Drought 2014

On January 17, 2014, Gov. Brown declared a drought state of emergency and directed state officials to take all necessary actions in response.  The drought continued through 2014 and into 2015 with record low snowpack conditions. Therefore on March 17, 2015, the State Water Board expanded the emergency water conservation regulations with new restrictions aimed at achieving a statewide reduction in water usage. Please visit the Save Our Water website to find information and tips on how to conserve water. 

Make sure your outdoor irrigation is turned off. Make irrigation scheduling easy, and visit the City of Napa's water conservation page to find out more.

In September 2009, the Napa County Board of Supervisors authorized County staff to begin outreach on a water conservation program in the unincorporated county, specifically targeting the Milliken-Sarco-Tulocay (MST) area. County staff, with input from the agricultural community, the Napa County Resource Conservation District, and the California Department of Fish and Game have come up with some opportunities to help residents, growers, and winery owners alike conserve water.
