Summary

The dam, completed in 1964, is an earth structure standing at 25 feet high and stretching 1375 feet in length. With a storage capacity of 51 acre-feet and a surface area of 113 acres, the lake provides a tranquil setting for water activities such as fishing and boating.

Managed by the state with permitting, inspection, and enforcement in place, Lake Joy has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The surrounding area, known as TR-MARSHALL SWAMP, contributes to the drainage area of the reservoir. Despite not having a spillway or locks, the reservoir is well-maintained and meets regulatory guidelines.

For water resource and climate enthusiasts, Lake Joy offers a picturesque retreat in the heart of Florida. Its serene waters, surrounded by natural beauty, provide a haven for outdoor enthusiasts seeking a tranquil escape. With its low hazard potential and state-regulated management, Lake Joy stands as a sustainable and safe water resource for the community to enjoy for years to come.

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.
