BVC - Beaver Creek, Methow River

This is a permanent instream PIT tag interrogation site on Beaver Creek in the Methow River Basin. From 2009 until 2014, the site was located at river kilometer 3 and had 6 antennas in 3 rows. In July 2014, the site was burned over by a wildfire and removed. In March 2015, the site was reinstalled 2 kilometers downstream from the original location. The new site configuration consists of three 10-foot PVC antennas, with each antenna spanning the wetted width of the channel during base flows. There is an upstream, middle, and downstream antenna installed in flat-plate configuration. The antennas are operated by a FS-1001M (MUX) unit. The antennas were built and installed by WDFW. The site is connected to grid power to charge the battery bank powering the detection system. BVC has remote communication abilities provided by a cellular modem and a QuBE datalogger.
