Comprehensive Groundwater Management and Monitoring

The goal of the YCWA’s Groundwater Management Plan is to maintain a viable groundwater resource for the people of Yuba County. Initially developed and adopted in 2005, the GMP has since been updated as part of YCWA’s continued stewardship of the county’s water resources.

Between 1948 and 1981, groundwater elevations in the South Yuba subbasin declined an estimated 130 feet. In 1984, YCWA began delivering surface water from New Bullards Bar Reservoir to the subbasin to offset groundwater extraction, resulting in a groundwater elevation rise to near-historical levels.

The purpose of the YCWA GMP is to build on and formalize the successful management of the county’s groundwater resource through the development of a framework for implementing future activities.

YCWA works cooperatively to manage groundwater resources with its member unit water suppliers, which have included: Ramirez Water District, Cordua Irrigation District, Browns Valley Irrigation District, Hallwood Irrigation Company, Brophy Water District, Wheatland Water District, Dry Creek Mutual Water Company and South Yuba Water District.

Surface water and groundwater conjunctive management is at the core of YCWA’s commitment to resource management. Accordingly, YCWA monitors North and South Yuba groundwater subbasin levels in cooperation with the California Department of Water Resources, measuring groundwater quality, conducting groundwater studies and exercising the groundwater resource for the benefit of the county and state.

Over the past several decades, YCWA has met water resources management challenges brought on by floods, droughts and instream flow requirements, investing substantial time and resources in planning efforts.
