Tunk Creek enters the Okanogan River at RKM 72.4. TNK is located approximately 50 meters 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, TNK was equipped with an Allflex RM310 reader. In March 2019, the site was updated with a 10 foot HDPE antenna, IS1001 reader, and solar panels to provide power to the 12V battery bank. The site is currently operated seasonally.
