JOH - Johnson Creek

JOH is a permanent PIT tag interrogation site on Johnson Creek. Johnson Creek enters the Okanogan River at RKM 65.3, in the town of Riverside, WA. The JOH site is located approximately 0.2 km upstream from the confluence of the Okanogan River. The site consists of a single 10 foot antenna anchored upright for pass-through detection. The antenna spans the wetted width of the channel at base flow. When installed in 2014 FST was equipped with an Allflex RM 310 reader and an Acumen data logger powered by batteries. In August 2018, the site was updated with a 10 foot HDPE antenna, IS1001 reader, and a linear power supply connected to grid power.
