Summary

This wetland treatment system serves as a crucial component in the management of tailings, with a primary purpose of containment and treatment. The system boasts an impressive dam height of 25 feet and a hydraulic height of 20 feet, providing significant storage capacity of 6200 acre-feet and a surface area of 273 acres.

Situated along the Alafia River, this wetland treatment system plays a crucial role in maintaining water quality and regulating discharge, with a controlled spillway ensuring proper management of water flow. The system's significant hazard potential underscores the importance of its regular inspection and maintenance, with a very high risk assessment rating. Despite its condition being marked as "Not Rated," the City of Lakeland Wetland Treatment System Central remains a key asset in the region's water resource management efforts, contributing to the overall health and sustainability of Florida's waterways.

As a state-regulated and state-permitted facility, this wetland treatment system operates under the oversight of the Florida Department of Environmental Protection (FDEP), ensuring compliance with environmental regulations and standards. With its strategic location and impressive design features, the City of Lakeland Wetland Treatment System Central stands as a testament to responsible water resource management and the importance of infrastructure in supporting climate resilience and sustainability efforts in the region.

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.
