About Yuba County
With the discovery of gold in California in 1848, the Sacramento region became a national and international focus of attention, drawing a mass migration of gold seekers, miners and pioneers to the area.
At the heart of our county is historic Marysville, framed up on two sides by the Yuba and Feather Rivers. To the south of Marysville, you will find communities with their own rich places in history — including Linda, Olivehurst, and Arboga, as well as our newest community Plumas Lake. This stretch of the county is also where you will find the Toyota Amphitheatre, our state-of-the-art venue for outdoor concerts, and the Yuba-Sutter Gold Sox, a collegiate league baseball team, makes its home in Marysville. And you can always count on encountering numerous local events, active theater and arts groups, social and service clubs and year-round festivals and fairs.
