Dupont Highland Settling Area dam
Dupont Highland Settling Area
Dupont Highland Settling Area is a privately owned earth dam located in Clay Hill Church, Florida, along the Boggy Branch river. Completed in 1976, this dam stands at a height of 20 feet and spans a length of 3400 feet, providing a storage capacity of 752 acre-feet. With a surface area of 196 acres and a normal storage level of 432 acre-feet, this dam serves a significant purpose in water resource management in the region.
Despite being privately owned, Dupont Highland Settling Area falls under state jurisdiction, with regulations and inspections in place to ensure its safe operation. Classified as a significant hazard potential dam with a satisfactory condition assessment, this structure is designed to handle controlled spillways and has a very high risk assessment rating. The dam's emergency action plan status and risk management measures remain unspecified, indicating a potential area for improvement in the future.
For water resource and climate enthusiasts, Dupont Highland Settling Area offers a fascinating example of how privately owned dams play a crucial role in managing water resources in Florida. With its significant storage capacity and strategic location, this earth dam serves as a key infrastructure for flood control and water supply management in the region. As efforts continue to ensure the safety and efficiency of this structure, it stands as a testament to the intricate balance between human intervention and environmental stewardship in water resource management.
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 Dupont Highland Settling Area
Where does the data for Dupont Highland Settling Area 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.
