SAN JOAQUIN. County seat, Stockton. Created February 18, 1850. The county takes its name from the San Joaquin River. In the early 1800’s Lieutenant Moraga, commanding an expedition in the lower great Central Valley of California, gave the name of San Joaquin (meaning Saint Joachim) to a rivulet that springs from the Sierra Nevada mountains and empties into Buena Vista Lake.
