  Citation × Citation Citation Abstract Copy Title: Grande Ronde River Basin Master Plan for Angler Access and Associated Recreational Uses 1966 Abstract -- The Grande Ronde Basin is quite a large basin that drains most of the northeastern corner of our State. The system has five tributary rivers. Two are accessible by trail only, the Wenaha near the Washington state line and the Minam that flows northward between La Grande and Enterprise. Catherine Creek drains the upper eastern part of the Grande Ronde Valley; the Wallowa and Lostine Rivers flow out of the Wallowa Valley. The Grande Ronde system supports a good fishery for salmon and steelhead. These fish migrate up the Columbia and Snake Rivers and travel approximately 650 river miles before they reach the spawning areas in the upper reaches of the basin. The Lower Grande Ronde enjoys a fall steelhead fishery; the upper tributaries have spring salmon and in some instances spring steelhead. In the peak of the season angling pressure is heavy and success is good. This report details a plan that we hope can be followed to solve the access problems of the Grande Ronde Basin.

The Upper Grande Ronde River (UGRR) and Joseph Creek watersheds support two of the four Major Population Groups (MPG) in the Grande Ronde River basin. These populations are segregated based on topographic, genetic, and behavioral evidence of interactions. Historically, the Grande Ronde River was one of the more significant anadromous fish producing rivers in the Columbia River Basin. Despite recovery efforts, these populations remain depressed relative to historic levels. The goal of this project is to annually evaluate summer steelhead population abundance for the UGRR, and recently Joseph Creek, by conducting surveys of redds and spawning activity. These surveys provide the data needed to estimate adult steelhead escapement, improve our understanding of habitat utilization, and contribute to productivity and survival estimates for these populations.

  Citation × Citation Citation Abstract Copy Title: 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. Lower Snake River Compensation Plan (LSRCP) ODFW- Eastern Oregon Fish Research (EOFR) 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).

The Upper Grande Ronde River (UGRR) and Joseph Creek basins support two of the four populations in the Grande Ronde Major Population Group (MPG). These populations are segregated based on topographic, genetic, and behavioral evidence of interactions. Historically, the Grande Ronde River was one of the more significant anadromous fish producing rivers in the Columbia River basin. Despite recovery efforts, these populations remain depressed relative to historic levels. The goal of this project is to annually evaluate summer steelhead population abundance for the UGRR, and recently Joseph Creek, by conducting surveys of redds and spawning activity. These surveys provide those data needed to estimate adult steelhead escapement, improve our understanding of habitat utilization, and contribute to productivity and survival estimates for these populations.

This closure was prompted by declining adult returns, as indicated by adult counts at Ice Harbor Dam on the Snake River (USACOE 1996), and low steelhead redd counts on index streams in the Grande Ronde and Imnaha river basins (Oregon Department of Fish and Wildlife District Annual Reports 1949-1974). The Lower Snake River Compensation Plan (LSRCP), initiated by Congress in 1976, was developed to compensate for losses of anadromous salmonids in the Snake River basin from construction of the four lower Snake River dams built between 1962 and 1976. Thus, the focus of the LSRCP is the Snake River above Lower Granite Dam (Rkm 173), the uppermost of these four dams. One of the primary objectives of the LSRCP in Oregon is to restore historic recreational and tribal fisheries for summer steelhead in the Grande Ronde and Imnaha river basins (Carmichael 1989). Approximately 1.68 million steelhead smolts were targeted for release in Oregon each year during April and May in the Grande Ronde and Imnaha river basins between 1984 and 1999. In 2000, we reduced releases to approximately 1.2 million smolts in response to the National Marine Fisheries Service’s recommendation to help reduce straying of Wallowa hatchery stock steelhead, primarily into the Deschutes River (midColumbia tributary). In 2007, we further reduced smolt releases to approximately 1.065 million, partly due to an increased release size from five to four fish per pound (fpp) for Wallowa stock which increased smolt-to-adult survival, and a reduction of Imnaha stock Big Sheep direct stream releases. In 2009, smolt releases were reduced again to approximately 1.015 million, due to reductions in releases of Imnaha stock into Big Sheep Creek. These fish provide hatchery adult returns that contribute to recreational fisheries and may supplement natural spawning populations in northeast Oregon. Consumptive recreational fisheries for summer steelhead re-opened in 1986, in part as a result of increases in hatchery adult returns.

