Woodhall Dam dam
Woodhall Dam
Woodhall Dam, located in Union, North Carolina, is a privately owned earth dam built in 2000 for the primary purpose of recreation. Standing at a hydraulic height of 12 feet and a structural height of 13.1 feet, this dam boasts a length of 320 feet and a storage capacity of 27 acre-feet. With a drainage area of 233 square miles and a maximum discharge of 424 cubic feet per second, Woodhall Dam plays a crucial role in managing water resources in the region.
Despite its fair condition assessment and high hazard potential, Woodhall Dam is regulated by the North Carolina Department of Environmental Quality and regularly inspected to ensure its safety and compliance with state regulations. The dam, situated on a tributary to Cowhorn Branch, serves as a vital recreational area with a surface area of 5.2 acres for outdoor enthusiasts. While the dam has not been modified in recent years, it remains a significant structure for both water resource management and climate-related activities in the area.
With a focus on maintaining public safety and promoting recreational opportunities, Woodhall Dam continues to be a key asset in Union, North Carolina. As efforts are made to monitor and manage the dam's risk factors, its role in water resource management and climate resilience remains essential. As a privately owned structure with state regulation, Woodhall Dam stands as a testament to the importance of balancing environmental conservation with recreational enjoyment in the region.
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 Woodhall Dam
Where does the data for Woodhall 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.
