Chisago County Lake Quality

Minnesota, 33 lakes, average grade C (Fair)

There are 33 graded lakes in Chisago County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. Chisago County averages to a C. The distribution behind that average matters more than the letter: a few stressed lakes versus many decent ones can produce the same average as the inverse.

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 Fish Lake (A); the most-stressed is Emily Lake (F).