Thus, the focus of the LSRCP is the Snake River above Lower Granite Dam (Rkm 173), the uppermost of these four dams. One of the primary objectives of the LSRCP in Oregon is to restore historic recreational and tribal fisheries for summer steelhead in the Grande Ronde and Imnaha river basins (Carmichael 1989). Approximately 1.68 million steelhead smolts were targeted for release in Oregon each year during April and May in the Grande Ronde and Imnaha river basins between 1984 and 1999. In 2000, we reduced releases to approximately 1.2 million smolts in response to the National Marine Fisheries Service’s recommendation to help reduce straying of Wallowa Hatchery stock steelhead, primarily into the Deschutes River (mid-Columbia tributary). In 2007, we further reduced smolt releases to approximately 1.065 million, partly due to an increased release size from five to four fish per pound (fpp) for Wallowa stock, which increased smolt-to-adult survival (Clarke et al. 2014), and due to a reduction of Imnaha stock Big Sheep direct stream releases. In 2009, smolt releases were reduced again to approximately 1.015 million, due to reductions in releases of Imnaha stock into Big Sheep Creek. Released smolts provide hatchery adult returns that contribute to recreational fisheries and may supplement natural spawning populations in northeast Oregon. Consumptive recreational fisheries for summer steelhead re-opened in 1986, in part as a result of increases in hatchery adult returns. Lower Snake River Compensation Plan (LSRCP) ODFW- Eastern Oregon Fish Research (EOFR) Title: Summer Steelhead Creel Surveys on the Grande Ronde, Wallowa, and Imnaha Rivers for the 2014-15 Run Year Abstract -- Summer steelhead (Oncorhynchus mykiss) fisheries in the Grande Ronde and Imnaha river basins were closed in 1974.

  Citation × Citation Citation Abstract Copy Title: Summer Steelhead Creel Surveys on the Grande Ronde, Wallowa, and Imnaha Rivers for the 2000-01 Run Year Abstract -- Summer steelhead (Oncorhynchus mykiss) fisheries in the Grande Ronde and Imnaha basins were closed in 1974. This closure was prompted by declining adult returns, as indicated by adult counts at Ice Harbor Dam on the Snake River (U.S. Army Corps of Engineers 1996) and low steelhead redd counts on index streams in the Grande Ronde and Imnaha basins (Oregon Department of Fish and Wildlife District Annual Reports 1949-1974). The Lower Snake River Compensation Plan (LSRCP), initiated by Congress in 1976, was developed to compensate for losses of anadromous salmonids in the Snake River basin from construction of the four lower Snake River Dams built between 1962 and 1976. Thus, the focus of the LSRCP is above Lower Granite Dam (Rkm 173), the uppermost of the four lowest dams on the Snake River. One of the primary objectives of the LSRCP in Oregon is to restore historic recreational and tribal fisheries for summer steelhead in the Grande Ronde and Imnaha basins (Carmichael 1989). Approximately 1.68 million steelhead smolts have been released in Oregon each year during April and May in the Grande Ronde and Imnaha basins until 2000, when we reduced releases to approximately 1.2 million smolts. This reduction was implemented due to a National Oceanic and Atmospheric Administration (NOAA) Fisheries’ recommendation to help reduce straying of Wallowa hatchery stock steelhead, primarily into the Deschutes River (mid-Columbia tributary). These fish provide hatchery adult returns that contribute to recreational fisheries and may supplement natural spawning populations in northeast Oregon. Consumptive recreational fisheries for summer steelhead re-opened in 1986, in part as a result of increases in hatchery adult returns.

These fish provide hatchery adult returns that contribute to recreational fisheries and may supplement natural spawning populations in northeast Oregon. Consumptive recreational fisheries for summer steelhead re-opened in 1986, in part as a result of increases in hatchery adult returns.

