BBT - Touchet River at Bolles Bridge

BBT is a permanent instream PIT tag interrogation site located approximately 200 feet above the State HWY 124 bridge on the Touchet River, near Bolles Road, at River Kilometer 65.2. The site consists of two rows of antennas, with each row nearly spanning the wetted width of the channel during base flows. Each row consists of 3 20-foot HDPE antennas, installed in flat-plate configuration (the original flat plate antennas were replaced in 2018). Each antenna is powered by a Biomark IS1001 (ACN) and the ACNs are connected to a Biomark IS1001-MC (MTS), which was installed in 2018. Prior to that the site operated with a FS2001M multiplexor transceiver. The antennas were built and installed by WDFW. The site is powered by direct power from grid. BBT has remote communication abilities provided by a cellular modem.
