California Gov. Gavin Newsom asked residents on Thursday to voluntarily cut back on their water usage this summer amid the drought and high temperatures, according to reports.

"We’re hopeful that people will take that mindset they brought into the last drought and extend that forward with a 15% voluntary reduction, not only on residences but industrial commercial operations and agricultural operations," Newsom said in a news conference, according to The Los Angeles Times. 

With his recall election two months away, the governor has so far refrained from mandating water restrictions. 

Newsom also expanded the regional state of emergency to nearly half of the state, according to the newspaper.

He suggested watering the lawn less, taking shorter showers and fixing leaks. "We’re not trying to be oppressive," Newsom stressed, The Times reported. "Again, these are voluntary standards."

The Sept. 14 recall became official earlier this summer after elections officials confirmed the required number of signatures on the recall petition. 

CALIFORNIA GOV. GAVIN NEWSOM RECALL VOTE SET FOR SEPT. 14

Newsom would be recalled if more than 50% of voters casting ballots in the fall say they’d like him replaced and the challenger with the most votes would take over as governor. 

The recall was prompted by Republicans and other critics of Newsom’s pandemic restrictions and will be the second in the state’s history following 2003 when former Gov. Arnold Schwarzenegger was elected. 

Recent polls have shown strong support for Newsom. 

Firefighters battled several wildfires in Northern California this week and California's most important reservoirs are already at dangerously low levels and will likely reach historic lows later this year. Lake Oroville in Northern California is at 30% capacity, and state officials worry water levels could get so low they might have to shut down a hydroelectric plant later this year. Along the Russian River, officials fear Lake Mendocino could empty later this year.

"This is jaw-dropping, what's happening in the West Coast of the United States," Newsom said Thursday at Lopez Lake, a reservoir in San Luis Obispo County formed by a dam on the Arroyo Grande Creek that is at 34% capacity.

The historic drought tied to climate change is gripping the U.S. West and comes just a few years after California declared its last dry spell over in 2016. The earlier drought in California depleted groundwater supplies and changed how people use water, with many people and businesses ripping out landscaping and replacing it with more drought-tolerant plants.
