SFL - Shipherd Falls Ladder

Status:   Decommissioned
Site Type: Instream Remote Detection System  |  Organization: Washington Dept. of Fish and Wildlife
General Operational Period:
Start Date: 4/11/2009 2:55 PM
End Date: 10/31/2010 4:15 PM

This site is located at Shipherd Falls adult fish ladder, on the Wind River near Carson, WA. The PIT tag interrogation antennas are installed in series in the second and third slots below the adult fish trap. Antenna F1 is upstream of antenna F2. All fish migrating up the fishway pass through these antennas prior to reaching the adult fish trap. When both the interrogation site and trap are in operation, tagged fish that successfully pass the antennas and enter the trap will therefore be logged as interrogations and recaptures in the trap. When the trap is out of operation (May-early June), the tagged fish will be interrogated only. During the winter, when the trap is in operation but the antennas are not, PIT-tagged fish will be reported as recaptured only.
