Caledonia County Lake Quality

There are 34 monitored lakes in Caledonia County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. 9 of those lakes carry an A–F grade. The county-level summary describes that subset, not every water body listed. On average, Caledonia County lakes grade an A. That puts it near the top of the Vermont county ranking.

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. Peacham Pond (A) is the cleanest in the county.
