PIT Tag Survival and Travel Time Analysis
Survival and travel time analysis and plots for Columbia Basin PIT-tagged hatchery and wild salmon. Includes:
- Cormack Jolly-Seber survival estimates for Release to Lower Granite, McNary, and John Day as well as single reach estimates (e.g., Lower Granite to Little Goose) and combined reach estimates (e.g., Lower Granite to McNary);
- Travel Time estimates for Release to Lower Granite, McNary, and John Day as well as Lower Granite to McNary where appropriate; and
- Detection Probability estimates at various project locations on the Columbia and Snake rivers.
For all analysis, a reach is defined from the release location or the tailrace of the upper project to the tailrace of the lower project.
Analysis ended in 2009. For current analysis results, please see Columbia Basin Annual Trends.
