JO1 - John Day South Fish Ladder
Status: Active - OperationalGeneral Operational Period: Year Round
Start Date: 2/14/2018 11:30 AM
This site monitors the south fish ladder at John Day Dam with antennas in the weir orifices and overflows of two weir walls. The antennas were installed February 2017 without dedicated communication and synchronization lines. Only the upstream weir antennas were active for the first year. During that time PIT tag detections were stored to the transceiver buffers and then submitted to PTAGIS as passive recaptures. The site became fully operational and began automated data submissions of interrogation data on February 14, 2018.
