Summary
This earth dam, completed in 1930, serves primarily for recreational purposes, offering a surface area of 6 acres and a maximum storage capacity of 80 acre-feet. Situated on the North Buffalo Creek-Tr, the dam stands at a hydraulic height of 19 feet and a structural height of 21 feet.
The dam is regulated by the North Carolina Department of Environmental Quality's Dam Safety Program, with inspections and enforcement measures in place to ensure public safety. Despite its fair condition assessment and high hazard potential, the dam has a history of meeting regulatory guidelines and preparing for emergencies, as evidenced by past emergency action plans. The area surrounding Benjamin Dam provides a picturesque setting for outdoor activities and serves as a vital water resource in Guilford County.
Water resource and climate enthusiasts can appreciate the historical significance and recreational value of Benjamin Dam, which has been a part of the landscape for over 90 years. With a drainage area of 166 square miles and a maximum discharge capacity of 115 cubic feet per second, the dam plays a crucial role in managing water flow in the region. As efforts continue to maintain and monitor its condition, Benjamin Dam remains a key feature in the local ecosystem, offering both enjoyment and vital water management functions for the community.

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.
