Haynes-Brushy Fork Creek Ws Str. # 3 dam
Haynes-Brushy Fork Creek Ws Str. # 3
Haynes-Brushy Fork Creek WS Str. # 3, also known as H3, is a state-owned earth dam located in Gwinnett County, Georgia. Built in 1965 by the Natural Resources Conservation Service, this dam serves the primary purpose of flood risk reduction along Big Haynes Creek. Standing at 34 feet high with a hydraulic height of 27 feet, this structure has a storage capacity of 800 acre-feet and covers a surface area of 15 acres.
Despite its age, Haynes-Brushy Fork Creek WS Str. # 3 is in satisfactory condition according to its last inspection in January 2016. However, it has a high hazard potential, indicating the potential for significant consequences in the event of a failure. The dam is regulated by the Georgia Safe Dams Program and undergoes regular state inspections and enforcement to ensure its safety and functionality. The risk assessment for this dam is moderate, emphasizing the importance of continued monitoring and maintenance to mitigate potential risks.
Water resource and climate enthusiasts will find Haynes-Brushy Fork Creek WS Str. # 3 an intriguing structure due to its role in flood risk reduction and its location in a critical watershed area. The dam's design by the SCS and its association with the Natural Resources Conservation Service highlight the importance of sustainable water management practices in safeguarding communities and ecosystems. With its history dating back to the mid-20th century, this dam serves as a testament to the ongoing efforts to balance water resource development with environmental conservation 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-Brushy Fork Creek Ws Str. # 3
Where does the data for Haynes-Brushy Fork Creek Ws Str. # 3 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.
