Lake Tomahawk Dam dam
Lake Tomahawk Dam
Lake Tomahawk Dam, located in Black Mountain, North Carolina, is a key recreational water resource managed by the local government. Built in 1935, this earth dam stands at a height of 22 feet and has a hydraulic height of 17 feet, providing a storage capacity of 85 acre-feet. The dam's primary purpose is recreation, offering a surface area of 9.6 acres for outdoor activities and a maximum discharge capacity of 750 cubic feet per second. Despite its high hazard potential, the dam's condition was assessed as satisfactory during the last inspection in March 2019.
This dam on Tomahawk Branch is regulated by the North Carolina Dam Safety Program, ensuring that state permitting, inspection, and enforcement protocols are in place for its operation. The dam's emergency action plan (EAP) status and risk management measures are currently unspecified, indicating a potential area for improvement in emergency preparedness. The dam's association with the Wilmington District of the US Army Corps of Engineers highlights its importance in water resource management within the region. For water resource and climate enthusiasts, Lake Tomahawk Dam serves as a focal point for understanding the intersection of recreational amenities, regulatory oversight, and safety considerations in dam infrastructure.
Dam data reference
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 Tomahawk Dam
Where does the data for Lake Tomahawk 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.
