Crystal Lake is located near the village of Barton in Orleans County, Vermont, United States.

The lake is owned by the state and managed by the Department of Environmental Conservation.

[1] Exotic species infestations are a concern, with an existing Eurasian water milfoil population, which is being addressed.

There are rainbow trout (wild and stocked), yellow perch, smallmouth bass, rock bass, pumpkinseed, chain pickerel, longnose suckers, white suckers, and various minnow species.

[3] Rogers' Rangers were forced to retreat through the area following their attack on Saint-Francis, Quebec in 1759.

One group followed the Barton River south to the falls at the outlet of Crystal Lake, where they were able to catch fish.
