Colebrook River Lake dominates the central valley of this 2015 study, illustrating the hydrological management of the West Branch Reservoir system across the Massachusetts and Connecticut border. The landscape is defined by its upland terrain, where peaks like Hanging Mtn, Snow Mtn, and Seymour Mtn overlook a series of small, high-elevation water bodies including Pelton Reservoir and Mirror Lake.
