Keysville (N) dam
Keysville (N)
Keysville (N) is a privately owned dam located in Polk, Florida, specifically in the city of Mulberry. This earth-type dam, with a height of 100 feet and a hydraulic height of 95 feet, serves the primary purpose of containing tailings. With a storage capacity of 896 acre-feet, the dam sits on the unnamed pond and has a controlled spillway with a width of 64 feet. The dam has a significant hazard potential and a very high risk assessment rating, making it crucial for proper monitoring and maintenance.
Despite being privately owned, Keysville (N) is regulated by the state of Florida and is subject to state permitting, inspection, and enforcement. The dam has not been rated for its condition assessment, and there is limited information available regarding emergency action plans and risk management measures. With a drainage area of 0.07 square miles and a maximum discharge of 110 cubic feet per second, the dam plays a critical role in managing water resources in the region.
As water resource and climate enthusiasts, it is essential to keep a close eye on structures like Keysville (N) to ensure their safety and effectiveness in water management. With its significant hazard potential and high risk assessment, it is crucial for the dam to be regularly inspected and maintained to prevent any potential disasters. The dam's location in Polk, Florida, highlights the importance of sustainable water resource management practices in the face of changing climate conditions.

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 Keysville (N)
Where does the data for Keysville (N) 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.
