Summary

Built in 1950, this private-owned Earth dam spans 7920 feet and reaches a height of 10 feet, with a storage capacity of 224 acre-feet. The dam primarily serves the purpose of recreation, offering a surface area of 40 acres for activities such as fishing, boating, and wildlife observation.

Despite its low hazard potential and fair condition assessment, Lake Legendre Dam is regulated and inspected by the South Carolina Department of Health and Environmental Control to ensure compliance with safety standards. The dam overlooks the TR-Prioleau Creek and boasts a spillway width of 0, with no locks or associated structures. The last inspection in December 2017 revealed a need for further monitoring and maintenance, highlighting the importance of ongoing care and oversight for the preservation of this water resource.

For water resource and climate enthusiasts, Lake Legendre Dam represents a unique opportunity to explore the intersection of human infrastructure and natural beauty. As a recreational hub in the Charleston District, the dam not only provides local residents and visitors with a picturesque setting for outdoor activities but also serves as a reminder of the importance of responsible dam management in the face of evolving environmental challenges. With its historical significance and potential for future development, Lake Legendre Dam is a captivating destination for those passionate about water conservation and sustainable land use practices.

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.
