The Fish Passage Center publishes a Weekly Report each Friday from mid-March
through the first of September, and bi-weekly thereafter through November. These reports
summarize the current biological and physical conditions, and river operations affecting
the migrations of juvenile and adult salmon and steelhead in the Columbia and Snake river
Most of the data summarized in the weekly report are updated on a daily
basis. The files updated daily are the Daily Average Flow and Spill,
Total Dissolved Gas, Catch Report, Passage Indices,
Transportation Summary Reports and Adult Passage. Gas
Bubble Trauma Monitoring results are done twice a week; cumulative
adult counts and hatchery releases are done once a week.
