OMF - Omak Creek above Mission Falls

OMF is a permanent PIT tag interrogation system located above Mission Falls in Omak Creek. Omak Creek enters the Okanogan River at RKM 51.5, approximately 1 KM upriver from the town of Omak, WA. The OMF site is located approximately 10.5 RKM upstream from the confluence of the Okanogan River. In March, 2015 the site consisted of a FS1001M running 4 pass-over PVC antennas, in two separate channel spanning rows. In March, 2018 the instream array was reconfigured with two 10 foot HDPE antennas anchored to the stream bed for pass-over detection. Antennas are arranged in a single row that spans the wetted width at base flow. Each antenna is power by a Biomark IS1001 reader multiplexed by an IS1001-MTS. Power is provided by a two 280 watt solar panels.