This closure was prompted by declining adult returns, as indicated by adult counts at Ice Harbor Dam on the Snake River (USACOE 1996), and low steelhead redd counts on index streams in the Grande Ronde and Imnaha river basins (Oregon Department of Fish and Wildlife District Annual Reports 1949-1974). The Lower Snake River Compensation Plan (LSRCP), initiated by Congress in 1976, was developed to compensate for losses of anadromous salmonids in the Snake River basin from construction of the four lower Snake River dams built between 1962 and 1976. Thus, the focus of the LSRCP is the Snake River above Lower Granite Dam (Rkm 173), the uppermost of these four dams. One of the primary objectives of the LSRCP in Oregon is to restore historic recreational and tribal fisheries for summer steelhead in the Grande Ronde and Imnaha river basins (Carmichael 1989). Approximately 1.68 million steelhead smolts were targeted for release in Oregon each year during April and May in the Grande Ronde and Imnaha river basins between 1984 and 1999. In 2000, we reduced releases to approximately 1.2 million smolts in response to the National Marine Fisheries Service’s recommendation to help reduce straying of Wallowa hatchery stock steelhead, primarily into the Deschutes River (midColumbia tributary). In 2006, we further reduced smolt releases to approximately 1.065 million, partly due to an increased release size from five to four fish per pound (fpp) for Wallowa stock which increased smolt-to-adult survival, and a reduction of Imnaha stock Big Sheep direct stream releases. These fish provide hatchery adult returns that contribute to recreational fisheries and may supplement natural spawning populations in northeast Oregon. Consumptive recreational fisheries for summer steelhead re-opened in 1986, in part as a result of increases in hatchery adult returns.

Also summarized are the associated adult broodstock monitoring data collected in the Grande Ronde Basin by our co-managers, Nez Perce Tribe (NPT) and Confederated Tribes of the Umatilla Indian Reservation (CTUIR). 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. Our co-managers, 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 reports prepared by each co-management agency. Overall, these data are used to modify culture practices as needed in order to optimize the egg-to-smolt survival, smolt quality, smolt-to-adult survival rate, and to track spawning in nature by hatchery-reared adults. This report provides information on rearing and release operations for the 2006 brood year of juvenile Chinook salmon smolts, the collection of eggs for the 2008 brood year, Chinook spawning in nature, numbers and characteristics of adult Chinook salmon in the 2008 return year, recruit summary and age composition of the 2003 brood year, and bacterial kidney disease (BKD) monitoring.

This closure was prompted by declining adult returns, as indicated by adult counts at Ice Harbor Dam on the Snake River (U.S. Army Corps of Engineers 1996) and low steelhead redd counts on index streams in the Grande Ronde and Imnaha basins (Oregon Department of Fish and Wildlife District Annual Reports 1949-1974). The Lower Snake River Compensation Plan (LSRCP), initiated by Congress in 1976, was developed to compensate for losses of anadromous salmonids in the Snake River basin from construction of the four lower Snake River Dams built between 1962 and 1976. Thus, the focus of the LSRCP is above Lower Granite Dam (Rkm 173), the uppermost of the four lowest dams on the Snake River. One of the primary objectives of the LSRCP in Oregon is to restore historic recreational and tribal fisheries for summer steelhead in the Grande Ronde and Imnaha basins (Carmichael 1989). Approximately 1.68 million steelhead smolts have been released in Oregon each year during April and May in the Grande Ronde and Imnaha basins until 2000, when we reduced releases to approximately 1.2 million smolts. This reduction was implemented due to a National Oceanic and Atmospheric Administration (NOAA) Fisheries’ recommendation to help reduce straying of Wallowa hatchery stock steelhead, primarily into the Deschutes River (mid-Columbia tributary). These fish provide hatchery adult returns that contribute to recreational fisheries and may supplement natural spawning populations in northeast Oregon. Consumptive recreational fisheries for summer steelhead re-opened in 1986, in part as a result of increases in hatchery adult returns.

Also summarized are the associated adult 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 reports prepared by each co-management agency). Overall, these data are used to modify culture practices, as needed, in order to optimize egg-to-smolt survival rate, smolt quality, and smolt-to-adult survival rate, and track spawning in nature by hatchery-reared adults. This report provides information on rearing and release operations for the 2009 brood year of juvenile Chinook salmon smolts, the collection of eggs for the 2011 brood year, numbers and characteristics of adult Chinook salmon in the 2011 return year, the 2011 spawning year at Lookingglass Fish Hatchery and in nature, recruit summary and age composition of the 2006 brood year, and bacterial kidney disease (BKD) monitoring.

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.

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

  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.

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 2014. 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.

