Main Stack dam
Main Stack
Main Stack is a private earth dam located in Hillsborough, Florida, specifically in the city of Gibsonton. Built in 1989 by ARDAMAN & ASSOCIATES, this dam stands at a towering height of 103 feet, with a hydraulic height of 98 feet and a structural height of 103 feet. It serves primarily for tailings storage, with a storage capacity of 16,000 acre-feet and a surface area of 251 acres.
The dam is regulated by the Florida Department of Environmental Protection (FDEP) and undergoes regular state inspections, permitting, and enforcement. With a significant hazard potential and a high risk assessment rating of 2, Main Stack poses potential risks that need to be managed effectively. Despite not having a spillway or outlet gates, the dam has not been rated for its condition as of yet, highlighting the importance of continuous monitoring and assessment to ensure its structural integrity and safety.
With the dam situated along Archie Creek and falling under the jurisdiction of the Jacksonville District of the US Army Corps of Engineers, Main Stack is a key infrastructure for water resource management in the region. As climate change continues to impact water resources, understanding and maintaining the integrity of such structures is crucial for mitigating potential risks and ensuring the sustainable management of our water supply.
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 Main Stack
Where does the data for Main Stack 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.
