TUOLUMNE COUNTY, California — October 29, 2026. The Tuolumne Utilities District has completed an environmental approval step for a long-term water-service contract with the U.S. Bureau of Reclamation, a decision described in a new state filing received October 28, 2026. The contract framework would allow up to 6,000 acre-feet of Central Valley Project water per year for beneficial uses within the district’s service region and the lands of the Chicken Ranch Rancheria Tribe of Me-Wuk Indians.

How would the potential water supply be divided?

The state’s Notice of Determination assigns 2,500 acre-feet per year to uses within TUD’s existing service area and 3,500 acre-feet per year for the Chicken Ranch Rancheria Tribe, for uses primarily involving agriculture, residences and commercial activity within its federally recognized trust boundaries. These are authorized quantities described in the project, not a guarantee that the maximum volume will be delivered in every year.

What did the district approve?

The environmental record gives October 27, 2026 as the district’s project approval date. It identifies the project as approval of a long-term water-service contract with Reclamation, intended to enhance supply reliability and provide a mechanism to serve existing and planned demand. The district concluded the action would not have a significant environmental impact and used a mitigated or negative declaration rather than an Environmental Impact Report.

What does this mean for current customers?

For customers, increased contractual access to water is relevant to long-term reliability, but a water-service contract is not equivalent to a new treatment plant, a completed pipeline or a promise that household rates will decrease. Actual supply depends on the contract’s operating conditions, available federal water and the infrastructure required to deliver it.

Why the tribal allocation matters

The notice explicitly recognizes the Chicken Ranch Rancheria Tribe of Me-Wuk Indians and its potential access to 3,500 acre-feet annually. Reporting must distinguish the tribe’s allocation from district customer use; they are not two labels for the same water. Any plans for delivery within tribal trust boundaries should be described from tribal and agency records, rather than presumed from county land-use decisions alone.

What should residents look for next?

The key follow-up questions are the contract’s final effective date and term, physical delivery arrangements, federal supply availability, projected operating costs, and any separate local infrastructure decisions. The current filing does not provide evidence that the district has begun withdrawing 6,000 acre-feet annually.
