Somerset County Lake Quality

Maine, 169 lakes, measured by Maine DEP

Somerset County in Maine carries 169 monitored lakes — one of the lake-richer counties in our dataset. Coverage that dense usually reflects active lake-association sampling alongside state-agency monitoring. The 169 monitored lakes in Somerset 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.
