Summary
With a height of 35 feet and a length of 390 feet, this dam serves as a Fish and Wildlife Pond, providing essential habitat for aquatic life in the area. The dam has a storage capacity of 132 acre-feet, with a normal storage level of 105 acre-feet and a surface area of 8 acres.
Despite being classified as having a low hazard potential, the dam's condition assessment in 2017 rated as poor, indicating a need for maintenance and potential repairs. The dam's risk assessment is moderate, highlighting the importance of regular inspections and risk management measures to ensure the safety and integrity of the structure. The South Carolina Department of Health and Environmental Control regulates the dam, overseeing its permitting, inspection, and enforcement processes.
For water resource and climate enthusiasts, Edward Weisiger Dam offers a fascinating insight into the intersection of human infrastructure and natural ecosystems. As a vital component of the local environment, this dam plays a crucial role in sustaining wildlife populations and maintaining ecological balance in the region. Monitoring and maintaining the dam's condition are essential to ensure its continued functionality and minimize any potential risks to the surrounding community and environment.

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.
