Aug. 24 (UPI) — Nevada Attorney General Michelle Briggs filed a lawsuit against the Trump administration on Monday over its plan to reduce water use from the Colorado River.

The lawsuit said the drought management plan from the Interior Department would cause “devastating environmental, socioeconomic, and health and human safety impacts to southern Nevada and its citizens.”

The plan also called for cuts to water deliveries to Arizona and California.

Briggs argued that the government misinterpreted, misapplied and violated the Law of the River, a compact that regulates water distribution from the Colorado River to seven states across the Southwestern United States.

“Not surprisingly given the lack of transparency, the Final [Environmental Impact Statement] contains many instances in which the approach taken in the [Record of Decision] and preferred alternative violate the Law of the River,” the lawsuit read.

The cuts proposed by the Trump administration could amount to up to a 71% reduction in the state’s Colorado River water allocation, Nevada officials said.

About 90% of the water used by Las Vegas and the surrounding area comes from the Colorado River.

“This isn’t about political posturing,” Gov. Joe Lombardo said in a statement on Monday. “This is a matter of survival for a community that represents about two-thirds of our state’s citizens and the lion’s share of its economy.”

The Colorado River Basin is experiencing historically low runoff and reservoir levels following decades of unprecedented drought spurred on by climate change.
