Summary

This wetland treatment system plays a crucial role in water resource management by effectively treating tailings and promoting water quality in the region. Designed by ARDAMAN & ASSOCIATES and completed in 1995, this Earth dam stands at 45 feet high with a hydraulic height of 40 feet, serving as a key component in the treatment process.

With a storage capacity of 3,400 acre-feet and a surface area of 75 acres, this wetland treatment system is regulated by the Florida Department of Environmental Protection (FDEP) and is subject to state permitting, inspection, and enforcement. The system is situated along the Alafia River and has a significant hazard potential, highlighting the importance of its proper maintenance and management. Despite not being rated for condition assessment, the system's risk assessment is moderate, indicating the need for ongoing monitoring and risk management measures to ensure its continued effectiveness for water quality improvement in the area.

Overall, the City of Lakeland Wetland Treatment System West stands as an essential asset in the region's water resource and climate resilience efforts. By effectively treating tailings and promoting water quality through its wetland treatment process, this Earth dam plays a critical role in safeguarding the environment and supporting sustainable water management practices in 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.
