Hil11 dam
Hil11
Hil11, a private-owned dam located in Plant City, Florida, serves primarily as a tailings dam with an earth core structure standing at a height of 12.67 feet. The dam's purpose is to control the flow of water in an unnamed pond, providing storage of up to 4,395.21 acre-feet. Despite its importance in managing water resources, the condition assessment of Hil11 is currently listed as "Not Rated," leaving its hazard potential undetermined.
Operated under state jurisdiction by the Florida Department of Environmental Protection, Hil11 is subject to regular inspections, permitting, and enforcement measures to ensure its safety and compliance with regulations. The dam, completed at an unspecified date, spans 3,958 feet in length and covers a surface area of 23 acres. While the risk assessment and emergency preparedness details for Hil11 remain unclear, its location in Hillsborough County signifies its significance in the local water resource management infrastructure.
With its proximity to the Jacksonville District of the US Army Corps of Engineers and oversight by federal and state agencies, Hil11 plays a crucial role in water resource management in the area. The dam's association with tailings and its substantial storage capacity underscore its importance in maintaining water quality and quantity in the region. As water resource and climate enthusiasts, understanding the operations and condition of dams like Hil11 is essential for ensuring sustainable water management practices for the future.

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 Hil11
Where does the data for Hil11 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 Undetermined 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.
