IR1 - Lower Imnaha River ISA @ km 7

Status:   Active - Operations Unspecified
Site Type: Instream Remote Detection System  |  Organization: Biomark
General Operational Period: Year Round
Start Date: 12/3/2010 12:00 AM

In-stream detection system consisting of a single array located in the lower Imnaha River. The array (IR1) located at river km 7 (N 45.761162, W -116.750658) consists of four 20 foot Biomark flat panel antennas that span the entire river at base flow. IR1 is operated by the Integrated Status and Effectiveness Project (ISEMP) cooperators Nez Perce Tribe and Quantitative Consultants, Inc. and was installed for continuous monitoring on December 3, 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.
