James "Sloppy" Floyd Upper Dam dam
James "Sloppy" Floyd Upper Dam
James "Sloppy" Floyd Upper Dam, located in Summerville, Georgia, was completed in 1970 and is owned by the state. The dam, primarily designed for recreational purposes, is an earth dam with a height of 30 feet and a length of 300 feet, creating a reservoir with a maximum storage capacity of 253 acre-feet. The dam is situated on the Marble Spring Branch and is managed by the Natural Resources Conservation Service.
Despite being classified as having a low hazard potential, the dam has not been rated for its condition assessment, and its last inspection took place in February 2018 with a frequency of every 5 years. The risk assessment for the dam is moderate, indicating some potential vulnerabilities that may need to be addressed. While the dam has uncontrolled spillways and outlet gates, it is not regulated by the state and does not have a permit for operation, although it is subject to state inspection. Overall, James "Sloppy" Floyd Upper Dam provides a valuable recreational resource in Chattooga County, Georgia, while also raising awareness about the importance of proper dam maintenance and risk management in water resource and climate conservation efforts.

About James "Sloppy" Floyd Upper Dam
Where does the data for James "Sloppy" Floyd Upper Dam 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 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.
