Blackmon Lake Dam dam
Blackmon Lake Dam
Blackmon Lake Dam in Muscogee, Georgia, is a privately owned earth dam constructed in 1955 primarily for recreation purposes. Standing at a height of 30 feet and spanning 620 feet in length, this dam has a storage capacity of 800 acre-feet and covers a surface area of 28 acres. Despite its intended recreational use, the dam poses a high hazard potential and is currently classified as being in poor condition.
Managed by the Georgia-SAFE DAMS PROGRAM, Blackmon Lake Dam undergoes regular state inspections, with the last assessment conducted in March 2017. The dam's maintenance and safety protocols are deemed to be in need of improvement, as indicated by its moderate risk assessment rating of 3. Enforcing agencies are actively involved in monitoring the dam's structural integrity and ensuring compliance with state regulations to mitigate potential risks to the surrounding environment and community.
While Blackmon Lake Dam serves as a popular recreational spot in the Biggers Lake Environs, its current condition and hazard potential highlight the importance of ongoing maintenance and risk management measures. As water resource and climate enthusiasts, staying informed about the dam's status and advocating for necessary improvements can help safeguard both the dam's recreational value and the safety of those who enjoy it.

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 Blackmon Lake Dam
Where does the data for Blackmon 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 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.
