoni), and six northern squawfish (Ptychocheilus oregonensis). The expanded population estimate for the areas surveyed was 73,716 salmonids with a mean density of 0.38 fish/m2. The following number of non-salmonids were visually estimated: 7,572 speckled dace (Rhinichthys osculus), 5,196 sculpin (Cottus spp.), 532 suckers (Catostomus spp.) and 191 redside shiners (Richardsonius balteatus). The gross estimated density of all non-salmonids combined was 0.84 fish/m2. The estimated ratio of non-salmonids to salmonids was 2.4: 1. Relative salmonid abundance, seasonal distribution and habitat utilization were monitored at index sites throughout the basin. During index site monitoring, the following species were collected in addition to those listed above: american shad (Alosa sapidissima), smallmouth bass (Micropterus dolomieu), carp (Cyprinus Carpio) and chiselmouth (Acrocheilus alutaceus). Thirty ­nine sites were electrofished during the spring and summer seasons, while 36 sites were sampled in the fall season. Index sites with the. highest mean salmonid catch/minute (fish/min.) during the three sample periods were located at the following sites: East Birch Creek (3.4 fish/min.), Boston Canyon Creek (3.2 fish/min.), Spring Creek (3.1 fish/min.) and upper Squaw Creek (3.0 fish/min.). The highest electrofishing catch rates were observed in the Umatilla River tributaries above river mile (RM) 70 in the August and September sample period (Table J-2 catalogs river miles with associated landmarks). During the November sample period, catch rates were highest in Birch Creek tributaries. Most salmonids were captured in slow water near the bank during the November and March sampling periods. A study of the migration movements and homing requirements of adult salmonids in the Umatilla River was conducted during the 1994-95 return years. Radio telemetry was used to evaluate the movements of adult salmonids past diversion dams in the lower Umatilla River and to determine migrational movements of salmonids following upstream transport. Radio transmitters were placed in 30 summer steelhead, 15 spring chinook, nine fall chinook, and eight coho salmon. Salmon were released at Three Mile Falls Dam (TMD). An additional 11 summer steelhead and ten spring chinook salmon were tagged, hauled upstream, and released at either Barnhart, Nolin, Thornhollow, or Imeques C-mem-ini-kem. On average, summer steelhead required 36 days to successfully migrate from TMD to Stanfield Dam. Spring chinook required 18 days. Average passage times for summer steelhead (hours and minutes) at Westland, Feed Canal, and Stanfield Dams were 13:06, 83:24, and 2:58, respectively. Spring chinook salmon required 04:30 at Westland, 89:42 at Feed Canal, and 04:01 at Stanfield Dams. Migrational delays were observed at Feed Canal Dam at flows ranging from 563 to 1,601 cubic feet/second (cfs). Thirty-eight percent of the fish ladder at Westland Dam, 75% at Feed canal, and 31% at Stanfield Dam. Average passage times at Feed Canal Dam (1995) were more than 15 times those at Stanfield Dam in 1994 and more than 20 times those at Stanfield Dam in 1995. Data related to homing and passage needs of Umatilla River salmonids was investigated in an attempt to maximize homing to the Umatilla River. Straying rates of adult summer steelhead and spring chinook salmon were found to be low while coho and fall chinook salmon stray rates were high in some groups, particularly adult returns from subyearling smolt releases of fall chinook salmon. Attraction flows of from the mouth of the Umatilla River of at least 150 cfs were required to encourage migration and reduce straying of fall chinook and coho salmon. Significant numbers of summer steelhead entered when flows exceeded 500 cfs. Spring chinook salmon entry was variable with fish entering at flows ranging from 150 to more than 2,000 cfs. Adult anadromous salmonids potentially available to spawn above TMD from August 26, 1994 to June 27, 1995 included: 593 adult and 530 jack fall chinook salmon (1994 brood), 879 adult and 54 jack coho salmon (1994 brood), 784 natural and 509 hatchery summer steelhead (1995 brood), and 378 adult and 62 jack spring chinook salmon (1995 brood). During escapement surveys (fall of 1994), a total of 82 fall chinook salmon redds, 24 coho salmon redds and seven unidentified salmon redds (112 redds total, 2.6/mile) were enumerated along 42.3 miles of the mainstem above TMD. In 1995, we enumerated and flagged 126 summer steelhead redds (3.6 redds/mile) along 35.3 miles of lateral tributaries of the Umatilla River. Also enumerated were 90 spring chinook salmon redds (1.6 redds/mile) along 55.8 miles of the mainstem. Ninety-six percent of the adult fall chinook salmon carcasses examined had spawned while 94% of the coho had spawned; 66.8 % of the spring chinook salmon carcasses examined bad spawned. A total of 49.3% of spring chinook salmon released above TMD were sampled during spawning ground surveys and 60 coded wire tags (CWTs) were recovered from 78 adipose clipped fish. The rotary screw trap in the Umatilla River (RM 76) operated 63 of 113 days from September 21, 1994 to January 13, 1995. The trap captured 596 juvenile steelhead with a mean trap efficiency rate of 9.9%. A total of 1,368 juvenile chinook salmon were captured with a mean trap efficiency rate of 28. 8 % . The rotary screw trap at the Imeques C-mem-ini-kem site (RM 79.5) operated 43 out of 43 days from May 5 through June 16, 1995. The trap captured 304 natural juvenile steelhead with a mean trap efficiency rate of 6.6%. A total of 102 natural juvenile chinook salmon were captured with a mean trap efficiency rate of 10.5%. The rotary screw trap at the Barnhart site (RM 42,2) operated 87 out of 125 days from March 3 to June I, 1995. The trap captured 105 natural juvenile steelhead, 247 natural juvenile chinook salmon, five natural coho salmon, 6,265 hatchery juvenile chinook salmon, 467 hatchery steelhead and 16,844 hatchery coho salmon. Mean trap efficiency rates ranged from 2.3 to 5.7% . Harvest monitors estimated that tribal anglers harvested 25 hatchery and five natural summer steelhead during the spring of 1995. There was no spring chinook salmon fishery in the Umatilla River during 1995 because of the low number of returning adults. Scale analysis determined that over 85 .0% of naturally produced juvenile summer steelhead sampled during biological and index surveys were age O+ or l +. Naturally produced summer steelhead adults, returning to the Umatilla River in 1994-95, were mostly from the 1990 (46.4%) and 1991 (33.9%) brood years.

