N S Haltam Lake Dam dam
N S Haltam Lake Dam
N S Haltam Lake Dam, located in Clarke, Alabama, is a private earth dam built in 1968 primarily for recreation purposes. This dam stands at a hydraulic height of 21 feet and a structural height of 22 feet, with a length of 320 feet. It has a storage capacity of 50 acre-feet and a maximum discharge of 66 cubic feet per second. The dam is situated along the TR-LONG BRANCH river or stream, serving as a popular spot for outdoor activities in the community along CO RD 48.
Despite its recreational significance, N S Haltam Lake Dam poses a significant hazard potential and has not been rated for its current condition. It is not state-regulated or inspected, and there are no emergency action plans in place as of the last data update in 2015. The dam's risk assessment, management measures, and inundation maps remain undocumented, raising concerns about the safety and resilience of the structure in the face of potential climate-related challenges.
For water resource and climate enthusiasts, N S Haltam Lake Dam presents an intriguing case study of a privately owned dam with limited oversight and risk mitigation measures. As climate change continues to impact water infrastructure across the country, there is a growing need to assess and enhance the resilience of structures like N S Haltam Lake Dam to ensure the safety of surrounding communities and the sustainability of water resources in the face of evolving environmental conditions.

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 N S Haltam Lake Dam
Where does the data for N S Haltam 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 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.
