With a low hazard potential and moderate risk assessment, the dam is regulated by the Federal Energy Regulatory Commission and undergoes inspections every three years.
The dam features an uncontrolled spillway with a width of 90 feet and outlet gates for controlled release.

Despite its age, the Cataract - East Channel Dam has not had a recent condition assessment available and lacks an Emergency Action Plan update. However, it remains a vital piece of infrastructure for both energy production and water resource management in the region.
In the care of a private owner, this dam represents a blend of historical significance and modern functionality. With its strategic location on the Saco River and its role in the local ecosystem, the Cataract - East Channel Dam stands as a testament to the intersection of water resource management, climate adaptation, and renewable energy production in the state of Maine.
