How is the GSP related to the Napa Valley Drought Contingency Plan?

The Napa Valley Subbasin GSP and the Napa Valley Drought Contingency Plan (DCP) are separate but complementary planning efforts. Although they are independent efforts, opportunities for integration between the plans are expected to be available.  

The Napa Valley DCP is a voluntary planning effort focused on water supply reliability for local water supply agencies. The DCP is being developed as part of the U.S. Bureau of Reclamation’s drought response program which aims to help local water supply agencies better understand and prepare for droughts and mitigate drought impacts. Completion of the DCP provides the opportunity for agencies to competitively compete for future implementation funding for drought resiliency projects described in the DCP. The Napa Valley DCP is currently under development in cooperation with Napa County, Napa Sanitation District, the Cities of Calistoga, St. Helena, Napa, and American Canyon, and the Town of Yountville.  

Both planning efforts will propose projects and management actions to achieve their respective goals. While the two efforts are on slightly different timelines, the Draft Napa Valley DCP is expected to be available in Spring 2021, while the Draft GSP will be available in September 2021, there is opportunity for collaborating on potential joint projects that address both groundwater and drought resiliency.
