NOAA Fisheries is a cooperator with the Washington Department of Fish and Wildlife and the Lummi, Nooksack, and Stillaguamish Tribes in a 10-year program to rebuild the South Fork Nooksack River spring Chinook and Stillaguamish River fall Chinook stocks through a captive broodstock program. Raw data on rearing density, loading density, water temperature, ration, and feed size may be available. Raw data on administration of therapeutic drugs may be available.

Federally-threatened ago-0 spring Chinook salmon (Oncorhynchus tshawytscha) were acoustic tagged and released near Lookout Point Reservoir to estimate passage and survival during an experimental reservoir drawdown operation that was designed to facilitate downstream passage through two reservoirs and dams. The experimental operation consisted of lowering the water surface elevation of Lookout Point Reservoir on the Middle Fork Willamette River from 823 ft in late August 2023 to 750 ft by early November 2023 and passing water through regulating outlets at Lookout Point Dam. This operation was intended to improve fish passage for juvenile Chinook salmon through Lookout Point Dam. During our study, acoustic-tagged juvenile Chinook salmon produced by Oregon State University's Wild Fish Surrogate Program were released weekly during late August to late October to determine how fish responded to the drawdown. Detection sites were in Lookout Point Reservoir and Dexter Reservoir on the Middle Fork Willamette River; and near the city of Eugene, Oregon, and near Willamette Falls on the Willamette River. Estimates of fish survival through the study area were calculated from the release and detection records and combined with time-varying covariates of Lookout Dam operations and water temperature in Lookout Point Reservoir and the Middle Fork Willamette River.

Critical habitat includes the stream channels within the designated stream reaches, and includes a lateral extent as defined by the ordinary high-water line (33 CFR 319.11). In areas where ordinary high-water line has not been defined, the lateral extent is defined by the bankfull elevation. Bankfull elevation is the level at which water begins to leave the channel and move into the floodplain and is reached at a discharge which generally has a recurrence interval of 1 to 2 years on the annual flood series. Critical habitat in lake areas is defined by the perimeter of the water body as displayed on standard 1:24,000 scale topographic maps or the elevation of ordinary high water, whichever is greater.See the final rule (70 FR 52630) for descriptions of areas excluded from this critical habitat designation. Military areas ineligible for designation (qualifying Integrated Natural Resource Management Plan) were not clipped out of the data. Excluded military areas (due to national security impacts), Habitat Conservation Plan (HCP) lands, and Indian lands were not clipped out of the data.

Juvenile Chinook salmon (age 0 and age 1), steelhead, and sockeye salmon were acoustic tagged and released at sites along the Yakima River in and below Yakima, WA 2018-2024. Detection sites varied across years but included arrays placed at diversion dams, canals, hydropower facilities, and other locations throughout the Yakima and Columbia rivers. Study design included paired fish releases above and below irrigation diversions to evaluate effects on fish movement and survival. Overall, the purpose of this study was to evaluate the effects of barriers and other structures on juvenile Chinook salmon and steelhead behavior and survival across variable hydrological conditions.

Tabular dataset containing age, sex, and length data for Chum, Chinook, and Sockeye salmon. Sex was determined externally using visual clues such as snout shape and size. Length was measured from fork to mid-eye with a measuring board to the closest 5 mm. Strata refers to the potion of the run the fish was sampled during. Strata data is based on the size of the population rather than date since the salmon run does not start on one specific date year by year. Scales were also taken and placed on a gum card for age assessment. One scale was taken for all sampled Chum salmon and three scales were taken for all sampled Chinook salmon.

The California Monitoring Plan (CMP) salmonid monitoring areas and associated population data are part of an ongoing effort to summarize existing and past salmonid monitoring efforts in the areas identified by Adams et al. 2011. These data are compiled and maintained by the California Department of Fish and Wildlife with the cooperation of monitoring practitioners. Updates and associated outreach are intended to occur on an annual basis. Data were created from several sources and existing datasets: some monitoring areas were accurately depicted using the USGS National Hydrography Dataset (NHD), other monitoring areas were approximated using the monitoring point location and the USGS StreamStats tool to depict the watershed area above that point. The areas are intended to represent the approximate extent of sampling within sub-basins, watershed areas, or regions. For example, the spatial extent of monitoring using a fixed count station is approximated by accounting for all anadromous fish habitat upstream of the sampling location. Therefore, the area is approximated by entering the monitoring location coordinates into the StreamStats tool. The resulting shapefile is then examined to ensure the watershed area did not include habitat above dams or barriers to migration. Areas were clipped when needed. The data user should recognize that errors may have occurred during production of this dataset, changes may have occurred to the external sources used post transfer, and for other possible reasons. The population metrics summarized in the associated tabular data may be regarded as spatially limited, temporally limited, and not considered a complete estimate for the population being described. The data user is advised to refer to the annual reports cited in the Source field from the tabular data for additional details regarding monitoring within the area spatially depicted.Abbreviation Definitions: SGS = Spawning Ground Survey, RM = River Mile, RST = Rotary Screw Trap, RKM

Hourly counts of all fish species observed at the Andreafsky Weir. Data are derived from weir video feed for available years 2015-2023. Counts were done hour by hour for 24 hours a day unless maintenance was required or conditions disrupted the video feed. NA delineates times in which the video feed was not active while 0 delineates that no fish were counted for that hour. All species have been standardized and counted every year since the implementation of the video feed.

During the period of 1987 to 1994, Robin J. LeBrasseur and N. Brent Hargreaves lead a juvenile salmon predation research project in Alberni Inlet and Barkley Sound BC. This dataset contains the research survey catch data and individual fish examinations data.
