Summary
Built in 1978 by ARDAMAN & ASSOCIATES, this tailings dam stands at a height of 35 feet with a structural height of 38 feet and a hydraulic height of 30 feet. It has a storage capacity of 10,000 acre-feet, with a normal storage level of 8,640 acre-feet over a surface area of 288 acres. The dam serves the primary purpose of tailings containment, with a spillway width of 64 feet and a maximum discharge of 30 cubic feet per second.
The dam is regulated by the Florida Department of Environmental Protection (FDEP) and has a significant hazard potential due to its location and size. Although its condition assessment is currently marked as "Not Rated," the risk assessment indicates a very high level of risk (1). While the last inspection date was in 2006, the dam is subject to regular state permitting, inspection, and enforcement to ensure its safety and compliance with regulations. With its strategic location along the Myakka River, Wingate Creek Isa plays a crucial role in water resource management and climate adaptation efforts in the region.
Overall, Wingate Creek Isa stands as a key infrastructure for water management in the area, providing essential storage capacity and flood control along the Myakka River. With its controlled spillway and state-regulated operations, the dam serves as a critical component in mitigating potential risks and ensuring the safety of surrounding communities. Climate enthusiasts and water resource professionals alike can appreciate the intricate design and management of Wingate Creek Isa in safeguarding against environmental hazards and supporting sustainable water resource practices in Manatee, Florida.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
