The mission of the Bay-Delta Office (BDO) is to plan facilities and implement actions in the Sacramento-San Joaquin Delta to improve water quality, water supply and reliability, and the ecosystem. The Office develops and maintains computer simulation models to analyze the effects of projects and actions proposed or undertaken by the Department or other agencies.

2-Gates Fish Protection Demonstration Project

This proposed demonstration project led by the US Bureau of Reclamation would install and operate removable gate structures at two key Delta locations to test the ability of the structures to improve protection for delta smelt and other sensitive aquatic species. In a five-year pilot study, the gates would control flows in selected interior Delta channels to evaluate whether these changes reduce entrainment of fish into pumps and improve water supplies to the California's State Water Project and the Federal Central Valley Project.
