Quinebaug Lake State Park in Killingly, Connecticut, encompasses 181 acres around Wauregan Reservoir and centers on an 88-acre natural lake enlarged by a dam at its outlet. Also known as Quinebaug Pond and Quinebaug Lake, the lake is fed by Quinebaug Brook, or Quandock Brook, and reaches depths of 31 feet. The reservoir and surrounding land entered the Connecticut Register and Manual as Quinebaug Lake State Park in 1964. Managed by the Connecticut Department of Energy and Environmental Protection, the park is especially associated with fishing, non-motorized boating, and small-craft access, and the lake is designated by the state for bass management.
