Removals by watershed Farmington River The Spoonville Dam was a hydropower dam on the Farmington River that had partially washed out in 1955, forcing the water to flow rapidly through a narrow notch. The dam was removed in 2012 to improve boat safety and to allow fish to swim upstream to spawn.
Housatonic River Roraback Pond Dam was a long earthen dam owned by the Connecticut Department of Energy and Environmental Protection impounding a pond on a tributary to Leadmine Brook, itself a tributary of the Housatonic River. The dam was in severe disrepair and was breached in 2021 to remove maintenance and liability concerns, as well as for stream restoration.
