Objective
To determine spatial and temporal distributions◦ immigration period (spring)◦holding period (spring through fall)◦spawning period (fall)
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
Methods
Passive TrackingActive 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

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

Summary
Individual movement patterns were diverseFish held in the DPD plunge pool1/3 of the Chinook tagged were tracked in the
Narrows ReachAll fish tracked above DPD were detected at
or above Hwy 20 during the spawning period
