2006 1/1/2006 12:00 AM 1/1/2007 12:00 AM The full-flow antenna (01) was inoperable from midday May 31, 2006 to June 9, 2006. That antenna had been experiencing trouble with low power (<2 amps) and will be repaired during the summer. Sullivan Plant interrogator was taken off-line on June 9, 2006 at 0730 (PDT). The plant was shut down for construction of a new bypass system remain shut down until late October. Antenna 51 was activated at the bypass entrance on Nov. 1. Antenna 51 (at the bypass evaluator station) was activated on Dec. 4.
2005 1/1/2005 12:00 AM 1/1/2006 12:00 AM The PGE Sullivan Plant was off line July 11 - 22 for plant maintenance and installation of a new juvenile PIT tag antenna in the bypass upstream of the present antenna.

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 Log Summary

Event Date Event Type Comments
5/26/2020 9:23:00 AM SiteDown From May 22-26, flows through the North Fish bypass (NFB) were reduced to deal with large amounts of floating algae affecting operations of Sullivan power plant. From May 26- June 1, NFB was dewatered to deal with the algae issue. Detection's were greatly reduced during the flow reduction in May.
8/27/2018 1:27:00 PM General Power plant was offline from August 27-30. Reduced flow (or no flow) resulted in limited or no fish passage through the facility. No fish detections during this period.
7/3/2018 1:27:00 PM General Power plant was offline from July 3-24. Reduced flow (or no flow) resulted in limited or no fish passage through the facility. No fish detections during this period.
7/17/2017 12:44:00 PM SiteDown Sullivan powerhouse shutdown during construction. Powerhouse dewatered entire construction period; no detections. Offline July 17-November 6.
3/13/2017 12:00:00 AM SiteDown Sullivan plant and fish bypass shutdown for maintenance from 3/13/17 to 4/28/17. No fish detection at either antennas during this period.
7/20/2016 1:52:00 PM SiteDown Main computer shutoff for 12 hours. Unknown reason. backup computer running. No data loss.
7/8/2016 1:21:00 PM General Interrogation files not uploading. Issue with Wifi. Interrogation files will be manually uploaded until issue with Wifi is resolved. Uploads will occur monthly.
5/17/2016 1:21:00 PM General Switched to Wifi modems to upload interrogation file to PTAGIS
8/29/2014 11:00:00 AM SiteDown Transceiver/antenna on turbine 13 was on, but stopped collecting tag codes on 8-29-14 @ 11:07. It appears that this transceiver was not operating from Aug 29- Dec 31. North Fish bypass antenna/transceiver was operational during this period.
5/7/2014 3:22:00 PM General BioMark replaced an FS1001A transceiver on North Fish bypass with a new FS2020 transceiver. Transceiver is setup to only detect full duplex tags.
2/13/2014 10:20:39 AM General Computers were offline due to battery backup failure and subsequent failure of the backup computer. Computers were offline 9/22/13 12:00 to 10/4//13 12:00 and 10/5/13 09:00 to 10/17/13 11:38. Transceiver buffers were downloaded and the first offline period (9/22-10/4) tag detections were submitted to PTAGIS. The second period (10/5 -10/17) will be submitted in the near future.
