Water In California
California's interconnected water system serves over 30 million people and irrigates over of farmland. As the world's largest, most productive, and potentially most controversial water system, it manages over of water per year. Water and water rights are among the state's divisive political issues. Due to the lack of reliable dry season rainfall, water is limited in the most populous U.S. state. An ongoing debate is whether the state should increase the redistribution of water to its large agricultural and urban sectors, or increase conservation and preserve the natural ecosystems of the water sources. Sources of water California's limited water supply comes from two main sources: surface water, or water that travels or gathers on the ground, like rivers, streams, and lakes; and groundwater, which is water that is pumped out from the ground. California has also begun producing a small amount of desalinated water, water that was once sea water, but has been purified. Grou ...

Water In California New
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water covers ab ...

Sustainable Groundwater Management Act
The Sustainable Groundwater Management Act (SGMA) is a three-bill package that passed the California state legislature and was signed into California state law by Governor Jerry Brown in September 2014. Its purpose is to ensure better local and regional management of groundwater use and it seeks to have a sustainable groundwater management in California by 2042. It emphasizes local management and formed groundwater sustainability agencies (GSAs) from local and regional authorities. Proposition 1 provides $100 million to financially support sustainable groundwater management as well as cleanup and storage. Background Groundwater in California is used by 85% of the population, mostly used by the agriculture industry as the main water source for crops. For years, groundwater use has been poorly managed and under-regulated to a point where the state is facing major depletion. Groundwater is particularly crucial in California because the dearth of surface water means that it ...

Southern California Coastal–Baja California
Southern California Coastal–Baja California is a freshwater ecoregion in Western North America. It covers portions of central and southern California and west of the Coast Ranges as well as most of Mexico's Baja California Peninsula, extending from the southern end of Monterey Bay to the southern tip of the Baja California Peninsula."Southern California Coastal - Baja California". Freshwater Ecoregions of the World. Accessed 14 September 2021/ref> Geography The rivers and streams are mostly short and not very large, and run from origins in the mountains to the sea. The climate ranges from semi-humid to arid, and rainfall is highly seasonal and can be irregular, so many streams have big seasonal variations in flow, or are intermittent. The ecoregion has an area of . 76% of the ecoregion is in Mexico's states of Baja California and Baja California Sur, and 24% is in California. Elevations range from sea level to over 3300 meters. The ecoregion includes the western slope of the S ...

South Lahontan
The South Lahonton hydrologic region encompasses several interior basins east of the Sierra Nevada and the Transverse Ranges, with an area of . It covers the western portion of the Mojave Desert and a southwestern portion of the Great Basin desert, and extends into the forests of the southeastern Sierra Nevada and the montane chaparral and woodlands of the northeastern Transverse ranges. The ecoregion has an arid to semi-arid climate, with average annual rainfall of . The region is closed or endorheic, and none of its rivers or streams reach the sea. They instead empty into lake beds from which the water evaporates, leaving deposits of salts and other minerals. There are some year-round mountain streams and springs, but most the large rivers are intermittent, and the lakes vary in extent based on variations in rainfall and runoff. Perennial streams include the Owens River and tributaries to Mono Lake, such as Rush Creek and Lee Vining Creek. Drainage basins include the Antel ...

San Joaquin River
The San Joaquin River (; es, Río San Joaquín) is the longest river of Central California. The long river starts in the high Sierra Nevada, and flows through the rich agricultural region of the northern San Joaquin Valley before reaching Suisun Bay, San Francisco Bay, and the Pacific Ocean. An important source of irrigation water as well as a wildlife corridor, the San Joaquin is among the most heavily dammed and diverted of California's rivers. People have inhabited the San Joaquin Valley for more than 8,000 years, and it was long one of the major population centers of pre-Columbian California. Starting in the late 18th century, successive waves of explorers then settlers, mainly Spanish and American, emigrated to the San Joaquin basin. When Spain colonized the area, they sent soldiers from Mexico, who were usually of mixed native Mexican and Spanish birth, led by Spanish officers. Franciscan missionaries from Spain came with the expeditions to evangelize the natives by teac ...

San Francisco Bay
San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the big cities of San Francisco, San Jose, and Oakland. San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Wetland of International Importance on February 2, 2017. Size The bay covers somewhere between , depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. The main part of the bay meas ...

North Lahontan
Lake Lahontan was a large endorheic Pleistocene lake of modern northwestern Nevada that extended into northeastern California and southern Oregon. The area of the former lake is a large portion of the Great Basin that borders the Sacramento River watershed to the west. The lake was named by Clarence King during the Geological Exploration of the Fortieth Parallel. The name honors Louis-Armand de Lom d'Arce de Lahontan, Baron de Lahontan, a French soldier and explorer. History At its peak approximately 12,700 years ago (during a period known as the Sehoo Highstand), the lake had a surface area of over , with its largest component centered at the location of the present Carson Sink. The depth of the lake was about at present day Pyramid Lake, and at the Black Rock Desert. Lake Lahontan, during this most recent glacial period, would have been one of the largest lakes in North America. Climate change around the end of the Pleistocene epoch led to a gradual desiccation of ...

Sacramento River
The Sacramento River ( es, Río Sacramento) is the principal river of Northern California in the United States and is the largest river in California. Rising in the Klamath Mountains, the river flows south for before reaching the Sacramento–San Joaquin River Delta and San Francisco Bay. The river drains about in 19 California counties, mostly within the fertile agricultural region bounded by the California Coast Ranges, Coast Ranges and Sierra Nevada (U.S.), Sierra Nevada known as the Sacramento Valley, but also extending as far as the volcanic plateaus of Northeastern California. Historically, its watershed has reached as far north as south-central Oregon where the now, primarily, endorheic basin, endorheic (closed) Goose Lake (Oregon-California), Goose Lake rarely experiences southerly outflow into the Pit River, the most northerly tributary of the Sacramento. The Sacramento and its wide natural floodplain were once abundant in fish and other aquatic creatures, notably one ...

North Coast (California)
The North Coast of California (also called the Redwood Empire or the Redwood Coast in reference to the dense redwood forests throughout the region) is a region in Northern California that lies on the Pacific coast between San Francisco Bay and the Oregon border. It commonly includes Mendocino, Humboldt, and Del Norte counties and sometimes includes two counties from the San Francisco Bay area, Marin and Sonoma. Cities Much of the area is rural, and it contains few major cities. The only city with a population of over 100,000 is Santa Rosa (population 178,000) in Sonoma County, which is the largest city of the North Coast under the five-county definition. Eureka (population 27,000) in Humboldt County is the largest under the three-county definition. Despite their relatively smaller size to the major cities elsewhere in the state, many of the region's cities and towns have historical importance to the state or regional importance.
