Nevada officials filed a federal lawsuit challenging the Trump administration’s order for cuts in water use Monday, marking a major escalation of tensions between the seven states that share the Colorado River. The complaint, filed in the U.S. District Court of Nevada, asserts that the U.S. Bureau of Reclamation’s operating plan unlawfully authorizes the federal government to reduce the state’s allocation of the river by up to 71 percent annually sometime over the next 10 years. Such a cut would slash the state’s share of 300,000 acre-feet down to 86,444 acre-feet. Nevada’s use, after cashing in water recycling credits with its state-of-the-art system, came in at 198,000 acre-feet last year.
“There are four states upstream of us that are facing zero mandatory reductions,” said John Entsminger, general manager of the Southern Nevada Water Authority, in a Monday interview. “That is not going to balance the system. This is a system-wide problem. It requires system-wide solutions.”
Lawyers for the Colorado River Commission of Nevada, the water authority and the state as a whole requested an injunction to halt implementation until federal documents can reflect the toll water cuts would have on Southern Nevada’s $180 billion economy.
“This shortfall will cause devastating environmental, socioeconomic, and health and human safety impacts to southern Nevada and its citizens,” attorneys wrote. “Federal Defendants failed to consider such impacts in any meaningful way.”
While 2027 and 2028 will see allocation cuts that the Lower Basin states of Nevada, California and Arizona have already agreed to, the years 2029 to 2036 could bring much harsher reductions. Entsminger said he felt it was important for Nevada to have its own representation on the issue, but he added he would be surprised if California and Arizona don’t sign on to the lawsuit, considering officials remain aligned in their positions. No mandatory cuts will be imposed on the Upper Basin states of Colorado, Utah, New Mexico and Wyoming. Entsminger submitted a letter to all six Colorado River basin states Monday, saying the state’s decision to sue wasn’t made lightly but that “hiding from reasonable legal interpretations in order to defer hard political decisions helps no one over the long term and further endangers our shared resource.”
