Lake Whitingham (also known as Harriman Reservoir) is the largest lake entirely within the state of Vermont. Fully eight miles long from north to south with over twenty-eight miles of undeveloped shoreline. The lake was created by building the largest earthen dam. It stands 200' tall, 1200 feet across, and a quarter of a mile wide at it's base. By the dam is the "glory hole," an enormous 160' spillway shaped like a gigantic morning glory. Boating, fishing, swimming and picnicking are all available around the lake maintained by the New England Power Company at no cost to the public.
