Summary
The dam's purpose is to control the flow of water in an unnamed pond, providing storage of up to 4,395.21 acre-feet. Despite its importance in managing water resources, the condition assessment of Hil11 is currently listed as "Not Rated," leaving its hazard potential undetermined.
Operated under state jurisdiction by the Florida Department of Environmental Protection, Hil11 is subject to regular inspections, permitting, and enforcement measures to ensure its safety and compliance with regulations. The dam, completed at an unspecified date, spans 3,958 feet in length and covers a surface area of 23 acres. While the risk assessment and emergency preparedness details for Hil11 remain unclear, its location in Hillsborough County signifies its significance in the local water resource management infrastructure.
With its proximity to the Jacksonville District of the US Army Corps of Engineers and oversight by federal and state agencies, Hil11 plays a crucial role in water resource management in the area. The dam's association with tailings and its substantial storage capacity underscore its importance in maintaining water quality and quantity in the region. As water resource and climate enthusiasts, understanding the operations and condition of dams like Hil11 is essential for ensuring sustainable water management practices for the future.

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.
