About this dam

Sfm5 Mosaic

Sfm5 Mosaic, located in Polk, Florida, is a privately owned dam with a primary purpose of storing tailings. This earth dam, with a height of 50 feet and a hydraulic height of 45 feet, was completed in 2005 and has a storage capacity of 44,000 acre-feet. The dam sits on the Peace River and is regulated by the Florida Department of Environmental Protection, with state jurisdiction, permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.

With a significant hazard potential and a very high risk assessment rating, Sfm5 Mosaic is monitored closely for any potential risks or issues. The dam has a controlled spillway with a width of 128 feet and a maximum discharge capacity of 80 cubic feet per second. Despite not having a condition assessment rating, the dam has not been modified since its completion, and its last inspection was conducted in January 2006. While the dam does not have an emergency action plan in place, it meets regulatory guidelines and has designated emergency contacts for any potential incidents.

Overall, Sfm5 Mosaic serves a vital role in water resource management in the area, providing storage for tailings and helping to regulate the flow of the Peace River. Its construction and regulation ensure the safety of the surrounding community and the environment, with state and federal agencies overseeing its operations and maintenance. As climate change continues to impact water resources, dams like Sfm5 Mosaic play a crucial role in managing water supply and mitigating potential risks associated with extreme weather events.

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 Sfm5 Mosaic

Where does the data for Sfm5 Mosaic 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.
