State water official warns Colorado River negotiations could force significant Upper Basin cuts
Summary
A Division of Water Rights representative told the council the seven‑state Colorado River negotiations may result in substantial Upper Basin curtailments, potential 200,000-acre-foot reductions in short term scenarios and wide legal/priority implications for post‑1922 storage projects; the state will have to implement any allocated curtailments.
A Division of Water Rights representative briefed the Public Lands Council on the status of Colorado River negotiations and the potential implications for Upper Basin water users.
The speaker said negotiators face short deadlines to reach an agreement in principle and warned that if the seven basin states cannot agree, the Bureau of Reclamation may impose its own plan. He outlined two broad approaches discussed in negotiations: cuts based on reservoir elevations (Powell/Mead triggers) or cuts based on a multi‑year average of natural river flow. Either approach would require the Upper Basin states to take defined reductions.
As an example, the speaker said negotiations have discussed an initial upper‑basin reduction of roughly 200,000 acre‑feet that would be taken "off the top" in one scenario, with Utah's share at approximately 23% of the cut in that formulation. He emphasized many water rights (particularly storage projects and post‑1922 rights) are legally vulnerable to curtailment under compact obligations, while pre‑1922 direct-flow rights are more protected.
The speaker said any final apportionment would be administered through interstate and state mechanisms (Upper Colorado River Commission, then to the state engineer), and Utah would then determine how to allocate curtailment among local drainage areas and water-right holders. He urged local agencies and water managers to plan for a range of outcomes and noted that the state is developing systems and data to make administration more precise.