Spring chinook salmon required 04:30 at Westland, 89:42 at Feed Canal, and 04:01 at Stanfield Dams. Migrational delays were observed at Feed Canal Dam at flows ranging from 563 to 1,601 cubic feet/second (cfs). Thirty-eight percent of the fish ladder at Westland Dam, 75% at Feed canal, and 31% at Stanfield Dam. Average passage times at Feed Canal Dam (1995) were more than 15 times those at Stanfield Dam in 1994 and more than 20 times those at Stanfield Dam in 1995. Data related to homing and passage needs of Umatilla River salmonids was investigated in an attempt to maximize homing to the Umatilla River. Straying rates of adult summer steelhead and spring chinook salmon were found to be low while coho and fall chinook salmon stray rates were high in some groups, particularly adult returns from subyearling smolt releases of fall chinook salmon. Attraction flows of from the mouth of the Umatilla River of at least 150 cfs were required to encourage migration and reduce straying of fall chinook and coho salmon. Significant numbers of summer steelhead entered when flows exceeded 500 cfs. Spring chinook salmon entry was variable with fish entering at flows ranging from 150 to more than 2,000 cfs. Adult anadromous salmonids potentially available to spawn above TMD from August 26, 1994 to June 27, 1995 included: 593 adult and 530 jack fall chinook salmon (1994 brood), 879 adult and 54 jack coho salmon (1994 brood), 784 natural and 509 hatchery summer steelhead (1995 brood), and 378 adult and 62 jack spring chinook salmon (1995 brood). During escapement surveys (fall of 1994), a total of 82 fall chinook salmon redds, 24 coho salmon redds and seven unidentified salmon redds (112 redds total, 2.6/mile) were enumerated along 42.3 miles of the mainstem above TMD. In 1995, we enumerated and flagged 126 summer steelhead redds (3.6 redds/mile) along 35.3 miles of lateral tributaries of the Umatilla River. Also enumerated were 90 spring chinook salmon redds (1.6 redds/mile) along 55.8 miles of the mainstem. Ninety-six percent of the adult fall chinook salmon carcasses examined had spawned while 94% of the coho had spawned; 66.8 % of the spring chinook salmon carcasses examined bad spawned. A total of 49.3% of spring chinook salmon released above TMD were sampled during spawning ground surveys and 60 coded wire tags (CWTs) were recovered from 78 adipose clipped fish. The rotary screw trap in the Umatilla River (RM 76) operated 63 of 113 days from September 21, 1994 to January 13, 1995. The trap captured 596 juvenile steelhead with a mean trap efficiency rate of 9.9%. A total of 1,368 juvenile chinook salmon were captured with a mean trap efficiency rate of 28. 8 % . The rotary screw trap at the Imeques C-mem-ini-kem site (RM 79.5) operated 43 out of 43 days from May 5 through June 16, 1995. The trap captured 304 natural juvenile steelhead with a mean trap efficiency rate of 6.6%. A total of 102 natural juvenile chinook salmon were captured with a mean trap efficiency rate of 10.5%. The rotary screw trap at the Barnhart site (RM 42,2) operated 87 out of 125 days from March 3 to June I, 1995. The trap captured 105 natural juvenile steelhead, 247 natural juvenile chinook salmon, five natural coho salmon, 6,265 hatchery juvenile chinook salmon, 467 hatchery steelhead and 16,844 hatchery coho salmon. Mean trap efficiency rates ranged from 2.3 to 5.7% . Harvest monitors estimated that tribal anglers harvested 25 hatchery and five natural summer steelhead during the spring of 1995. There was no spring chinook salmon fishery in the Umatilla River during 1995 because of the low number of returning adults. Scale analysis determined that over 85 .0% of naturally produced juvenile summer steelhead sampled during biological and index surveys were age O+ or l +. Naturally produced summer steelhead adults, returning to the Umatilla River in 1994-95, were mostly from the 1990 (46.4%) and 1991 (33.9%) brood years. Close

