Summary
With a hydraulic height of 17.4 feet and a structural height of 22 feet, the dam has a normal storage capacity of 10.56 acre-feet and a maximum storage capacity of 12 acre-feet. The dam spans 230 feet in length and covers a surface area of 1.3 acres, serving as a popular spot for outdoor activities in the Caswell County region.
Despite its recreational appeal, Jones Dam poses a high hazard potential due to its poor condition assessment. The dam has been inspected and regulated by the North Carolina Department of Environmental Quality, Dam Safety Program, with the last inspection conducted in January 2021. With a hazard potential rating of high, it is crucial for the dam owners and regulatory agencies to prioritize maintenance and emergency preparedness to ensure the safety of downstream communities and the surrounding environment.
Given its significance in the S. Fork Rattlesnake Creek-Tr watershed, Jones Dam plays a crucial role in water resource management in the region. The dam's location and structural specifications make it a key point of interest for water resource and climate enthusiasts seeking to understand the impact of dams on local ecosystems and the potential risks associated with aging infrastructure. As efforts continue to maintain and monitor Jones Dam, it serves as a reminder of the importance of sustainable water management practices in the face of a changing climate.

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.
