Summary
Built in 1911, this gravity dam stands at a height of 37 feet and has a hydraulic height of 31.4 feet, serving as a vital source of energy generation in the region. With a maximum discharge capacity of 65,000 cubic feet per second and a storage capacity of 400 acre-feet, Marshall plays a crucial role in water resource management and climate resilience efforts.
Managed by the Federal Energy Regulatory Commission, Marshall is inspected regularly to ensure its structural integrity and operational efficiency. The dam's low hazard potential and moderate risk assessment make it a reliable and safe infrastructure for the surrounding communities. With its uncontrolled spillway and other controlled outlet gates, Marshall is equipped to handle potential emergencies and mitigate any risks associated with its operation.
As a historic landmark in Madison, North Carolina, Marshall not only provides hydroelectric power but also contributes to flood control and water supply management in the region. Its presence on the French Broad River underscores the intersection of water resources and climate considerations, making it a significant asset for enthusiasts and stakeholders interested in sustainable infrastructure development and environmental stewardship.

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.
