San Luis Reservoir SRA

State Recreation Area

“ The Basalt Campground will be closed from September 10th , 2009 until May 30th, 2010 due to a major water and sewer plant upgrade project. Campers will be able to utilize the nearby San Luis Creek Campground and the Medeiros Area Campground during this time period. The Basalt launch ramp will remain open. The Department apologizes for any Inconvenience that this closure may cause to our visitors.”

Nestled in the grassy hills of the western San Joaquin Valley near historic Pacheco Pass, San Luis Reservoir State Recreation Area is noted for boating, board sailing, camping, and picnicking. But it’s anglers who find the unit’s three lakes most inviting.

The area around San Luis Reservoir and O'Neill Forebay is often very windy, and winds can come up quite suddenly. Watch the wind warning lights at the Basalt entrance station, Quien Sabe Point, and Romero Visitor Center. On the forebay, wind warning lights are located at the Medeiros boat ramp and above the South Beach picnic area at San Luis Creek.

Climate/recommended clothing: Summer temperatures here average in the mid-90s and occasionally exceed 100° but evenings are usually cool and pleasant. Rainfall averages eight to nine inches a year, mostly between November and April. In winter, temperatures seldom go below freezing, and tule fogs are frequent. In the spring, the golden-brown hills are coated with a fleeting green, highlighted by bursts of wildflowers colors.

About the Park
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 audio-visual and printed materials. Telescopes are also available for viewing the area. The Romero Visitor Center is administered by the CA Dept. of Water Resources.

Long before the dams and canals were built, this land was the home of the Northern Valley Yokuts, native Americans who harvested seeds, acorns, and the roots of the tules that grew in the marshes of the sluggish San Joaquin River. There were also fish, geese, and ducks for food, as well as huge herds of pronghorn antelope and tule elk on the plains. With the coming of the Spanish, though, this way of life disappeared. Many of the valley people were taken to missions around 1805, and an epidemic, possibly of malaria, decimated the human population of this area in 1833. In the 1850s, the survivors were killed or driven off by Euroamerican settlers.

Pacheco pass was named for Don Juan Pacheco, who settled here in the 1840s. The pass was used by Native Americans, Spanish soldiers and missionaries, Mexican ranchers, and gold miners, as well as more recent travelers. In 1856, Andrew Firebaugh improved the pass and made it a toll road, with a toll house two miles west of the summit. He had hardly finished when the Butterfieid-Overland stages began using the road as part of their route from San Francisco to Missouri.

The first water works in the area were constructed in 1871, when farmers built a canal from Mendota Dam to Los Banos Creek to irrigate their wheat crops. Many canals were added over the years, until they totaled 180 miles in length. Ground was broken in 1962 for the San Luis Project, which created the current reservoirs. Today, Los Banos area farmers cultivate alfalfa, grapes, tomatoes, melons, corn, cotton, beans, sugar beets, fruits, nuts, and raise dairy and beef cattle.

Camping
San Luis Reservoir State Recreation Area has four campgrounds: Basalt, San Luis Creek, Medeiros, and Los Banos Creek. All campgrounds are open year round.

Basalt Campground

The Basalt Campground will be closed from September 10^th , 2009 until May 30^th, 2010 due to a major water and sewer plant upgrade project.

Alternate camping nearby with improved accessible features is available at the San Luis Creek Area located approximately 7 miles away and accessed via the San Luis Creek area entrance from HWY 152.

The only campground located near San Luis Reservoir, Basalt has 79 developed family campsites in a shaded, wind-protected valley. Some sites will accommodate trailers and motor homes up to about 40 feet. Each site has a fire ring and table with water faucets nearby. New restroom facilities offer hot pay showers and flushable toiletes. A dump station is available to registered campers. Reservations can be made year round.

The campground has very little shade and is in an open area susceptible to wind. No flush toilets or showers are available. Each site has a level pad, fire ring, and a table. Some sites will accommodate trailers and motor homes up to about 38 feet. A new 5 mile accessible walking trail follows the O’Neill Forebay shoreline and connects the campground to the North Beach day-use area. A dump station is available for registered campers. All boats must be removed from the water by sunset. Reservations can be made year round.
