Har4 dam
Har4
Har4 is a private dam located in Hardee, Florida, specifically in the city of Wauchula. This dam, with a height of 7 feet and a length of 13,193 feet, serves the primary purpose of tailings management. It is classified as an earth dam and has a storage capacity of 6,764.4 acre-feet, with a normal storage level of 5,186.04 acre-feet. The dam is situated on an unnamed pond and falls under the regulatory jurisdiction of the Florida Department of Environmental Protection (FDEP), with state permitting, inspection, and enforcement in place.
Despite its importance in managing tailings, the hazard potential of Har4 is currently labeled as 'Undetermined', with a condition assessment of 'Not Rated'. The dam has not been modified in recent years, and specific details such as the year of completion and the presence of spillways or outlet gates are not available. Emergency preparedness measures, such as the existence of an Emergency Action Plan (EAP) or updated contact information, are also not specified. Overall, while Har4 serves a critical function in the area, there are gaps in information regarding its safety assessment and risk management strategies.
Located in the Jacksonville District of the US Army Corps of Engineers, Har4 offers a significant storage capacity and is essential for tailings operations in the region. As a private structure, it is subject to state regulations and oversight, ensuring that it meets the necessary standards for operation. Water resource and climate enthusiasts interested in the intersection of infrastructure, environmental protection, and emergency preparedness may find Har4 to be a compelling case study for understanding the complexities of dam management and risk mitigation in the face of potential hazards.

About Har4
Where does the data for Har4 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.
