Summary
The earth dam stands at a height of 12 feet and spans a length of 550 feet, creating a storage capacity of 252 acre-feet. Despite its modest size, the dam poses a high hazard potential and has been assessed to be in poor condition as of January 2019.
The dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC), with state permitting, inspection, and enforcement all in place to ensure compliance with safety standards. The dam's location on Tinker Creek adds to its significance for water resource and climate enthusiasts, as it contributes to the overall hydrology of the area. However, with its current condition and hazard potential, there is a need for ongoing monitoring and potential risk management measures to address any safety concerns.
With its proximity to the city of Barnwell and its association with recreational activities, Mixon Pond Dam serves as a focal point for both local residents and visitors. The dam's history, design, and operational details provide valuable insights for those interested in water resource management and climate impacts on infrastructure. As efforts continue to maintain the dam's safety and functionality, it remains a key component of the region's water resources landscape.

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.
