Summary

With a dam height of 45 feet and a storage capacity of 2500 acre-feet, this concrete gravity dam serves as a key structure for water resource management and energy production in the region. Operated by the Federal Energy Regulatory Commission, the dam has a low hazard potential and moderate risk assessment, making it a vital asset for sustainable water and climate management.

In addition to its primary purpose of hydroelectric power generation, Gaston Shoals Middle also provides flood control and recreation opportunities for the surrounding area. With a drainage area of 1300 square miles and a maximum discharge capacity of 54,000 cubic feet per second, the dam plays a crucial role in regulating water flow and protecting downstream communities from potential flooding events. Despite its age, the dam remains in good condition and is inspected regularly to ensure its continued safety and functionality.

Overall, Gaston Shoals Middle is a significant water resource infrastructure with historical importance and ongoing relevance for water resource and climate enthusiasts. Its strategic location, structural design, and operational efficiency make it a valuable asset for sustainable water management and environmental stewardship in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
