Summary
Constructed in 1921, this gravity dam stands at a height of 30.3 feet and serves the primary purpose of generating hydroelectric power. With a maximum storage capacity of 3,510 acre-feet and a normal storage capacity of the same, Halifax plays a crucial role in harnessing the energy potential of the Banister River.
Managed by the Federal Energy Regulatory Commission, Halifax has a significant hazard potential and is classified as having a very high risk factor. With a spillway width of 293 feet and a maximum discharge of 40,000 cubic feet per second, the dam is equipped with 11 flap outlet gates. Despite its age, the condition assessment of Halifax is not available, highlighting the need for continued monitoring and maintenance to ensure its structural integrity and safety.
As an integral part of the water resource infrastructure in Halifax, this historic dam serves as a reminder of the importance of sustainable energy generation and the preservation of our natural resources. Climate enthusiasts and water resource advocates alike can appreciate the role that Halifax plays in providing clean energy while also recognizing the need for ongoing risk management measures to safeguard the surrounding community and ecosystem.

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.
