DART Adult Passage Visual Counts Metadata & Glossary
The DART Columbia Basin Adult Passage "Quick Look" Summary presents current adult passage counts with the ten year averages at Bonneville, McNary, Ice Harbor, Lower Granite, Priest Rapids, and Wells dams. Updated daily.
Lamprey Counts: Historically, DART has only offered daytime counts (fish counting hours 1-16) which were identified as Lamprey but not specified as daytime counts. As of 2025-11-14, where available, DART offers up to three mutually exclusive lamprey counts: daytime fishway ladder counts (hours 1-16), nighttime fishway ladder counts (hours 17-24), and LPS (24 hour count in Lamprey Passage Systems).
