This site is a permanent instream PIT tag detection system located at rkm 0.4 on Chiwaukum Creek (Wenatchee River Basin), located near Tumwater Campground (access through site 51). The site consists of two rows of antennas, each row with three 10 foot antennas, installed in a flat plate configuration. Each row spans the wetted width of the channel during base flows. The antennas were built and installed by WDFW. Power to the FS1001M transceiver is provided by a thermoelectric generator on site.
