|Country||United States of America|
The San Joaquin Valley / / is the area of the Central Valley of the U.S. state of California that lies south of the Sacramento–San Joaquin River Delta. Eight counties comprise the San Joaquin Valley: all of Kings County; a majority of Fresno, Kern, Merced, and Stanislaus counties; and segments of Madera, San Luis Obispo, and Tulare counties. Although a majority of the valley is rural, it does contain urban cities such as Fresno, Bakersfield, Stockton, Modesto, Turlock, Visalia, Porterville, Merced, and Hanford.

The San Joaquin Valley extends from the Sacramento–San Joaquin River Delta in the north to the Tehachapi Mountains in the south, and from the various California coastal ranges (from the Diablo Range in the north to the Temblor Range in the south) in the west to the Sierra Nevada in the east. Unlike the Sacramento Valley, the river system for which the San Joaquin Valley is named does not extend very far along the valley. Most of the valley south of Fresno, instead, drains into Tulare Lake, which no longer exists continuously due to diversion of its sources. The valley's primary river is the San Joaquin, which drains north through about half of the valley into the Sacramento–San Joaquin River Delta. The Kings and Kern Rivers are in the southern endorheic basin of the valley, all of which have been largely diverted for agricultural uses and are mostly dry in their lower reaches.
The San Joaquin Valley began to form about 66 million years ago during the early Paleocene era. Broad fluctuations in the sea level caused various areas of the valley to be flooded with ocean water for the next 60 million years. About 5 million years ago, the marine outlets began to close due to uplift of the coastal ranges and the deposition of sediment in the valley. Starting 2 million years ago, a series of glacial episodes periodically caused much of the valley to become a fresh water lake. Lake Corcoran was the last widespread lake to fill the valley about 700,000 years ago. At the beginning of the Holocene there were three major lakes remaining in the southern part of the Valley, Tulare Lake, Buena Vista Lake and Kern Lake. In the late 19th and in the 20th Century, agricultural diversion of the Kern River eventually dried out these lakes. Today, only a fragment of Buena Vista Lake remains as two small lakes Lake Webb and Lake Evans in a portion of the former Buena Vista Lakebed.
The San Joaquin Valley has hot, dry summers and has historically enjoyed cool rainy winters characterized by dense tule fog. Its rainy season normally runs from November through April, but since 2011 when a drought became evident it generally receives minimal to no rain at all. The drought was still extant by mid-August 2014 with scientists saying it would likely continue indefinitely, for anywhere from several years to several decades to come.
The National Weather Service Forecast Office for the San Joaquin Valley is located in Hanford and includes a Doppler weather radar. Weather forecasts and climatological information for the San Joaquin Valley are available from its official website.
The total population of the eight counties comprising the San Joaquin Valley at the time of the 2010 U.S. Census was 3,971,659.
By some estimates, federal restrictions on shallow well irrigation systems threaten the productivity of the San Joaquin Valley, which produces the majority of the 12.8% of the United States' agricultural production (as measured by dollar value) that comes from California. Grapes—table, raisin, and to a lesser extent wine—are perhaps the valley's highest-profile product, but equally (if not more) important are cotton, nuts (especially almonds and pistachios), citrus, and vegetables. Though it has been called "The food basket of the World", the San Joaquin Valley has not been nationally recognized for the diversity of its produce. Oranges, peaches, garlic, tangerines, tomatoes, kiwis, hay, alfalfa and numerous other crops have been harvested with great success. The J. G. Boswell Company's farming operation in Kings County is the largest single cotton farm in the world, occupying over 162 square kilometres (40,000 acres). Certain places are identified quite strongly with a given crop: Stockton produces the majority of the domestic asparagus consumed in the United States, and Fresno is the largest producer of raisins, originally a Middle Eastern commodity.
