Rutland County Lake Quality

Vermont, 42 lakes, average grade B (Good)

There are 42 monitored lakes in Rutland County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. 15 of those lakes carry an A–F grade. The county-level summary describes that subset, not every water body listed. With an average grade of B, Rutland County sits comfortably above the Vermont median.

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 Lake St. Catherine (A); the most-stressed is Little Pond (C).

NR = not rated: there is not enough recent sampling to support a letter. That is EPA Integrated Reporting Category 3 (insufficient information), not a failing grade. How grading works.
