Document Description
Construction of the Red Bluff Diversion Dam (RBDD) on the Sacramento River was completed in 1964 by the U.S. Bureau of Reclamation (USBR) as part of the Sacramento Canals unit of the Central Valley Project. The dam is used by the Tehama-Colusa Canal Authority (TCCA) as the primary point of diversion for 17 water districts in Tehama, Glenn, Colusa, and Yolo Counties. Since the dam's construction, concern has been expressed regarding the dam's effect on both upstream and downstream fish migration. The dam was built with 11 movable gates. Raising the gates eliminates the dams effect and allows the river to flow unimpeded. Lowering the dam gates allows for gravity diversion into the canals and results in the creation of Lake Red Bluff. Over the years, the dam gates have been raised more frequently in an attempt to enhance fish passage. Therefore, the ability to divert irrigation water has been gradually decreased from year-round to the current 4-months (gates-in) operations from May 15th to September 14th. During the remainder of the year the dam gates are open, allowing a free flowing, unimpeded river.
