Interrogation Site Metadata

CIC - Cottonwood Island, Lwr Col Rvr

Status:   Decommissioned
Site Type: Instream Remote Detection System  |  Organization: U.S. Fish and Wildlife Service
General Operational Period:
Start Date: 5/1/2010 12:00 AM
End Date: 6/30/2010 12:00 AM

The Cottonwood Island site is located upstream of the Cowlitz River, near Longview, WA. The goal at this site is to detect juvenile fish that may take refuge in off channel areas during their migration. There are three multiplexors at this site with each MUX driving two parallel arrays of three antennas each. The 3' x 10' hybrid antennas are designed to allow fish to pass both through the antennas and over the top of them depending on tidal flux. Because the antennas can pivot up and down with the tidal flux they are capable of sampling the entire water column. Each pair of antenna arrays is deployed approximately 60-90' offshore from its MUX at high water.
