Things To Do


Located in northwest Connecticut, along the Massachusetts border, Colebrook River Lake lies nestled among multiple state forests and recreation areas. The 700-acre lake is open seasonally for fishing and boating and has a large boat ramp available. The lake and river are stocked with trout by the State. The fall foliage season offers spectacular views from atop the dam and from vessels while boating on the reservoir.

The U.S. Army Corps of Engineers created Colebrook River Lake by building a flood control dam, impounding the West Branch of the Farmington River. It was built as part of the Corps network of flood control dams on Connecticut River tributaries. Construction of the Dam was completed in 1969 and it can store over 16 billion gallons of floodwater. As a flood control lake, the water level can fluctuate significantly. Under a Federal License, a 3.3 megawatt hydroelectric power plant was built by the Hartford Metropolitan District Commission in 1989, selling power to the Connecticut Light and Power Company.
