Lake Henry Dam dam
Lake Henry Dam
Lake Henry Dam, located in Crawford, Georgia, was completed in 1955 and stands at a height of 16.2 feet, serving primarily for recreational purposes. The dam, constructed by the Natural Resources Conservation Service, holds a storage capacity of 177 acre-feet and spans 400 feet in length. Situated on Lee Creek, the dam boasts a low hazard potential and a moderate risk assessment, making it a vital component of the region's water resource management.
Despite its private ownership, Lake Henry Dam is subject to state inspection and regulation, ensuring its structural integrity and safety. With a drainage area of 1250 acres and a normal storage capacity of 107 acre-feet, the dam not only provides recreational opportunities but also plays a crucial role in managing water resources in the area. While the dam's condition is currently not rated, its low hazard potential and moderate risk assessment indicate a reliable and secure infrastructure for climate and water resource enthusiasts to appreciate and study.
The dam's uncontrolled spillway, combined with its buttress core type, reflects a traditional yet effective design that has stood the test of time. With a picturesque surface area of 16.5 acres and a location that offers a serene escape in Roberta, Georgia, Lake Henry Dam serves as both a recreational haven and a valuable asset in the region's water resource management efforts. Climate and water resource enthusiasts can admire the dam's engineering feats while appreciating its role in maintaining the delicate balance of water storage and usage in the area.

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 Lake Henry Dam
Where does the data for Lake Henry 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.
