Natural lakes
Otis Reservoir is a 4 km2 reservoir located primarily in Otis, Massachusetts, United States. Small portions are also in Tolland, MA, and Blandford, MA. The lake is popular for boating, swimming, fishing, water skiing, snowmobiling, camping, and water-related recreation. Fish include bass, white perch, yellow perch, tiger muskies, catfish, and bluegills. The reservoir is stocked with trout by the Massachusetts Division of Fisheries & Wildlife.
The current lake was formed from the flooding of three ponds, Rand, Little and Msssenger Ponds in 1865, by a dam across the Fall River, a tributary of the Farmington River created by the Farmington River Power Company.
