Hil410 dam
Hil410
Hil410 is a privately owned dam located in Hillsborough, Florida, specifically in the city of Plant City. This earth dam, standing at a height of 7 feet and with a length of 17,119 feet, serves the primary purpose of tailings management. It has a storage capacity of 19,449.6 acre-feet, with a normal storage level of 14,911.36 acre-feet and a surface area of 648 acres. The dam is regulated by the Florida Department of Environmental Protection (FDEP), with permitting, inspection, and enforcement all handled by the state agency.
Despite being classified as having an undetermined hazard potential and not being rated for its condition assessment, Hil410 remains an essential piece of infrastructure for managing tailings in the region. The dam has not undergone any modifications since its completion, and information on emergency preparedness, such as the existence of an emergency action plan (EAP) or inundation maps, is currently unavailable. The risk assessment, risk management measures, and other related details are also not documented for this dam. With its proximity to the UNNAMED POND river or stream, Hil410 plays a crucial role in water resource management in the area.
For water resource and climate enthusiasts, Hil410 presents an intriguing case study of a privately owned dam in Florida that plays a significant role in tailings management. Despite lacking certain key safety assessments and emergency preparedness plans, the dam continues to function within state regulatory guidelines. As discussions around dam safety and climate resilience continue to grow, monitoring and assessing structures like Hil410 will be crucial in ensuring the sustainable management of water resources in the region.

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.
Plan around the weather

About Hil410
Where does the data for Hil410 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.
