Summary

Built in 1980, this earth dam stands at 35 feet high and serves primarily for tailings purposes. With a storage capacity of 7200 acre-feet and a surface area of 218 acres, Mosaic Csa Bf2 plays a crucial role in managing water resources in the area.

Despite its age, Mosaic Csa Bf2 has been maintained and regulated by the Florida Department of Environmental Protection, with state permitting, inspection, and enforcement procedures in place. The dam has a significant hazard potential and is classified as having a very high risk, emphasizing the importance of proper risk management measures. The structure's controlled spillway and uncontrolled outlet gates ensure water flow control and safety during high discharge events.

As a key component of water resource management in Hillsborough County, Florida, Mosaic Csa Bf2 highlights the intersection of infrastructure, climate, and environmental stewardship. Its presence along the Alafia River showcases the delicate balance between human development and natural ecosystems, underscoring the importance of sustainable practices in safeguarding our water resources for future generations.

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.
