Summary

The dam stands at an impressive height of 150 feet and stretches 1800 feet in length, providing a maximum storage capacity of 955,586 acre-feet. This dam serves multiple purposes, including hydroelectric power generation, recreation, and water supply for the surrounding areas, making it a vital resource for the community.

Managed by the Federal Energy Regulatory Commission, Little River Dam is a key player in the region's water resource management, with a high hazard potential due to its size and location. Despite its age, the dam's condition assessment is not available, highlighting the need for ongoing monitoring and maintenance to ensure its continued safety and effectiveness. With its scenic location along the Little River and its important role in providing renewable energy and water for the area, Little River Dam is a significant asset worth exploring and preserving for future generations of water resource and climate enthusiasts.

As a public utility owned structure, Little River Dam is a cornerstone of the Oconee region in South Carolina, offering a blend of environmental, recreational, and economic benefits. The dam's primary purpose of hydroelectric power generation underscores its commitment to sustainable energy practices, while also providing opportunities for outdoor activities and water supply management. With its high risk assessment rating and historical significance, Little River Dam stands as a symbol of innovation and resilience in water resource management, making it a must-see destination for those passionate about protecting our planet's natural assets.

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.
