Summary

The earth dam stands at a height of 100 feet and has a hydraulic height of 95 feet, with a structural height of 105 feet. It has a capacity for storing 640 acre-feet of water, with a normal storage level of 448 acre-feet. The dam spans a length of 5650 feet and covers a surface area of 32 acres, with a maximum discharge capacity of 110 cubic feet per second.

The dam is situated on an unnamed pond and is regulated by the state of Florida, with permitting, inspection, and enforcement measures in place. It is classified as having a significant hazard potential and a very high risk level. Despite being in operation, the dam's condition assessment is listed as "Not Rated," and there is no information available on when it was completed or when it was last inspected. The spillway type for Mulberry S (2) is controlled, with a spillway width of 64 feet, and there are no associated locks or gates.

Overall, Mulberry S (2) serves as a vital structure for tailings storage in the area, with a capacity to manage water flow and storage efficiently. As a significant dam with a very high risk level, it is crucial for proper monitoring and maintenance to ensure the safety and integrity of the structure. With its location in a state regulated area and its important role in water resource management, Mulberry S (2) stands as a key feature in the landscape of Polk County, Florida.

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.
