OBF - Omak Creek below Mission Falls

Status:   Active - Operational
Site Type: Instream Remote Detection System  |  Organization: Colville Confederated Tribes
General Operational Period: Seasonally
Start Date: 2/29/2016 12:00 AM

Omak Creek enters the Okanogan River at RKM 51.5, approximately 1 KM upriver from the town of Omak, WA. The OBF site is located approximately 9.90 KM upstream from the confluence of the Okanogan River, and 110 meters downstream of the base of Mission Falls. The setup consists of one row of two flat-plate 10ft HDPE antennas anchored to the substrate. The row spans the wetted width of the channel at base flows. The antennas are controlled by two 12-volt IS-1001 reader boards synced to one another, each connected to a Bluetooth data logger. The site is run on two 12v 100ah batteries in parallel and charged by a 100 watt solar panel via a Renogy Rover charge controller. The site is operated seasonally, shutting down when solar cannot keep up with energy demands in the winter.
