Etowah River 4 dam
Etowah River 4
Etowah River 4 is a vital flood risk reduction structure located in Gober, Forsyth County, Georgia. Constructed in 1959 by the USDA NRCS, this earth dam stands at a height of 32 feet and spans 440 feet in length, providing critical protection to the surrounding area. With a storage capacity of 643 acre-feet and a drainage area of 2.38 square miles, the dam plays a key role in managing the flow of Bannister Creek and minimizing the risk of flooding for the community.
Despite its significant hazard potential, the condition assessment of Etowah River 4 is currently not available, highlighting the need for regular inspections and maintenance to ensure its continued effectiveness. The dam's spillway type is uncontrolled, with a width of 150 feet, and a maximum discharge capacity of 1040 cubic feet per second. While the risk assessment categorizes the structure as having a moderate risk level, there is a lack of detailed risk management measures and emergency action plans in place, emphasizing the importance of ongoing monitoring and preparedness efforts.
Water resource and climate enthusiasts will appreciate the critical role that Etowah River 4 plays in flood risk reduction within the region. As a local government-owned structure funded and designed by the USDA NRCS, this dam serves as a key asset in safeguarding the community against potential flooding events. With its strategic location on Bannister Creek and its substantial storage capacity, the dam remains a vital piece of infrastructure that requires regular inspections and maintenance to ensure its continued functionality and resilience in the face of changing weather patterns and hydrological conditions.
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 Etowah River 4
Where does the data for Etowah River 4 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 Significant 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.
