About this dam

Coronet No. 5

Coronet No. 5, located in Plant City, Florida, is a privately owned dam with a primary purpose of storing tailings. Built in 1930, this earth dam stands at a height of 10 feet and spans 4000 feet in length, with a storage capacity of 430 acre-feet. The dam is regulated by the Florida Department of Environmental Protection and undergoes regular inspections, with a low hazard potential rating.

Situated on the English Creek/Alafia River, Coronet No. 5 plays a crucial role in water resource management in the region, with a surface area of 47 acres and a drainage area of 0.15 square miles. The dam features a controlled spillway with a width of 2 feet, capable of discharging a maximum of 20 cubic feet per second. Despite its age, the dam's condition assessment is currently "Not Rated," highlighting the need for ongoing monitoring and maintenance to ensure its long-term stability and safety.

With a very high risk rating of 1, Coronet No. 5 serves as a focal point for climate and water resource enthusiasts interested in understanding the challenges and opportunities associated with aging infrastructure. As efforts continue to mitigate risks and enhance emergency preparedness, this dam remains a critical component of the local watershed, requiring careful stewardship to safeguard its functionality and environmental impact 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.
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 Coronet No. 5

Where does the data for Coronet No. 5 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 Low 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.
