Summary

With a height of 100 feet and a hydraulic height of 95 feet, this dam serves primarily for tailings storage purposes. The dam has a storage capacity of 1152 acre-feet, with a normal storage level of 806 acre-feet and a surface area of 58 acres.

Despite its critical role in water resource management, Piney Point(5) poses a significant hazard potential, with a very high risk assessment rating of 1. While the dam's condition has not been rated and inspections have not been conducted, it is regulated, permitted, and inspected by the state of Florida. The dam features a controlled spillway with a width of 64 feet, designed to manage a maximum discharge of 110 cubic feet per second.

Climate and water resource enthusiasts should take note of Piney Point(5) due to its location in a high-risk area and its importance in managing water resources. With a focus on tailings storage, this dam plays a crucial role in the local ecosystem and requires careful monitoring and management to ensure the safety of surrounding communities and the environment.

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.
