Summary
With a dam height of 19 feet and a storage capacity of 120 acre-feet, Belfort plays a crucial role in managing the region's water resources. The dam's concrete construction and controlled spillway system ensure its structural integrity and efficient operation.
Managed by the Federal Energy Regulatory Commission, Belfort has a low hazard potential and a very high risk assessment rating, highlighting the importance of regular inspections and maintenance. Despite not being state regulated, the dam's impact on the surrounding environment and waterways is closely monitored. With a drainage area of 252 square miles and a maximum discharge capacity of 10,100 cubic feet per second, Belfort is a key player in the region's water management infrastructure.
With its historic significance and environmental impact, Belfort stands as a testament to the intersection of water resources, climate conservation, and sustainable energy production. As the region's water resource and climate enthusiasts continue to appreciate and monitor the dam's operations, Belfort remains a symbol of responsible hydroelectric power generation and water management practices.

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.
