Annual Fall Ditch Outage

The Pacific Gas and Electric Company (PG&E) Main Tuolumne Canal conveying 95% of Tuolumne Utilities District’s (TUD or District) drinking water supply will be shut down for PG&E’s annual maintenance from Sunday, October 11th through Sunday, October 18th, 2026. TUD is asking you to limit your water use while PG&E undertakes repairs and improvements.

Without water flowing in the ditches, the only water available is what remains in storage tanks and from limited capacity groundwater wells.  Conservation during this period is necessary to ensure adequate water supply for drinking, sanitary usage, and fire protection. Please conserve water by limiting outside watering, avoid washing vehicles, turn off automatic lawn and drip sprinkler timers, and repair water leaks.

For irrigation/agricultural ditch customers, periodic outages will continue from October through December for annual maintenance. Click this link to view the 2026 Ditch Schedule.
