Mcgirt's Millpond Dam Reservoir Report

Last Updated: December 6, 2025

Mcgirt's Millpond Dam in South Carolina stands as a testament to early 20th-century engineering, completed in 1900 with a primary purpose of providing recreational opportunities for visitors.

Summary

The earth dam, supported by a stone core and resting on a soil foundation, reaches a height of 10 feet and spans a length of 535 feet along the McGrits Creek. With a storage capacity of 272 acre-feet, the dam covers a surface area of 40 acres and is regulated by the South Carolina Department of Health and Environmental Control (DHEC).

Despite its fair condition assessment as of March 2020, the dam poses a significant hazard potential and undergoes inspections every three years to ensure its structural integrity. While the dam lacks a spillway and outlet gates, its associated structures are minimal, with no locks present. The dam's emergency action plan (EAP) was last revised in May 2013, and the risk assessment and management measures for the site remain unspecified. Located in Lee County, South Carolina, Mcgirt's Millpond Dam serves as a historical landmark and recreational destination, attracting water resource and climate enthusiasts alike to explore its scenic surroundings and engineering marvels.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
