Orange County Lake Quality

Vermont, 9 lakes, average grade A (Excellent)

Only 9 lakes in Orange County carry an active grade. The county-level summary is therefore representative of those specific lakes, not necessarily of every water body in the county. On average, Orange County lakes grade an A. That puts it near the top of the {{stateName}} county ranking.

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 Fairlee (A); the most-stressed is Harriman Pond (B).
