Our Mission: To manage and conserve water and other resources for the citizens of Butte County.

West Butte Subbasin

Basin Information

The portion of the Sacramento Valley Groundwater Basin bounded on the west and south by the Sacramento River, on the north by Big Chico Creek, on the northeast by the Chico Monocline, and on the east by Butte Creek comprises the West Butte Subbasin. Big Chico and Butte Creeks serve as subbasin boundaries in the near surface. The subbasin is hydrologically contiguous with the Vina and East Butte Subbasins at depth. The Chico Monocline forms a geographic boundary; however, a component of recharge to the subbasin appears east of the fault structure. Groundwater flow is southwesterly toward the Sacramento River north of the city of Princeton. South of Princeton, groundwater flows away from the Sacramento River to recharge the groundwater system. Annual precipitation within subbasin is approximately 18 inches in the valley increasing to 27 inches towards the foothills. (West Butte overview)
