Summary
Built in 1973, this earth and gravity dam on Stewarts Creek serves as a crucial water supply source for the region, with a storage capacity of 17,000 acre-feet and a surface area of 327 acres. The dam stands at a structural height of 60 feet and has a hydraulic height of 49 feet, providing essential water management capabilities for the area.
Despite its significant role in water supply, Twitty Dam poses a high hazard potential due to its condition assessment rating of "Fair." Regular inspections and enforcement measures by the North Carolina Department of Environmental Quality's Dam Safety Program ensure its safety and compliance with regulations. The dam's emergency action plan is updated periodically to meet guidelines, although specific risk assessment and management measures are yet to be detailed.
With its strategic location and critical role in water management, Twitty Dam stands as a vital asset for Union County, North Carolina. Climate and water resource enthusiasts can appreciate the dam's importance in ensuring water supply reliability and its ongoing efforts to maintain safety and compliance with regulatory standards. As a key piece of infrastructure in the region, Twitty Dam continues to play a crucial role in water resource management and climate resilience efforts.

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.
