Upper Lake County Water District supplies Upper Lake: about 76% of residents live in its service area. Cal 20 Village and Meadow Pointe Park serves another 15%.

No health-based violations reported to EPA in the five years to October 2026, like 78% of the 5,327 systems serving 501–1,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2023–Dec 2025, was 0.0 ppb, below the 15 ppb action level that applied. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
