Published by U.S. Fish and Wildlife Service | Department of the Interior | Metadata Last Checked: January 25, 2026 | Last Modified: 2025-04-03T00:00:00Z
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.
