  Citation × Citation Citation Abstract Copy Title: Grande Ronde Basin Spring Chinook Salmon Hatchery Review: Introduction and The Early Years - 2011 Abstract -- This paper provides background information, program development history, and assessment of early program performance of the Grande Ronde basin spring Chinook salmon Lower Snake River Compensation Plan (LSRCP) hatchery program. We cover the period from initiation of the program in the late 1970s through the late 1990s, when significant hatchery reform measures were implemented in response to ESA listing and other policy influences. Separate papers are presented that review the recent performance of the Upper Grande Ronde River, Catherine Creek and the Lostine River Spring Chinook hatchery programs. The Grande Ronde basin historically supported diverse and robust populations of Chinook salmon Oncorhynchus tshawytscha. Abundant runs supported tribal and recreational fisheries throughout the basin. The recreational fisheries closed in the mid-1970s due to the depressed status of the populations and limited tribal fishing occurred from the mid-1970s - 1990s.

We compared run timing using arrival time at the weir and found that natural salmon arrived earlier than hatchery salmon in 12 of 14 years. Natural carcasses, of either or both sexes, were recovered earlier than hatchery carcasses for all years combined and during 6 of 14 years, indicating earlier spawning by natural salmon. We compared spawning distribution using the percent of female carcasses recovered in each spawning ground survey reach. A greater percent of natural female carcasses were recovered in reaches above the weir and further upstream than carcasses of hatchery-reared females, which were more commonly found in reaches closer to and below the weir. Management strategies designed to maintain the genetic integrity and life history characteristics of the Imnaha River Chinook salmon should be considered, implemented and evaluated. Collected broodstock should mimic the wild run and spawn timing. Release strategies should be developed to promote a broader spatial spawning distribution of returning hatchery adults.

In contrast, the total escapement of coho salmon has remained virtually unchanged, averaging 1,447 fish in 1987-91, reflecting an increase in hatchery fish returns. Wild fish currently compose 8.9% of the coho salmon counted at Marmot Dam. A shift in peak time of arrival in November in 1960-66 to a peak time of arrival in October in subsequent years is indicative of the increase in early-run hatchery fish and commensurate decline of late-run wild fish in the run. The loss in production of wild fish is likely the result of competition and introgression with.hatchery fish that have been extensively transplanted above Marmot Dam since 1964.

Summer run steelhead and resident trout are the most important species to the local recreational fishery, although significant numbers of spring, summer, and fall chinook are also taken from the river. The salmon contribute significantly to fisheries in the Pacific Ocean and Columbia River and steelhead enter fisheries in the Columbia. The Deschutes also supports a good population of whitefish, lesser numbers of other trout species, small runs of coho and sockeye salmon, and several species of nongame fish.

Also summarized are the associated broodstock monitoring data collected at weirs in the Grande Ronde Basin that are operated by our co-managers, the Nez Perce Tribe (NPT; Lostine River) and Confederated Tribes of the Umatilla Indian Reservation (CTUIR; Catherine Creek and Upper Grande Ronde River). The main objectives of this report are to document and evaluate spring Chinook Salmon culture performance for hatchery programs and achievement of management objectives in the Imnaha and Grande Ronde river basins (CTUIR and NPT have specific program goals for Chinook returns to Catherine Creek, the Upper Grande Ronde River, Lookingglass Creek, and the Lostine River that are discussed and evaluated in separate reports prepared by each co-management agency). Overall, these data are used to modify salmon culture practices, as needed, in order to optimize egg-to-smolt survival rate, smolt quality, and smolt-toadult survival rate, and monitor spawning in nature by hatchery-reared salmon. This report provides information on rearing and release operations for brood year (BY) 2011 of juvenile Chinook Salmon smolts, the collection of eggs for BY 2013, numbers and characteristics of mature Chinook Salmon in the 2013 return year, the 2013 spawning year at Lookingglass Fish Hatchery and in nature, bacterial kidney disease (BKD), and survival information (e.g., SAR, R:S) for BY 2008. These metrics document the success of these programs in meeting the LSRCP objectives for mature salmon returning to the mitigation area above Lower Granite Dam (LGD) and for harvest below LGD. In order to avoid confusion around whether jacks (age 3) are included with adult metrics, we will use the convention that “adults” include only ages 4 and 5 and “total” or “mature salmon” include all identifiable sexually mature salmon ages 3–5.

