Hil17 Dam
Hil17
Hil17, located in Plant City, Florida, is a private dam regulated by the state with a primary purpose of storing tailings. Standing at a height of 8.29 feet and with a length of 9419 feet, Hil17 has a storage capacity of 7728 acre-feet, with a normal storage level of 4114.56 acre-feet. The dam is situated on an unnamed pond and is owned by a private entity, with state permitting, inspection, and enforcement in place.
Although the dam's hazard potential is currently labeled as undetermined and its condition assessment is not rated, Hil17 serves as a critical water resource infrastructure in the region. With its significant storage capacity and strategic location, the dam plays a crucial role in managing water resources in Hillsborough County, Florida. Despite the lack of recent inspection data and condition assessment, Hil17 remains an essential component of the local water management infrastructure.
As water resource and climate enthusiasts, it is important to monitor and assess the condition of dams like Hil17 to ensure their continued function and safety. With the potential risks associated with dams, especially in the face of changing climate conditions, staying informed about the status of critical water infrastructure is crucial for sustainable water management and environmental resilience. As efforts continue to maintain and improve water infrastructure across the country, understanding the data and characteristics of dams like Hil17 is essential for informed decision-making and effective resource management.

About Hil17
Where does the data for Hil17 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 below 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.
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.
