Aroostook County Lake Quality

Maine, 153 lakes, measured by Maine DEP

Aroostook County has 153 monitored lakes, enough that within-county variation matters as much as the county average. Some are deep glacial basins, others are shallow agricultural-watershed waters, and the measurements reflect that mix. The 153 monitored lakes in Aroostook County carry whatever clarity, phosphorus, and chlorophyll-a readings Maine DEP has published, shown as reported.

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.
