Summary
Completed in 1953, this private-owned earth dam stands at a height of 13 feet with a structural height of 6 feet and a length of 52 feet. With a storage capacity of 1280 acre-feet and a normal storage of 900 acre-feet, it plays a vital role in managing water levels and protecting the surrounding areas from potential flooding.
Situated along the South Relief Canal, this structure is regulated and inspected by the state, ensuring its functionality and safety. Despite having a low hazard potential and being in a not-rated condition assessment, the South Relief Structure remains a key asset in water resource management in Indian River County. Its strategic location and design contribute to its effectiveness in mitigating flood risks and supporting irrigation needs in the region.
Managed by the Jacksonville District of the US Army Corps of Engineers, the South Relief Structure exemplifies the importance of sustainable water infrastructure in addressing climate challenges. With its primary purpose of flood risk reduction and its role in supporting irrigation, this earth dam stands as a testament to the collaborative efforts between private owners and state agencies in safeguarding water resources and communities against environmental threats.

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.
