Chittenden County Lake Quality
Vermont, 13 lakes, measured by Vermont DEC
Chittenden County has 13 monitored lakes — a thin enough sample that one or two stressed lakes can move the county average noticeably. Use the per-lake pages below for what actually matters. 8 of those lakes carry recent nutrient and algae readings. The county-level summary describes that subset, not every water body listed. For Chittenden County the spread behind the average matters more than the average itself: a few nutrient-rich lakes among many clear ones produce the same figure as the inverse.
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 Malletts Bay Lake.
