MRW - Methow River at Winthrop

This is a passive in-stream interrogation system on the Methow River. During 2009 and early 2010, the array was located at river km 81, above Winthrop, WA near Winthrop National Fish Hatchery. In Sept. 2010 it was moved upstream to its new location below Wolf Creek on the mainstem Methow River, at river km 85. The system consists of two arrays of three antennas each. The arrays span the channel at low summer flows. The arrays are in tandem to provide directionality data and increase detection probability. All antennas are anchored in a pass-by configuration.