The main objectives of this report are to document and evaluate spring Chinook Salmon culture performance for hatchery programs and achievement of management objectives in the Imnaha and Grande Ronde river basins (CTUIR and NPT have specific program goals for Chinook returns to Catherine Creek, the Upper Grande Ronde River, Lookingglass Creek, and the Lostine River that are discussed and evaluated in separate reports prepared by each co-management agency). Overall, these data are used to modify salmon culture practices, as needed, in order to optimize egg-to-smolt survival rate, smolt quality, and smolt-toadult survival rate, and monitor spawning in nature by hatchery-reared salmon. This report provides information on rearing and release operations for brood year (BY) 2011 of juvenile Chinook Salmon smolts, the collection of eggs for BY 2013, numbers and characteristics of mature Chinook Salmon in the 2013 return year, the 2013 spawning year at Lookingglass Fish Hatchery and in nature, bacterial kidney disease (BKD), and survival information (e.g., SAR, R:S) for BY 2008. These metrics document the success of these programs in meeting the LSRCP objectives for mature salmon returning to the mitigation area above Lower Granite Dam (LGD) and for harvest below LGD. In order to avoid confusion around whether jacks (age 3) are included with adult metrics, we will use the convention that “adults” include only ages 4 and 5 and “total” or “mature salmon” include all identifiable sexually mature salmon ages 3–5.

  Citation × Citation Citation Abstract Copy Title: Comprehensive Plan for Production and Management of Oregon's Anadromous Salmon and Trout: Coastal Chinook Salmon Plan Abstract -- This is the fourth in a series of individual species plans concerning management of anadromous salmonid populations in the state of Oregon. This plan focuses on the actions the agency will take regarding chinook salmon Oncorhynchus tshawytscha populations produced in Oregon Coastal watersheds from the Necanicum River in the north to the Winchuck River at the Oregon-California border. Management of chinook salmon in the Columbia River basin is shaped by a cooperative agreement with the state of Washington, the Columbia River Treaty Indian Tribes, and the Federal Government. This management plan for wild and hatchery coastal chinook salmon in coastal river basins is the product of an ongoing planning process. The process began with the preparation of a report that contains descriptions of the life histories and assessments of recent trends in the run strengths of chinook salmon stocks in Oregon coastal river basins (Nicholas and Hankin 1988). ODFW staff and public representatives developed a comprehensive list of issues of concern and actions needed to improve management of coastal chinook salmon. These actions were based in part on a review of historic and contemporary habitat, harvest, and enhancement management practices in Oregon and on a review of the fisheries scientific literature.

We cover the period from program initiation in 1982 to the present (2010). The Imnaha River basin historically supported an abundant run of spring/summer Chinook salmon. Tribal and recreational fisheries occurred throughout the basin. Recreational fisheries were closed in the mid-1970s due to the depressed status of the population and tribal fishing was limited in many years.

  Citation × Citation Citation Abstract Copy Title: Part IV. Anadromous Fish Production Plans Abstract -- Early-returning coho salmon in the Sandy Subbasin are produced at the Sandy Hatchery and managed as a hatchery stock. They also produce naturally in numerous tributaries and the upper mainstern. Numbers for early-run coho that return to spawn naturally are represented best by Marmot Darn counts. Although some spawning habitat for coho exists below Marmot Darn, the optimum tributaries are above the darn in upper tributaries and side channels of the mainstem. Construction of Marmot Dam and the Bull Run Reservoir system has reduced the available habitat historically used by coho salmon. Although Marmot Darn is laddered, flows for many years after construction were not adequate to attract or allow passage above the dam. Minimum flow agreements now maintain flows adequate for fish passage and attraction. The Bull Run River remains blocked for anadrornous fish passage above the dam for Reservoir 2; the city of Portland mitigates for the loss of habitat by funding the release of juvenile fish elsewhere in the subbasin.

We compared run timing based on arrival time at the weir and found that naturally reared Chinook salmon arrived earlier than hatchery-reared fish in all 16 years. Carcasses of naturally reared fish of either or both sexes were recovered on the spawning grounds earlier than carcasses of hatchery-reared fish for all years combined and during 5 of 16 years, indicating earlier spawning by naturally reared fish. We compared spawning distribution using the percent of female carcasses recovered in each spawning ground survey reach. The percent recovery of the carcasses of naturally reared females was greater in reaches above the weir than below the weir and these carcasses were farther upstream than those of hatchery-reared females. For females of hatchery origin, carcasses were more commonly found in reaches closer to and below the weir (the smolt release location). Alternate management strategies designed to improve the maintenance of genetic integrity and life history characteristics of the Imnaha River Chinook salmon population should be considered, implemented, and evaluated. Collection strategies should be modified to ensure that the hatchery broodstock is representative of the entire natural run, and release strategies should be developed to promote a spawning distribution of hatchery adults that mimics the distribution of natural imnaha Chinook salmon.

