LMJ - Lower Monumental Dam Juvenile

Status:   Active - Operations Unspecified
Site Type: Juvenile Fish Bypass Facility  |  Organization: Pacific States Marine Fisheries Commission
General Operational Period: Seasonally
Start Date: 4/25/1993 7:42 PM

This site monitors the Lower Monumental Dam smolt bypass and sampling facility. The site operates seasonally for juvenile outmigration and includes antennas in the full flow bypass flume that is often active before and after the sampling facility each year. Separation by Code (SbyC) is also available to allow researchers to selectively divert PIT-tagged fish. SbyC acts on all PIT-tagged fish by default to return them to the river, rather than be collected for transportation with untagged run-of-river fish. Researchers can use SbyC to override that default action and instead allow PIT-tagged fish to be treated like the untagged population.

Due to high numbers of fish, the B-side was placed into secondary bypass from 05:15-08:00 PDT on April 24. Fish were bypassed from 1500 June 24 through 1500 June 26 due to lock outage at Ice Harbor Dam. Barge transportation and ended on July 30. Truck transporation ran from August 1 - 3.

Sampling for fish condition occurred every third day from April 1 - May 4. Collection for transport ran from May 7 - October 1, when the facility was returned to primary bypass. The full flow was dewatered on December 17.
2012 3/21/2012 9:00 AM 12/18/2012 9:00 AM The facility watered up in primary bypass on March 21. Sampling began on April 3 and continued every 3rd day after that. Collection for transportation started on May 5 and ended on October 1, along with sampling. The facility was placed into primary bypass until December 18, when the full flow was dewatered.
2011 3/14/2011 12:00 PM 12/19/2011 2:00 PM The primary bypass watered up on March 14; PIT tags can be detected on the full-flow antennas 01-04. The Juvenile Fish Facility was watered up on March 28. A sample was taken every three days until collection for transportation started on May 8. Collection was suspended and the facility switched to primary bypass due to high flows between May 16 and 18. Facility switched into primary bypass on October 1. The facility dewatered for the season on December 19.
2010 3/23/2010 12:00 PM 12/21/2010 1:45 PM The juvenile fish bypass system watered up in primary bypass mode on March 23, 2010. In primary bypass mode, PIT-tagged fish are detected only at the full-flow antennas before they are routed back to the river. The facility switched to secondary bypass, passing fish over the separator, on April 1. A condition sample was taken every three days during April. Collection for transportation commenced on May 3, and continued through October 1. LMN switched back to primary bypass mode at 0700 (PDT) on October 1, and remained in primary bypass until the facility's scheduled dewatering on December 21.
2009 3/18/2009 3:00 PM 12/16/2009 3:00 PM The primary bypass pipe watered up on March 18. The facility switched to secondary bypass on April 1, routing fish over the separator and, periodically, through the collection facility for sampling purposes. Collection for general transport began on May 8 and continued until October 1, at which time the facility returned to primary bypass. The primary bypass pipe was dewatered on Dec. 16.
2008 1/1/2008 12:00 AM 12/18/2008 9:00 AM The full-flow transport pipe was dewatered between Jan. 2 and Mar. 19. Fish were first put over the separator at 7AM (PDT) on April 1. Lomo began transporting fish on May 12. The site switched from transportation to secondary bypass on May 19, due to high flows. Any fish (including those with PIT-tags) routed to the raceways after 7:55 PM (PDT) on May 18 were discharged from the raceways back to the tailrace just after 5PM on May 19. Collection for transportation resumed at 3PM (PDT) on May 23; all fish sampled on May 23 were also transported. The facility was placed in primary byass (full-flow PIT tag detection only) on Sept. 30. The juvenile fish bypass was dewatered for the season on December 18.
2007 3/19/2007 2:00 PM 1/1/2008 12:00 AM The full flow bypass pipe at LMN watered-up on March 13, 2007. The new PIT tag detectors on the full flow bypass pipe were enabled on March 19. The JFF watered-up in secondary bypass mode at 0700 (PDT) on April 1; all fish passed through PIT tag detectors in the JFF as they were routed back to the river. Transportation activities began on May 11, and continued until the site switched back to primary bypass mode at 0700 (PDT) on October 1. The site remained in this mode until the full flow bypass dewatered in December.
2006 4/1/2006 7:00 AM 9/30/2006 6:00 AM The facility watered-up at 0700h on April 1, 2006. The facility operated in secondary bypass mode until 0700 on April 28, when fish were first routed to the raceways for subsequent transportation. LMN shifted back to primary bypass on Sept. 30. There was no PIT tag detection capability in the primary bypass route at LMN in 2006, so there was no way to track any PIT-tagged fish diverted from the LMN turbine intakes after this date.
2005 4/1/2005 6:00 AM 10/1/2005 6:00 AM The Juvenile Fish Facility went on Primary Bypass (bypass just above the separator) from 0210 to 1235 (PDT) on May 14, and from 0800 to 1300 on May 15, to keep from overloading the raceways.

On site for weekly gate checks. The electric cylinder slide gates were cycled and the tuning was checked in the PLC. B gate seemed to have a little more resistance than usual so the gate channel what cleaned with a towel and a dab of WD40 for the cylinder seal.

Lights at full flow are definitely the cause of the night time increased noise levels on the full flow. Site bio is issuing a work order to have electricians check and fix lights. It might be awhile due to staffing issues.
