Eightmile Acclimation Pond was designed and constructed from 2017 thru 2018 on the Okanogan National Forest Eightmile Ranch, adjacent to the Chewuch River. One interrogation antenna will be located within the steel outlet structure. Up to two more antennas will be located at the terminus of the outlet pipe where it meets the Chewuch River, flows dependant. Acclimation of juvenile salmonids at this site will occur on a yearly basis. The interrogation system(s) are intended to monitor in-pond and smolt-to-adult survival rates and will be operational during release. Typical times of operation for this site will be March 15 thru June 1.

Interrogation event log for the 8-Mile Pond Acclimation Site (MEM)-2021 release

PIT tag interrogation system (Antenna A1) for the 8-Mile Pond began on 04-28-2021 at 1200 hrs. Antenna (A1) was located on the pond outlet structure. Antenna (A1) was moved downward accordingly with dropping pond levels. Antenna (A1) never moved and did not experience any lapse in coverage. A total of 14 files were downloaded throughout the interrogation period. The last download for this antenna occurred on 06-14-2021 at 1200 hrs. This antenna was removed after a period of no new unique PIT tag detections and a snorkel survey to confirm that the pond was void of hatchery Coho.

PIT tag interrogation system (Antenna B1) for 8-Mile Pond began on 04-28-2021 at 1200 hrs. Antenna (B1) was located approximately 15 meters downstream of Antenna (A1) and in the Chewuch River. Antenna (B1) was never moved. Antenna (B1) experienced a lapse in data collection between 05-18-2021 at 2250 hrs and 05-30-2021 1540 hrs due to a power connection failure. A total of 13 files were downloaded throughout release. The last download for this antenna, occurred on 06-17-2021 at 1300 hrs and removed shortly after.

Yakama Nation staff removed all remaining equipment during the month of June.
