IR2 - Lower Imnaha River ISA @ km 10
Status: Active - OperationalGeneral Operational Period: Year Round
Start Date: 11/13/2010 12:00 AM
In-stream detection system consisting of a single array located in the lower Imnaha River. The array (IR2) located at river km 10 (N 45.742839 W -116.764563) consists of one 10 foot and four 20 foot Biomark flat panel antennas that span the entire river at base flow. IR2 is operated by the Integrated Status and Effectiveness Project (ISEMP) cooperators Nez Perce Tribe and Quantitative Consultants, Inc. and was installed for continuous monitoring in November 2010. The array includes ISEMP standard site monitoring equipment including: air and water temperature probes, and a water pressure transducer to monitor stream level. Electrical power is provided by a solar/propane hybrid thermal electric generator and remote communication provided by a satellite modem.
