LAKESIDE WATER SYSTEM is one of 123 community water systems in Montana in the 501 to 3,300 people size category, serving 1,225 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1995 and 2012, all of which EPA lists as closed. Nothing has been added since 2012.
Of the 3, 2 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 Total Coliform Rules and the Lead and Copper Rule.
