Twisp Acclimation Pond is Douglas County PUD owned and WDFW operated. This pond is a man-made, remote acclimation pond located approximately 6 miles west of Twisp, WA. Acclimation of juvenile salmon at this site occur on a yearly basis and between March 1 and June 15, depending on species. The interrogation site is comprised of two IS1001 and one AllFlex detection systems installed within the outlet channel to the Twisp Acclimation Pond. The outlet channel is approximately 10 meters in length. Interrogation systems are installed just prior to release and are taken out when all hatchery juvenile fish have left the facility. The interrogation systems are intended to monitor in-pond and smolt-to-adult survival rates.
