The San Luis Unit, a part of the Central Valley Project and also part of the State of California Water Plan, was authorized in 1960. Reclamation and the State of California constructed and operates this unit jointly. Some features are `joint-use facilities` of the Federal Government and the State. The principal purpose of the Federal portion of the facilities is to furnish approximately 1.25 million acre-feet of water as a supplemental irrigation supply to some 600,000 acres located in the western portion of Fresno, Kings, and Merced Counties.
