Start Date: 4/17/2008 12:00 AM

This is a permanent instream PIT tag interrogation site at rkm 1 located on lower Nason Creek. The site consists of two rows of antennas, with each row spanning the wetted width of the channel during base flows. Upstream row consists of 1 20-foot, 1 15-foot and 1 10-foot PVC antenna. The downstream row consists of 1 10-foot and 2 20-foot PVC antennas. All antennas are installed in flat-plate configuration. The FS1001M transceiver is powered by grid. 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.
