CRU is a permanent instream PIT tag interrogation site at RKM 28.35 on the Chewuch 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 three 20-foot PVC antennas, installed in flat-plate configuration. Each antenna is powered by a Biomark IS1001 (ACN) and the ACNs are connected to a Biomark IS1001-MC (MTS). The antennas were built and installed by WDFW. The site is powered by a thermoelectric generator. CRU has remote communication abilities provided by a cellular modem and Campbell Scientific CR1000 datalogger. A submersible pressure transducer and temperature probe sensors are also installed to provide environmental condition data collection.
