Summary

Completed in 1995, this Earth dam structure serves primarily for tailings purposes and is situated along the Alafia River. With a dam height of 15 feet and a hydraulic height of 10 feet, it offers a storage capacity of 1,000 acre-feet and a surface area of 76 acres.

This wetland treatment system plays a crucial role in managing water resources and maintaining environmental quality in the region. With a controlled spillway type and a maximum discharge rate of 20 cubic feet per second, it effectively controls water flow and helps mitigate flood risks. The dam's condition assessment is currently not rated, but it is considered to have a significant hazard potential, emphasizing the importance of regular inspections and maintenance to ensure its reliability and safety.

Despite its very high risk assessment rating, City of Lakeland Wetland Treatment System East stands as a vital infrastructure for water resource management in the area. As a state-regulated facility with enforcement, inspection, and permitting capabilities, it showcases a commitment to environmental stewardship and sustainable water management practices. Its strategic location and design make it a key component in safeguarding the surrounding ecosystem and enhancing water quality for both present and future generations.

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.
