Summary
Completed in 1962, this earth dam stands at a height of 30 feet and spans a length of 1475 feet. With a storage capacity of 383 acre-feet, the dam encompasses a surface area of 21 acres and is situated on the TR-South Fork Edisto River.
Despite its low hazard potential, the dam is currently assessed to be in poor condition as of the last inspection in December 2017. The South Carolina Department of Health and Environmental Control (DHEC) is the regulatory agency responsible for overseeing the dam's state-regulated operations, inspections, and enforcement. While it is state-jurisdictional and permitted, the dam's condition warrants attention to ensure the safety and reliability of its structure for the surrounding community and water resources.
As a notable feature in the Savannah District, Mason Motes Pond Dam stands as a testament to the intersection of water resource management and climate considerations. With its historical significance and role in supporting irrigation activities, the dam serves as a valuable asset that requires ongoing maintenance and monitoring to uphold its functionality and safety standards in the face of evolving environmental challenges.

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.
