Summary
This earth dam was completed in 1952 and serves the primary purpose of supplying water to the surrounding area. Situated on Belews Creek in the city of Grimes Crossroads, the dam has a hydraulic height of 14 feet and a structural height of 20 feet, with a length of 650 feet.
With a storage capacity of 300 acre-feet and a drainage area of 2112 acres, the Kernersville Water Supply Dam plays a crucial role in managing water resources in the region. Despite being classified as having a high hazard potential, the dam is currently in fair condition as of the last inspection in January 2021. The dam is regulated by the North Carolina Department of Environmental Quality's Dam Safety Program, ensuring that it meets all necessary safety standards for protecting the local community and environment.
Water resource and climate enthusiasts will appreciate the significance of the Kernersville Water Supply Dam in providing a reliable water supply for the area. Its strategic location on Belews Creek and ample storage capacity make it a key infrastructure asset for managing water resources and mitigating potential hazards. With proper regulatory oversight and maintenance, the dam continues to serve its essential function while safeguarding the surrounding community from potential risks.

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.
