Biomark installed a temporary PIT-tag detection system in the right-bank fish ladder at Wanapum Dam, Columbia River in April 2014.  Installation of the system was in response to emergency operations put in place at the dam.  The purpose of the system was to monitor timing of fish through the fish ladder.  The detection system utilized our IS1001 reader platform.  The IS1001-MC and IS1001s were housed in NEMA 4X enclosures secured to the deck of the dam.  Diagnostic and tag detection data was stored on the IS1001-MC and retrieved manually. Antennas were secured to the downstream face of two separate weirs.  Each weir had two orifices, but one orifice of each pair was closed.  Ramp structures on the bottom of the antennas minimized hydraulic disruption and eliminated the need to remove concrete.  The system operated successfully during the 2014/2015 fish migration period and was removed during the following in-water work period.
