UWE - Upper Wenatchee River

This site is a permanent instream PIT tag detection system located at rkm 81.2 on the Wenatchee River, near Plain, WA. The site consists of 6 20-foot antennas in a single row, installed in flat-plate configuration. The row of antennas spans the wetted width of the channel during base flows. The antennas were built and installed by WDFW. The site is powered by a thermoelectric generator. 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.
