CRW - Chewuch River above Winthrop

This is a passive in-stream interrogation system on the Chewuch River at river km 1, above Winthrop, WA. The system consists of two arrays of three antennas each. The arrays span most of the channel. The arrays are in tandem to provide directionality data and increase detection probability. All antennas are anchored in a pass-by configuration. Antenna 1 and antenna 4 are 30 ft antennas made up of two sectional 15 ft pieces. Antennas 2, 3, 5 and 6 are 20 ft antennas.
