Summary

The earth dam stands at a height of 30 feet and spans 950 feet in length, holding a maximum storage capacity of 1490 acre-feet. However, recent inspections have revealed a poor condition assessment and a high hazard potential, raising concerns about its structural integrity and safety.

Despite being privately owned, the dam is regulated by the state of Florida, with permits, inspections, and enforcement mechanisms in place to ensure compliance with safety standards. The dam's location on TR-Black Creek and its proximity to the city of Lake Asbury highlight its importance in protecting water resources and mitigating flood risks in the region. With its significant storage capacity and surface area of 62 acres, the dam plays a crucial role in managing water levels and supporting various recreational activities for local residents and visitors.

As water resource and climate enthusiasts monitor Lake Asbury South Dam, attention is drawn to the need for ongoing maintenance and potential risk management measures to address its current poor condition assessment. With a high hazard potential and a history of modifications, the dam's safety and resilience are of utmost importance to ensure the protection of the surrounding community and the sustainability of its recreational and environmental benefits.

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.
