SC1 - Lower SF Clearwater R at rkm 1
Status: Active - OperationalGeneral Operational Period: Year Round
Start Date: 8/18/2011 12:00 AM
Instream detection system located in the lower South Fork Clearwater River. The site is located at river km 0.9 consists of a single array of seven 20-ft Biomark HDPE antennas. The array spans the entire channel during low flow conditions. SC1 is operated by the Nez Perce Tribe and Biomark and was originally installed for continuous monitoring on August 19, 2011, with a FS2001M and six antennas. The site was upgraded to an IS1001-MTS on September 19, 2019. The array includes air and water temperature probes, and a water pressure transducer to monitor stream level. Electrical power is provided by grid power and remote communication provided by a cellular modem.
