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
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.
