Do Gypsum dam
Do Gypsum
Located in Hamilton, Florida, the Do Gypsum dam stands as a critical structure on the Swift Creek, with a primary purpose of containing tailings. This privately-owned earth dam reaches a height of 100 feet and has a hydraulic height of 95 feet, making it a significant contributor to water resource management in the area. With a storage capacity of 52,500 acre-feet and a surface area of 500 acres, the dam plays a vital role in regulating water flow and ensuring adequate water supply for surrounding areas.
The Do Gypsum dam is state-regulated and undergoes regular inspections to maintain its structural integrity and safety. Its controlled spillway, with a width of 32 feet, helps to manage water levels during periods of excess flow, minimizing the risk of flooding and ensuring efficient water discharge. Despite its significant hazard potential, the dam has been assessed as satisfactory in condition, reflecting responsible management practices and a commitment to maintaining its functionality for the benefit of the community and the environment.
With a very high risk assessment level and a history of meeting regulatory guidelines, the Do Gypsum dam serves as a key component of water resource infrastructure in the region. Its strategic location and design contribute to effective water storage and management, supporting both agricultural activities and environmental conservation efforts. As climate change continues to impact water resources, structures like the Do Gypsum dam play a crucial role in adapting to changing conditions and ensuring sustainable water utilization for future generations.
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 Do Gypsum
Where does the data for Do Gypsum 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.
