In the agency’s own words

West Thompson Lake Campground is located near the wooded shoreline of its namesake lake in northeastern Connecticut. The natural setting surrounding West Thompson Lake can be enjoyed year round. Visitors come to the lake for camping, fishing, boating, kayaking and hiking. Keep reading

Recreation

West Thompson Lake provides great boating, kayaking, canoeing and fishing opportunities. It has an excellent population of warm-water fish, including bass and small panfish. A boat ramp is located near the campground for easy access to the water. The Thompson Section of the Quinebaug River Water Trail offers a leisurely three-hour outing for paddlers who are comfortable with moving water. The trail has no rapids or portages and meanders through extensive wildlife habitats. An 18-hole disc golf course is located on the lakeshore and is free to the public. This challenging course is known for its long drives and scenic views of the lake and dam.

Facilities

The entrance gate to the campground is closed from 9pm - 8am. The campground offers 11 campsites with electric and water hookups, 11 basic sites without hookups and two Adirondack lean-to shelters. Amenities include accessible flush toilets and showers, and a dump station. An amphitheater, playground, basketball court, and interpretive trails are located on-site.

Natural Features

The campground is nestled in a forest of Eastern white pine, Northern red oak and Shagbark hickory. Shade is abundant throughout the campground, and autumn leaves put on a beautiful show. An overlook at the dam offers pleasing panoramic views for sightseers and photographers.

Who keeps the booking fee

The agency’s own policy text says the reservation fee and the cancellation processing fee are “retained by the reservation service contractor”, and that a campground concessionaire will decline to refund them because “they did not receive these fees”. Recreation.gov is run under contract by Booz Allen Hamilton. What share of your booking fee the contractor keeps isn’t published in any federal dataset we can read, so we print no number for it.

OpenStreetMap has no toilet mapped within 1 km of this campground, so no site here carries a toilet distance. That’s a gap in the map, not a finding about the campground.

How we know

every fact on this page, and where it came from
Right now: U.S. Army Corps of Engineers publishes no season and no closure for this campground, and it takes no bookings we can read. That’s a gap in the record and not a locked gate: the number below is the only way to be sure.
Cell signal: the Army Corps’s own campground description, read as text by CAMPANAC. None of this is a measurement. It’s what the land manager published about the place, and phones, carriers and weather all disagree with each other; treat it as a warning, not a promise.
Nearest place of any size: Mechanicsville, CT, 0.6 mi WNW (a census designated place). Straight line.
