Battle Creek Restoration Project implementation includes modification of facilities at Battle Creek Hydroelectric Project diversion dam sites located on the North Fork Battle Creek (North Fork), South Fork Battle Creek (South Fork), and Baldwin Creek in three phases (Phases 1A, 1B and 2).
Phase 1A includes installing fish screens and ladders at the North Battle Creek Feeder and Eagle Canyon diversion dams and removing Wildcat diversion dam and appurtenant conveyance systems on the North Fork; and constructing a fish barrier on Baldwin Creek near the Asbury Pumped Diversion Dam.
Phase 1B includes installing an Inskip Powerhouse tailrace connector and bypass on the South Fork, and Phase 2 includes installing a fish screen and ladder on Inskip diversion dam, installing a South Powerhouse tailrace connector, and removing Lower Ripley Creek Feeder, Soap Creek Feeder, Coleman and South diversion dams, and appurtenant conveyance systems.
December 2013 Status:
Phase 1A - The majority of fish screen and ladder construction has been completed at the Eagle Canyon and North Battle Creek Feeder (NBCF) diversion dams. As the result of hydraulic evaluations to test the new facilities (in 2012) and physical modeling of the NBCF fish ladder and screen (in early 2013), it was determined that modifications are necessary at the NBCF site to improve effectiveness of the fish screening and fish ladder passage, and for PG&E to meet their required canal diversion. Design work is underway and these NBCF modifications are planned to be implemented in 2015/2016.
At NBCF diversion dam, a contract was awarded to T.L. Peterson in July 2013 for work associated with completing the new access road. The project will improve access to the NBCF diversion and fish facilities; and will include a precast concrete block retaining wall, concreted rock slope protection, asphaltic concrete paving, concrete vehicle barriers, rockslope and rock block stabilization.
For the Wildcat site, the work associated with the diversion dam and conveyance system (pipeline and canal) removal was completed in 2010; which restored about 15 miles of stream habitat for Chinook salmon and Central Valley steelhead trout. Additional work was completed in October 2011 along the Wildcat Canal Access Road to correct drainage problems and install permanent erosion control measures.
A contract was awarded to Contractor Services Group, Inc in January 2013 to construct a fish barrier weir and maintain 5 cubic feet per second (cfs) minimum flow in Baldwin Creek near Asbury Diversion, downstream of the Darrah Springs State Trout Hatchery. The 5 cfs will allow for suitable salmon and steelhead habitat, while the barrier will prevent these fish, which could carry viruses, from infecting the trout hatchery. This construction is planned to be completed in December 2013 and will restore one additional mile of habitat.
Phase 1B - A contract was awarded in June 2010 and in two summer seasons the contractor has completed construction of the Inskip Powerhouse penstock bypass system and a tailrace connector on the South Fork Battle Creek near Coleman Diversion Dam. The penstock bypass system is consisted of 5,685 feet length of buried reinforced concrete pipe (RCP) and open chute and their associated appurtenance structures including a wasteway overflow, an upper jump basin, a lower jump basin, and an outlet structure; the tailrace connector is consisted of 654 feet length of 84-inch diameter RCP with a new inlet structure at the powerhouse and a gated outlet transition. In early December 2012 a significant storm event occurred causing damages to the newly constructed access roads, drainage system and erosion at the outlet structures. A government construction crew was onsite in summer 2013 to repair the access road damages and to clean the sediment deposits inside the penstock bypass upper jump basin and at the two outlets in Coleman Canal. Additional safety and facility improvements are planned for summer 2014 and 2015.
Phase 2 - Data collection, environmental compliance efforts and design works are currently underway for the remaining of the final Restoration Project phase. Construction will occur on South Fork Battle Creek and its tributaries, and is planned to occur under two construction contracts; one construction contract would involve the installation of a fish screen and ladder at Inskip diversion dam, installation of a tailrace tunnel connector from South Powerhouse to Inskip Canal, and removal of Lower Ripley Creek Feeder and Coleman diversion dams, and another construction contract would involve the removal of Soap Creek Feeder diversion and the removal of South diversion dam and appurtenant conveyance system, including the removal of South Canal. Phase 2 contract procurement is planned for 2015 and construction is anticipated to occur in 2016 and 2017.
Coleman National Fish Hatchery Adaptive Management Plan – A contract was awarded in March 2012 to Cramer Fish Sciences (CFS) for facilitation and development of a CNFH AMP. Adaptive management is needed for CNFH in order to address “scientific uncertainties” that underline aspects of Battle Creek fisheries management, including the interactions between the Battle Creek Salmon and Steelhead Restoration Project and CNFH.
A public scoping meeting was held in the Red Bluff Community Center in May 2012 to solicit public input on issues and potential remedies to be addressed in the AMP; and additional public outreach to the Tehama Board of Supervisors occurred in July 2012. An outreach meeting with commercial and recreational fishing occurred on June 27, 2013 in Sacramento.
A first internal draft of the AMP document was completed in March 2013, followed by an independent science panel review in April-May 2013. The CFS team continues to work with the Technical Advisory Committee to develop the AMP and address the Science Panel comments. A revised draft AMP is planned for public release and review in winter 2015; the final CNFH AMP is anticipated to be completed in October 2015.
