LMR - Lower Methow River at Pateros

LMR is a permanent instream PIT tag interrogation site on the Methow River. When first installed with a single row of six antennas, it was located near the WDFW Miller Hole access site at about river kilometer 3. In December 2010, a second row of six antennas was added to the site. In August 2017, the site was relocated 5 kilometers upstream and the two FS1001M transceivers were replaced with a single Biomark/QST QuBe controller. The site currently consists of two rows of antennas, with each row nearly spanning the wetted width of the channel during base flows. Each row consists of six 20-foot HDPE antennas, installed in flat-plate configuration. Each antenna is powered by a Biomark IS1001 (ACN) and the ACNs are connected to a Biomark/QST QuBe controller. The antennas were built and installed by WDFW. The site is powered by a thermoelectric generator. LMR has remote communication abilities provided by a cellular modem. A submersible pressure transducer and temperature probe sensor are also installed to provide environmental condition data collection.
