- Nestled in the grassy hills of the western San Joaquin Valley near historic Pacheco Pass. San Luis Reservoir was constructed as a storage reservoir for the federal Central Valley Project and the California State Water Project. It stores runoff water from the Delta that would otherwise flow into the ocean. The water arrives through the California Aqueduct and the Delta-Mendota Canal, and is pumped from the O'Neil Forebay into the main reservoir during the winter and spring. The Los Banos Creek Reservoir was built to prevent storm runoff from flooding the canals.
A visitor center at the Romero Overlook provides full information on the reservoirs and water projects through audiovisual and printed materials. Telescopes are also available for viewing the area.
