Lake County has 224 registered underground storage tank facilities in the national snapshot — gas stations, fleet yards, and other regulated fuel sites — holding 152 tanks in service and 586 tanks that have been closed or removed, plus 5 temporarily out of service. Over the life of the program, 200 fuel releases were reported here; 123 (62% of records) were investigated and closed with No Further Action, and 36 of those cleanup cases were still open when the snapshot was compiled.

That works out to 50.5 tanks in service per 10,000 residents, well above the Montana average of 30.9 per 10,000. Countywide numbers are context, not a verdict on any parcel — tank risk is hyper-local, falling off within a few hundred feet.
