LLC - Loup Loup Creek Instream Array

Status:   Active - Operational
Site Type: Instream Remote Detection System  |  Organization: Colville Confederated Tribes
General Operational Period: Year Round
Start Date: 3/7/2013 12:00 AM

LLC is a permanent PIT Tag interrogation system on Loup Loup Creek. Loup Loup Creek enters the Okanogan River at RKM 27.2, within the city of Malott, WA. LLC is located 0.42 km from the confluence with the Okanogan River. In June 2013, the site consisted of 3 PVC antennas anchored to the stream bed in pass-over configuration. In January 2018, the instream array was reconfigured with three 10 foot HDPE pipe antennas anchored to the stream bed for pass-over detection. Antennas are configured in 3 separate rows that span the wetted width at base flow. Each antenna is power by a Biomark IS1001 reader multiplexed by an IS1001-MC. The site is on grid power running a linear power supply that in turn powers the detection system. LLC has remote communication abilities provided by a cellular modem.
