Summary
Built in 1906, this concrete structure stands at a height of 34 feet and stretches 1397 feet in length. With a maximum storage capacity of 2250 acre-feet and a drainage area of 7600 acres, Milford plays a crucial role in both hydroelectric power generation and recreational activities in the region.
Managed by the Federal Energy Regulatory Commission, Milford has a low hazard potential and is subject to regular inspections every three years. The dam features an uncontrolled spillway with a width of 945 feet, ensuring the safe release of excess water during high flow events. Despite its age, Milford continues to operate efficiently, supporting the local community while maintaining a moderate risk assessment rating.
For water resource and climate enthusiasts, Milford serves as a fascinating example of sustainable infrastructure that combines energy production with environmental stewardship. Its presence on the Penobscot River not only contributes to the region's power grid but also provides a recreational haven for residents and visitors alike. As discussions around climate change and water resource management grow, Milford stands as a testament to the importance of innovative solutions in meeting the challenges of the future.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
