Summary
Built in 1970 by the USDA NRCS, this earth dam stands at a height of 20 feet and has a length of 250 feet, creating a storage capacity of 73 acre-feet for the nearby TR-BLACK CREEK. The primary purpose of this dam is for recreation, providing a surface area of 8 acres for outdoor activities.
Despite its low hazard potential, Middendorf Pond Dam is currently in poor condition according to a 2017 assessment. The dam has an uncontrolled spillway and outlet gates, with a moderate risk rating of 3. Regular inspections are conducted by the South Carolina Department of Health and Environmental Control to ensure the safety and integrity of the structure. While the dam provides recreational opportunities, its maintenance and potential risk factors should be closely monitored by relevant regulatory agencies to prevent any potential hazards to the surrounding community and environment.
As a designated state-regulated dam, Middendorf Pond Dam falls under the jurisdiction of SC DHEC and undergoes inspections every five years. With its location in a beautiful natural setting, water resource and climate enthusiasts can appreciate the importance of maintaining and monitoring this dam to ensure its continued safe operation for both recreational and environmental purposes in the future.

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.
