California faces 440,000 acre-foot Colorado River cut under new federal drought plan

The U.S. Department of the Interior on August 21 released new Colorado River operating guidelines requiring California, Arizona, and Nevada to collectively cut their water allocations by 1.25 million acre-feet annually for 2027 and 2028 — a sweeping federal response to what officials describe as the worst drought crisis the river basin has faced in modern times.[1]

Under the plan, Arizona absorbs the largest reduction at 760,000 acre-feet annually, followed by California at 440,000 acre-feet and Nevada at 50,000 acre-feet.[1] Big Bear Valley draws its municipal water from a mix of local groundwater and imported State Water Project supplies rather than directly from the Colorado River, but the cuts affect the broader Southern California water grid that millions of residents — including those in the San Bernardino Mountains — ultimately rely on. A local water manager could not be reached for comment on what the reductions mean specifically for Big Bear Valley ratepayers.

The urgency behind the cuts is stark. The Colorado River Basin has been experiencing what the Bureau of Reclamation calls "unprecedented drought" for 26 years, resulting in historically low reservoir levels.[1] Lake Powell and Lake Mead — the two largest reservoirs in the country — have now fallen to their lowest combined levels since before Lake Powell began filling after the closure of Glen Canyon Dam's gates in 1963.[1] The river system supports more than 40 million people, 5.5 million acres of farmland, 30 tribal nations, and major hydropower operations across the West.[1]

The new guidelines are the first issued under a broader 10-year decision framework and take effect October 1, 2026.[1] Beyond the mandatory allocation cuts, the Lower Basin states are also called on to voluntarily conserve and store at least 700,000 acre-feet collectively over the two-year period.[1]

California officials signed on to the plan but made clear they see it as a stopgap. "This is a bridge, not a permanent solution," said J.B. Hamby, California's Colorado River commissioner, adding that "three states cannot carry the responsibility of all seven."[1] Gov. Gavin Newsom echoed that view, stating that "any long-term solution must share responsibility fairly across all seven states in recognition of the new reality of the Colorado River" and calling on every state across the basin to "step up to conserve water."[1] The four Upper Basin states — Colorado, Wyoming, Utah, and New Mexico — are not subject to mandatory cuts under the current guidelines; no Upper Basin official was quoted in available reporting.

What's next

The 2027–2028 operating guidelines take effect October 1, 2026.[1] Negotiations over a permanent, seven-state framework are expected to continue in the months ahead. Big Bear News will seek comment from local water district managers on how — if at all — the reductions may filter down to valley residents and businesses.
