Mosaic Csa F2c dam
Mosaic Csa F2c
Located in Hillsborough, Florida, the Mosaic Csa F2c dam stands as a crucial structure for managing water resources in the region. Completed in 1994, this earth dam primarily serves the purpose of storing tailings, with a maximum storage capacity of 34,500 acre-feet and a surface area of 650 acres. The dam's significant hazard potential and high risk assessment highlight the importance of effective risk management and regular inspections to ensure its structural integrity and safety.
Managed by the private entity Mosaic, the Mosaic Csa F2c dam is regulated by the Florida Department of Environmental Protection (FDEP) and undergoes state permitting, inspection, and enforcement processes. The dam, situated on Alderman Creek, is designed by ARDAMAN & ASSOCIATES and features an uncontrolled outlet gates system. With a structural height of 57 feet and a hydraulic height of 50 feet, the dam plays a vital role in flood control and water storage for the surrounding area.
The Mosaic Csa F2c dam, with its stone core and earth construction, represents a critical piece of infrastructure in the water resource management system of Hillsborough County. With a history of modifications and a lack of current condition assessment, the dam's risk profile underscores the need for ongoing monitoring and maintenance to safeguard against potential hazards and ensure the sustainability of water resources in the region for years to come.
Dam data reference
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.
- 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.
- 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.
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, environmental 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.

About Mosaic Csa F2c
Where does the data for Mosaic Csa F2c come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
