Summary
Spanning a length of 1650 feet and standing at a height of 15 feet, this dam serves a primary purpose that is designated as "Other." With a storage capacity of 300 acre-feet and a surface area of 50 acres, the dam is situated on Crooked Creek and is regulated by the South Carolina Department of Health and Environmental Control.
Despite being classified as having a low hazard potential, the dam's condition assessment is labeled as poor as of November 2017. The inspection frequency for McCall Millpond Dam is every 5 years, with the last inspection conducted on November 7, 2017. The risk assessment for the dam is moderate, indicating a level 3 risk. The dam currently does not have an Emergency Action Plan (EAP) in place, and it is not owned or funded by any federal agency.
For water resource and climate enthusiasts, McCall Millpond Dam presents an interesting case study in dam infrastructure management and maintenance. With its historical significance dating back over two centuries, the dam's condition assessment and risk level serve as important factors to consider for the continued safe operation of the structure and the protection of downstream communities and ecosystems. Additionally, the dam's location on Crooked Creek highlights the interconnectedness of water resources and the importance of effective regulatory oversight in ensuring the safety and sustainability of our water infrastructure.

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.
