Grove River Ws Str # 15 dam
Grove River Ws Str # 15
Located in the Gillsville Community of Banks, Georgia, Grove River WS Str # 15 is a state-regulated earth dam designed by the Natural Resources Conservation Service in 1969. With a primary purpose of flood risk reduction, this dam stands at a height of 39 feet and has a hydraulic height of 48 feet, providing a maximum storage capacity of 340 acre-feet. The dam spans a length of 490 feet and covers a surface area of 5 acres, serving a drainage area of 0.86 square miles.
Despite its critical function in flood control, Grove River WS Str # 15 has been flagged with a high hazard potential due to its poor condition assessment as of October 2012. The dam has not undergone any modifications in recent years and lacks detailed risk management measures or emergency preparedness protocols. While the structure is inspected biennially, its inadequate maintenance and outdated safety features highlight the urgency for improved monitoring and maintenance practices to mitigate the risks associated with its deteriorating condition.
Given its significance in safeguarding the local community from potential flooding events, stakeholders and authorities must prioritize the rehabilitation and modernization of Grove River WS Str # 15 to ensure its continued effectiveness and safety. By addressing the identified deficiencies and implementing comprehensive risk management strategies, this dam can fulfill its vital role in flood risk reduction while minimizing the potential threats posed by its current state.水Resources and climate enthusiasts are encouraged to advocate for proactive measures to safeguard this essential water resource and enhance its resilience to future challenges.

About Grove River Ws Str # 15
Where does the data for Grove River Ws Str # 15 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.
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.
