Summary

Completed in 1961, this dam stands at a height of 24 feet and has a length of 14,400 feet, providing a storage capacity of 7,325 acre-feet. Situated on an unnamed pond, the dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment.

Despite being state-regulated and permitted, with regular inspections and enforcement, West Polk A-4 does not fall under the jurisdiction of any federal agency. Its structural height of 20 feet and hydraulic height of 24 feet ensure its efficacy in managing water flow and preventing debris accumulation. With a surface area of 102 acres and a drainage area of 0, this dam serves as a crucial component in the local water resource management system.

The dam's location in Polk County, Florida, underlines its importance in mitigating flooding and maintaining water quality in the region. With a conservative design and a history of effective performance since its construction, West Polk A-4 remains a key asset in the efforts to sustainably manage water resources and adapt to the challenges posed by climate change.

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.
