SA1 - Salmon Creek Instream Array

Salmon Creek enters the Okanogan River at RKM 41.3, in the city of Okanogan, WA. The site was originally located 2.9 km upstream from the confluence with the Okanogan River, and originally consisted of 3 pass-over 7 foot PVC antennas powered by a FS1001M transceiver. Two of the antennas were damaged in spring/summer 2016 and subsequently removed. In February 2017, a second antenna was again added at the site. In January 2018, the site was moved approximately 1 km downstream and reinstalled with 4 new 20 ft HPDE antennas with an IS1001 master controller. Power is provided by Thermal Electric Generator (TEG).
