Haynes Creek- Brushy Fork Creek Ws Str. # 21 dam
Haynes Creek- Brushy Fork Creek Ws Str. # 21
Haynes Creek- Brushy Fork Creek WS Str. # 21, also known as Brushy Haynes Creek WS Str # 21, is a state-owned water structure located in Gwinnett, Georgia. Built in 1965 by the Natural Resources Conservation Service, this earth dam stands at 32.2 feet high and spans 1040 feet in length. With a primary purpose of flood risk reduction, it serves to protect the surrounding areas from potential flooding along the Brushy Fork Creek.
Covering a drainage area of 1030 acres, this dam has a storage capacity of 416 acre-feet, with a normal storage level of 324 acre-feet. Despite its fair condition assessment as of February 2020, the structure has a high hazard potential due to its proximity to populated areas. Regular inspections are conducted every two years to ensure its safety and functionality. While the risk assessment indicates a moderate level of risk, the dam's emergency action plan status and inundation maps remain unspecified, signaling a need for further preparedness measures in case of emergencies.
As an integral part of the flood risk management system in the region, Haynes Creek- Brushy Fork Creek WS Str. # 21 plays a crucial role in safeguarding the community from potential water-related disasters. With its strategic location and design features, this dam serves as a vital resource for water resource and climate enthusiasts interested in understanding the intersection of infrastructure and environmental protection in Georgia.
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 Haynes Creek- Brushy Fork Creek Ws Str. # 21
Where does the data for Haynes Creek- Brushy Fork Creek Ws Str. # 21 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 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.