  Citation × Citation Citation Abstract Copy Title: Chinook Salmon Recreational Fishery Creel Survey on Lookingglass Creek for the 2001 Run Year Abstract -- In 2001, a large number of hatchery origin Chinook salmon Oncorhynchus tshawytscha, 1,717, were expected to return to Lookingglass Creek. Most of the projected returns were from the Rapid River stock, a non-native hatchery stock of salmon that was no longer in use in the basin due to its non-local origin and high stray rates. Concern over potential disease transmission to Endangered Species Act listed stocks of Chinook salmon being reared at Lookingglass Fish Hatchery led to a management decision to not allow Chinook salmon spawning above the hatchery and to limit spawning to a short section of stream below the hatchery water intake. Because most returning Chinook salmon were from a stock that was no longer in use in hatchery programs in the basin and co-managers had decided that it was undesirable that they spawn in the wild, co-managers decided to remove as many as possible from the stream by providing recreational and tribal fishing opportunities. Recreational angling for Chinook salmon was allowed on Lookingglass Creek from 26 May through 1 July 2001. An intensive creel survey was conducted to monitor angling effort, catch rates and impacts on nontarget stocks and species. We conducted 1,606 angler interviews during the 2001 season on Lookingglass Creek. We estimate that 741 Chinook salmon were caught and 541 were kept by anglers. Catch rates were good throughout the season with mean catch rates of 12.0 and 12.3 h/fish in May and June, respectively, and 8.7 h/fish on 1 July.

  Citation × Citation Citation Abstract Copy Title: Life History Variability, Habitat Use, and Migratory Behavior of Coastal Cutthroat Trout in the Salmon River, Oregon Report Number: OPSW-ODFW-2012-10 Abstract -- Coast basins in Oregon support resident and anadromous cutthroat trout (Oncorhynchus clarki clarki). Cutthroat trout isolated above barriers are stream resident, but those with access to river, estuary, and marine environments may express a variety of life history and migratory patterns. Past studies (e.g. Giger 1972, Sumner 1972, Tipping 1981) indicated that estuaries serve primarily as a migratory corridor or short-term rearing environment. However, recent advances in marking and tracking technology have permitted researchers to gain a better understanding of the complex migratory and habitat use patterns of cutthroat. Krentz (2007) conducted studies in Salmon River on the central Oregon coast to explore migratory patterns of cutthroat and examine the role of the estuary as a rearing environment. Coastal cutthroat trout reared for extended periods of time throughout the available channel habitats in Salmon River estuary (Krentz 2007) during spring, summer, and fall. The estuarine resident population appeared to represent a significant portion of the migratory individuals, and included all older age classes. Estuary growth was similar to that of their ocean migrant counterparts, and survival in the estuary was high. Because cutthroat were collected and marked primarily within the estuary (Krentz 2007), it is unclear what portion of the migrant population reared in the estuary relative to the watershed or ocean, or whether the tagged group was representative of the migratory populations. The current study was designed to track a representative sample of the downstream migrant population, and assess the relative success (survival) of the estuary and ocean migrants. Similar studies in the Columbia River documented directed and rapid migration through the estuary (Zydlewski et al. 2008, Hering et al. 2009). With rare exception, cutthroat trout were not observed to rear in the estuary. In addition, many fish disappeared before reaching the ocean and few of the ocean migrants returned to the natal tributary. In this study we replicated the study design used in the Columbia River studies to further comparisons of estuary migration and rearing strategies between the two estuaries. The primary objective of our work in the Salmon River was to increase understanding of coastal cutthroat trout biology and the relationship between stream-resident and migratory, or “sea-run” cutthroat. Here we use the term “sea-run” to indicate migration into the tidally-inundated, or estuarine portions of the Salmon River watershed or to the ocean. Study objectives were to: 1.Estimate the distribution and abundance of coastal cutthroat trout in the Salmon River watershed 2.Quantify the proportions of the cutthroat populations that are migratory, identify which individuals migrate and describe the timing of migration 3.Describe estuary habitats used by sea-run migrants and characterize behavior within the Salmon River estuary 4.Estimate growth rate of stream and estuary resident cutthroat 5.Estimate estuary and ocean survival of sea-run individuals and document return to estuary and lower river. 6.Compare migratory behavior in Salmon River to that observed in the lower Columbia River Title: Life History Variability, Habitat Use, and Migratory Behavior of Coastal Cutthroat Trout in the Salmon River, Oregon Report Number: OPSW-ODFW-2012-10 Abstract -- Coast basins in Oregon support resident and anadromous cutthroat trout (Oncorhynchus clarki clarki).

