Summary
Standing at a height of 7 feet and with a length of 290 feet, this dam holds a storage capacity of 75 acre-feet, with a normal storage level of 30 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2017 was rated as poor, indicating a need for maintenance and repairs.
Managed by the South Carolina Department of Health and Environmental Control (SC DHEC), Lees No3 Pond Dam is state-regulated, with required inspections, permitting, and enforcement measures in place. The dam spans the TR-BUCKHEAD BRANCH river/stream and falls under the jurisdiction of the Charleston District of the US Army Corps of Engineers. With a moderate risk assessment level of 3, it is crucial for stakeholders and authorities to address the dam's poor condition and implement necessary risk management measures to ensure the safety and integrity of the structure.
As an essential recreational resource in the area, Lees No3 Pond Dam serves as a popular spot for water enthusiasts and nature lovers. However, with its outdated infrastructure and maintenance issues, there is a pressing need for attention and investment to preserve this historical dam and its surrounding ecosystem. By prioritizing safety and environmental stewardship, stakeholders can work towards ensuring the long-term sustainability and enjoyment of this valuable water resource.

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.
