We report on juvenile steelhead rearing and release activities for the 2004 brood year (BY) released in 2005. Included are collection, spawning, and adult characteristics for the 2005 returns, returns from experimental releases, supplementation in Little Sheep Creek, and success toward achieving compensation goals. 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 and Hoffnagle 2004, Carmichael et al. 2005c, Carmichael et al. 2005d). Coded-wire tag (CWT) data that were collected from 2005 adult returns were used to evaluate smolt-to-adult survival rates in experimental rearing and release groups. In 2005, experimental treatments from which fish returned included forced vs. volitional release, a pre-smolt release, non-clipped, blank-wire tagged release, and off-station direct-stream release strategies. In 2005, experimental fish were released to evaluate progeny from early returning (fall-collected) broodstock vs. production broodstock. We also released non-clipped, blank-wire tagged smolts, and two groups (marked and unmarked/untagged) of off-station direct stream release smolts, to compare to production releases. 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 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 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. Lower Snake River Compensation Plan (LSRCP) ODFW- Eastern Oregon Fish Research (EOFR) 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).

We report on juvenile steelhead rearing and release activities for the 2013 brood year (BY) released in 2014.
