Bonner Lake Dam dam
Bonner Lake Dam
Bonner Lake Dam, located in Elbert, Georgia, is a federal-owned structure with a buttress core type and a height of 21 feet. The dam, completed in an unspecified year, stands at 225 feet in length and has a storage capacity of 61 acre-feet. Despite its uncontrolled spillway and outlet gates, the dam has a moderate hazard potential and a risk assessment rating of 3, indicating a level of risk management measures in place.
The condition of Bonner Lake Dam is currently rated as "Not Rated," with the last inspection date recorded in September 1984. While the dam's hazard potential is undetermined, its risk assessment suggests a need for ongoing monitoring and maintenance. With its location in the Charleston District and oversight by federal agencies, such as the US Army Corps of Engineers, Bonner Lake Dam remains a vital structure for water resource management in the region, providing crucial storage and flood control capabilities.
For water resource and climate enthusiasts, Bonner Lake Dam offers a fascinating case study in dam infrastructure and risk management. With its unique design features, moderate hazard potential, and historical inspection data, the dam presents an opportunity for further study and evaluation of the intersection between water resources, climate resilience, and infrastructure maintenance.
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 Bonner Lake Dam
Where does the data for Bonner Lake Dam 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 Undetermined 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.
