Summary
Completed in 1952, this structure stands at 17 feet tall with a hydraulic height of 12 feet and a length of 175 feet. With a storage capacity of 300 acre-feet and a drainage area of 1.5 square miles, G-87 plays a crucial role in managing water levels and mitigating potential flooding in the region.
Despite being classified as having a low hazard potential, G-87 is considered to have a very high risk due to its age and condition assessment not being rated. The dam's spillway type is controlled with a width of 7 feet, and it features stone core types supported by rock and soil foundations. While the last inspection date dates back to July 1905, the structure undergoes state permitting, inspection, and enforcement to ensure its functionality and safety. With its primary purpose being flood risk reduction, G-87 serves as a vital infrastructure in safeguarding Sunshine Ranches and the surrounding areas from potential water-related disasters.
For water resource and climate enthusiasts, G-87 presents an intriguing case study of a historic earth dam in Florida. Its location along the C-11S Canal, under the regulatory oversight of FDEP, highlights the importance of effective water management and infrastructure maintenance in the face of increasing climate challenges. As discussions around risk management and resilience continue to evolve, G-87 serves as a reminder of the critical role that dams play in protecting communities and natural habitats from the impacts of extreme weather events and rising water levels.

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.