  Citation × Citation Citation Abstract Copy Title: The Oregon Conservation Strategy, 2006 Abstract -- State and federal agencies, as well as other organizations, have developed and led many plans during the years to guide conservation of Oregon's fish and wildlife and their habitats. Most of these plans have focused on a particular species, area or natural resource. Although wildlife conservation often has been an implicit concern of these plans, many were developed primarily for other purposes. With the creation of this Oregon Conservation Strategy, Oregon has its first overarching state strategy for conserving fish and wildlife. The Conservation Strategy is an effort to use the best available science to create a broad vision and conceptual framework for long-term conservation of Oregon's native fish and wildlife, as well as various in­vertebrates and native plants. As a guide to conserving the species and habitats that have defined the nature of Oregon, this strategy can help ensure that Oregon's natural treasures are passed on to future generations. The Conservation Strategy emphasizes proactively conserving declining species and habitats to reduce the possibility of future federal or state listings. It is not a regulatory document, but instead presents issues and opportunities, and recommends voluntary actions that will improve the efficiency and effectiveness of conservation in Oregon. Healthy fish and wildlife populations require adequate habitat, which is provided in natural systems and, for many species, in landscapes managed for forestry, agriculture, range and urban uses. The goals of the Conservation Strategy are to maintain healthy fish and wildlife populations by maintaining and restoring functioning habitats, preventing declines of at-risk species, and reversing declines in these resources where possible. These goals fit well with ODFW's statutory obligation to protect and enhance Oregon's fish and wildlife and their habitats for use and enjoyment by present and future generations. However, this is not a management plan for the Oregon Department of Fish and Wildlife. Instead, it is a broad strategy for all of Oregon, offering potential roles and opportunities for residents, agencies and organizations. It incorporates information and insights from a broad range of natural resources assessments and conservation plans, supple­mented by the professional expertise and practical experiences of a cross-section of Oregon's resource managers and conservation interests. It is designed to have a variety of applications both inside and outside of state government. Most important, perhaps, it establishes the basis for a common understanding of the challenges facing Oregon's fish and wildlife, and provides a shared set of priorities for addressing the state's conservation needs. The heart of the Conservation Strategy is a blueprint for voluntary action to address the long-term needs of Oregon's fish and wildlife. The future for many species will depend on landowners' and land managers' willingness to voluntarily take action on their own to protect and improve fish and wildlife habitat. The strategy outlined in this document considers fish and wildlife from a statewide perspective, establishing a broader context for decisions about the species and habitats in greatest need of conservation attention. It also recognizes that these issues vary in different regions, requiring conservation actions to be tailored to the unique needs of the fish, wildlife and human communities that coexist throughout Oregon. Much good work already is being done by private landowners. water-shed councils, conservation organizations and agencies like the many soil and water conservation districts. This strategy continues building on the solid foundation these groups have set for Oregon's conservation future. This document is called a strategy, not a plan, because its purpose is to help people make decisions more strategically about how they can invest time and resources in fish and wildlife conservation. To that end, the Conservation Strategy focuses on a suite of species and habitats, many of them closely linked, that are in greatest need of conservation attention. The strategy provides guidance on the types of actions most likely to benefit these species and habitats, and describes a variety of non-regulatory programs that can help landowners and land managers with implementation. For agencies and organizations working on a larger scale, the Conservation Strategy highlights specific geographic "Conservation Opportunity Areas" that provide good opportunities to address the conservation needs of high-priority habitats and species. These landscape-scale areas include both public and private ownership where targeted investments in conservation actions and incentives for private landowners are likely to generate the greatest long-term benefits for fish and wildlife. The expanding footprint of human development and 150 years of landscape alteration have left much of Oregon's fish and wildlife at varying degrees of risk. For example, the song of Oregon's state bird, the western meadowlark, is rarely heard in the Willamette Valley any more. A grassland bird still common in eastern Oregon, the meadowlark is not going to be a candidate for listing under the Endangered Species Act any time soon. But the state bird is in trouble across a significant portion of its historic range in Oregon. Like most of Oregon's wildlife, it retains a natural resilience and will respond to improved habitat conditions. However, the meadowlark needs some conservation attention. For the western meadowlark and dozens of other similarly vulnerable species including fish, amphibians, reptiles, mammals, invertebrates and plants, the Oregon Conservation Strategy offers hope for a more secure future.

