Green Bay Gypstack Cell 1 dam
Green Bay Gypstack Cell 1
Green Bay Gypstack Cell 1, located in Polk, Florida, is a privately owned structure used for tailings storage. Completed in 1965, this earth dam has a height of 80 feet and a storage capacity of 2072 acre-feet. With a surface area of 250 acres and a drainage area of 0.39 square miles, this dam on Six Mile Creek has a significant hazard potential and is regulated by the Florida Department of Environmental Protection.
The dam's primary purpose is for tailings storage, and it has a hydraulic height of 75 feet and a structural height of 85 feet. The dam is primarily constructed of soil and spans a length of 11,000 feet. While the condition assessment is not rated, the last inspection took place in September 2005. With a maximum discharge capacity of 215 cubic feet per second and a spillway width of 32 feet, this dam plays a crucial role in managing water resources in the area.
Green Bay Gypstack Cell 1 is a key structure in the region, providing vital tailings storage and flood control capabilities. With its significant hazard potential, it is essential that the dam continues to be regulated, inspected, and maintained to ensure the safety of the surrounding communities and the environment. As water resource and climate enthusiasts, understanding the details of this dam's design, purpose, and operational characteristics is crucial in managing water resources effectively in the face of changing climate conditions.

About Green Bay Gypstack Cell 1
Where does the data for Green Bay Gypstack Cell 1 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 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.
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.
