2013 3/1/2013 12:00 AM 10/31/2013 2:05 PM Channel was watered down between September 1 and October 11. It was operated intermittently from October 11-31 primarily at night to facilitate USACE repairs and PIT tag anntenna testing.

2011 3/3/2011 7:20 AM 9/1/2011 7:30 AM The B2CC was open from 0731 until 1547 on 09 February to flush debris; the PIT tag detector was not active during this brief interval. B2CC watered up for two days, March 3-4, for kelt fallback testing; the BCC transceiver was active during these tests. The B2CC flume was then dewatered from March 4 until March 14. The BCC channel was dewatered for the season on September 1.
2010 3/14/2010 6:45 AM 8/31/2010 3:00 PM The corner collector flume watered-up for the 2010 season on March 14. It was shut down for approximately 20 hours from 10:40 on March 16 until 7:00 on March 17. The flume was dewatered for 54 hours from 6AM PST on April 20 until noon (PST) on April 22. The flume was closed for 20 hours from April 26 at 12:30 PM (PST) to April 27 at 9:45 AM due to a broken BGS cable and no boat protection. The flume was dewatered at the end of the spill season on August 31.
2009 4/3/2009 6:30 AM 9/3/2009 8:00 AM The BCC flume watered up on April 3 and operated without operation until Sept. 1, when dewatering activities began. The flume was fully dewatered on Sept. 3.
2008 3/6/2008 12:00 PM 9/1/2008 6:50 AM The Bonneville PH2 Corner Collector channel (B2CC) watered-up briefly a few times between late February and early March to pass debris, but was not operated consistently, nor was the transceiver initialized, until March 6. The Corps regularly dewatered the B2CC between March 6-21 to allow researchers to get to their equipment. The B2CC was dewatered, and the BCC transceiver disabled, between March 21 at 13:35 and March 24 at 9:04. The B2CC was dewatered at the end of the fish passage season on September 1.
2007 3/1/2007 1:30 PM 8/31/2007 1:00 PM The Corner Collector channel watered up on March 1, 2007. The channel was dewatered for the year on August 31.
2006 4/13/2006 8:00 AM 11/21/2006 9:00 AM New installation. First year. Opened for the season at 0815 on 13 April. The channel was shut down for the season around 16:00 PDT on 8/31/06. However, PIT tags were somehow detected through noon on September 1. The bypass channel was unexpectedly re-watered at 10:45AM on November 15, to pass trash and debris in the BON-PH2 forebay. The PIT tag system was re-activated at 11:30am on Nov. 16. The bypass was dewatered at ~8:30am on Nov. 21. The PIT tag detector was active during this interval, but no tags were detected. The B2CC was watered up between 12/21-26/06 to pass debris during ladder dewatering; the PIT tag detector was not activated during this interval.


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.

On site to replace D1's main air recirculating fan motor. The system had another flow failure alarm days before so the motor was deemed as the culprit. The air filters for the system were replaced for both units. A spare flow sensor, fan assembly with motor, and replacement filters were left for future use. D1 was running great when I left.

5/25/2022 1:00:00 PM General

On site to investigate a "No Flow" alarm for D1 on the dehumidification system. When I first started D1, the unit made a loud humming noise. I opened it up to find the main motor not blowing air but vibrating. After shaking the motor housing, it began to quiet down and begin blowing air. I stopped and started the unit many times and noticed the initial start of the unit was louder than the other unit but it did quiet down and begin blowing air as expected. The motor for the unit is to be replaced soon.

While on site, I replace D1's flow sensor. I tested the existing sensor and everything seemed to be fine with it. I replaced the sensor in case it was an intermittent problem with the sensor, I wanted to be able to eliminate that concern moving forward.

It was noticed that files for M4 were not being submitted after the platform changeover last week. The automatic upload was disabled in the configuration. This was changed on both IPC PC's today.

2/3/2022 2:00:00 PM General

The antenna testing tool known as ARRT (automatic read range testing), was upgraded. The PLC and user interface to control the ARRT testing system was upgraded due to obsolete equipment with the older system. The new system also has some more features for future testing and is more user friendly for personnel running the test.

Per Site Bio,

Yes, we have the B2CC locked out and tagged out for maintenance and repair. Part of the lockout process was to disable the PIT system, including the battery backup. I’m sorry this info was not relayed to you guys. I suspect this maintenance work will go for 2-3 weeks with absolutely no flow down the corner collector while people are in there with equipment
