Har3 dam
Har3
Har3, located in Hardee, Florida, is a private dam regulated by the Florida Department of Environmental Protection. Standing at a height of 7 feet and stretching over 15,000 feet in length, Har3 serves as a tailings dam with a storage capacity of over 10,000 acre-feet. The dam is situated on an unnamed pond and is designated for the purpose of tailings containment, making it a crucial structure for water resource management in the area.
Despite its importance, Har3's hazard potential remains undetermined, and its condition assessment is listed as "Not Rated." The dam's emergency action plan status, risk assessment, and management measures are also lacking detailed information. With its location in a region susceptible to climate variability and extreme weather events, the need for comprehensive monitoring and maintenance of Har3 is crucial to ensure the safety and sustainability of the surrounding environment and water resources.
As a part of the Jacksonville District under the ownership of a private entity, Har3 stands as a significant structure in the local water infrastructure. With its storage capacity and purpose for tailings containment, the dam plays a vital role in water resource management in the region. As water resource and climate enthusiasts, it is imperative to stay informed about the condition and regulatory status of dams like Har3 to ensure the protection of water resources and the surrounding ecosystem.

About Har3
Where does the data for Har3 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.

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.
