How does Town of Dinosaur compare with other water systems in Moffat County?
By EPA's size categories, Town of Dinosaur is a very small system (500 people or fewer). Moffat County has 16 active public water systems, and Town of Dinosaur is the 5th-largest of them by population served. Its population served is about half of the county average of 735 people per system, and accounts for 3% of the 11,766 people reported by systems filed under the county. Across Colorado, the 2,207 active systems average 3,400 people each. Nationally, the average active community water system reports serving 6,703 people, so Town of Dinosaur is well below that figure.
What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. Colorado has 1,068 active community water systems, 48% of the state's 2,207 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,437 Colorado systems (65%) list groundwater as their primary source.
Who owns and regulates Town of Dinosaur?
EPA lists Town of Dinosaur as owned by a local government. The CO state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 2 of the 16 active systems in Moffat County (13%) are also owned by a local government.
Does Town of Dinosaur have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in April 2026. The violations listed here began between December 2020 and April 2026. By type: 7 monitoring and reporting, 2 public notice, recordkeeping or other, 2 required treatment not met and 1 monitoring. The contaminant or rule involved most often is Lead and Copper Rule (6 of them). EPA lists 9 as resolved, 2 as unaddressed and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
