Summary
Standing at a hydraulic height of 25 feet and a structural height of 27 feet, the dam spans 305 feet in length and has a storage capacity of 11 acre-feet. While the dam's condition assessment is currently listed as "Not Rated," its hazard potential is considered significant, emphasizing the importance of regular inspections and maintenance.
Despite not being regulated by the state, Riddle Dam does undergo periodic inspections, with the last recorded assessment dating back to June 2007. With a focus on recreation, the dam provides opportunities for water enthusiasts to enjoy its surroundings, offering a tranquil escape in the city of Newfound. However, the lack of recent data on risk assessment, emergency preparedness, and inundation maps highlights the need for continued monitoring and proactive measures to ensure the safety and longevity of this water resource for climate enthusiasts to enjoy for years to come.
As a significant feature in Congressional District 11, North Carolina, Riddle Dam serves as a vital recreational area while also posing potential risks due to its hazard potential. With its private ownership and limited state regulation, the dam's upkeep and safety fall squarely on the responsibility of its owners. As water resource and climate enthusiasts continue to explore and appreciate the beauty of Riddle Dam, it is crucial for all stakeholders to prioritize proper maintenance and risk management strategies to mitigate any potential hazards and ensure the safety of both visitors and the surrounding environment.

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.
