We installed and operated a prototype fixed site monitoring system to detect migrating adult PIT tagged salmonids in the tidal freshwater portion of the Columbia River estuary during 2011-2012.  Detections were used to evaluate arrival timing and subsequent timing and survival to detection locations upstream.  The system was installed during August 2011 at the terminus of a pile dike structure (PD7) at rkm 70.
