Har8 dam
Har8
Har8 is a private dam located in Manatee, Florida, with a primary purpose of storing tailings. The dam is an earth type structure with a height of 7 feet and a length of 15290 feet, providing a storage capacity of 10111.8 acre-feet. Situated in an unnamed pond, Har8 is regulated by the state of Florida and is subject to state permitting, inspection, and enforcement.
Although the hazard potential of Har8 is currently undetermined and its condition is not rated, the dam remains a key feature in the region's water resource management. With a normal storage capacity of 7752.38 acre-feet and a surface area of 337 acres, Har8 plays a crucial role in regulating water levels and ensuring water availability for various purposes. The dam's location in a sensitive ecosystem highlights the importance of regular monitoring and maintenance to prevent any potential risks to both the environment and surrounding communities.
Managed by private owners, Har8 stands as a vital infrastructure in the region's water resource system. As climate change continues to impact water availability and quality, the proper management and upkeep of dams like Har8 become increasingly critical. By staying informed and engaged in monitoring and addressing any potential risks associated with dams, water resource and climate enthusiasts can contribute to the sustainable management of these essential structures for the benefit of the environment and society.
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 Har8
Where does the data for Har8 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 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.
