Lake Hargis Dam dam
Lake Hargis Dam
Lake Hargis Dam, located in the picturesque Mt. Signal Community in Shelby, Alabama, was completed in 1955 and serves as a vital water resource for the region. This private dam, with a hydraulic height of 22 feet and a structural height of 23 feet, provides recreation opportunities and maintains a storage capacity of 106 acre-feet. The dam, situated on the TR-Little Creek river, has a significant hazard potential and is currently not rated for its condition.
Despite not being regulated by the state, Lake Hargis Dam plays a crucial role in managing water flow and providing a safe environment for recreational activities. With a maximum discharge capacity of 100 cubic feet per second, the dam ensures the safety and well-being of the surrounding community. The dam's unique design and purpose make it a noteworthy landmark in the area, attracting water resource and climate enthusiasts interested in exploring its impact on the local ecosystem.
While further assessments and inspections are needed to evaluate its condition and potential risks, Lake Hargis Dam remains a key feature in the region's water management infrastructure. As water resource enthusiasts continue to study and appreciate the dam's role in maintaining a balance between recreation and conservation, its significance in the larger context of climate resilience and resource management becomes increasingly apparent.

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 Hargis Dam
Where does the data for Lake Hargis 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 Significant 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.
