EWC - Early Winters Creek rkm 0.36

This site is a permanent instream PIT tag detection system located at rkm 0.36 on Early Winters Creek (Methow River Basin), located near Early Winters Campground. The site consists of two rows of three antennas each (combination of 10- and 15-foot). All antennas are installed in a flat plate configuration. Each row of antennas spans the wetted width of the channel during base flows. The antennas were built and installed by WDFW. The site is connected to grid power to charge the battery bank powering the detection system. A Campbell Scientific CR-1000 data logger and cellular modem are installed on site to automate data collection and provide remote communication. A water temperature and pressure probe, and an air temperature probe are also installed on site to monitor environmental conditions. Site removed September 2017.
