Summary

Lucie, Florida, serves as a vital flood risk reduction measure along Canal Main No-01, designed by USDA NRCS in 1981. This stone core structure stands at a height of 17 feet, with a hydraulic height of 13 feet and a length of 36 feet, providing a maximum storage capacity of 60 acre-feet. The primary purpose of this structure is flood risk reduction, with additional benefits for irrigation in the region.

Despite being classified as having a low hazard potential, Water Control Structure 2 still plays a crucial role in managing water levels and protecting the surrounding area from potential flooding events. The structure features an uncontrolled spillway type and outlet gates, with a maximum discharge capacity of 752 cubic feet per second. Although last inspected in 1994, the condition assessment remains ungraded, emphasizing the need for periodic evaluations to ensure the continued effectiveness and safety of this water control infrastructure.

With a moderate risk assessment score of 3, Water Control Structure 2 stands as a testament to effective water resource management in Florida. While not under state regulation or jurisdiction, this structure highlights the collaborative efforts between local government and the Natural Resources Conservation Service in safeguarding communities against the impacts of extreme weather events. As climate enthusiasts and water resource advocates, understanding and supporting the maintenance and upkeep of such critical infrastructure is essential for building resilience in the face of changing climate patterns.

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.
