Interactive graphic - click for detailed information from our brochure in PDF formatThe Red Bluff Diversion dam (RBDD), located on the Sacramento River, features a series of 11 large gates that, when lowered, form Lake Red Bluff and provide for gravity diversion of irrigation water from the sacramento River into the Tehama-Colusa and Coming Canals.  Althought the RBDD was initially operated to provide continuous diverision, the annual gates-in diversion period has be reduced over the years to less than three months to improve fish passage of several salmonid species and now green sturgeon, recently listed under the Endangered Species Act.

The construction of a screened pumping plant will improve fish passage conditions while ensuring continued water deliveries to 150,000 acres of high-value cropland.  New Features of the project will include construction of a flat-plate fish screen, intake channel, 2,500 cubic feet per second (cfs) capacity pumping plant, access bridge and discharge conduit to divert water from the Sacramento River into the Tehama-Colusa and Corning Canals.

The RBDD and the Tehama-Colusa Canal were built in the early 1960's by the Bureau of Reclamation, which owns the facilities.  The Tehama-Colusa Canal Authority operates and maintains the delivery system, providing water to its 17 member water districts throughout a four county service area, providing an economic benefit of over one billion dollars to the region annually.     More...
