WSH - Warm Springs Hatchery

Originally installed in 2008 with two antennas powered by an FS1001M multiplexor, this site monitors the adult fishway at Warm Springs National Fish Hatchery. In April 2018, the mux was replaced with an IS1001 master controller and dual detection mode was enabled. In June 2018, a third antenna was added to the site to monitor the lamprey passage system.
