Interrogation Site Metadata

MEW - Early Winters Acclimation Pond

Status: Active - Non-Operational

Site Type: Monitored Fish Release | Organization: Yakama Nation

General Operational Period: Seasonally
Start Date: 5/3/2019 12:00 AM

Two kidney bean shaped ponds were designed and constructed from 2017 thru 2018 on the Freestone Inn at Wilson Ranch and adjacent to Early Winters Creek and 30 meters south of HWY 20 in Mazama, WA. The antennas are located at the outlet structures of both ponds and in Early Winters Creek at the outlet pipe. Outlet pipes from both ponds join in a common gallery before flowing back into Early Winters Creek. Acclimation of juvenile salmon at this site will occur on a yearly basis. One antenna will be used at the outlet of each pond that has PIT tags. Two antennas will be used in Early Winters Creek where the outlet pipe is located, dependant on creek flow. The interrogation systems are intended to monitor in-pond and smolt to adult survival. The antennas will be operational during release. Typical times of operation for this site will be March 15 thru June 1.
