Summary
The dam stands at a structural height of 14 feet with a hydraulic height of 8 feet and a length of 300 feet, impounding the waters of Shallotte Creek-Os. Its storage capacity reaches 61 acre-feet, providing a serene setting for outdoor activities in the Brunswick County area.
Despite being privately owned, the dam is subject to regular state inspections to ensure its safety and compliance with regulations. With a low hazard potential and a condition assessment of "Not Rated," the dam has not been modified in recent years and remains a reliable structure for water resource management and recreation. The last inspection in 2009 deemed it safe, further highlighting its importance in maintaining water levels and enhancing the surrounding environment.
Under the jurisdiction of the Wilmington District, Hewitt Lake Dam plays a vital role in the local ecosystem, offering a peaceful retreat for visitors and contributing to the overall water resource management in the region. Its presence along Shallotte Creek-Os serves as a reminder of the delicate balance between human enjoyment and environmental conservation, showcasing the intersection of water resources and climate dynamics in a picturesque setting.

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.
