One mile from the border

At 231 acres, Third Connecticut Lake is the third largest of the four Connecticut Lakes and the second deepest. Launch your boat from the accessible boat ramp to enjoy not just the outstanding fishing, but the sounds and sights of some of the most pristine wilderness you are likely to encounter. Fish the deeper waters for rainbow trout and lake trout in warmer months and rainbow trout, cusk and lake trout in winter.

Third Connecticut Lake is located 20 miles from the village of Pittsburg. It is just one mile south of the .S./Canadian border and the legendary Magnetic Hill. Remarkably, the expansive lake is fed by the Fourth Connecticut Lake, a small pond just to the south of the Canadian border.

This lake is undeveloped and primarily fished by boat though some wading is possible in the area of the boat launch. It is possible to walk north along the shore for quite a distance. You may hear or see pairs of nesting loons. Rarely will you encounter more than one or two anglers at this beautiful spot.
