Monitoring Recolonization After Dam Removal

The Mid-Columbia Fisheries Enhancement Group is partnering with USGS fish biologists to monitor the recolonization of the White Salmon River by salmon and steelhead after the removal of the Condit Dam in 2000. A screw trap placed in March 2017 at river mile 1.4 was checked regularly throughout the spring, filtering out juvenile fish heading downstream and storing them in a holding tank until they could be counted, measured, and injected with PITs (Passive Integrated Transponders) to relay their future movements.