  Citation × Citation Citation Abstract Copy Title: Lower Snake River Compensation Plan; Oregon Spring Chinook Salmon Harvest Monitoring - 2016 Annual Progress Report Abstract -- The Imnaha and Grande Ronde River spring Chinook hatchery programs are components of the Lower Snake River Compensation Plan (LSRCP), funded through the U.S. Fish and Wildlife Service (USFWS), developed to mitigate for wild fish production lost as a result of construction of the four lower Snake River dams. Hatchery Chinook and steelhead smolts in the Snake River basin are produced at LSRCP hatcheries in Washington, Idaho and Oregon. Subsequent adult returns are meant to provide tribal and recreational (sport) fisheries and, in some cases, enhance natural spawner numbers. The Oregon Department of Fish and Wildlife (ODFW) initiated the Imnaha and Grande Ronde spring Chinook hatchery program in 1982 under the LSRCP. Subsequent program management has been coordinated between ODFW, the Confederated Tribes of the Umatilla Indian Reservation (CTUIR), and the Nez Perce Tribe (NPT). The Imnaha and Grande Ronde River hatchery programs are comprised of five components, each with smolt acclimation and adult collection facilities located on the Imnaha River, upper Grande Ronde River, Lookingglass and Catherine Creeks, and the Lostine River. The Lostine River program interacts with natural production within the broader Wallowa-Lostine population unit. Other hatchery program components are discrete to specific populations indicated. The Lookingglass Creek portion of the program focuses on reintroduction of spring Chinook to that stream and targets the release of 250,000 smolts, annually. Each of the four remaining program components integrates natural-origin fish returning to each respective tributary into production. Smolt release goals, developed to meet LSRCP mitigation responsibilities; include 490,000 for the Imnaha, 250,000 for the Lostine and upper Grande Ronde rivers, and 150,000 for Catherine Creek. Fisheries that target returns to the Imnaha and Grande Ronde hatchery programs are guided by Fishery Management and Evaluation Plans (FMEP), approved by NOAA fisheries under limit 4 of the final 4(d) rule of the Endangered Species Act (ODFW 2011, ODFW and WDFW 2012). The objective of the FMEP is to provide recreational fishing opportunities and related benefits derived from harvest of Imnaha and Grande Ronde basin hatchery-origin spring Chinook salmon in Oregon and Washington in a manner that supports the continued survival and future recovery of natural-origin Chinook salmon. Each respective FMEP utilizes a management framework for harvest of adipose-clipped, hatchery-origin Snake River spring/summer Chinook salmon using abundance-based sliding scales to set annual fishery impacts. Fisheries are prescribed maximum impact rates for both direct and incidental mortality of natural-origin adult salmon in sport and tribal fisheries. Impacts are assessed for each population in relation to critical and minimum abundance thresholds (MAT) as described by the Interior Columbia Technical Recovery Team (ICTRT 2007). Population designations for the Imnaha and Grande Ronde Basins are listed in Table 1, and are based upon an analysis of Chinook salmon life history traits, distribution, abundance, and productivity, and geographical and ecological characteristics of the landscape within the Snake River Spring/Summer Chinook Salmon ESU (McElhany et al. 2000). The abundance-based harvest rate schedule for Imnaha and Grande Ronde Basin fisheries to be shared by all fishing entities in the basin as described in Table 2. Harvest is not considered when hatchery run size does not exceed the number of adults identified for broodstock and supplementation needs as described by sliding scale management plans set for each population’s hatchery program. Surplus is generally defined as the adult hatchery run projection less hatchery adults needed for broodstock. This approach limits sport harvest during years when wild fish runs are below MAT and hatchery fish runs are of similar size. In addition, near the lower end of the harvest rate scale, fisheries are not implemented until the allowable hatchery fish harvest exceeds 20 fish due to potential to over harvest within a single week. Fishery impacts to listed Snake River spring/summer Chinook salmon are assessed on a collective basis (i.e., the sum of recreational and tribal fisheries) by NOAA fisheries. However, the coordination of impact amongst states and tribes is a key component of executing conservation-based fisheries in the Imnaha and Grande Ronde Basins. Co-managers within each basin have developed, and implement annually, an impact sharing agreement that is described in Table 3. Within each fishery scenario, this agreement provides tribal fisheries more of the natural-origin impacts to reflect the non-selective nature of traditional fishing techniques. Recreational fisheries are provided a larger portion of the hatchery harvest such that all available impacts (hatchery and natural collectively) are shared equally (Table 3). Recreational fisheries administered by the states limit harvest (retention) of spring/summer Chinook hatchery-origin salmon with a clipped adipose fin (as evidenced by a healed scar). All salmon with an intact adipose fin (natural-origin) must be released back to the water. Therefore, incidental mortality impacts occur from catch and release of unclipped Snake River spring/summer Chinook salmon in fisheries targeting adipose-clipped hatchery Chinook salmon, and/or from the illegal retention of unclipped fish. It is generally assumed throughout the Columbia River Basin that the mortality rate resulting from the catch and release of salmon in fisheries is 10%. However, for Lookingglass Creek comanagers, with concurrence from NOAA fisheries, assume a slightly lower rate of 7.5% (ODFW and WDFW 2012). As stated in the FMEP, fisheries are adjusted or terminated when the total ESA take limit identified in Table 2 and 3 has been reached. Therefore, once fisheries are initiated regular monitoring is required to ensure consistency with co-manager agreements and FMEP requirements. The objective of this LSRCP project was to conduct statistical creel surveys to determine spring Chinook and steelhead ESA impact levels, harvest and release rates, and to inform decisions regarding fishery status in the Imnaha and Grande Ronde Basins in 2016. In this report, we describe creel surveys conducted and estimates of angler effort, catch, and harvest. In addition we compare these estimates in relation to estimates of natural and hatchery-origin returns to each population to assess consistency with prescribed impacts under FMEP guidelines.

