Hilsman Lake Dam dam
Hilsman Lake Dam
Hilsman Lake Dam, located in Morgan County, Georgia, was completed in 1975 and serves multiple purposes including fire protection, stock, and small fish pond management. The dam is privately owned and managed, with the design work being carried out by the Natural Resources Conservation Service. The dam is classified as an earth dam with a height of 23 feet and a length of 450 feet, providing a storage capacity of 66 acre-feet.
Despite being unregulated by the state, Hilsman Lake Dam poses a low hazard potential and has a moderate risk assessment rating. The dam features an uncontrolled spillway and outlet gates, with no associated locks. While the condition assessment is currently rated as "Not Rated," the dam has not undergone recent inspections or assessments. The surrounding area is primarily used for recreational purposes, with the potential for minor impacts in the event of a dam failure.
Overall, Hilsman Lake Dam plays a crucial role in water resource management in the region, offering essential services such as fire protection and fish pond management. While the dam is deemed to have a low hazard potential, continued monitoring and maintenance are necessary to ensure the safety and integrity of the structure. As a key component of the local water infrastructure, Hilsman Lake Dam highlights the importance of proactive risk management and emergency preparedness in safeguarding water resources and surrounding communities.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Hilsman Lake Dam
Where does the data for Hilsman 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 Low 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.
