Summary

The dam, designed for recreation purposes, stands at a height of 12 feet and stretches over a length of 5091 feet, creating a surface area of 131 acres. Situated on an unnamed pond, Mem1 is regulated by the Florida Department of Environmental Protection (FDEP) and adheres to state permitting, inspection, and enforcement protocols.

With a storage capacity of 2394 acre-feet, Mem1 poses an undetermined hazard potential and currently holds a condition assessment of "Not Rated." The dam's emergency action plan status, risk assessment, and management measures remain unaddressed, highlighting potential areas for improvement in emergency preparedness. Despite lacking specific details on modification history, inspection frequency, and contact information, Mem1's significance lies in its role as a recreational structure within the Jacksonville District of Florida.

For water resource and climate enthusiasts, Mem1 presents an intriguing case study of a privately owned dam in a state-regulated environment. The dam's location, purpose, and design offer valuable insights into the intersection of human activity with natural water systems. As efforts continue to assess and manage potential risks associated with dams like Mem1, the importance of proactive monitoring and emergency planning becomes increasingly apparent in safeguarding water resources and communities from potential hazards.

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.
