Kandiyohi County Lake Quality

Minnesota, 35 lakes, average grade C (Fair)

There are 35 graded lakes in Kandiyohi County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. Kandiyohi 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 Long Lake (A); the most-stressed is Long Lake (F).

NR = not rated: the monitoring record does not meet the evidence bar for a grade. That is EPA Integrated Reporting Category 3 (insufficient information), not a failing grade. How grading works.
