History
Yuba County was one of California's original counties, formed in 1850 at the time of statehood. Parts of the county's territory were given to Placer County in 1851, to Nevada County in 1851, and to Sierra County in 1852.

The county was named after the Yuba River by Captain John Sutter for the Maidu village Yubu, Yupu, or Juba near the confluence of the Yuba and Feather Rivers. General Mariano Vallejo said the river was named Uba by an exploring expedition in 1824 because of the quantities of wild grapes (uvas silvestres in Spanish) that they found growing on its banks.

Geography
According to the U.S. Census Bureau, the county has an area of 644 sqmi, of which 12 sqmi (1.9%) are covered by water. It is California's fifth-smallest county by area. The county lies along the western slope of the Sierra Nevada, the steep slopes making it prime territory for the siting of hydroelectric power plants.

Part of the county, where Marysville (the county seat) and most of the population lives, is west of the mountains on the valley floor; a great deal of agricultural business occurs in this part of the county, especially fruit orchards, rice fields, and cattle ranching.
