  1. Acoustic Telemetry: Adult Spring-Run Chinook Salmon on The Lower Yuba River LESSONS LEARNED PILOT STUDY MAY 12, 2009 – SEPTEMBER 13, 2009 Leslie Alber

  2. To determine spatial and temporal distributions • immigration period (spring) • holding period (spring through fall) • spawning period (fall) Objective

  3. Tagged 30 adult spring-run Chinook Salmon • Hook-and-line sampling • MAY 12, 2009 – MAY 26, 2009 • Vemco V13 transmitters via esophageal/gastric insertion • Random repeat intervals of 30-90 sec • Passive Tracking • Active Tracking • 19 VEMCO VR2W monitoring receivers • Yuba/Feather River Confluence  Narrows Reach (below Englebright Dam) • Maintained & downloaded by Jonathan Nelson and the Wild Trout crew • VEMCO VR100 mobile tracking receiver w/ VH110 directional hydrophone • Weekly surveys by boat (Narrows  Confluence) or foot (Narrows  Englebright) • May 20, 2009 – November 13, 2009 Methods

  7. Highest receiver upstream Lowest receiver downstream

  8. 24 Fish passed DPD

  9. The area between DPD and Hwy 20 was most likely used largely as a migratory corridor.

  10. By August 31, 2009 (date of first observed redd) 16 fish were detected at or above Hwy 20 • The remaining 8 fish were first detected in this section between September 1, 2009 and September 25, 2009 Below Hwy 20 Above Hwy 20

  13. Individual movement patterns were diverse • Fish held in the DPD plunge pool • 1/3 of the Chinook tagged were tracked in the Narrows Reach • All fish tracked above DPD were detected at or above Hwy 20 during the spawning period Summary
