SACRAMENTO, Calif. (AP) California regulators are planning to stop thousands of farmers from taking water out of the states major rivers and streams because of a worsening drought.

The Sacramento Bee reported that the State Water Resources Control Board will vote on the emergency curtailment order Aug. 3. If approved, it would take effect about two weeks later. There would be exceptions for drinking water and other needs.

The order shows the effect the drought is having on Californias water supply, said Eileen Sobeck, the boards executive director. Sobeck told the newspaper that there is just not enough to meet all of the legitimate demands.

We dont take this action lightly; we know that its going to impose hardships on folks, she said.

The western United States is in the midst of an historic drought that is emptying reservoirs and contributing to massive wildfires .

Extreme conditions like these are often from a combination of unusual random, short-term and natural weather patterns heightened by long-term, human-caused climate change. Scientists have long warned that the weather will get wilder as the world warms. Climate change has made the West much warmer and drier in the past 30 years. Special calculations are needed to determine how much global warming is to blame, if at all, for a single extreme weather event.

During the previous drought in the mid 2010s, state officials imposed restrictions on farmers, but stopped short of issuing a blanket order like this.

California Gov. Gavin Newsom has asked everyone to voluntarily cut their water use by 15%. He has issued an emergency drought proclamation that covers 50 of the states 58 counties, or about 42% of the states population. Californias population centers including Los Angeles, San Diego and San Francisco are not included.

Farmers water allocations this year have already been dramatically reduced. This new order will further weaken their ability to produce this year, said Karen Ross, secretary of of the state Department of Food and Agriculture. But she said the move is absolutely necessary.
