Swan Dam dam
Swan Dam
Swan Dam, located in Culpeper, Virginia, is a privately owned earth dam primarily used for water supply purposes. Standing at a height of 19.81 feet, the dam boasts a storage capacity of 84.64 acre-feet with a normal storage level of 70.53 acre-feet. Situated on the TR-Jonas Run river, the dam serves as a vital resource for the local community, offering both recreational opportunities and essential water supply services.
Managed by the Department of Conservation and Recreation in Virginia, Swan Dam is subject to state regulation, permitting, inspection, and enforcement to ensure its safety and functionality. While its hazard potential is currently undetermined and its condition remains unrated, the dam's emergency action plan status, risk assessment, and risk management measures are yet to be fully documented. With its picturesque location and significant water storage capacity, Swan Dam stands as a key infrastructure asset in the region, playing a crucial role in water resource management and climate resilience efforts.
Despite the lack of detailed information on its construction year and structural assessment, Swan Dam's strategic position within the Baltimore District underscores its importance in the local water supply network. As water resource and climate enthusiasts continue to monitor developments related to the dam, its role in supporting the community's water needs and contributing to environmental sustainability remains a focal point for ongoing discussions and potential future enhancements.
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 Swan Dam
Where does the data for Swan 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 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 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.
