B. Vann Dam dam
B. Vann Dam
B. Vann Dam, located in Sampson, North Carolina, is a private earth dam primarily used for recreation purposes. This dam stands at a structural height of 20.2 feet with a hydraulic height of 16.8 feet, providing a maximum storage capacity of 37.98 acre-feet. The dam overlooks the Sevenmile Swamp-Trib and covers a surface area of 4.7 acres with a drainage area of 66.6 square miles, making it a vital water resource in the region.
Despite its recreational purpose, B. Vann Dam has a high hazard potential, emphasizing the importance of regular inspections and maintenance. The last inspection conducted in December 2020 rated the dam's condition as "Not Rated," suggesting a need for further assessment. With no state regulation or permitting in place, it is crucial for private owners to take responsibility for the upkeep and safety of this water structure to prevent any potential risks or emergencies.
While B. Vann Dam does not fall under the jurisdiction of federal agencies or the US Army Corps of Engineers, its location and purpose make it a significant asset for water enthusiasts and climate advocates in the area. This dam serves not only as a recreational spot but also as a reminder of the importance of proper management and maintenance of water resources to ensure safety and sustainability for future generations.

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 B. Vann Dam
Where does the data for B. Vann 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.
