About this dam

Mosaic Csa Bf4

Mosaic Csa Bf4, also known as Mobil Big Four Bf4, is a privately owned earth dam located in Bradley Junction, Florida. Completed in 1991, this dam serves the primary purpose of managing tailings and has a significant hazard potential, with a very high risk assessment rating. The dam stands at a height of 40 feet, with a hydraulic height of 35 feet and a structural height of 42 feet, holding a maximum storage capacity of 17,500 acre-feet.

Situated along the Alafia River in Hillsborough County, Florida, Mosaic Csa Bf4 spans a length of 18,562 feet and covers a surface area of 438 acres. The dam features a controlled spillway with a width of 64 feet and has a maximum discharge of 320 cubic feet per second. Despite being state-regulated and subject to inspection, the dam's condition assessment is currently not rated, highlighting the need for ongoing monitoring and risk management measures to ensure its safety and integrity.

With its location in a high-risk area and its critical role in managing tailings, Mosaic Csa Bf4 serves as a vital water resource infrastructure in Florida. As climate change continues to impact the region, the importance of maintaining and enhancing the resilience of dams like Mosaic Csa Bf4 becomes increasingly apparent, underscoring the need for effective regulatory oversight and proactive risk management strategies to safeguard both the environment and surrounding communities.

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.

FAQ

About Mosaic Csa Bf4

Where does the data for Mosaic Csa Bf4 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.
