Lying at the confluence of the American and Sacramento rivers,
Sacramento is known as the “river city.” It’s a good moniker for
the rest of the region, whose communities are located in all or
parts of numerous watersheds including the Cosumnes, lower
Mokelumne and Yuba rivers, as well as the Sacramento-San Joaquin
Delta. These rivers provide the region with much of its surface
water, but groundwater also is an important resource for many
area cities and rural landowners.
