Summary
Built in 1944, this earth dam stands at a hydraulic height of 16 feet and a structural height of 18 feet, with a length of 570 feet. The dam has a maximum storage capacity of 108 acre-feet and a normal storage of 90 acre-feet, covering a surface area of 12 acres.
Despite being privately owned, Sizemore Lake Dam is subject to state inspection, which last took place in October 2014 and deemed the structure to be in satisfactory condition with low hazard potential. The dam has not been modified in recent years and does not pose a significant risk to the surrounding area. While it is not regulated by the state, the dam meets guidelines for emergency action plans, although specific details on preparedness and risk management measures are not provided in the data.
Water resource and climate enthusiasts may find Sizemore Lake Dam to be an interesting case study due to its recreational purpose, historical significance, and relatively low risk profile. The dam's location on the Rocky River in Randolph County, North Carolina, offers opportunities for studying local water resources and their management in a private ownership context. Despite its age, the dam continues to serve its intended purpose effectively, highlighting the importance of regular inspections and maintenance for ensuring the safety and functionality of such structures in the face of changing climate conditions.

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.
