Abundance and run timing of non-target species in the Andreafsky River at Yukon Delta National Wildlife Refuge, Alaska

공공데이터포털

Tabular dataset containing daily and cumulative counts of all fish species apart from Chum and Chinook salmon detected and recorded at the Andreafsky weir for the years 1994 through 2019, 2021, and 2023. Species included differed year by year depending on what was observed at the weir. Counts were done manually at the weir until the introduction of a video feed in 2007. NA refers to missing data whereas 0 refers to no observation made. Data was compiled by Randy Brown and Jeff Melagari for years 1994 through 2016. For 2017 on, data was taken from post season reports.

Fall Chinook Escapement - Klamath Basin Watershed

공공데이터포털

Adult salmonid data collected from various areas within the Klamath basin watershed. Various tributaries are monitored using video systems (Bogus Creek, Shasta River, Scott River), other areas are monitored using redd/carcass surveys, and Iron gate Hatchery adult returns. The main purpose of the data is to estimate escapement of fall Chinook slamon, although data on other species (steelhead, coho salmon) also collected. For more information on the various collection methods, please view the specific metadata document included with the data download. This data and metadata were submitted by California Department of Fish and Wildlife (CDFW) Staff though the Data Management Plan (DMP) framework with the id: DMP000381.

Riverscape snorkeling surveys of salmonid distribution and abundance before (2007, 2008) and after (2018, 2019) dam removal on the Elwha River, Washington

공공데이터포털

We used snorkel surveys in the Elwha River, conducted in consecutive years before (2007, 2008) and after (2018, 2019) dam removal to assess changes in fish distribution and density. In total, we counted 54,616 Chinook Salmon, Bull Trout, Steelhead, and trout (Rainbow Trout and Coastal Cutthroat Trout combined) in 22 common reaches spanning 65 river kilometers. The occupancy of juvenile Chinook Salmon, Coho Salmon, and trout was also assessed following dam removal.