Cattle and sheep ranching are also vitally important to the valley's economy. During the late 19th century and early 20th century, the Miller & Lux corporation built an agricultural monopoly centered around cattle. The corporation can be characterized as a precursor to corporate farming transforming the yeoman farmer into wage workers. The success of the business can be attributed to his direct management style which is reflected in his detailed correspondences to his subordinates. During recent years, dairy farming has greatly expanded in importance. As areas such as Chino and Corona have become absorbed into the suburban sprawl of Los Angeles, many dairy farmers have cashed out and moved their herds to Kings, Tulare, and Kern counties.
Between 1990 and 2004, 28,092 hectares (70,231 acres) of agricultural land was lost to urban development in the San Joaquin Valley. Although there have been some token efforts at confronting the problems of (sub)urban sprawl, the politically Conservative climate of the Valley generally prefers traditional suburban sprawl type of growth such as low density housing and strip malls anchored by so-called big box stores and opposes measures such as "Smart Growth", "Transit Oriented Development", "High Density Housing", and increased public transit such as light and commuter rail. By August 2014, a three year drought was prompting changes to the agriculture industry in the valley. Farmers began using complex irrigation systems and using treated waste water to feed crops, while many were switching from farming cotton to other commodities, chief among them, almonds.
California has long been one of the nation's most important oil-producing states, and the San Joaquin Valley has long since eclipsed the Los Angeles Basin as the state's primary oil production region. Scattered oil wells on small oil fields are found throughout the region, and several enormous extraction facilities – most notably near Lost Hills and Taft, including the enormous Midway-Sunset Oil Field, the third-largest oil field in the United States – are veritable forests of pumps.
Shell operated a major refinery in Bakersfield; it was sold in 2005 to Flying J, a Salt Lake-based firm that operates truck stops and refineries. Flying J's bankruptcy in 2009 resulted in the refinery being shut down.
The oil and gas fields in Kern County are receiving increased attention since the July 2009 announcement by Occidental Petroleum of significant discovery of oil and gas reserves Even prior to this discovery the region retains more oil reserves than any other part of California. Of California fields outside of the San Joaquin Valley, only the Wilmington Oil Field in Los Angeles County has untapped reserves greater than 100,000,000 barrels (16,000,000 m3), while six fields in the San Joaquin Valley (Midway-Sunset, Kern River, South Belridge, Elk Hills, Cymric, and Lost Hills) each have reserves exceeeding 100,000,000 barrels (16,000,000 m3) of oil.
Other major industries and employers
The isolation and vastness of the San Joaquin Valley, as well as its poverty and need for jobs, have led the state to build numerous prisons in the area. The most notable of these is Corcoran, whose inmates include Charles Manson and Juan Corona. Other correctional facilities in the valley are at Avenal, Chowchilla, Tracy, Delano, Coalinga, and Wasco.
The only significant military base in the region is Naval Air Station Lemoore, a vast air base located 25 kilometres (16 mi) WSW of Hanford. Unlike many of California's other military installations, NAS Lemoore's operational importance has increased in the 1990s and 2000s. The other, Castle Air Force Base, located near Atwater was closed during the Base Realignment and Closure of the 1990s. Although both are in Kern County, Edwards Air Force Base and China Lake Naval Air Weapons Station are located in the High Desert area of that county.
The United States Census Bureau issued a report entitled the American Community Survey in 2007, which found that six San Joaquin Valley counties had the highest percentage of residents living below the federal poverty line in 2006 of any counties in California. The report also revealed that the same six counties were among the 52 counties with the highest poverty rate in the United States. In most Valley cities crime rates such as burglary, theft, and assault tend to be significantly higher than the national averages.
The San Joaquin Valley has been a major influence in American country music, particularly through the "Bakersfield sound". The Valley has been the home to many country music singers such as Buck Owens, Merle Haggard, Billy Mize, Red Simpson, The Maddox Brothers and Rose and the Sons of the San Joaquin. The Valley also has a strong literary tradition, heavy in poetry, producing many famous poets such as Gary Soto, current California Poet Laureate Juan Felipe Herrera, David St. John and Burlee Vang. An MFA Creative Writing program started by former US Poet Laureate Philip Levine, resides at Fresno State, continuing to cultivate the region's literary talent.

