Juvenile Stranding Query

Query Notes

• CDFW Upper Sacramento River Basin Salmonid Monitoring, CalFish for more information, including annual reports.
• Stranding surveys are conducted by boat and by foot between Tehama Bridge (RM 229) and Keswick Dam (RM 302).
• Time: This category allows determination of flows at the site by using a relationship between flow from Keswick Dam and the distance downstream ("Relationship between Distance and Time and Flows for the Sacramento River Between Keswick Dam (RM 302) and Tehama Bridge (RM 229)." table in appendix of annual report)
• Waypoint Number: This is a number assigned to each potential stranding site using the GPS unit. The first digit corresponds to the site survey section number.
• Winter-run Number: This is the estimated number of winter-run sized salmon observed in the stranding site. Size cut-offs are determined by each specific date using a screw trap developed length cut off chart for the Upper Sacramento River ( example: Appendix B, Daily fork-length table from data by Frank Fisher, Sheila Greene California Department of Fish and Game. California Department of Water Resources ).
• Spring-run Number: This is same as winter-run above except for spring-run.
• Fall-run Number: This is same as winter-run above except for fall-run.
• Late-fall-run Number: This is same as winter-run above except for late-fall run.