Hatchery Chinook and steelhead smolts in the Snake River basin are produced at LSRCP hatcheries in Washington, Idaho and Oregon. Subsequent adult returns are meant to provide tribal and recreational (sport) fisheries and, in some cases, enhance natural spawner numbers. The Oregon Department of Fish and Wildlife (ODFW) initiated the Imnaha and Grande Ronde spring Chinook hatchery program in 1982 under the LSRCP. Subsequent program management has been coordinated between ODFW, the Confederated Tribes of the Umatilla Indian Reservation (CTUIR), and the Nez Perce Tribe (NPT). The Imnaha and Grande Ronde River hatchery programs are comprised of five components, each with smolt acclimation and adult collection facilities located on the Imnaha River, upper Grande Ronde River, Lookingglass and Catherine Creeks, and the Lostine River. The Lostine River program interacts with natural production within the broader Wallowa-Lostine population unit. Other hatchery program components are discrete to specific populations indicated. The Lookingglass Creek portion of the program focuses on reintroduction of spring Chinook to that stream and targets the release of 250,000 smolts. Each of the four remaining program components integrates natural-origin fish returning to each respective tributary into production. Smolt release goals, developed to meet LSRCP mitigation responsibilities; include 490,000 for the Imnaha, 250,000 for the Lostine and upper Grande Ronde rivers, and 150,000 for Catherine Creek. Fisheries that target returns to the Imnaha and Grande Ronde hatchery programs are guided by Fishery Management and Evaluation Plans (FMEP), approved by NOAA fisheries under limit 4 of the final 4(d) rule of the Endangered Species Act (ODFW 2011, ODFW and WDFW 2012). The objective of the FMEP is to provide recreational fishing opportunities and related benefits derived from harvest of Imnaha and Grande Ronde basin hatchery-origin spring Chinook salmon in Oregon and Washington in a manner that supports the continued survival and future recovery of natural-origin Chinook salmon. Each respective FMEP utilizes a management framework for harvest of adipose-clipped, hatchery-origin Snake River spring/summer Chinook salmon using abundance-based sliding scales to set annual fishery impacts. Fisheries are prescribed maximum impact rates for both direct and incidental mortality of natural-origin adult salmon in sport and tribal fisheries. Impacts are assessed for each population in relation to critical and minimum abundance thresholds (MAT) as described by the Interior Columbia Technical Recovery Team (ICTRT 2007). Population designations for the Imnaha and Grande Ronde Basins are listed in Table 1, and are based upon an analysis of Chinook salmon life history traits, distribution, abundance, and productivity, and geographical and ecological characteristics of the landscape within the Snake River Spring/Summer Chinook Salmon ESU (McElhany et al. 2000). The abundance-based harvest rate schedule for Imnaha and Grande Ronde Basin fisheries to be shared by all fishing entities in the basin is described in Table 2. Harvest is not considered when hatchery run size does not exceed the number of adults identified for broodstock and supplementation needs as described by sliding scale management plans set for each population’s hatchery program. Surplus is generally defined as the adult hatchery run projection less hatchery adults needed for broodstock. This approach limits sport harvest during years when wild fish runs are below MAT and hatchery fish runs are of similar size. In addition, near the lower end of the harvest rate scale, fisheries are not implemented until the allowable hatchery fish harvest exceeds 20 fish due to potential to over harvest within a single week. Fishery impacts to listed Snake River spring/summer Chinook salmon are assessed on a collective basis (i.e., the sum of recreational and tribal fisheries) by NOAA fisheries. However, the coordination of impact amongst states and tribes is a key component of executing conservation-based fisheries in the Imnaha and Grande Ronde Basins. Co-managers within each basin have developed, and implement annually, an impact sharing agreement that is described in Table 3. Within each fishery scenario, this agreement provides tribal fisheries more of the natural-origin impacts to reflect the non-selective nature of traditional fishing techniques. Recreational fisheries are provided a larger portion of the hatchery harvest such that all available impacts (hatchery and natural collectively) are shared equally (Table 3). Recreational fisheries administered by the states limit harvest (retention) of spring/summer Chinook hatchery-origin salmon with a clipped adipose fin (as evidenced by a healed scar). All salmon with an intact adipose fin (natural-origin) must be released back to the water. Therefore, incidental mortality impacts occur from catch and release of unclipped Snake River spring/summer Chinook salmon in fisheries targeting adipose-clipped hatchery Chinook salmon, and/or from the illegal retention of unclipped fish. It is generally assumed throughout the Columbia River Basin that the mortality rate resulting from the catch and release of salmon in fisheries is 10%. However, for Lookingglass Creek comanagers, with concurrence from NOAA fisheries, assume a slightly lower rate of 7.5% (ODFW and WDFW 2012). As stated in the FMEP, fisheries are adjusted or terminated when the total ESA take limit identified in Table 2 and 3 has been reached. Therefore, once fisheries are initiated regular monitoring is required to ensure consistency with co-manager agreements and FMEP requirements. The objective of this LSRCP project was to conduct statistical creel surveys to determine spring Chinook and steelhead ESA impact levels, harvest and release rates, and to inform decisions regarding fishery status in the Imnaha and Grande Ronde Basins in 2015. In this report, we describe creel surveys conducted and estimates of angler effort, catch, and harvest. In addition we compare these estimates in relation to estimates of natural and hatchery-origin returns to each population to assess consistency with prescribed impacts under FMEP guidelines.