Ethnic and cultural groups
While the barrios of East Los Angeles are California's most famous areas dominated by persons of Mexican ancestry, both first-generation Mexican immigrants and well-established Chicanos are important populations in the San Joaquin Valley. Since the onset of the bracero program during World War II, virtually all of the agricultural workers in the region have been of Mexican ancestry. Ethnic and economic friction between Mexican-Americans and the valley's predominantly white farming elite manifested itself most notably during the 1960s and 1970s, when the United Farm Workers, led by César Chávez, went on numerous strikes and called for boycotts of table grapes. The UFW generated enormous sympathy throughout the United States, even managing to terminate several agricultural mechanization projects at the United States Department of Agriculture. However, from the 1970s onward, landlords and large corporations have also hired illegal immigrants, because of the ability to work long hours for low pay due to no income tax on undocumented salaries.
European and Asian groups
The San Joaquin Valley has—by California standards—an unusually large number of European, Middle Eastern, and Asian ethnicities in the heritage of its citizens. These communities are often quite large and, relative to Americans immigration patterns, quite eclectic: for example, there are more Azorean Portuguese in the San Joaquin Valley than in the Azores. Many groups are found in majorities in specific cities, and hardly anywhere else in the region. For example, Assyrians are concentrated in Turlock, Dutch in Ripon, Sikhs in Stockton and Livingston, and Yugoslavs in Delano. Kingsburg is famous for its distinctly Swedish air, having been founded by immigrants from that country. Ethnic groups found in a broader area are Portuguese, Armenians, Basques, and the "Okies" who migrated to California from the Midwest and South. Since the early 1970s East Indians of predominantly Punjabi, Gujrati and Southern India have settled in the valley communities. Most recently large numbers of Pakistanis have settled in Modesto and Lodi. In addition, the late 1970s and 80s saw an influx of immigrants from Indochina following the War in Vietnam. These immigrants, the majority of whom are Hmong, Laotian, Cambodian, and Vietnamese, have settled in the communities of Stockton, Modesto, Merced, and Fresno.
The Filipino American population is concentrated in Delano and Lathrop. Filipinos have a strong history in Stockton. Filipino organizations in Stockton are reflected in various commercial buildings identified as Filipino. Filipinos fought for the U.S. against Japan in WWII, in exchange for favorable immigration status. Stockton has been an adjunct to the San Francisco Bay Area, which was a major military production and transit area during WWII. Filipino emigration to Stockton followed.
These cultures are often the result of established ethnic communities and groups of immigrants coming to the United States at once. This is in part due to the founding of religious communes in the San Joaquin Valley: for example, the first permanent Sikh Gurdwara was founded in Stockton in 1915. These cultures are very different and unique.
Colonel Allensworth State Historic Park marks the location of the only California town to be founded, financed and governed by African Americans. The small farming community was founded in 1908 by Lt. Colonel Allen Allensworth, Professor William Payne, William Peck, a minister, John W. Palmer, a miner, and Harry A. Mitchell, a real estate agent, dedicated to improving the economic and social status of African Americans. Uncontrollable circumstances, including a drop in the area's water table, resulted in the town's demise. The "Allensworth Historic District" is listed on the National Register of Historic Places. The park is in Allensworth, California, an unincorporated area in Tulare County, California, United States.
