Summary
Constructed in 1925, this concrete dam serves a primary purpose of hydroelectric power generation along the Green River. Standing at a hydraulic height of 87 feet and a length of 665 feet, this dam plays a crucial role in water resource management in the region.
Managed by the local government and regulated by the NCDEQ Dam Safety Program, Turner Shoals Dam has a storage capacity of 16,530 acre-feet and a drainage area of 80,640 acres. With a maximum discharge capacity of 34,000 cubic feet per second, this dam presents a high hazard potential but is currently assessed to be in fair condition as of May 2017. Its surface area of 438 acres and normal storage capacity of 13,776 acre-feet make it a significant water resource for the surrounding area.
For water resource and climate enthusiasts, Turner Shoals Dam offers a blend of historical significance and vital hydroelectric infrastructure. With its impressive structure and important role in managing water resources along the Green River, this dam serves as a key landmark in Polk, North Carolina. The ongoing inspections and regulatory oversight ensure its continued operation and contribution to the local water supply and energy generation.

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.