This approach limits sport harvest during years when wild fish runs are below MAT and hatchery fish runs are of similar size. In addition, near the lower end of the harvest rate scale, fisheries are not implemented until allowable hatchery fish harvest exceeds 20 fish due to potential to over harvest within a single week. Fishery impacts to listed Snake River spring/summer Chinook salmon are assessed on a collective basis (i.e., the sum of recreational and tribal fisheries) by NOAA fisheries. However, the coordination of impact amongst states and tribes is a key component of executing conservation-based fisheries in the Imnaha and Grande Ronde Basins. Co-managers within each basin have developed, and implement annually, an impact sharing agreement that is described in Table 3. Within each fishery scenario, this agreement provides tribal fisheries more of the natural-origin impacts to reflect the non-selective nature of traditional fishing techniques. Recreational fisheries are provided more of the hatchery harvest such that all available impacts (hatchery and natural collectively) are shared equally (Table 3). Recreational fisheries administered by the states limit harvest (retention) of spring/summer Chinook hatchery-origin salmon with a clipped adipose fin (as evidenced by a healed scar). All salmon with an intact adipose fin (natural-origin) must be released back to the water. Therefore, incidental mortality impacts occur from catch and release of unclipped Snake River spring/summer Chinook salmon in fisheries targeting adipose-clipped hatchery Chinook salmon, and/or from the illegal retention of unclipped fish. It is generally assumed throughout the Columbia River Basin that the mortality rate resulting from the catch and release of salmon in fisheries is 10%. However, for Lookingglass Creek comanagers, with concurrence from NOAA fisheries, assume a slightly lower rate of 7.5% (ODFW and WDFW 2012). As stated in the FMEP, fisheries are adjusted or terminated when the total ESA take limit identified in Table 2 and 3 has been reached. Therefore, once fisheries are initiated regular monitoring is required to ensure consistency with co-manager agreements and FMEP requirements. The objective of this LSRCP project was to conduct statistical creel surveys determine spring Chinook and steelhead ESA impact levels, harvest and release rates, and to inform decisions regarding fishery status in the Imnaha and Grande Ronde Basins in 2013. In this report, we describe creel surveys conducted and estimates of angler effort, catch, and harvest. In addition we compare these estimates in relation to post-season preliminary estimates of natural and hatchery-origin returns to each population to assess consistency with prescribed impacts under FMEP guidelines.

These activities are coordinated under the Oregon Plan for Salmon and Watersheds and are part of a broader effort to monitor populations of salmonids in select Oregon coastal streams. Two objectives of this program are to estimate the abundance of returning adult salmonids and downstream-migrating juvenile salmonids, and estimate the marine and freshwater survival rates for coho salmon. This record provided catch summary reports from monitoring activities for the 2005-2006 run-year of returning adult fish and year 2006 out-migration of juvenile fish in the West Fork Smith River.

These surveys represent the fourth year of the US/Canada Pacific Salmon Treaty Monitoring Program implemented in 1986 by tribal, state and federal fishery agencies. The Pacific Salmon Treaty directs fishery management entities to conserve and rebuild chinook salmon stocks originating from the Columbia River Basin by appropriate ocean and in-river harvest controls. In order to monitor the success of the Pacific Salmon Treaty, annual spawner escapement of chinook salmon "indicator" stocks must be determined. The spring chinook salmon stocks of the John Day, Grande Ronde, and Imnaha River basins have been identified as potential indicator stocks for monitoring. These drainages were selected because of the unique wild salmon chinook stock in John Day River and wild stock component of spring chinook runs in the Grande Ronde and Imnaha Rivers. In addition, base line data have been established because ODFW has conducted spring chinook salmon spawning ground surveys in these basins since 1960. The comprehensive and multiple index surveys completed in 1989 were developed to collect information which could provide an estimate of spawner escapement and be comparable to historic redd survey data. In addition to spawning ground surveys, a new method was implemented to estimate spawning escapement. In 1989, snorkel and foot surveys were conducted in the Middle Fork John Day River to enumerate spring chinook salmon holding prior to spawning. The Middle Fork of John Day River was selected as the study site because 1) the holding and spawning area is only 30 miles long (the entire 30 miles could be sampled within one week) 2) the 30 mile section has good access by road and 3) the 30 mile section is generally narrow and shallow. Snorkeling and foot surveys were chosen as the method because 1) there are no weirs on the John Day River to count fish 2) snorkeling is a low-impact method and 3) other studies have shown snorkeling to be both time and cost effective with good success for estimating fish population size (Northcote and Wilkie (1963); Zubik and Frayley (1988)).

