George Mann dam
George Mann
Located in Lee County, Alabama, the George Mann dam stands as a vital water resource managed by the USDA NRCS. Built in 1971, this Earth-type dam serves the primary purpose of creating a fish and wildlife pond while also providing a recreational area for visitors. With a height of 24 feet and a length of 360 feet, the dam boasts a storage capacity of 158 acre-feet and a drainage area of 0.16 square miles.
The dam's spillway, characterized as uncontrolled, features a width of 42 feet to manage a maximum discharge of 560 cubic feet per second. Despite being rated with a low hazard potential, the risk assessment for George Mann indicates a moderate level of risk. While the condition assessment remains unrated, the dam's maintenance and operation are not regulated by any state agency, reflecting a need for ongoing monitoring and management to ensure its long-term stability and safety.
For water resource and climate enthusiasts, George Mann presents an intriguing case study in sustainable dam management. As a critical structure in the Mobile District of Alabama, this dam serves as a key habitat for fish and wildlife while offering recreational opportunities for the local community. With its unique design and historical significance, George Mann stands as a testament to the importance of responsible water resource management in preserving the natural environment and supporting the diverse ecosystem of Robinson Creek.
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 George Mann
Where does the data for George Mann 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 Low 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.
