Summary
The dam, classified as an Earth type structure with a core made of stone and built on a soil foundation, spans a length of 2900 feet and reaches a height of 27 feet, offering a serene surface area of 5 acres for visitors to enjoy. Situated on the TR-Coronaca Creek, the dam holds a maximum storage capacity of 75 acre-feet, with a normal storage level of 50 acre-feet for recreational activities.
Despite its fair condition assessment, Oakbrook Memorial Dam poses a high hazard potential, prompting biennial inspections to ensure public safety. The dam features a controlled spillway, although no outlet gates or locks are present. In the event of an emergency, contact procedures are established, and risk assessments have designated the dam as having a very high risk level. The dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC), underscoring its compliance with state permitting, inspection, and enforcement protocols.
Enthusiasts of water resources and climate will find Oakbrook Memorial Dam a noteworthy site, offering a blend of recreational opportunities and structural significance. With its historical completion date and ongoing maintenance efforts, the dam serves as a vital component of the local landscape while prioritizing safety and risk management. As visitors immerse themselves in the tranquil surroundings of the dam, they are met with a reminder of the balance between human enjoyment and environmental stewardship in water resource management.

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.
