Query Notes
- ESU (Evolutionarily Significant Unit) and DPS (Distinct Population Segment) Glossary, DART PIT Tag and ESU Metadata & Glossary
- Click on a reach travel time in the table to view a plot of the reach-specific daily mean travel time as it varies throughout the season. The date of the daily mean travel time is determined by and plotted on the reach entry date, i.e., the date of the last detection for each PIT-tagged fish at the first project in the reach. The plots include a 95% confidence interval for each reach entry date on which more than one fish started traversing the reach.
- The Snake River Fall Chinook ESU includes naturally spawned fall-run Chinook salmon originating from the mainstem Snake River below Hells Canyon Dam and from the Tucannon River, Grande Ronde River, Imnaha River, Salmon River, and Clearwater River subbasins. Also, fall-run Chinook salmon from four artificial propagation programs:
Lyons Ferry Hatchery Program,
Fall Chinook Acclimation Ponds Program,
Nez Perce Tribal Hatchery Program, and
Oxbow Hatchery Program.
Definition implemented by Columbia River DART: June 2007.
