Trail Map        Trails: 7.4 miles         Rating: ★★★☆☆

West Thompson Dam and lake are a massive area providing a whole range of activities including hiking, camping, boating, and disc golf.


At 7.4 miles of blazed trails there is a good amount of hiking here.  I have only explored the western side on trail runs and have never made the full loop around the lake. Trails were a bit rough and muddy on my January visit but very gently rolling and there are plenty of large fields for easy strolling.


The 239 acre lake created by the dam is a good flat water paddling area that allows fishing.  The boat launch is on the western side and there is both a concrete ramp as well as a grassy slope into the water.

This is also a take out spot for paddling on the Quinebaug River.  The put-in for this paddle is boat launch is 5.8 miles upstream at Fabyan Boat Launch.

Disc Golf

West Thompson Lake offers a no charge Disc Golf Course with 18 challenging holes known for long drives. There are eight holes under 300 feet., six holes 300 to 400 feet., and four holes over 400 feet. This course is great for players of all skill levels and ages, and offers scenic views of West Thompson Lake and the Dam.
