In ecology, an oasis is a fertile area of a desert or semi-desert environment that sustains plant life and provides habitat for animals. Surface water and land may be present, or water may only be accessible from wells or underground channels created by humans. In geography, an oasis may be a current or past rest stop on a transportation route, or less-than-verdant location that nonetheless provides access to underground water through deep wells created and maintained by humans.
The Mojave Desert is a desert in the rain shadow of the southern Sierra Nevada mountains and Transverse Ranges in the Southwestern United States. Named for the indigenous Mohave people, it is located primarily in southeastern California and southwestern Nevada, with small portions extending into Arizona and Utah.
The Mojave River is an intermittent river in the eastern San Bernardino Mountains and the Mojave Desert in San Bernardino County, California, United States. Most of its flow is underground, while its surface channels remain dry most of the time, except for the headwaters and several bedrock gorges in the lower reaches.
Owens Valley is an arid valley of the Owens River in eastern California in the United States. It is located to the east of the Sierra Nevada, west of the White Mountains and Inyo Mountains, and is within the northern end of the Mojave Desert. It sits on the west edge of the Great Basin. The mountain peaks on the West side reach above 14,000 feet (4,300 m) in elevation, while the floor of the Owens Valley is about 4,000 feet (1,200 m), making the valley the deepest in the United States. The Sierra Nevada casts the valley in a rain shadow, which makes Owens Valley "the Land of Little Rain". The bed of Owens Lake, now a predominantly dry endorheic alkali flat, sits on the southern end of the valley.
The Antelope Valley is located in northern Los Angeles County, California, United States, and the southeast portion of California's Kern County, and constitutes the western tip of the Mojave Desert. It is situated between the Tehachapi, Sierra Pelona, and the San Gabriel Mountains. The valley was named for the pronghorns that roamed there until they were all eliminated in the 1880s, mostly by hunting, or resettled in other areas. The principal cities in the Antelope Valley are Palmdale and Lancaster.
The Governor Edmund G. Brown California Aqueduct is a system of canals, tunnels, and pipelines that conveys water collected from the Sierra Nevada Mountains and valleys of Northern and Central California to Southern California. Named after California Governor Edmund Gerald "Pat" Brown Sr., the over 400-mile (640 km) aqueduct is the principal feature of the California State Water Project.
The Amargosa River is an intermittent waterway, 185 miles (298 km) long, in southern Nevada and eastern California in the United States. It drains a high desert region, the Amargosa Valley in the Amargosa Desert northwest of Las Vegas, into the Mojave Desert, and finally into Death Valley where it disappears into the ground aquifer. Except for a small portion of its route in the Amargosa Canyon in California and a small portion at Beatty, Nevada, the river flows above ground only after a rare rainstorm washes the region. A 26-mile (42 km) stretch of the river between Shoshone and Dumont Dunes is protected as a National Wild and Scenic River. At the south end of Tecopa Valley the Amargosa River Natural Area protects the habitat.
The Mokelumne River is a 95-mile (153 km)-long river in northern California in the United States. The river flows west from a rugged portion of the central Sierra Nevada into the Central Valley and ultimately the Sacramento–San Joaquin River Delta, where it empties into the San Joaquin River-Stockton Deepwater Shipping Channel. Together with its main tributary, the Cosumnes River, the Mokelumne drains 2,143 square miles (5,550 km2) in parts of five California counties. Measured to its farthest source at the head of the North Fork, the river stretches for 157 miles (253 km).
Cadiz is an unincorporated community in the Mojave Desert in San Bernardino County, California, United States. It is located just south of the Marble Mountains near the National Trails Highway. Cadiz was a water stop on the railroad.
Newberry Springs is an unincorporated community in the western Mojave Desert of Southern California, located at the foot of the Newberry Mountains in San Bernardino County, California, United States. Newberry Spring is a spring that in the 19th century supplied water to the local Santa Fe Railway and originally was a camping place. The population at the 2000 census was 2,895.
The Big Morongo Canyon Preserve is a 31,000-acres (130 km2) native plants habitat and wildlife preserve located in the Little San Bernardino Mountains of the Transverse Ranges, in the transition zone between the higher Mojave Desert and lower elevation Colorado Desert section of the Sonoran Desert. Due to its location within this transition zone, the area is especially high in natural diversity. The natural spring fed desert oasis found here is one of the 10 largest Cottonwood and Willow riparian habitats in California. It is also identified by the Audubon Society as one of the most important avian habitat areas in California.
Lake Perris is an artificial lake completed in 1973. It is the southern terminus of the California State Water Project, situated in a mountain-rimmed valley between Moreno Valley and Perris, in what is now the Lake Perris State Recreation Area. The park offers a variety of recreational activities. Because of this and the lake's proximity to major population centers, it is very crowded during the summer months.
Harper Lake is a dry lake located in the Mojave Desert near the small community of Lockhart, California, in northwestern San Bernardino County of Southern California. The lake is accessible from Harper Lake Road, which runs north off of State Route 58 midway between Boron and Barstow.
California's interconnected water system serves almost 40 million people and irrigates over 5,680,000 acres (2,300,000 ha) of farmland. As the world's largest, most productive, and potentially most controversial water system, it manages over 40 million acre-feet (49 km3) of water per year. Use of available water averages 50% environmental, 40% agricultural and 10% urban, though this varies considerably by region and between wet and dry years. In wet years, "environmental" water averages 61%, while in dry years it averages 41%, and can be even lower in critically dry years.

Antelope Valley Conservancy is a public-benefit corporation that preserves natural habitats and watershed resources. It was founded 2005, granted 501(c)(3) and 170(b)(1)(a)(vi) tax status in 2006, absorbed the Antelope Valley Trails Recreation and Environmental Council (AVTREC) in 2007, and earned authorization from the California Department of Fish and Game to hold mitigation lands in 2008.
The Coachella Valley Water District is an independent special district formed in 1918, specifically to protect and conserve local water sources in the Coachella Valley. Since then, the district has grown into a multi-faceted agency that delivers irrigation and domestic (drinking) water, collects and recycles wastewater, provides regional storm water protection, replenishes the groundwater basin and promotes water conservation.
Mojave Trails National Monument is a large U.S. National Monument located in the state of California between Interstates 15 and 40. It partially surrounds the Mojave National Preserve. It was designated by President Barack Obama on February 12, 2016, along with Castle Mountains National Monument and Sand to Snow National Monument, also in southern California. It is under the administration of the Bureau of Land Management.
Sand to Snow National Monument is a U.S. National Monument located in San Bernardino County and northern Riverside County, Southern California.
Borrego Valley Groundwater Basin, located in the very southern region of California, is one of the driest basins in the state. With climate change predicted to have strong effects into foreseeable future, the region is viewed with a skepticism in the sustainable use of water at current rates of consumption. Both natural and man-made geographic divisions within this basin allow for a closer inspection of the various management techniques implemented throughout the years, and provide a basis for what may be pursued for an uncertain future.
