Summary

Managed by the Florida Department of Environmental Protection, this dam stands at 30 feet high with a storage capacity of 10,000 acre-feet and a surface area of 370 acres. With a controlled spillway and a significant hazard potential rating, this dam plays a crucial role in water resource management in the region.

The dam's design, construction, inspection, and enforcement are all overseen by state regulatory agencies, ensuring its safety and compliance with regulations. Despite being classified as "Not Rated" in terms of condition assessment, the W3 Mix Area South Pasture dam poses a very high risk level (1) according to the risk assessment. Emergency action plans and risk management measures for this dam are not specified, raising concerns for potential hazards and the need for proactive monitoring and maintenance to mitigate risks and protect the surrounding environment.

As water resource and climate enthusiasts, understanding the intricacies of dam infrastructure like the W3 Mix Area South Pasture is vital for effective water management and climate resilience efforts. By staying informed about the condition, risk level, and regulatory oversight of dams like this one, we can advocate for sustainable practices and policies to safeguard our water resources and communities in the face of changing climate conditions.

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.
