SQUAW CREEK WATER DISTRICT is one of 486 community water systems in Wyoming in the 500 or fewer people size category, serving 160 people from groundwater.
As of August 1, 2026, its federal record holds 12 entries between 1980 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 12, 11 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves the Radionuclides and Revised Rad Rule, the Groundwater Rule, and the Total Coliform Rules.
