Sallacoa Creek Watershed Structure No. 99 dam
Sallacoa Creek Watershed Structure No. 99
Located in the picturesque Sallacoa Creek Watershed in Fairmount, Georgia, Structure No. 99 stands as a testament to effective flood risk reduction efforts. Built in 1968 by the Natural Resources Conservation Service, this earth dam boasts a height of 59.5 feet and a hydraulic height of 51.3 feet, providing crucial protection to the surrounding area from potential flooding events. With a drainage area of 1018 acres and a storage capacity of 450 acre-feet, this structure plays a vital role in managing water flow and safeguarding the local community.
Despite its age, Structure No. 99 remains in good condition, with a low hazard potential and a moderate risk assessment rating. With uncontrolled spillways and outlet gates, this dam is designed to efficiently release excess water and prevent overflow, ensuring the safety of nearby residents and infrastructure. Regular inspections, the last of which was conducted in February 2018, help to maintain the structure's integrity and readiness for any potential emergency situations.
As part of the larger water management system in the area, Sallacoa Creek Watershed Structure No. 99 exemplifies the importance of strategic infrastructure in mitigating flood risks and protecting communities. With its solid design, ample storage capacity, and effective risk management measures, this structure serves as a crucial component in the preservation of the local environment and the safety of those who call Gordon County home.
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 Sallacoa Creek Watershed Structure No. 99
Where does the data for Sallacoa Creek Watershed Structure No. 99 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.