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: Information Report Number 2006-02; Analysis of Factors Potentially Inflating the Marine Survival Estimate of Coho Salmon (Oncorhynchus kisutch) at Mill Creek, Yaquina River, Central Oregon Coast Abstract -- Scale and otolith analyses were used to determine if high marine survival estimates observed for coho salmon at an Oregon Department of Fish and Wildlife Life Cycle Monitoring Project site are inflated by 1) adult coho that reared as juveniles in other tributaries straying to the site, or 2) coho dispersing out of the site as fry, rearing in nearby salt marsh habitat, then returning to the site to contribute to the adult population. Scale analysis indicated that adult straying from other tributaries in the basin was unlikely to be contributing to the high marine survival estimate at the site. Scale analysis also indicated no evidence that coho fry rearing in nearby salt marshes were smolting as age-0+ fish and returning to contribute to the adult spawner population. Analyses of otolith strontium profiles were unable to distinguish differences in habitat use for fish reared in freshwater and marsh habitat because of aberrantly high ambient strontium to calcium abundance in the freshwater environment. Therefore the method was unsuitable for determining if coho fry rearing in nearby salt marshes were smolting as age-1+ fish and returning to contribute to the adult spawner population.

  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.

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.

  Citation × Citation Citation Abstract Copy Title: Implementation of the Environmental Monitoring and Assessment Program (EMAP) Protocol in the John Day Subbasin of the Columbia Plateau Province - Technical Report 2004 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, 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.

Degraded floodplain and channel structure, altered sediment routing, altered hydrology, and water quality (temperature) are cited as limiting factors in the Draft Mid-Columbia Steelhead Recovery Plan (Carmichael 2008). Current and proposed restoration efforts for the MFJDR_IMW are anticipated to address these key limiting factors. In order to assess restoration effectiveness on focal fish species, monitoring and analyses must emphasize population level spatial scales. Fish population monitoring for the MFDJR_IMW includes evaluating summer steelhead and spring Chinook population productivity, survival, and abundance. While abundance is an important metric for population assessments, survival and production will also be key indicators of population responses to planned restoration activities. Freshwater survival is assessed from the parr to smolt life stages (parr to smolt survival) and ocean or out-of-basin survival is estimated as a smolt to adult return ratio (SAR). Freshwater productivity is assessed as smolts produced for constructed redds (smolts/redd). Originator: ODFW, Eastern Oregon Fish Research (EOFR). Funded by Oregon Watershed Enhancement Board (OWEB).

