The release of new federal guidelines for the allocation of the Colorado River’s diminishing water supply has sparked legal action from the state of Nevada. In a significant twist for regional water management, Nevada has initiated a lawsuit against the U.S. Department of the Interior, challenging the recently unveiled water-sharing plan.
Nevada Takes Legal Action
On Monday, Nevada’s water authorities formally filed a lawsuit, marking a pivotal moment in the ongoing negotiations between the seven states reliant on the Colorado River. These states have been embroiled in protracted discussions, seeking consensus on how to equitably distribute the river’s shrinking resources. Despite widespread agreement among experts and stakeholders that legal battles are not the ideal resolution, Nevada’s decision brings the issue to the judiciary.
Controversial Federal Plan
The contested federal plan mandates significant water reductions for Lower Basin states, including Arizona, California, and Nevada, while sparing the Upper Basin states such as Colorado, New Mexico, Utah, and Wyoming from similar cutbacks. Nevada’s officials argue that this approach unfairly burdens their state.
The federal plan’s cuts will severely impact urban areas in Phoenix and Tucson, Arizona, as well as parts of Nevada and California.
“The Department of the Interior can’t roll Nevada and solve the entire Colorado River shortage on the backs of the Lower Basin states,” Nevada Gov. Joe Lombardo asserted in a press release. He reiterated Nevada’s willingness to contribute but emphasized the necessity of a collective solution, stating, “Until that happens, we are prepared to fight for as long as it takes.”
The new guidelines grant the Interior Department authority to reduce Nevada’s Colorado River allocation by more than 70%, a stark contrast to a temporary plan that had proposed milder reductions through 2028. Larger cutbacks, however, remain a possibility in the near future.
Arizona’s Response and Legal Implications
Arizona’s leadership is currently deliberating its response to Nevada’s lawsuit. Despite regular consultations with Nevada and California over Colorado River issues, Arizona’s water chief, Tom Buschatzke, was informed of the lawsuit early Monday morning.
Buschatzke remarked, “We’re still evaluating, and we’ll provide more information at a later date on how we’re going to deal with this complaint. But it certainly adds a significant additional level of uncertainty to all of the outcomes facing us.”
The lawsuit’s announcement surprised many water policy observers, including Elizabeth Koebele from the University of Nevada, Reno. “To me, it isn’t necessarily the kind of lawsuit that we often think about, or we might expect,” Koebele commented.
While the focus of previous Colorado River legal discussions has often been on Arizona and potential “compact call” lawsuits, Nevada’s legal approach is distinct. It accuses the federal government of procedural missteps in formulating the new water management strategy, arguing that the Interior Department neglected to adequately consider the socioeconomic impacts on Nevada.
Koebele explained that Nevada’s lawsuit critiques the Interior’s reluctance to tackle fundamental legal issues related to the Colorado River. “Nevada is sort of saying, ‘If you’re unwilling to address some of those debates, then the solutions that you’re putting out aren’t necessarily lawful or fair to us,'” Koebele noted.
Despite the lawsuit’s potential to prolong legal proceedings, Koebele emphasized the urgent need for immediate measures to address the river system’s critical condition, with reservoirs at historic lows.