  Citation × Citation Citation Abstract Copy Title: Lower Snake River Compensation Plan; Oregon Spring Chinook Salmon Harvest Monitoring - 2013 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 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 initiated the Imnaha and Grande Ronde spring Chinook hatchery program in 1982 under the LSRCP. Subsequent program management has been coordinated between ODFW, Confederated Tribes of the Umatilla Indian Reservation (CTUIR) and 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 originating from the Catherine Creek population. 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 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 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).

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.

  Citation × Citation Citation Abstract Copy Title: Lower Snake River Compensation Plan; Oregon Summer Steelhead Evaluation Studies - 2012 Annual Progress Report Abstract -- The objectives of this report are to document fish culture practices, describe adult returns, and assess progress toward meeting LSRCP goals for Grande Ronde and Imnaha steelhead (Oncorhynchus mykiss). We report on juvenile steelhead rearing and release activities for the 2011 brood year (BY) released in 2012. Included are collection, spawning, and adult characteristics for the 2012 returns, returns from experimental releases, supplementation in Little Sheep Creek, and success toward achieving compensation goals. The Grande Ronde and Imnaha river steelhead hatchery programs were initiated in 1976 and 1982 in response to the rapid decline in Snake River steelhead abundance. Annual adult mitigation, brood year specific smolt-to-adult return and total smolt-to-adult survival rates, and annual smolt production goals were established to compensate for the estimated annual loss of 48% of adult production. Adaptive management has resulted in current interim smolt production goals of 800,000 (Wallowa stock released into the Grande Ronde) and 215,000 (Imnaha stock) smolts; less than the original goals of 1,350,000 and 330,000 smolts. Based on original smolt production goals it was assumed that 27,552 Wallowa stock and 6,000 Imnaha stock adults would be produced annually. Furthermore, 66.7% of these fish were expected to be harvested below the compensation area, defined as the watershed above Lower Granite Dam, resulting in compensation area adult return goals of 9,184 (Wallowa stock) and 2,000 (Imnaha stock). In general, the data in this report were derived from hatchery inventories and standard databases (e.g., Pacific States Marine Fisheries Commission Regional Mark Information System (RMIS), ODFW mark recovery) or through standard measuring techniques. As such, specific protocols are usually not described. In cases where expansions of data or unique methodologies were used, protocols are described in more detail. Additional descriptions of protocols can be found in our work statements (Carmichael et al. 2009, Carmichael et al. 2010). Coded-wire tag (CWT) data collected from 2012 adult returns were used to evaluate smolt-to-adult survival rates in experimental rearing and release groups. In 2012, experimental treatments from which fish returned included unmarked releases, off-station direct-stream releases, and progeny from early returning (fall-collected) broodstock release strategies. In 2012, smolts were released at Wallowa Hatchery that were second generation progeny of early returning (fall-collected) broodstock for an experimental comparison with progeny of standard production broodstock. Methods for the fall broodstock experiment are described in Warren et al. (2011). Analysis of specific survival studies will be completed and published in separate reports once all brood years have returned and CWT data are complete for each experiment. In addition, much of the data that we discuss in this report will be used in separate and specific evaluations of ongoing supplementation programs for steelhead in the Imnaha River basin.

In general, the data in this report were derived from hatchery inventories and standard databases (e.g., Pacific States Marine Fisheries Commission Regional Mark Information System (RMIS), ODFW mark recovery) or through standard measuring techniques. As such, specific protocols are usually not described. In cases where expansions of data or unique methodologies were used, protocols are described in more detail. Additional descriptions of protocols can be found in our work statements (Carmichael et al. 2012, Carmichael et al. 2013). Coded-wire tag (CWT) data collected from 2014 adult returns were used to evaluate smolt-to-adult survival rates in experimental rearing and release groups. In 2014, the only experimental treatments from which fish returned were second generation progeny from early returning (fall-collected) broodstock. In 2014, smolts were released at Wallowa Hatchery that were third generation progeny of early returning (fall-collected) broodstock for an experimental comparison with progeny of standard production broodstock. Methods for the fall broodstock experiment are described in Warren et al. (2011a). Analysis of specific survival studies will be completed and published in separate reports once all brood years have returned and CWT data are complete for each experiment. In addition, much of the data that we discuss in this report will be used in separate and specific evaluations of ongoing supplementation programs for steelhead in the Imnaha River basin. Lower Snake River Compensation Plan (LSRCP) ODFW- Eastern Oregon Fish Research (EOFR) Title: Lower Snake River Compensation Plan; Oregon Summer Steelhead Evaluation Studies - 2014 Annual Progress Report Abstract -- The objectives of this report are to document fish culture practices, describe adult returns, and assess progress toward meeting LSRCP goals for Grande Ronde and Imnaha steelhead (Oncorhynchus mykiss). We report on juvenile steelhead rearing and release activities for the 2013 brood year (BY) released in 2014. Included are collection, spawning, and adult characteristics for the 2014 returns, returns from experimental releases, supplementation in Little Sheep Creek, and success toward achieving compensation goals. The Grande Ronde and Imnaha river steelhead hatchery programs were initiated in 1976 and 1982 in response to the rapid decline in Snake River steelhead abundance. Annual adult mitigation, brood year specific smolt-to-adult return and total smolt-to-adult survival rates, and annual smolt production goals were established to compensate for the estimated annual loss of 48% of adult production. Adaptive management has resulted in current interim smolt production goals of 800,000 (ODFW Wallowa stock released into the Grande Ronde) and 215,000 (Imnaha stock) smolts; less than the original goals of 1,350,000 and 330,000 smolts. Based on original smolt production goals it was assumed that 27,552 Wallowa stock and 6,000 Imnaha stock adults would be produced annually.

