Summary
This earth dam, designed by BCI Engineers & Scientists, was completed in 2002 and stands at a height of 30 feet with a hydraulic height of 25 feet. With a storage capacity of 10,000 acre-feet and a surface area of 325 acres, this dam serves the primary purpose of tailings management.
The dam has a controlled spillway with a width of 34 feet and a maximum discharge of 20 cubic feet per second. It has a significant hazard potential and is classified as having a very high risk, making it a crucial structure for water resource and climate enthusiasts to monitor. Although the condition assessment is currently not rated, the dam is regulated, permitted, inspected, and enforced by the Florida Department of Environmental Protection, ensuring that safety measures are in place.
Given its location and significance, W2 Mix Area South Pasture represents a key component of water management in the region. With its impressive storage capacity and risk profile, this structure serves as a focal point for understanding the intersection of water resource management and climate resilience in the area.

Dam Data Reference
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.