We investigated the patterns of travel time and survival of hatchery and natural smolts fitted with passive integrated transponder (PIT) tags through specific reaches of the migration corridor during the 2000–2006 migration years for two populations originating in the Grande Ronde River basin (Lostine River and Catherine Creek). For both populations, median travel times for natural smolts were significantly longer in the upper reaches of the migration corridor but shorter in the lower reaches than for their hatchery counterparts. Also, among both hatchery and natural smolts, smaller individuals spent more time in the upper reaches, presumably feeding to attain a larger size before continuing their migration. Within populations, both hatchery and natural smolts showed similar patterns of survival through the reaches of the migration corridor above Lower Granite Dam. Size-selective mortality was evident for hatchery and natural smolts from both populations, especially in the upper reaches, larger individuals experiencing higher survival. The Catherine Creek population experienced the majority of natural and hatchery smolt mortality (32.8–65.8%) in a relatively short (91-km), low-gradient reach immediately below the summer rearing habitat. In contrast, the Lostine River natural and hatchery smolts experienced lower mortality (3.6–46.1%) in a 174-km reach below the summer rearing habitat. The results of this study demonstrate the dynamic nature of survival and migration rate among spring Chinook salmon smolts during their initial seaward migration from tributaries.

However, little quantitative information has been available to fisheries biologists and studies to quantify total annual escapement have not been conducted. Techniques used to estimate spawning escapement were often not documented (Van Cleave and Ting 1960, Oregon Fish Commission, unpublished data; Smith 1975). While other estimates have formed the basis for compensating losses due to the construction of the lower Snake River dams and setting subbasin supplementation goals, the accuracy of these estimates is unknown (USACE 1975, Carmichael and Boyce 1987, ODFW 1990). As populations continue to decline, accurate historic and current escapement estimates are needed to set management goals for conservation, recovery, supplementation, harvest, and to monitor population health. Spawning populations of spring/summer Chinook salmon have been monitored in Northeast Oregon streams since 1948 by visually counting redds. The Oregon Fish Commission established early surveys and in 1961 the Oregon Game Commission also began surveys. The two agencies were merged into the Oregon Department of Fish and Wildlife in 1975. In the past, time and budget limitations prevented fishery biologists from surveying entire streams. Redd counts, therefore, were limited to only a portion of the available spawning habitat on each stream termed the “index” area. The index area was chosen as the area most likely to provide a good sample (represent majority of spawning) of spawning escapement for a given stream.

Natural escapement declines in the Grande Ronde Basin have been severe and parallel those of other Snake River populations. Reduced productivity has primarily been attributed to increased mortality associated with downstream and upstream migration past eight dams and reservoirs in the Snake and Columbia rivers. Reduced spawner numbers, combined with human manipulation of previously important spawning and rearing habitat in the Grande Ronde Basin, have resulted in decreased spawning distribution and population fragmentation of chinook salmon in the Grande Ronde Basin (Figure 1; Table 1). Escapement of spring/summer chinook salmon in the Snake River basin included 1,799 adults in 1995, less than half of the previous record low of 3,913 adults in 1994. Catherine Creek, Grande Ronde River and Lostine River were historically three of the most productive populations in the Grande Ronde Basin (Carmichael and Boyce 1986). However, productivity of these populations has been poor for recent brood years. Escapement (based on total redd counts) in Catherine Creek and Grande Ronde and Lostine rivers dropped to alarmingly low levels in 1994 and 1995. A total of 11, 3 and 16 redds were observed in 1994 in Catherine Creek, upper Grande Ronde River and Lostine River, respectively, and 14, 6 and 11 redds were observed in those same streams in 1995. In contrast, the maximum number of redds observed in the past was 505 in Catherine Creek (1971), 304 in the Grande Ronde River (1968) and 261 in 1956 in the Lostine River (Tranquilli et al 2003). Redd counts for index count areas (a standardized portion of the total stream) have also decreased dramatically for most Grande Ronde Basin streams from 1964 - 2002, dropping to as low as 37 redds in the 119.5 km in the index survey areas in 1995 from as high as 1,205 redds in the same area in 1969 (Table 1). All streams reached low points (0-6 redds in the index areas) in the 1990's, except those in which no redds were found for several years and surveys were discontinued, such as Spring, Sheep and Indian creeks which had a total of 109 redds in 1969.

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.
