Escapement goal

No escapement goal applies to a dam count — goals are set for spawning escapement, and a dam tally is passage, not escapement. The yardstick on this page is the run's own history.

The 2016–2025 average final is 38,430.

About this count

How it is counted: Dam ladder count at Snake River mile 107.

Dam day counts are expanded estimates: counters watch the ladders 16 hours a day, 50 minutes of every hour, and the day count is that tally multiplied by 1.2. Fish passing at night, through the navigation lock or through turbines are not counted. The Corps reviews counts with video after the season and occasionally revises them.

Counts post daily in season; in-season figures are preliminary, and the Corps reviews the season after it closes — the figures here are the final published ones. Source: Fish Passage Center — Adult Data Query (U.S. Army Corps of Engineers counts).
