Kingsford H1 dam
Kingsford H1
Kingsford H1 is a privately owned earth dam located in Polk, Florida, along the Alafia River. Completed in 1970, this dam serves the primary purpose of tailings storage, with a structural height of 38 feet and a hydraulic height of 30 feet. The dam has a storage capacity of 13,700 acre-feet and covers a surface area of 428 acres, with a controlled spillway width of 64 feet.
With a significant hazard potential and a very high risk assessment rating, Kingsford H1 requires careful monitoring and maintenance. While the dam's condition assessment is currently listed as "Not Rated", it is regulated by the Florida Department of Environmental Protection, with state permitting, inspection, and enforcement in place. Despite its age, the dam has not undergone any modifications in recent years and lacks emergency action plans in case of a potential failure.
Water resource and climate enthusiasts interested in Kingsford H1 can appreciate the dam's vital role in tailings storage along the Alafia River. Its location in a high-risk area underscores the importance of regular inspections and risk management measures to ensure the safety and integrity of the structure. As a part of the broader water infrastructure in Florida, Kingsford H1 serves as a reminder of the ongoing challenges and responsibilities associated with managing and regulating dams in the face of changing environmental conditions.
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 Kingsford H1
Where does the data for Kingsford H1 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.
