Summary

Built in 1952, this dam stands at a height of 37 feet and has a length of 275 feet, creating a storage capacity of 106 acre-feet for the surrounding area. The dam is situated on the TR-SPRIGG CREEK and is regulated by the South Carolina Department of Health and Environmental Control (DHEC).

With a hazard potential rated as high and a fair condition assessment as of March 2021, Lake Mollirene Dam is regularly inspected every two years to ensure its structural integrity and safety. The dam has a normal storage capacity of 77 acre-feet and covers a surface area of 6 acres, providing a picturesque setting for outdoor activities such as fishing, boating, and picnicking. Despite its private ownership, the dam plays a significant role in the local community's recreational opportunities and water resource management.

For water resource and climate enthusiasts, Lake Mollirene Dam serves as a vital infrastructure for both recreation and environmental regulation in the Greenville area. Its presence on the TR-SPRIGG CREEK not only enhances the region's water storage capacity but also contributes to the overall ecosystem health. As efforts continue to maintain and monitor the dam's safety, it remains a key component of the local landscape, offering a serene retreat for outdoor enthusiasts while ensuring the responsible management of water resources in South Carolina.

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.
