Site Name


ANT - Antoine Creek Instream Array

Antoine Creek enters the Okanogan River at RKM 98.5, approximately 6 km upstream from the city of Tonasket, WA. Site ANT is located on Antoine Creek, 0.48 km upstream from the confluence with the Okanogan River. The site consists of 3 pass-through HDPE antennas accompanied by individual IS-1001 reader boards in series. Antenna sizes are as follows (upstream to downstream): Ant1 6 feet, Ant2 6 feet, Ant3 10 feet. The site is on grid power. Two banks of 12volt batteries in series create 24volts to run the MTS-MC unit. The batteries are connected to a timer switcher that will switch battery banks every four hours. The battery bank not running the MTS unit is then charged to capacity using a three-stage battery charger. A bioprobe collects and stores both air and water temperatures as well as the water depth data. The ANT site has a Cloudgate 4G cellular modem which transmits data to PTAGIS and Biologic.
