Summary
Completed in 1960, this earth dam boasts a height of 50 feet and holds a normal storage capacity of 33,500 acre-feet. With a surface area of 2061.1 acres and a storage capacity of 59,659 acre-feet, Lake Robinson Dam plays a crucial role in water resource management in the region.
Owned by a public utility and regulated by the South Carolina Department of Health and Environmental Control (DHEC), Lake Robinson Dam is subject to regular inspections to ensure its safety and functionality. The dam's hazard potential is classified as high, but its condition assessment as of December 2019 was deemed satisfactory. With its strategic location on Black Creek and its role in providing hydroelectric power, Lake Robinson Dam represents a significant infrastructure asset in the state's water management system.
Visitors to Lake Robinson Dam can enjoy recreational activities such as boating and fishing while appreciating the engineering marvel that enables water storage and power generation. As a cornerstone of water resource management in Darlington County, this dam exemplifies the intersection of human ingenuity and environmental stewardship in harnessing the power of water for multiple beneficial uses.

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.
