Quaddick State Park

Quaddick State Park is a recreation area in Thompson centered around Middle Quaddick Reservoir with facilities for water and land activities. A sandy beach, boat launch, and loop trail provide multiple ways to enjoy the wooded shoreline.

The land began as Thompson's town farm for elderly residents and was later converted into a forest recreation area. The site became an official state park in 1951.

The Nipmuck Indians utilized the waters of present-day Quaddick Reservoir as their primary fishing grounds before European settlement.

The park accommodates both swimmers and boaters, making it suitable for a half-day or full-day visit. Arriving early helps secure parking and beach space, especially on summer weekends.

The reservoir was created in 1866 by damming Kings Pond and originally served textile mills in Killingly rather than recreation. This industrial history contrasts sharply with its current use as a leisure destination.
