Flint Creek Structure dam
Flint Creek Structure
Flint Creek Structure, also known as Hil1, is a state-regulated dam located in Hillsborough, Florida, specifically in Temple Terrace. This structure serves multiple purposes, including flood risk reduction, recreation, and water supply. With a dam height of 10 feet and a controlled spillway width of 32 feet, the dam has a maximum storage capacity of 6635 acre-feet and a normal storage capacity of 1651 acre-feet. The dam is classified as an Earth dam with a Buttress core type, and it has a hazard potential of High, with a condition assessment rated as Fair as of the last inspection in 2016.
The Flint Creek Structure plays a crucial role in managing water resources in the area, particularly in mitigating flood risks along the Lake Thonotosassa. Its strategic location and design contribute to its effectiveness in flood risk reduction while also providing opportunities for recreational activities and ensuring a stable water supply for the surrounding communities. Despite its high hazard potential, the dam's fair condition and regular state inspections indicate a commitment to maintaining its structural integrity and minimizing risks to the public and the environment.
As a key infrastructure managed by the state of Florida, the Flint Creek Structure underscores the importance of proactive water resource management in the face of climate change challenges. With a risk assessment indicating very high risk, it is essential for regulatory agencies like FDEP to continue overseeing the dam's operations, inspections, and enforcement to ensure the safety and resilience of the structure in the long term. The dam's significant storage capacity and role in flood risk reduction highlight its critical function in safeguarding the local community against potential water-related disasters.

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 Flint Creek Structure
Where does the data for Flint Creek Structure 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 High 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.
