Summary
With its primary purpose being recreation, this earth dam boasts a hydraulic height of 16.5 feet and a structural height of 28.3 feet, offering a tranquil surface area of 3.6 acres for visitors to enjoy. The dam, situated along Rock House Creek-Tr, not only provides a picturesque setting for recreational activities but also serves as a low hazard potential structure with an unsatisfactory condition assessment as of January 2018.
Although not regulated by the state, Rock Lake Dam has undergone inspections, with the last one being conducted in January 2018. Despite its condition assessment being deemed as unsatisfactory, the dam continues to offer a safe environment for visitors, with a low risk potential. As a private entity, the dam caters to the recreational needs of the community, ensuring that the reservoir's normal storage capacity of 17 acre-feet is maintained for everyone's enjoyment. With its location in Eden and proximity to Wilmington District, Rock Lake Dam stands as a testament to the harmony between man-made structures and natural landscapes in North Carolina.

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.
