Summary

This earth dam stands 105 feet tall and spans 4858 feet in length, with a storage capacity of 640 acre-feet and a surface area of 32 acres. The dam serves a primary purpose of tailings storage and is regulated by the state of Florida.

Despite its significant hazard potential and very high risk assessment rating, Mulberry (3) has not been rated for its condition assessment. The dam features a controlled spillway with a width of 64 feet and a maximum discharge capacity of 110 cubic feet per second. While there is no information available on the last inspection date or inspection frequency, the dam is equipped with emergency action plans and inundation maps to mitigate risks associated with its operation.

Water resource and climate enthusiasts will find Mulberry (3) an intriguing structure to study, given its location on a tributary of the Alafia River and its critical role in tailings storage. With its unique design features and high-risk profile, this dam presents a compelling case for further research and monitoring to ensure its safety and environmental impact are properly managed in the face of changing climate conditions.

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.
