JO1 - John Day South Fish Ladder

Status:   Active - Operational
Site Type: Adult Fishway  |  Organization: Pacific States Marine Fisheries Commission
General 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.

Operational History

Operational history describes the period the site was interrogating for PIT tags. The comments provide anecdotal information about the operation of the site during this period. Site operational periods are updated typically at the end of the calendar year.

Year Start Date End Date Comments
2021 1/1/2021 12:00 AM 1/1/2022 12:00 AM Ladder dewatered between January 20 and February 25.
2020 1/1/2020 12:00 AM 1/1/2021 12:00 AM Ladder was dewatered January 28 - March 27.
2019 1/1/2019 12:00 AM 1/1/2020 12:00 AM Ladder dewatered January 22 - March 8.
2018 2/14/2018 11:30 AM 1/1/2019 12:00 AM Automated data submissions started Feb 14. Prior to this one weir wall was collecting detections to transceiver buffers, which were downloaded weekly and submitted as Passive Recaptures.
2017 Construction and installation of antennas was completed before all necessary communication and wiring was installed. Antennas on one weir wall were run and collected detections to transceiver buffers which were downloaded approximately weekly. These detections were submitted as Passive Recaptures from site JDALD1.


Configuration metadata includes details about the equipment used at the site to detect and record PIT tags. A new configuration sequence record is created when equipment is added or removed from the site and the period of time it was active. A configuration sequence without an End Date is currently active.

PSMFC and GorgeNet were on site yesterday to solve communication issues that had been going on since last Friday. The site was collecting data during the comms outage so no data was lost. The ethernet cable that plugs into the radio at the ladder had come unplugged. It was reseated and secured to the tower so as to not come unplugged. 

12/12/2021 9:40:08 AM ErrorsCleared Communication error. Needed to restart M5 services.
