Carver County Lake Quality

Minnesota, 40 lakes, average grade D (Poor)

There are 40 graded lakes in Carver County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. On average, Carver County lakes grade D, with phosphorus loading and reduced clarity showing up across most of the dataset.

The county's lakes lean shallow, which makes the grades sensitive to wind, sediment-resuspension, and any nutrient inputs from the watershed. The cleanest lake on the books is Brickyard Lake (A); the most-stressed is Jonathan Lake (F).