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

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

  Citation × Citation Citation Abstract Copy Title: Spring Chinook Salmon in the Willamette and Sandy Rivers, Progress Reports 2002, F-163-R-07 Abstract -- The Willamette and Sandy rivers support intense recreational fisheries for spring chinook salmon (Oncorhynchus tshawytscha). Fisheries in these basins rely primarily on annual hatchery releases of 5–8 million juveniles. Hatchery programs exist in the McKenzie, Middle Fork Willamette, North and South Santiam, Clackamas, and Sandy rivers mainly as mitigation for dams that blocked natural production areas. Some natural spawning occurs in most of the major basins and a few smaller tributaries upstream of Willamette Falls. The Oregon Fish and Wildlife Commission adopted the Wild Fish Management Policy to reduce adverse impacts of hatchery programs on wild native stocks (ODFW 1992a). The main goal of the policy is to protect the genetic diversity of these stocks recognizing that genetic resources are a major component, not only in sustaining wild stocks, but also in perpetuating 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 is being implemented to gather this information. A schematic of the study plan is shown in APPENDIX A. We conducted work in the main-stem Willamette River at Willamette Falls, and in the Middle Fork Willamette, McKenzie, North Santiam, South Santiam, Molalla, Clackamas, and Sandy rivers in 2002. Basin descriptions and background information on management and fish runs can be found in subbasin plans developed by the Oregon Department of Fish and Wildlife (ODFW 1988, ODFW 1992b, ODFW 1992c, and ODFW 1996).

  Citation × Citation Citation Abstract Copy Title: Preseason Report I, Stock Abundance Analysis for 1998, Ocean Salmon Fisheries Abstract -- This is the second report in an annual series of four reports prepared by the Salmon Technical Team (STT) of the Pacific Fishery Management Council (Council) to document and help guide salmon fishery management off the coasts of Washington, Oregon, and California. This report will be formally reviewed at the Council's March meeting. The third and fourth reports in this series will be developed at the close of the March and April Council meetings, respectively. They will analyze the impacts of the Council's proposed and final ocean salmon fishery management recommendations for 1998. This report provides 1998 salmon stock abundance projections and an analysis of the impacts of 1997 regulations, or regulatory procedures. The report focuses on chinook and coho stocks that have been important in determining Council fisheries in recent years. However, decisions on whether or not to propose Endangered Species Act listings for several chinook stocks ranging from central California to Puget Sound are anticipated in the near future. In the event that the National Marine Fisheries Service proposes new listings, information concerning the status of these stocks may significantly affect Council deliberations on the final salmon fishing seasons. Chapter I provides a summary of the 1998 stock abundance projections. Chapters II and Ill provide detailed stock-by-stock analyses of abundance and a description of prediction methodology and accuracy of past abundance predictions for chinook and coho salmon, respectively. Chapter IV summarizes abundance information for pink salmon. Four appendices provide supplementary information as follows: Appendix A provides a summary of Council stock management goals; Appendix 8 contains pertinent data for Oregon production index (OPI) area coho; Appendix C provides historical salmon catch data for the Cape Flattery and Strait of Juan de Fuca areas; and Appendix D contains the Council's current harvest allocation schedules. Summaries of preseason and postseason abundance estimates are included in: • Table 11-2 for Central Valley Index fall chinqok since 1985; • Table 11-4 for Klamath River fall chinook since 1985; • Table 11-8 for selected Columbia River fall chinook stocks since 1984; • Table 11-9 for Puget Sound summer/fall chinook stocks since 1993; • Table 111-1 for OPI area produced coho stocks since 1992 and • Table 111-3 for selected naturally spawning Puget Sound and Washington coastal coho stocks since 1984. Differences between preseason and postseason estimates are caused by a number of factors, including: (1) inaccuracies in abundance forecasts for these and other stocks which are exploited by mixed stock fisheries, (2) deviations of actual catches and fishery patterns from preseason expectations, (3) anomalies in stock distribution and migration patterns, and (4) for the Puget Sound coho stocks, differences in assessment methodologies (postseason estimates are based on run reconstruction assumptions which differ substantially from those represented in the Fishery Regulatory Assessment Model). The STT has not been able to complete a proper evaluation of abundance estimates which would take all these factors into account.

