Summary

Completed in 1966, this earth dam stands at a height of 37 feet and stretches 365 feet in length, creating a reservoir with a maximum storage capacity of 106 acre-feet. While its primary purpose is for recreation, the dam is also vital for flood control and water supply management in the region.

Situated on the TR-South Saluda River, Lake Gintomo Dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC) and undergoes regular inspections to ensure its structural integrity. Despite being classified as having a high hazard potential, the dam is currently in fair condition. With a surface area of 7 acres, the reservoir provides a picturesque setting for outdoor activities and serves as a strategic water resource for the local community.

Managed by a private entity, Lake Gintomo Dam plays a significant role in the environmental and recreational landscape of Greenville. Its earth construction, stone core, and soil foundation contribute to its durability and functionality. As water resource and climate enthusiasts, the dam serves as a prime example of how private ownership can effectively steward and utilize natural resources for multiple benefits, including recreation, flood control, and water supply management.

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.