  Citation × Citation Citation Abstract Copy Title: Phillips Creek Watershed Assessment Abstract -- Watershed Assessments for the Grande Ronde River Subwatersheds are being prepared for the Grande Ronde Model Watershed Program. This Watershed Assessment addresses the Phillips Creek Watershed located near Elgin, Oregon. Phillips Creek is a relatively small watershed (4th order HUC – Hydrologic Unit Classification) containing about 33 square miles or slightly over 24,000 acres. Phillips Creek empties into the Grande Ronde River in Elgin. It is an intermittent stream in some reaches, but water flows year around in other reaches. In this Assessment the main emphasis is on the nonfederal lands. The USDA Forest Service – Umatilla National Forest recently completed a watershed assessment on the National Forest area that includes Phillips, Cabin, Gordon and Dry Creeks. For more complete information on watershed condition on federal lands, please refer to the Umatilla National Forest’s Phillips-Gordon Ecosystem Analysis (PGEA). This assessment will describe the Phillips Creek watershed and help to identify the stream processes and features that are working well, and those that are not. Information that is already available from state and federal agencies as well as from private sources (including people that live in the area) will be used. Several public meetings were held to obtain information and insights from people that live in the area. The assessment will identify human’s positive and negative influences to the immediate stream environment. The assessment should provide enough information to develop project plans and monitoring plans that will help to protect and improve water quality and fish habitat in Phillips Creek and its tributaries. This assessment includes a description of Phillips Creek Watershed, historical conditions assessment, channel habitat type classification, hydrology and water use, riparian assessment, wetlands assessment, sediment sources assessment, channel modification assessment, water quality assessment, water rights assessment, fish and fish habitat assessment, upland conditions assessment – Forest, upland conditions assessment – Range, developed area assessment, noxious weeds assessment, and a watershed condition evaluation.

  Citation × Citation Citation Abstract Copy Title: Monitoring and Evaluation Plan for Northern Oregon Hatchery Imnaha and Grande Ronde Subbasin Spring Chinook Salmon Abstract -- This document describes a monitoring and evaluation (M&E) plan that will allow co-managers to determine whether they are successful in meeting management goals and objectives. It is, therefore, intended to guide evaluation of the NEOH program, give empirical evidence of effects and fill knowledge gaps regarding supplementation and its uncertainty as an enhancement tool. Program success will be gauged primarily by changes in abundance, productivity, diversity and distribution of the supplemented populations, the performance of the hatchery fish relative to their natural counterparts, impacts to non-target populations, and the restoration of tribal and recreational fisheries. Prior to the detailed methodology sections, the plan provides a brief status review of the Imnaha and Grand Ronde Chinook salmon populations, an overview of the NEOH production program and a description of our approach to monitoring and evaluation. Researchers from northeast Oregon have relied on numerous contemporary documents to develop a plan that (1) coordinates an array of monitoring and evaluation activities, (2) fits within a regional framework, and (3) results in information with broad applicability. The plan also drew from federal, state, tribal, academic and independent sources for monitoring and evaluation recommendations and statistical council.