These estimates could be allocated to either hatchery or wild origin fish and it was possible to construct the riverine harvest rates for each year. It is estimated that for large size Hatchery origin fish (>55cm), the run has varied from a low of 475 in 1981 to 10,821 in 2001. For wild reared Chinook the run has varied from a low of 1,166 in 1991 to 3,456 in 1999. Estimates of small sized Chinook (<55cm) are made but are believed t~ be less reliable than for large fish. This group of fish has been proposed as an Exploitation Rate Indicator Stock for use in the Coast Model as a representative of the harvest impact of ocean fisheries on wild Chinook populations from the Umpqua and Mid-South Gene Conservation (MOC) Groups composed of the Umpqua, Coos, Coquille, Sixes Rivers and Floras creek. To prepare this stock for this role it was necessary to integrate the Port Orford Terminal Ocean fishery into the Elk River as none of the other populations are subjected to terminal fisheries. Using the annual estimated riverine harvest rates the recovery of Elk River ERI-stock Chinook in the Port Orford fishery beginning in mid-October until the end of the year were simulated as return to river and apportioned to catch or escapement. This information will now be available to the Chinook Technical Committee of the Pacific Salmon Commission to include the MOC group in the annual exploitation rate analysis. Additionally, this information can be used in the FRAM model for domestic ocean fishery management, and by local area managers for operational planning and fishery regulations in-river.

  Citation × Citation Citation Abstract Copy Title: Willamette Biological Opinion Hatchery Research 2013 Annual Report Abstract -- In the Willamette Basin upstream of Willamette Falls (Figure 1), there are four distinct spring Chinook salmon hatchery programs (North Santiam [Stock 21], South Santiam [Stock 24], McKenzie [Stock 23], and Middle Fork Willamette [Stock 22]) that are managed for integrated harvest augmentation as part of the Willamette Valley Hatchery Mitigation Program. 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 and other lower Columbia basins. The hatchery program currently includes annual smolt releases into the North Santiam, South Santiam, McKenzie, and Middle Fork Willamette rivers. Lack of access to historical habitat and degradation of remaining habitat below the dams, especially in the North and South Santiam (the “core” populations) are the key limiting factors shared between winter steelhead and spring Chinook salmon. In addition, summer steelhead are not native to the Willamette Basin upstream of Willamette Falls and a third, unique, limiting factor is the potential for competition, predation and genetic introgression from out-of-ESU hatchery fish interacting with and spawning in the wild with the native winter-run(Johnson et al. 2013). Summer steelhead were first introduced to the South Santiam River as mitigation for lost winter steelhead production in areas inundated by Foster and Green Peter reservoirs. The scope of work actually directed towards risks posed by summer steelhead is much smaller than that directed towards issues faced by spring Chinook salmon. The Willamette Project Biological Opinion (BiOP; NMFS 2008) required the USACE to collect information to describe the nature and extent of these potential effects but beyond relatively small-scale studies often integrated into much larger studies involving spring Chinook salmon, more focused work on steelhead will only follow commitment of significantly more effort and funds. 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.

  Citation × Citation Citation Abstract Copy Title: Imnaha River Basin Master Plan for Angler Access and Associated Recreational Uses 1996 Abstract -- The Imnaha River is a main tributary to the Snake River and drains a large portion of northeastern Oregon. The river system is 80 miles long and headwaters in the most southerly corner of Wallowa County, where tall pines are carpeted beneath with lush grass and a few smaller lodgepole. This is a very beautiful area and one that is not easily forgotten if it is once visited. The river runs cold and clear in this upper area and harbors rainbow and Dolly Varden trout. Downstream near the mouth of Gumboot Creek the river enters the canyon. The canyon walls remind one of the Snake River Canyon with its high bluffs and rimrocks. The fishery is a little more diversified in this area. In addition to a summer trout fishery, steelhead and salmon are taken in spring and early summer. At the present time salmon and steelhead angling pressure is concentrated below Horse Creek, but it is anticipated that this pressure will shift upstream when High Mountain Sheep Reservoir is filled. The system has been broken into four areas, each with their individual characteristics. The following sections describe these areas more fully and each access site is described in detail.

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

In recent years the Grande Ronde River was open to spring chinook angling however, due to limited harvest allotments, managers declined to open this fishery in 2016. Daily bag limits for all fisheries were two adipose fin-clipped chinook adults and five adipose fin-clipped jacks per day, with two daily limits in possession. Anglers were required to cease angling if they had retained a daily limit of marked adults.

  Citation × Citation Citation Abstract Copy Title: Grande Ronde Basin Spring Chinook Salmon Captive Broodstock Program 1995-2002 project status report Abstract -- The Grande Ronde Basin once supported large runs of chinook salmon Oncorhynchus tshawytscha and estimated peak escapements in excess of 10,000 occurred as recently as the late 1950’s (U.S. Army Corps of Engineers 1975). 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.
