Windham County Lake Quality

Vermont, 25 lakes, measured by Vermont DEC

There are 25 monitored lakes in Windham County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. 9 of those lakes carry recent nutrient and algae readings. The county-level summary describes that subset, not every water body listed. Taken together, the monitored lakes of Windham County sit near the low-nutrient end of the Vermont range.

The county's lakes lean shallow, which makes the readings sensitive to wind, sediment-resuspension, and any nutrient inputs from the watershed. The cleanest measured lake is Lake Raponda.