Okies and Arkies
The Depression-era migrants to the San Joaquin Valley from the South and Midwest are one of the more well-known groups in the Central Valley, in large part due to the popularity of John Steinbeck's novel The Grapes of Wrath and the Henry Fonda movie made from it. By 1910, agriculture in the southern Great Plains had become nearly unviable due to soil erosion and poor rainfall. Much of the rural population of states such as Kansas, Texas, Oklahoma, and Arkansas left at this time, selling their land and moving to Chicago, Kansas City, Detroit, and fast-growing Los Angeles. Those who remained experienced continuing deterioration of conditions, which reached their nadir during the drought that began in the late 1920s and created the infamous Dust Bowl. (Small cotton farmers in states such as Mississippi and Alabama suffered similar problems from the first major infestation of the boll weevil.) When the onset of the Great Depression created a national banking crisis, family farmers—usually heavily in debt—often had their mortgages foreclosed by banks desperate to shore up their balance sheets. In response, many farmers loaded their families and portable possessions into their automobiles and drove west.
Taking Route 66 to Barstow or Los Angeles and crossing the Tehachapi or Tejon passes, they began new lives as fruit and vegetable pickers on truck farms in the San Joaquin Valley. Having gone from the relative independence of homesteading to a condition that was essentially peasantry, many of them lived in squalid agricultural camps and were deeply unhappy with their economic plight; domestic disputes, crime, and suicide were rampant, and occasional riots broke out. New Deal measures alleviated some of these problems, albeit belatedly: by the time that The Grapes of Wrath drew public attention to the Okies' plight, many of them had already left the valley. Those who didn't were assimilated into California culture and society where they and their descendants became noted tradesmen, educators, legislators and professional business people.
Many of the Okies and Arkies left the San Joaquin Valley during World War II, most of them going to Los Angeles, San Francisco and San Diego to work in war industries. Many of those who stayed ended up in Bakersfield and Oildale, as the southern San Joaquin Valley became an important area of oil production after major Southern California oil fields such as Signal Hill began to dry up. Their influence remains strong: Bakersfield resembles a West Texas town such as Odessa or Lubbock far more than it resembles anywhere else in California. Country music legends Buck Owens and Merle Haggard came out of Bakersfield's honky-tonk scene and created a hard-driving sound that is still deeply associated with the city.
The California real estate boom that began in the late 1990s has significantly changed the San Joaquin Valley. Once distinctly and fiercely independent of Los Angeles and San Francisco, the area has seen increasing exurban development as the cost of living forces young families and small businesses further and further away from the coastal urban cores. Stockton, Modesto, Tracy, Manteca, and Los Banos are increasingly dominated by commuters to San Francisco and Silicon Valley, and the small farming towns to the south are finding themselves in the Bay Area's orbit as well. Bakersfield, traditionally a boom-bust oil town once described by urban scholar Joel Kotkin as an "American Abu Dhabi," has seen a massive influx of former Los Angeles business owners and commuters, to the extent that gated communities containing million-dollar homes are going up on the city's outskirts. Wal-Mart, IKEA, Target and various large shipping firms have built huge distribution centers at the far southern end of the valley, lured by the convenience of Route 58 and the region's low wages. Further integration with the rest of the state is likely to continue for the foreseeable future.

Interstate 5 (I-5) and State Route 99 (SR 99, or just "99") each run along for almost the entire length of the San Joaquin Valley. I-5 runs in the western part of the valley, bypassing the major population centers (including Fresno, currently the largest U.S. city without an Interstate highway), while 99 runs through them. Both highways then merge at the southern end of valley en route to Los Angeles. When the Interstate Highway System was created in the 1950s, the decision was made to build I-5 as an entirely then-new freeway bypass instead of upgrading the then-existing U.S. 99. Since then, state and federal representatives have pushed to convert 99 to an Interstate, although this cannot occur until all of the portions of 99 between I-5 and the U.S. 50 junction in Sacramento are upgraded to freeway standards.
