JO2 - John Day North 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 north fish ladder at John day dam with antennas installed 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.

2018 2/14/2018 11:30 AM 12/4/2018 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 JDALD2.


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.

Event Date Event Type Comments
8/22/2021 9:21:39 AM ErrorsCleared The noise report did not show any increase in noise that is of concern. 
8/18/2021 9:17:02 AM ErrorsCleared The system experienced a couple small noise spikes in a short time span before returning to normal noise levels. The readers ability to detect PIT tags and timer tags was not impacted by the noise.
8/10/2021 11:14:44 AM ErrorsCleared Short noise event.
8/6/2021 8:25:15 AM ErrorsCleared This alarm was tripped due to a single noise event that lasted only a couple hours. The noise was seen on the trends noise peak but it wasn't enough noise to alter the average noise trend. The noise did not impact the readers ability to read PIT tags or timer tags.
7/30/2021 7:08:44 AM ErrorsCleared Noted.
7/27/2021 7:09:55 AM ErrorsCleared Noted.
7/25/2021 10:23:51 AM ErrorsCleared Noted.
6/30/2021 7:35:34 AM ErrorsCleared High temp alarms not uncommon this time of year.
6/29/2021 7:16:48 AM ErrorsCleared High temp not uncommon this time of year.
6/28/2021 8:03:27 AM ErrorsCleared High temp not uncommon this time of year.
6/27/2021 10:32:22 AM ErrorsCleared Common alarm this time of year

6/16/2021 7:28:38 AM TASS Enabled
6/8/2021 1:01:59 PM General Checked transceivers for tune. No problems to reportr.
6/3/2021 11:51:13 AM General Checked transceivers for tune. Cleared M4 alerts.
5/20/2021 12:20:00 PM General On site for GMC. Checked transceiver tuning., Cleared M4 alerts. Transceivers are currently reading with high efficiencies.
4/6/2021 7:41:21 AM TASS Memory alarms do not impact the detection efficiency of the transceiver. The noise alarms were a brief spike of noise which has subsided. All transceivers are operating with high efficiencies at this time.
3/29/2021 7:38:18 AM TASS Noted
3/20/2021 11:11:50 AM TASS Noted
3/15/2021 7:48:20 AM TASS Caused by power outage.
3/14/2021 5:00:00 PM General A power outage occurred 3-14-2021 from 0612 to 1454. The DCP remained on UPS power until 1004, but the transceivers only remained on UPS power until 0855. No data exist to fill the remaining data gap.
3/6/2021 9:46:47 AM TASS No apparent noise was captured on the noise report.
3/6/2021 9:46:36 AM TASS Noted
3/4/2021 7:45:31 AM TASS No apparent noise was captured on the noise report.
