LWN - Little Wenatchee River

Status:   Active - Operational
Site Type: Instream Remote Detection System  |  Organization: Washington Dept. of Fish and Wildlife
General Operational Period: Year Round
Start Date: 6/23/2009 12:00 PM

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 PVC antennas, installed in flat-plate configuration onto the old weir decking. The FS1001M transceiver 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.
