Park County Lake Quality

Montana, 25 lakes, measured by Montana DEQ

There are 25 monitored lakes in Park County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. The 25 monitored lakes in Park County carry whatever clarity, phosphorus, and chlorophyll-a readings Montana DEQ has published, shown as reported.

Many of the county's lakes are deep glacial basins, over 50 feet at their deepest point, which gives them thermal stratification and a buffer against summer warming.
