In a stark indication of California’s growing water crisis, Gov. Gavin Newsom on Monday declared a drought emergency in 41 counties, including areas of the Central Valley that had urged action on behalf of agricultural growers.

Newsom’s proclamation dramatically expands the drought emergency he declared in Sonoma and Mendocino counties last month, and now covers 30% of the state’s population.

“With the reality of climate change abundantly clear in California, we’re taking urgent action to address acute water supply shortfalls in Northern and Central California while also building our water resilience to safeguard communities in the decades ahead,” Newsom said in a prepared statement. “We’re working with local officials and other partners to protect public health and safety and the environment, and call on all Californians to help meet this challenge by stepping up their efforts to save water.”
