Summary
Owned privately, this earth dam serves multiple purposes, including recreation and other activities. With a maximum storage capacity of 690 acre-feet and a normal storage of 500 acre-feet, Windsor Lake Dam covers a surface area of 59 acres, offering a picturesque spot for water resource and climate enthusiasts.
Despite its significance, Windsor Lake Dam poses a high hazard potential and has been assessed as unsatisfactory in condition. The last inspection date recorded was in June 2018, indicating the need for regular monitoring and maintenance. With state regulation and inspection in place, the dam remains under the jurisdiction of the South Carolina DHEC, ensuring compliance with safety standards and enforcement measures.
As an essential component of the Savannah District, Windsor Lake Dam plays a crucial role in managing water resources and providing recreational opportunities in Richland, South Carolina. With its historical significance dating back to the 1960s, this structure stands as a testament to engineering marvels and the need for continual oversight to safeguard against potential risks and ensure the safety of surrounding communities and ecosystems.

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.
