Summary
Built in 1978, this earth dam stands at a height of 36 feet and stretches over 6,100 feet in length, providing a storage capacity of 155 acre-feet. Despite its low hazard potential, the dam has not been rated for its current condition, and there is no information available on its inspection frequency or emergency action plan.
The primary purpose of Dredged Spoil Retention Area C is categorized as "Other," indicating its role in managing dredged spoil material and potentially serving additional functions beyond standard water resource management. The structure falls under state regulation, with permitting, inspection, and enforcement responsibilities clearly outlined. Its location in a private ownership setting highlights the importance of private entities in managing water resources and infrastructure in the region.
With a limited surface area of 4 acres and no designated drainage area, Dredged Spoil Retention Area C remains a unique water resource feature along the Alafia River. While its risk assessment and management measures are not specified in the available data, the structure's presence adds to the diverse landscape of water management infrastructure in Florida. Enthusiasts interested in water resource management and climate resilience in the region may find value in further exploring the role and significance of Dredged Spoil Retention Area C in the local water ecosystem.

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.
