New York, 8 lakes, measured by NY DEC

Monroe County holds 8 monitored lakes.

The county-level summary describes that subset, not every water body listed. Most monitored lakes in Monroe County are productive, shallow basins; each lake page shows its own phosphorus and chlorophyll-a readings beside the EPA condition class.

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 Irondequoit Bay Lake.
