2001 4/1/2001 12/10/2001
2002 4/2/2002 12/11/2002
2003 3/31/2003 10/30/2003 Primary Bypass was activated on March 31. Except for brief intervals, the secondary bypass was also operational between March 31 and September 30. On September 30, the secondary bypass was deactivated; subsequently, all fish were routed directly back to the river (after passing through the full-flow coils, 01-04). On October 30, the primary bypass was disabled and fish were subsequently discharged through the emergency bypass (at the North end of the powerhouse). This route is not monitored for PIT tags.
2004 4/1/2004 12/14/2004 The McNary JFF began operating in Primary Bypass on April 1, 2004, and switched to Secondary Bypass on April 2. The facility continued to switch between bypass modes on alternating days until June 23, when the facility locked into Secondary Bypass (transporting 100% of non-PIT-tagged fish). Except for brief intervals, the JFF remained in Secondary Bypass until September 19, when it switched back to Primary Bypass mode. The transportation and sampling facilities were dewatered for the season on September 19. PIT tag detection continued on the four coils of the Full Flow (Primary) Bypass until noon on December 14, when the facility switched to Emergency Bypass (through the North end of the powerhouse, away from the JFF) in preparation for the winter maintenance period.
2005 3/28/2005 12/6/2005 The McNary collection channel was watered up on March 28, but flow was not concentrated through the Primary Bypass flume until 1:00PM on March 29, 2005. At 0700 hours April 2 the facility was placed in secondary bypass. The facility cycled between primary and secondary bypass on alternate days between April 2 and June 23. MCN remained in secondary bypass (collection mode) until September 16, when it returned to primary bypass. The primary bypass flume was dewatered at 1230 on December 6.
2006 3/30/2006 11/28/2006 The McNary Juvenile Fish Facility (JFF) began operation in emergency bypass on March 21. On March 30 at noon, the facility was switched to primary bypass operation, which routes fish through the main pipe and full flow PIT tag detectors then back to the river. Beginning at 7:00AM (PDT) on April 1, the facility was placed in secondary bypass on alternate days, to collect fish for enumeration and to evaluate condition. The facility switched out of primary bypass on July 6, into secondary bypass and collection for transportation. Transportation (and sampling) activities concluded on September 14, and the facility ran in primary bypass mode until Nov. 28, when freezing weather forced the facility to switch to the emergency bypass exit. No PIT tag detection capabilities exist at the McNary emergency bypass.
2007 3/28/2007 10/19/2007 The McNary juvenile fish bypass watered-up into primary bypass on March 28, 2007. MCJ switched to emergency bypass at 1PM PDT on April 2, back to primary bypass at 10AM PDT on April 6, and began collection for sampling (secondary bypass) at around 4PM on April 6. Between April 6 and August 16, the facility collected fish for sampling every other day. On August 17, the facility began collecting and transporting fish, and operated in secondary collection mode every day until September 14, when the collection season ended and the facility was placed in primary bypass. It remained in this mode until October 19, when a mechanical failure at the primary dewatering screen resulted in a switch to emergency bypass. The facility remained in this mode until the collection channel was dewatered at the end of the year.
2008 3/31/2008 11/19/2008 The McNary JBS full-flow watered up into primary bypass beginning at 10:30 AM (PST) on March 31, 2008. A failure of the primary dewatering system required the facility to switch to emergency bypass for about 30 hours on June 30 and July 1, during which no fish passed through the MCJ detection system. McNary began collecting fish on July 16 to transport (by barge) on alternating days, beginning July 17. Transportation ended on Sept. 25, and the facility reverted to primary bypass. The PIT tag detection season ended when the primary bypass pipe was dewatered on Nov. 19.
2009 3/31/2009 12/3/2009 The McNary JBS watered up in primary bypass on March 31, 2009. The secondary bypass was activated for sampling on alternating days beginning April 8. McNary began collecting for transportation on July 16. On July 23 McNary switched back into primary bypass due to high water temperatures, and all fish held in the raceways were released back to the river. McNary resumed collection on July 24, but transported the collected fish every day. The facility went to primary bypass on Sept. 30. The facility went to emergency bypass on Dec. 3, ending PIT tag detection activity for the year.
2010 4/1/2010 11/22/2010 The McNary Juvenile Fish Facility (JFF) watered up in primary bypass on April 1. However, installation of the extended-length submersible bar screens (ESBSs) was delayed to aid juvenile lamprey passage; salmonid passage through the JFF was volitional until screen installation was completed on April 14. The JFF operated in secondary bypass mode on alternate days between April 6 and July 14, and daily after that until secondary bypass was discontinued on October 1. After Oct. 1, the site operated in primary bypass, but switched to emergency bypass (no PIT tag detection) for about 45 hours on Oct. 26-28. The facility switched to emergency bypass again on Nov. 22, due to extremely cold weather, ending PIT tag detection activities for the year.
2011 3/27/2011 11/18/2011 The Juvenile Fish Facility (JFF) watered up in primary bypass on Mar. 27. The JFF operated in secondary bypass on alternating days from Apr. 6 until July 20, when the facility went into transport mode. The JFF went into primary bypass mode on September 30. The facility was put into emergency bypass on November 18 and will remain out of service until spring 2012.
2012 3/29/2012 11/5/2012 Data collection computers shut down and removed March 1-23 to accomodate construction activities required for the outfall relocation project. Watered up in primary bypass on March 29. The JFF went into emergency bypass from April 3-9, when it switched back into primary bypass. The facility went into secondary bypass on April 10. SMP samples being collected on even number days in April and May. The facility went into transport mode on August 17 at 6 am PST. Smolt Monitoring Sampling ended and the JFF was switched into primary bypass at midnight on September 31. The facility went into emergency bypass on November 5. The facility was shut down for the season on December 20.
2013 3/26/2013 11/27/2013 The facility watered up in primary bypass on March 26. Operations alternated between primary and secondary bypass, which allows for collection for sampling, on every other day. Collection for sampling concluded on September 30. McNary went into emergency bypass on November 27 ending PIT tag detection for the season.
