CHU - Upper Chiwawa River

This is a permanent instream PIT tag interrogation site at rkm 12 above Forest Road 62 and below Alder Creek on the Chiwawa River. The site consists of two rows of antennas, with each row spanning the wetted width of the channel during base flows. Each row consists of 3 15-foot PVC antennas, installed in flat-plate configuration. The FS1001M transceiver is powered by a thermoelectric generator. The antennas were built and installed by WDFW. A cellular modem is installed on site to provide remote communication and allow for automated data collection. A submersible pressure transducer and temperature probes are installed on site to monitor environmental conditions.