State Route 58 (SR 58), which is a freeway in Bakersfield and along most of its route until its terminus in Barstow, is an extremely important and very heavily traveled route for truckers from the valley and the Bay Area who want to cross the Sierra Nevada and leave California (by way of Interstate 15 or Interstate 40) without having to climb Donner Pass or brave the traffic congestion of Los Angeles. Proposals have also been made to designate this highway as a western extension of I-40 once the entirety of the route between Mojave and Barstow has been upgraded to a freeway. This would provide an Interstate connection for Bakersfield, currently the second-largest U.S. city without an Interstate. The most recent additions to this system are State Highway 168 and 180. Route 168 begins at Fresno on Route 180 linking to Huntington Lake in the mountains through Clovis and many smaller communities. This route is part of the California Freeway and Expressway System and is eligible for the State Scenic Highway System. State Route 180 is a state highway in California, United States, which runs through the heart of the San Joaquin Valley from Mendota through Fresno to Kings Canyon National Park. A short piece near the eastern end, through the Grant Grove section of Kings Canyon National Park, is not state-maintained. The part east of unbuilt State Route 65 near Minkler is eligible for the State Scenic Highway System; the road east of Dunlap is the Kings Canyon Scenic Byway, a Forest Service Byway.
Other important highways in the valley include State Route 46 (SR 46) and State Route 41 (SR 41), which respectively link the California Central Coast with Bakersfield and Fresno; State Route 33, which runs south to north along the valley's western rim and provides a connection to Ventura and Santa Barbara over the Santa Ynez Mountains; and State Route 152 (SR 152), an important commuter route linking Silicon Valley with its fast-growing exurbs such as Los Banos.
Amtrak provides rail service through the San Joaquin Valley. There are also plans for a high-speed rail line that will link the valley with San Francisco, Los Angeles, Sacramento, and San Diego. While many valley politicians and businesses are eager supporters of the line, eager to provide better connections to the larger and wealthier cities to the north and south, factions in cities such as Modesto and Stockton have opposed the line due to adverse impacts such as increased noise. Even if the project were to be approved, construction would probably not begin until 2013 at the earliest.
A now large port for oceangoing cargo ships is present in Stockton, which is connected to the San Francisco Bay by way of a deepwater channel along the San Joaquin River Delta. Congestion at the Port of Los Angeles and the Port of Long Beach, which together account for the majority of container traffic in the United States, has led to calls for further development of the port.
Unlike the Sacramento River, the San Joaquin River has never been navigable much past Stockton. This was a significant factor in the San Joaquin Valley's slow 19th-century development.
Hemmed in by mountains and rarely having strong winds to disperse smog, the San Joaquin Valley has long suffered from some of the United States' worst air pollution. This pollution, exacerbated by stagnant weather, comes mainly from diesel and gasoline fueled vehicles and agricultural operations. Population growth has caused the San Joaquin Valley to rank with Los Angeles and Houston in most measures of air pollution. Only the Inland Empire region east of Los Angeles has worse overall air quality, and the San Joaquin Valley led the nation in 2004 in the number of days with quantities of ozone considered unhealthy by the Environmental Protection Agency. Although industrial activity, as well as driving, occurs year-round, the air pollution is worse in the winter.
Groundwater purity is an ongoing issue in this valley including the Turlock Basin. San Joaquin County has better air quality than any other region in the San Joaquin Valley, while the Sacramento region and Stanislaus County have the worst.
Less water is due to Federal restrictions on shallow water irrigation which results in concentrated Water pollution. Air pollution is not properly diluted with adequate water supply. Lack of adequate irrigation presents another significant challenge to food production capability in the valley. Because of federal restrictions on irrigation, Soil salination is no longer diluted with adequate moisture in fertile areas. Reduced irrigation has significantly reduced the viability of some of the valley's most fertile tracts, especially those in the Tulare lake bed.
San Joaquin Valley Fever is one common term for coccidioidomycosis, a fungal infection caused by Coccidioides immitis through the inhalation of airborne dust or dirt. The valley is just one of the areas in the southwestern United States where the illness is endemic due to C. immitis residing in the soil.
