Summary
Completed in 1969, this earth dam stands at a height of 16 feet and spans 400 feet in length. With a storage capacity of 255 acre-feet, the dam serves as a recreational hub for visitors to enjoy activities such as fishing, boating, and picnicking in the surrounding area.
Managed by the South Carolina Department of Health and Environmental Control, the dam is subject to regular inspections and enforcement to ensure its safety and regulatory compliance. With a significant hazard potential, the dam's condition is currently not rated, highlighting the need for ongoing risk assessment and management measures. Although the dam has not been modified in recent years, its emergency action plan status and inundation maps are yet to be updated, indicating areas for improvement in emergency preparedness.
Given its importance for both recreation and water resource management, Evergreen Timberland Dam plays a crucial role in the local ecosystem and community. With its picturesque location on Threemile Branch, the dam provides a serene escape for outdoor enthusiasts and serves as a reminder of the delicate balance between human recreation and environmental stewardship in our changing climate.

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.
