TROUTBECK RISE LAKESIDE EST WATER SYSTEM is one of 1,084 community water systems in Montana in the 500 or fewer people size category, formerly serving 250 people from groundwater.
EPA's federal records list this system as inactive in 2019; the record below is historical.
As of August 1, 2026, its federal record holds 8 entries between 1997 and 2012, all of which EPA lists as closed. Nothing has been added since 2012.
All 8 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, the Lead and Copper Rule, and inorganic chemicals.
