Summary
With a hydraulic height of 22.5 feet and a structural height of 27.5 feet, the dam boasts a significant presence along Harmon Creek-Tr. Despite its low hazard potential, the dam has not been state-regulated or permitted, indicating a unique management approach that focuses on private ownership and inspection.
The dam's 233-foot length and storage capacity of 27.5 acre-feet make it a key feature in the local landscape, offering a surface area of 2.5 acres for recreational activities. While the dam's condition remains unrated as of the last inspection in December 2020, its design and construction reflect a commitment to safety and functionality. With no associated structures or outlet gates, Todd Lake Dam serves as a testament to the enduring appeal of water resources for both environmental and leisure purposes.
As climate change continues to impact water resources and infrastructure, Todd Lake Dam stands as a reminder of the need for proactive management and risk assessment. With its location in Yadkin County and close proximity to Wilmington District, the dam plays a vital role in the local ecosystem and community. As enthusiasts of water resources and climate resilience, Todd Lake Dam offers a compelling case study of private ownership in dam construction and maintenance, highlighting the intersection of recreation, safety, and environmental stewardship in a changing climate landscape.

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.
