Yolo County’s Statistical and Demographic Profile
History of Yolo County
Yolo County was one of the original 27 counties created when California became a state in 1850. “Yolo” may be derived from the native Poewin Indian word “yo-loy” meaning “abounding in the rushes.” Other historians believe it to be the name of the Indian chief, Yodo, or the Indian village of Yodoi.
The first recorded contact with Westerners occurred in the late 1830s. These included Spanish missionaries as well as trappers and hunters who could be found along the banks of “Cache Creek” – named by French-Canadian trappers. The first white settler was William Gordon who received a land grant from the Mexican government in 1842 and began planting wheat and other crops.
The towns of Yolo County first developed along the Sacramento River. Its first town, Fremont, was founded in 1849 along the confluence of the Sacramento and Feather Rivers and became the first county seat. Knights Landing, Washington, Cacheville (later called Yolo), Clarksburg, Winters, Esparto, Capay, Guinda, and Davisville (Davis) were all built near waterways. Davisville had the added advantage of being on the path of the newly constructed railroad. Woodland, which became the county seat in 1862, began in a wooded area of valley oaks and was also served by a nearby railroad.
Current Demographics
Yolo County 1,021 square miles (653,549 acres) is located in the rich agricultural regions of California’s Central Valley and the Sacramento River Delta. It is directly west of Sacramento, the State Capital of California, and northeast of the Bay Area counties of Solano and Napa. The eastern two-thirds of the county consists of nearly level alluvial fans, flat plains and basins, while the western third is largely composed of rolling terraces and steep uplands used for dry-farmed grain and range. The elevation ranges from slightly below sea level near the Sacramento River around Clarksburg to 3,000 feet along the ridge of the western mountains. Putah Creek descends from Lake Berryessa offering fishing and camping opportunities and wanders through the arboretum of the University of California at Davis. Cache Creek, flowing from Clear Lake, offers class II-III rapids for white water rafting and kayaking.
Yolo County sits in the Pacific flyway, a major migration route for waterfowl and other North American birds. Several wildlife preserves are situated within the county. The Yolo Bypass Wildlife Area has been recognized as one of the most successful public-private partnerships for wildlife preservation. It provides habitat for thousands of resident and migratory waterfowl on more than 2,500 acres of seasonal and semi-permanent wetlands.
Over 88% of Yolo County’s population of 200,709 (as of 1/1/09) residents reside in the four incorporated cities. Davis, founded in 1868, now with a population of 66,005, has a unique university and residential community internationally known for its commitment to environmental awareness and implementing progressive and socially innovative programs. Woodland, population 56,399, is the county seat. It has a strong historic heritage which is reflected in an impressive stock of historic buildings in its downtown area and surrounding neighborhoods. West Sacramento, population 47,782, sits across the Sacramento River from the state’s capital of Sacramento. It is home to the Port of Sacramento which ships out 1 million tons of some of Yolo County’s many agricultural products, such as rice, wheat, and safflower seed, to world wide markets. West Sacramento is also home to Triple-A baseball team, the Rivercats. The City of Winters, population 7,052, is a small farming town nestled at the base of the Vaca Mountains and offers unique shops, restaurants, galleries and live entertainment at the Palms Playhouse. It is close to Lake Berryessa and has become a favorite destination for bicycle enthusiasts.
