S-60 dam
S-60
S-60, located in Osceola, Florida, is a state-regulated Earth dam completed in 1966 for the primary purpose of Flood Risk Reduction on Alligator Lake. Standing at a height of 23 feet, with a structural height of 16 feet and a length of 97 feet, S-60 has a storage capacity of 73,000 acre-feet and a normal storage capacity of 43,000 acre-feet. With a significant hazard potential, the dam's condition was last assessed as satisfactory in August 2014.
Despite being owned and regulated by the state of Florida, S-60 falls under the jurisdiction of the Jacksonville District of the US Army Corps of Engineers. The dam is situated in St. Cloud and serves as a crucial structure for managing flood risks in the region. With a maximum discharge capacity of 450 cubic feet per second, S-60 plays a vital role in protecting the surrounding area from potential inundation. While the last inspection dates back to 1905, the dam's condition remains satisfactory as per the latest assessment in 2014.
Overall, S-60 is a key component of the flood risk reduction infrastructure in Osceola, Florida. As a state-regulated Earth dam, it provides essential protection for Alligator Lake and the surrounding areas from potential flooding events. With a significant hazard potential, the dam's satisfactory condition and adequate storage capacity highlight its importance in safeguarding the local community from water-related risks.
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 S-60
Where does the data for S-60 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.
