How does Dinkey Creek Inn compare with other water systems in Fresno County?
By EPA's size categories, Dinkey Creek Inn is a very small system (500 people or fewer). Fresno County has 328 active public water systems. Its population served is well below the county average of 3,205 people per system, and accounts for less than 0.1% of the 1,051,276 people reported by systems filed under the county. Across California, the 7,479 active systems average 5,706 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Dinkey Creek Inn is well below that figure.

California has 3,016 active transient non-community water systems, 40% of the state's 7,479 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,179 California systems (83%) list groundwater as their primary source.
Who owns and regulates Dinkey Creek Inn?

Does Dinkey Creek Inn have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in August 2024. The violations listed here began between January 2015 and August 2024. By type: 9 monitoring and 3 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (9 of them). EPA lists 11 as resolved 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. 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.
