OMK - Omak Creek Instream Array

Status:   Active - Operational
Site Type: Instream Remote Detection System  |  Organization: Colville Confederated Tribes
General Operational Period: Year Round
Start Date: 1/1/2006 12:00 AM

OMK is a permanent PIT tag interrogation system in Omak Creek. Omak Creek enters the Okanogan River at RKM 51.5, approximately 1 km upstream from the city of Omak, WA. OMK is located 0.24 km from the confluence with the Okanogan River. In February 2011, the site consisted of 6 pass-over PVC antennas, in two separate rows. In January 2018, the instream array was reconfigured with four 10 foot HDPE antennas anchored to the stream bed for pass-over detection. Antennas are configured in 2 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 connected to grid power to charging two battery banks which in turn power the detection system. OMK has remote communication abilities provided by a cellular modem.

6/9/2022 3:00:00 PM SiteUp

Reactivated circuit breaker, swapped batteries and replaced battery switcher. Site fully operational.

6/9/2022 12:00:00 AM SiteDown

Site lost power due to circuit breaker being flipped, draining the batteries. Site inoperable. 

4/13/2021 1:00:00 PM General Ghost tag removed from antenna 03 field. Tag 3DD.003D378016
4/7/2021 10:00:00 AM General Ghost tag lodged itself within antenna 03 field causing 80% noise.
5/21/2018 1:00:00 PM SiteUp All equipment was reinstalled, the site is back online.
