Summary
Completed in 1965, this dam serves primarily for recreational purposes, with a storage capacity of 71 acre-feet and a surface area of 9 acres. The dam stands at 18 feet in height and spans 1000 feet in length, creating a picturesque pond for local residents and visitors to enjoy.
Despite its low hazard potential, Mixons Pond Dam is currently assessed to be in poor condition as of the last inspection in November 2017. The dam is regulated by the South Carolina Department of Health and Environmental Control (SC DHEC), with state oversight for permitting, inspection, and enforcement. While the dam has not undergone any significant modifications in recent years, its condition raises concerns about its long-term safety and stability.
Given the dam's importance for recreational activities and potential impacts on the local ecosystem, it is essential for stakeholders to address the maintenance and rehabilitation needs of Mixons Pond Dam. With proper risk assessment, management measures, and regular inspections, the dam can continue to provide a safe and enjoyable environment for water resource and climate enthusiasts in the region.

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.