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

  Citation × Citation Citation Abstract Copy Title: Development of Methods to Estimate Spawning Escapement of Spring Chinook in the John Day, Grande Ronde and Imnaha River Basins of Northeast Oregon; 1989 Summary Report Abstract -- The Confederated Tribes of the umatilla Indian Reservation (CTUIR), in conjunction with the Oregon Department of Fish and Wildlife (ODFW) , and Nez Perce Tribe (NPT), conducted comprehensive spawning ground surveys for spring chinook salmon (Oncorhynchus tshawytscha) in the John Day, Grande Ronde, and Imnaha River basins in 1989. 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)).

  Citation × Citation Citation Abstract Copy Title: Lower Snake River Compensation Plan; Oregon Evaluation Studies - 1995 and 1996 Annual Progress Report Abstract -- This report summarizes fish culture monitoring data for Lower Snake River Compensation Plan (LSRCP) facilities for each species. These data should serve as the basis for the analysis of trends in culture performance. Generally speaking, the data in this report were derived from hatchery inventories and standard databases (i.e., PSMFC, Coded-wire tag) or through standard measuring techniques. As such, specific protocols are usually not described. In cases where expansions of data or unique methodologies were used, protocols are described in more detail. Additional descriptions of protocols can be found in the 1995 and 1996 work statements (Carmichael 1995, 1996). Coded-wire tag (CWT) data that were collected from 1995-1996 adult returns is used to evaluate smolt-to-adult survival rates in experimental rearing and release groups. In 1995-1996, experimental treatments from which fish returned included acclimated vs. direct stream for steelhead and size-at-release for both steelhead and Chinook. In 1995-1996, experimental treatments for which fish were released included size-at-release, exercise, acclimation, and low density treatments for Chinook, acclimated vs. direct stream for both steelhead and Chinook, and forced vs. volitional release for steelhead. Analysis of specific survival studies will be completed once all brood years have returned and CWT data are complete for a given experiment. In addition, much of the data that we discuss in this report will be used in separate and specific evaluations of ongoing supplementation programs for both steelhead and Chinook in the Imnaha River basin.

These ongoing monitoring programs provide technical, logistical, and biological information to managers charged with maintaining viable salmon and steelhead populations and associated fisheries in Northeast Oregon. This report summarizes fish culture monitoring data for LSRCP facilities for summer steelhead. These data serve as the basis for the analysis of trends in culture performance.

In 1997-1998, experimental treatments from which fish returned included acclimated vs. direct stream and forced vs. volitional release strategies. In 1997-1998, experimental treatments for which fish were released included density treatments, forced vs. volitional release, rearing site, and growth treatments. Analysis of specific survival studies will be completed once all brood years have returned and CWT data are complete for a given experiment. In addition, much of the data that we discuss in this report will be used in separate and specific evaluations of ongoing supplementation programs for steelhead in the Imnaha River basin.

We report on juvenile steelhead rearing and release activities for the 2000 and 2001 brood years (BY) released in 2001 and 2002, respectively. Included are collection, spawning, and adult characteristics for the 2001 and 2002 returns, returns from experimental releases, supplementation in Little Sheep Creek, and success toward achieving compensation goals. Generally speaking, the data in this report were derived from hatchery inventories and standard databases (i.e., PSMFC RMIS, ODFW coded-wire tag) or through standard measuring techniques. As such, specific protocols are usually not described. In cases where expansions of data or unique methodologies were used, protocols are described in more detail. Additional descriptions of protocols can be found in the 2001 and 2002 work statements (Carmichael et al. 2001, 2002). Coded-wire tag (CWT) data that were collected from 2001-2002 adult returns were used to evaluate smolt-to-adult survival rates in experimental rearing and release groups. In 2001-2002, experimental treatments from which fish returned included forced vs. volitional release, growth and density treatments, and a pre-smolt release strategy. In 2001-2002, experimental treatments for which fish were released included forced vs. volitional, and acclimated vs. direct stream release strategies. We also released non-clipped, blank-wire tagged and visual implant elastomer (VIE) marked steelhead. Analysis of specific survival studies will be completed once all brood years have returned and CWT data are complete for a given experiment, and will be published in special reports. In addition, much of the data that we discuss in this report will be used in separate and specific evaluations of ongoing supplementation programs for steelhead in the Imnaha River Basin.
