The federal government announced a two-year operating plan for the Colorado River on August 21, 2026. Arizona, California, and Nevada must collectively reduce their annual water use from the river by 1.25 million acre-feet, starting in 2027 — Arizona takes the largest cut at 760,000 acre-feet (roughly a 27% reduction), California cuts 440,000 acre-feet (about 10%), and Nevada cuts 50,000 acre-feet (about 16%). The four Upper Basin states — Colorado, Utah, Wyoming, and New Mexico — face no mandatory cuts. Lake Mead is at 27% of capacity and Lake Powell is at 22% — both record lows this month, and the lowest combined level since 1957.

1. The Lower Basin Is Carrying Everyone (Arizona Gov. Katie Hobbs, Nevada Gov. Joe Lombardo)

The Lower Basin cut first and cut hardest — and now the federal plan sends them back for another round without touching the Upper Basin.

The burden is landing on the wrong states. Arizona faces a 27% reduction; Nevada faces a 16% cut; the Upper Basin faces nothing mandatory. Arizona Gov. Katie Hobbs called the plan "unacceptable options that include the federal government forcing Arizona to take the majority of draconian water cutbacks." Nevada Gov. Joe Lombardo said the plan "seeks to impose unrealistic reductions on Nevada" and vowed to "fight any outcome that hits Nevada communities unfairly."

Nevada's share doesn't justify its cuts. John Entsminger, General Manager of the Southern Nevada Water Authority, pointed out that Nevada gets just 1.8% of the river's water — yet still faces 50,000 acre-feet of mandatory reductions. Phoenix Mayor Kate Gallego called it "wrong to lay a disproportionate share of the burden on Arizona." Arizona's legislature agreed: Senate President Warren Petersen and Pro Tempore T.J. Shope said they won't accept uneven burden-sharing.

Arizona is preparing a legal challenge. The Arizona Department of Water Resources retained a top law firm and described the plan as containing "fundamental legal flaws," reserving "the right to seek the resolution of its Compact rights in an appropriate judicial forum."

California is more cautious than Arizona. The Metropolitan Water District called the plan "a necessary step forward" — but insisted that Lower Basin cuts alone won't be enough and that all seven states need to reach an agreement. California faces the smallest proportional cut of the three states, about 10%.

2. But the Upper Basin Isn't Overusing Anything (Governors of CO, UT, WY, NM)

The four upstream states say they're already constrained by drought — they're not the reason the river is shrinking.

The Upper Basin isn't taking water it doesn't have. The 1922 Colorado River Compact gives Upper Basin states 7.5 million acre-feet per year, but they only use about 3.75 million — well under their legal share. Officials argue they're already "cutting by nature" because drought has limited snowmelt runoff. The four governors issued a joint statement saying they're "encouraged" that the plan "will better reflect existing water supply."

The Interior Department can't force them to cut anyway. Federal law does not give the Interior Department authority to impose mandatory reductions on Upper Basin states under the current Compact structure. The federal plan asks for voluntary conservation of up to 200,000 acre-feet per year — about 5% of the Upper Basin's annual use.

3. The Farmers Have Already Paid (Nancy Caywood, Caywood Farms; Paul Brierley, Arizona Dept. of Agriculture)

Prior cuts already gutted Arizona's farm sector — the new reductions will end what's left.

Yuma County feeds most of the country's winter produce. Arizona's Yuma County produces 90% of U.S. and Canadian leafy greens during the winter months. Federal projections suggest deep cuts could fallow up to 40% of Yuma farmland — wiping out a large share of the nation's winter vegetable supply.

Some farms are already gone. Nancy Caywood, co-owner of Caywood Farms in Casa Grande, says her land has been largely fallowed since the 2021 water cuts. The local canal is now empty; she can no longer grow cotton or alfalfa. "We can provide food for our nation and also the world," she said. "When they do the cutbacks, and the farmers get cut back, they're just taking away a food source."

The damage runs past the farm gate. Paul Brierley, Arizona's Department of Agriculture Director, warns that reduced water leads to reduced farm hiring, reduced equipment purchases, and a broader rural economic contraction. Agriculture uses over 70% of Arizona's water supply — cuts don't stay on the farm.

4. The River Won't Wait for a Better Deal (Jennifer Pitt, National Audubon Society; Kyle Roerink, Great Basin Water Network)

Conservationists support the federal plan because the states have had years to fix this and haven't.

The reservoirs are nearly at a point of no return. Lake Powell is just 30 feet above the minimum power pool — the level at which Glen Canyon Dam stops generating electricity for the region. Lake Mead hit a record low of 1,040 feet this month. Combined, the two reservoirs haven't been this empty since 1957.

The states haven't fixed this themselves. Current governing rules expire in October 2026, and the seven states have failed to agree on a long-term replacement after years of negotiations. Jennifer Pitt, Colorado River program director at the National Audubon Society, said the federal framework "avoids the basin lurching from one emergency decision to the next, as we have in the past few years, while leaving the door open for the states to reach agreement."

The crisis is also an opening. Kyle Roerink, senior adviser at the Great Basin Water Network, called the moment an opportunity "to prepare for the next hundred years in a meaningful way." Conservation groups say the federal intervention is forcing action that state negotiations alone couldn't deliver.

Where This Lands

Arizona and Nevada say the plan imposes cuts that all seven states should be sharing — and Arizona is moving toward a legal challenge on Compact grounds. The Upper Basin states say they're already operating under natural constraints, not taking more than the river provides. Arizona's farmers are past the policy debate: many operations have already failed since 2021, and more cuts will end what's left. Conservationists back the federal plan because the alternative — seven states litigating while the reservoirs drain — ends badly for everyone. The current governing rules expire in October 2026. With no seven-state agreement in sight, the two-year federal plan may be the floor of what's coming, not the ceiling.
