Otsego County Lake Quality
New York, 1 lakes, average grade B (Good)
Only 1 lakes in Otsego 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. With an average grade of B, Otsego County sits comfortably above the New York median.
Most of the county's monitored lakes are shallow — under 50 feet — which means wind keeps the water column mixed all summer and sediment-bound phosphorus releases back into the surface layer whenever the bottom is disturbed. Canadarago Lake (B) is the cleanest in the county.
