SantaClaraCountyGroundwaterSubbasins

Santa Clara County includes portions of two groundwater basins as defined by the California Department of Water Resources (DWR): the Santa Clara Valley (2-9) and the Gilroy-Hollister Valley Basins (3-3). The groundwater subbasins within Santa Clara County managed by the District are the Santa Clara Subbasin (2-9.02) and the Llagas Subbasin (3-3.01). The delineation of groundwater subbasins is necessary to understand the extent of aquifer materials and supports District programs to manage and protect the quantity and quality of groundwater resources. Groundwater subbasin boundaries are updated as new information is available.圣克拉拉县包含由加州水资源部（California Department of Water Resources, DWR）划定的两处地下水盆地的部分区域：圣克拉拉谷（2-9）与吉尔罗伊-霍利斯特谷盆地（3-3）。由该管理辖区负责管控的圣克拉拉县境内地下水子盆地包括圣克拉拉子盆地（2-9.02）与拉加斯子盆地（Llagas Subbasin, 3-3.01）。划定地下水子盆地是明确含水层介质分布范围的必要前提，同时可为该辖区开展地下水资源数量与质量的管理及保护工作提供支撑。地下水子盆地的边界将根据新获取的相关信息进行更新调整。
