1995 4/14/1995 4/26/1995 The Start_date and End_date values reflect the first and last dates of detection, respectively. The actual interval of operational dates is not known.
1996 4/15/1996 5/6/1996 The Start_date and End_date values reflect the first and last dates of detection, respectively. The actual interval of operational dates is not known.
2007 4/13/2007 5/15/2007 In 2007, there were two volitional releases at Chiwawa from Pond #2; the first release occurred between April 13-30, and the second release occurred between May 1-15. Between the volitional releases, there was a forced release from Pond #1 on May 1. All releases from both ponds were monitored for PIT tags.
2008 4/10/2008 5/13/2008 The volitional release from Chiwawa Pond began on April 10. All remaining fish were forced out on May 13.
2009 4/15/2009 5/13/2009 The volitional release of fish at Chiwawa Pond began on 4/15/09 at approximately 10:00 a.m. PST. In 2009, all tagged fish were released from a single pond. The remaining fish were forced or seined from the pond on May 13, 2009.
2010 4/14/2010 5/12/2010 The volitional release from the Chiwawa Ponds began on April 14, 2010. On 5/12/10, hatchery personnel seined the remaining fish out of the pond. During this seining process, several hundred (?) fish escaped over the dam, boards without going through the PIT tag antennas. Also, pushing thousand fish through the PIT tag system in a short period of time probably also adversely impacted the ability to read some of the PIT tagged fish. The volitional release officially ended at 10:00 am PST on 5/12/10. The fish were gone from the pond, and the PIT tag equipment was turned off.
2011 4/25/2011 5/20/2011 Volitional release from April 25 - May 19. All remaining fish were pushed out and ponds emptied on May 19 between 12:45 and 16:00.
2012 4/16/2012 5/2/2012 Volitional release began on April 17 and ran until May 1. Forced release started at 10:30 on May 1.
2013 4/24/2013 5/14/2013 Monitored spring Chinook release from April 16-22, but timestamp was lost so detections were reported as recaps in TLM1106.CHP. Monitored steelhead releases from April 24-May 14.
