San Joaquin County, whose seat is Stockton, is the northern most county in the Valley that bears its name. With the Sacramento Valley, the two form the Great Valley, which is one-tenth the land mass of California. French fur trappers worked the rich land of the San Joaquin Valley for nearly 20 years before the first American immigrants crossed the Sierras in 1841.

Each of the county's cities and towns had beginnings that included a segment of settlers from far corners of the world. Lodi, for example, was settled by German emigrants, and Ripon became home to many pioneers from Holland. At one time, Stockton housed the largest population of Chinese in California.

San Joaquin County continues to reflect a global likeness, not only by its diverse population. but also by its many commercial and agricultural ventures and its ability to market items to anywhere in the world.

In 1869, fortune rode into the county on rails with the arrival of the Central Pacific Railroad. Soon, new towns began to spring up around train stations in Lodi, Lathrop, Tracy, Manteca, Ripon and San Joaquin County.

The county is probably most famous for its prime agricultural land, its diverse topography and its climate. Agriculture and related businesses are regarded the greatest assets in the county's economy. Cattle ranches were the first industry in the Valley, and fields of grain and alfalfa were planted to support the livestock. Dairy farms followed.

San Joaquin County boasts an inland seaport in Stockton and more than a thousand miles of recreational waterways along the Delta. During the last three decades of the 19th century, the county became the bread basket of the world. River boats carried grain and other goods from the Stockton waterfront to San Francisco and points beyond. And during the 1920s, the Stockton Channel was widened and dredged deep enough to allow ocean-going vessels to sail into the port of Stockton.

Today the county is still regarded as a prime location for getting goods where they need to go. Sharpe Army Depot in Lathrop has become the Defense Distribution Region West (DDRW), accounting for S77. 4 million in salaries in the region. And in 1994, the Union Pacific railroad opened its largest truck-to-train transfer station adjacent to the DDRW facility, making San Joaquin County a major competitor in transporting agricultural commodities and goods. Union Pacific officials expect that its terminal business will grow by more than 10 percent a year. San Joaquin County is in California's central valley, 93 miles east of San Francisco and 45 miles south of Sacramento. The County population is 673,000. Strategically located in Northern California's dynamic growth corridor, San Joaquin County is home to major agri-business, manufacturing and distribution companies. These include Diamond of California, General Mills, Fairmont Sign Company, Dana Corporation, Fox River Paper Company, Mondavi Woodbridge Winery, Nestle and Yellow Freight. San Joaquin County boasts eleven cities and some of the finest opportunities in the state for boating, fishing, camping, history-gathering, or just plain fun in the sun. The county is one of the most agriculturally rich regions in California and is the number one producer, statewide, of asparagus. Twenty-four thousand acres of county farmland is dedicated to production of this crop

    Valley Fog: Winter in the San Joaquin Valley means the onset of Tule Fog. So far this season we have had several days of very dense fog. Radiation Fog, or Tule Fog as it is known in the Central Valley, develops on clear nights with light wind when the ground is moist. At night, the ground cools rapidly, which in turn cools the air near the surface. As the air cools, the moisture is condensed into tiny water droplets and fog is formed. As this process continues, the depth of the fog layer gradually increases and becomes more dense, often reducing visibility to one-quarter mile or less. The long nights of late fall and winter are ideal for this type of fog development.

History:San Joaquin County History • Ghost Towns • Historical Society • Lincoln Highway Through San Joaquin County • Lincoln Highway Two

In 1808, Spanish Army Lieutenant Gabriel Moraga ventured in to the central valley from the coastal mission at San Jose to find more potential sites for new Spanish Missions. According to written history, Moraga was the first non-native explorer to enter what is now the San Joaquin Valley.

During his trek, he named a small creek after Saint Joachim, who was the father of Mary, the Virgin mother of Jesus Christ. "Saint Joachim" translates, in Spanish, to "San Joaquin". It was later discovered that the creek fed in to a larger river, which then took on the same name. Thus, the San Joaquin River was named.

Being the major tributary through the valley, the name of the river soon propagated to the entire central Valley, becoming known as the San Joaquin Valley.

In 1850, California named the county that bordered the river as "San Joaquin County".

Thus, the name came from a Spanish Explorer, who named a small creek after Saint Joachim, the father of Mary.
