Hancock County Lake Quality

Maine, 143 lakes, measured by Maine DEP

Hancock County in Maine carries 143 monitored lakes — one of the lake-richer counties in our dataset. Coverage that dense usually reflects active lake-association sampling alongside state-agency monitoring. 4 of those lakes carry recent nutrient and algae readings. The county-level summary describes that subset, not every water body listed. On average, Hancock County lakes carry some of the lowest phosphorus and chlorophyll-a readings in Maine, with clear summer transparency across most monitored basins.

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. Killman Pond has the lowest nutrient and algae readings in the county.
