Beauregard Dam No. 1 dam
Beauregard Dam No. 1
Beauregard Dam No. 1, located in Culpeper, Virginia, is a private earth dam primarily used for water supply purposes. This dam, standing at a height of 20 feet and a length of 350 feet, has a storage capacity of 96 acre-feet, with a normal storage level of 72 acre-feet. Situated on Flat Run, this dam is regulated by the Department of Conservation and Recreation in Virginia, ensuring that it meets state inspection, permitting, and enforcement requirements.
While the hazard potential of Beauregard Dam No. 1 is currently listed as undetermined and its condition assessment is marked as not rated, it remains an essential structure for water resource management in the area. The dam's emergency action plan status, risk assessment, and management measures are yet to be fully documented, highlighting the need for further evaluation and preparedness. With its close proximity to the Baltimore District of the US Army Corps of Engineers, the dam plays a crucial role in ensuring a stable water supply for the region.
As a key player in water supply and recreation, Beauregard Dam No. 1 serves as a vital infrastructure for the local community. With the potential for future modifications and improvements to enhance its safety and efficiency, this dam stands as a testament to the ongoing efforts to manage water resources and mitigate climate-related challenges in Virginia. Enthusiasts interested in water resource management and climate resilience will find Beauregard Dam No. 1 to be a significant point of interest in the region.

About Beauregard Dam No. 1
Where does the data for Beauregard Dam No. 1 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 Undetermined 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 below 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.
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.
