Knox County Lake Quality

Maine, 28 lakes, measured by Maine DEP

There are 28 monitored lakes in Knox County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. The 28 monitored lakes in Knox 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.
