Agriculture in San Joaquin County

On February 18, 1850, California became a State of the Union and 27 counties were created. One of these was San Joaquin County. Captain Charles M. Weber was instrumental in developing the City of Stockton as the County Seat and as a Port of Entry. Today, ships still deliver cargo to the Port of Stockton by the channel Captain Weber had dug in the 1800s.

It is named for one of its major waterways, the San Joaquin River.  The county covers 1,426 square miles (3,694 km) and has a population of about 660,000 (2005).

San Joaquin County is located at the northern end of the San Joaquin Valley and includes the San Joaquin Delta area. About 4,000 farms are located in the county with an average size of 202 acres.

Tourism is an emerging industry in northern San Joaquin county, primarily due to the Lodi wine appellation and the efforts of the Lodi-Woodbridge Wine grape Commission, the Lodi Convention and Visitors Bureau, and the Stockton Convention and Visitors Bureau.

San Joaquin County is growing rapidly and regional planners expect its population to double by the year 2030 and to triple by 2050—the fifth fastest-growing county in California.
