Summary

With a hydraulic height of 14 feet and a structural height of 16 feet, this earth-type dam spans 660 feet and boasts a storage capacity of 55 acre-feet. The dam's normal storage capacity reaches 45 acre-feet, ensuring water availability for agricultural needs in the surrounding Rock Ridge area.

Maintained and regulated by the North Carolina Department of Environmental Quality's Dam Safety Program, Hendricks Lake Dam is subject to regular inspections to ensure its fair condition and significant hazard potential are managed effectively. The dam's last inspection in January 2019 revealed a fair condition assessment, with an inspection frequency of every two years. Despite its designation as having a significant hazard potential, the dam remains a crucial asset for irrigation and recreation purposes, with a maximum discharge capacity of 208 cubic feet per second and a surface area of 9 acres. Water resource and climate enthusiasts can appreciate the engineering marvel of Hendricks Lake Dam and its role in sustaining water resources for the local community.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
