South Fork River Ws Str # 31 dam
South Fork River Ws Str # 31
South Fork River WS Str # 31, also known as South Fork Broad River W/S #31, is a state-owned dam located in Diamond Hill, Georgia. Built in 1962 by the Natural Resources Conservation Service, this Earth-type dam stands at a height of 42 feet and spans a length of 808 feet. Its primary purpose is flood risk reduction, serving to protect the surrounding area from potential inundation during heavy rain events.
With a storage capacity of 1178 acre-feet and a drainage area of 3089 acres, South Fork River WS Str # 31 plays a crucial role in managing water flow along Biger Creek. However, recent assessments have deemed its condition as poor, with a high hazard potential. Despite being state-regulated and inspected, the dam's maintenance and risk management measures may need to be reassessed to ensure the safety and functionality of this vital water resource infrastructure.
As a significant structure in the Savannah District, South Fork River WS Str # 31 requires ongoing attention and monitoring to address its moderate risk level. With an outdated last inspection date in 2017, stakeholders may need to prioritize updates to emergency action plans and hazard assessments to mitigate potential risks associated with this aging dam. The collaboration between state and local government agencies will be essential in safeguarding the community and environment from the impacts of a dam failure.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

Where does the data for South Fork River Ws Str # 31 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 High 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.

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.
