LOST LAKE is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 328 people from groundwater.
As of August 1, 2026, its federal record holds 14 entries between 1994 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.
All 14 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 inorganic chemicals.
