Summary
The dam, standing at a height of 25 feet and a length of 625 feet, holds a maximum storage capacity of 4,389 acre-feet of water from Juniper Creek. With a surface area of 207 acres, the dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC) and undergoes regular inspections to ensure public safety.
Despite its significant hazard potential and poor condition assessment, Eureka Lake Dam continues to be a popular spot for outdoor enthusiasts seeking water-based recreational activities. The dam's controlled spillway and high-risk designation underscore the importance of ongoing risk management measures to mitigate potential hazards. With a very high risk assessment rating, it is crucial for emergency action plans to be updated and aligned with current guidelines to address any unforeseen events that may impact the dam's structural integrity.
As climate change continues to pose challenges to water resources and infrastructure, the maintenance and monitoring of dams like Eureka Lake Dam become increasingly vital. With its historical significance and scenic surroundings, Eureka Lake Dam serves as a reminder of the importance of sustainable water management practices and the need for continuous investment in dam safety to protect both the environment and the community.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
