Summary

This earthen dam stands at a height of 33 feet and spans a length of 280 feet, with a storage capacity of 154 acre-feet. Situated on the TR-Jerry Creek, this dam is under state regulation by the South Carolina Department of Health and Environmental Control (DHEC), with regular inspections and enforcement to ensure its safety and compliance.

Despite being classified as having a high hazard potential, Oconee State Park Dam 1 is currently assessed to be in fair condition as of the last inspection in June 2019. The dam is equipped with outlet gates, but specific spillway details are not provided in the data. With a history of modifications unlisted, this dam continues to provide vital recreational opportunities while also serving as a vital component of water resource management in the region.

Water resource and climate enthusiasts interested in the Oconee State Park Dam 1 can appreciate its historical significance, engineering design, and ongoing maintenance efforts to ensure public safety and environmental protection. As an integral part of the Nashville District in South Carolina, this dam stands as a testament to the balance between human recreation and the preservation of natural resources in the region.

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.
