Wallum Lakeis a 322-acre lake with the northern half in Douglas, MA and the southern half in Burrillville, RI. The water is beautiful and crystal clear as there is very little aquatic vegetation. The western shore is undeveloped while the eastern shore is lined with summer cottages and year-round homes. The western shore is part of Douglas State Forest and stunning forest covered hills provide great views from the water. Fishing, boating, and swimming are all popular at this picturesque lake. There are two paved boat ramps, one at the north end off Wallum Lake Road in Douglas and the other at the southern end in Burrillville.
