Water levels in the Colorado River have dropped to their lowest levels in decades, yet the seven states dependent on the river continue to deadlock over fair allocation of remaining supplies.
Negotiations have stalled for over six months despite persistent talks and twice-eventful interventions by the Trump administration, with states now threatening litigation even as Western communities prepare for steep water reductions. States are openly criticizing a federal water-use plan scheduled for release this summer, escalating tensions that threaten prolonged legal battles amid worsening drought conditions.
The river’s reservoir and canal infrastructure—designed for last century’s climate and population—struggles to manage declining water supplies and explosive regional growth, complicated by water rights dating back to early European settlement. While communities have improved efficiency and cities now use less water despite expansion, fundamental disagreements persist over how to apportion the diminished flow.
“We’ve invested time, effort and money trying to facilitate a multistate agreement,” Scott Cameron, acting commissioner of the Bureau of Reclamation, stated during negotiations culminating in a Carlsbad desalination deal. However, Cameron noted states repeatedly rejected proposed compromises and expressed skepticism about achieving satisfaction with federal measures to prevent reservoirs from hitting critical lows.
Approximately 40 million people and 5.5 million acres of farmland rely on the Colorado, but flows have steadily diminished over two decades as warming and aridification grip the West. The existing water rights system—dating to the 1850s and 1860s—awards each state and Mexico more water than actually available, prioritizing the longest-established uses.
In the lower basin, including California, Arizona and Nevada, communities have accepted significant reductions, with a new proposal asking upstream states—New Mexico, Utah, Colorado and Wyoming—to cut usage as well. However, upper basin states resist permanent annual cuts since meager winter snowpack forces them to reduce use proportionally.
The existing plan expired this winter, with states missing deadlines to agree on replacement guidelines required by October to prevent chaos. A mild winter and extreme spring heat left snowpack severely depleted, pushing Lake Powell—the nation’s second-largest reservoir—near critical hydropower generation levels until emergency federal water transfers stabilized operations.
Cameron indicated the bureau rejected three multistate proposals as inadequate, noting less than $100 million remains from $454 million in conservation funding since the Inflation Reduction Act allocated $4 billion for Western drought response. “We’ve made everyone unhappy, and maybe made everyone mad,” he said.
An Interior Department plan is expected in July for the coming decade, requiring White House approval. Draft options include significant lower basin cuts based on reservoir conditions, with varying emergency shortage levels that could leave some risks of unplanned outages in Arizona, which heavily depends on reservoirs and holds junior water rights.
Two-year adjustment cycles drew bipartisan criticism from state negotiators who argued frequent renegotiation undermines supply certainty—a key goal of talks. Colorado’s Becky Mitchell called it “difficult to fathom,” while Nevada’s John Entsminger deemed it “not at good plan,” though Cameron presented it as the best available option given negotiations’ difficulty.
Litigation threats grow as talks stall, despite negotiators hoping to avoid lengthy, expensive court battles. Senator Mike Lee warned he would block federal drought relief funds from suing states, while Arizona and Colorado have prepared legal teams and allocated public funds for potential conflicts.
States submitted contradictory legal interpretations of the 1922 compact, both suggesting federal plans violate the agreement. Disputes center on whether upper basin states must deliver fixed downstream amounts regardless of conditions, or merely cannot exceed their allotted shares. Arizona argues federal plans improperly favor Lake Powell maintenance over required downstream flows, while Colorado contends plans don’t adequately burden lower basin shortages and could illegally tap upper basin reservoirs.
“The constant renegotiation every two years is difficult to fathom,” said Becky Mitchell, Colorado’s top water negotiator, adding it could increase interstate tensions further.
With the seven-state agreement deadline approaching, Nevada’s John Entsminger noted the 1,700-word compact’s ambiguities virtually guarantee Supreme Court involvement unless states reach consensus. “The only way you’ll have certainty is probably Supreme Court action,” he said. “The way you avoid that is a seven-state agreement.”
