Battle Creek Restoration Project implementation includes modification of facilities at Battle Creek Hydroelectric Project diversion dam sites, located on North Fork Battle Creek, South Fork Battle Creek, and Baldwin Creek in three phases (Phases 1A, 1B and 2).
Phase 1A includes installation of fish screens and fish ladders at the North Battle Creek Feeder and Eagle Canyon diversion dams on North Fork Battle Creek; removal of Wildcat diversion dam and appurtenant conveyance system on North Fork Battle Creek; and construction of a fish barrier weir on Baldwin Creek downstream of Asbury Pumped Diversion Dam.
Phase 1B includes installation of an Inskip Powerhouse tailrace connector and bypass on South Fork Battle Creek.
Phase 2 includes installation of a fish screen and fish ladder on Inskip diversion dam; installation of a South Powerhouse tailrace connector; and removal of Lower Ripley Creek Feeder, Soap Creek Feeder, Coleman and South diversion dams and appurtenant conveyance systems, on South Fork Battle Creek.
June 2014 Status:
Phase 1A – Wildcat diversion dam and conveyance system (pipeline and canal) were removed in 2010; resulting in the restoration of about 15 miles of stream habitat for Chinook salmon and Central Valley steelhead trout. In October 2011, work occurred along the Wildcat Canal access road to correct drainage problems and to install permanent erosion control measures.
Construction of fish barrier weir, located downstream of Asbury Diversion Dam on Baldwin Creek, was completed in 2013. The barrier weir, which allows for a constant release of 5 cubic feet per second in Baldwin Creek is restoring about one mile of suitable habitat for salmon and steelhead, while protecting the upstream Darrah Springs State Trout Hatchery from infectious diseases carried by the anadromous fish.
The majority of fish screen and ladder construction has been completed at the Eagle Canyon and North Battle Creek Feeder (NBCF) diversion dams. Hydraulic evaluations of the new fish facilities, as well as physical modeling of the NBCF fish ladder and fish screen determined that modifications are necessary to improve fish screen and fish ladder passage effectiveness, while meeting PG&E canal diversion requirements. Mechanical and electrical improvements are also needed to address facility safety and operational needs. Design work is underway, and modifications are planned for implementation in 2016.
On-site construction began this month to address safety measures at the new access road to NBCF diversion dam and fish facilities. The work will include installation of a precast concrete block retaining wall; placement of concreted rock slope protection; placement of asphaltic concrete paving; installation of concrete vehicle barriers; and stabilization of the upper road cutslope rock block and the right bridge abutment excavation. Construction is anticipated to be completed in August 2014.
Phase 1B – Construction of the Inskip Powerhouse penstock bypass system and a tailrace connector on the South Fork Battle Creek near Coleman Diversion Dam was completed in 2013. The penstock bypass system consists of 5,685 feet of buried reinforced concrete pipe (RCP); an open chute; and associated appurtenance structures, including a wasteway overflow, an upper jump basin, a lower jump basin, and an outlet structure. The tailrace connector consists of 654 feet 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, which damaged the newly constructed access roads and drainage system, and created erosion at the outlet structures. In 2013, a government construction crew repaired access road damage and cleaned out the sediment deposits inside of the penstock bypass upper jump basin and at the two outlets in Coleman Canal. Additional safety and facility access improvements are planned for summer 2014 and 2015.
Phase 2 – Data collection, environmental compliance efforts and design work are underway. Construction on South Fork Battle Creek, and its tributaries, is planned to occur under two construction contracts. One construction contract would involve 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. Another construction contract would involve the removal of Soap Creek Feeder and South diversion dams and appurtenant conveyance systems, including the removal of South Canal. Phase 2 contract procurements are planned for 2016, and construction is anticipated to occur in 2017 through 2019.
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; 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 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, and the final CNFH AMP is anticipated to be completed in October 2015.
