This is a permanent instream PIT tag interrogation site at rkm 4 located at the old fish weir. 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 20-foot HDPE antennas, installed in flat-plate configuration onto the old weir decking. The original FS1001M transceiver was replaced with an IS1001MC in October 2023. It is powered by a solar array and an Outback charge controller. 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. Site has a usual operation window of March to early/mid November depending on solar conditions.
