Epperson Dam dam
Epperson Dam
Epperson Dam, located in Patrick, Virginia, is a privately owned structure that falls under the regulatory jurisdiction of the Department of Conservation and Recreation. This earth dam stands at a height of 31 feet and stretches for 610 feet, providing a storage capacity of 149 acre-feet. With a normal storage capacity of 118 acre-feet and a surface area of 11 acres, Epperson Dam plays a crucial role in water resource management in the region.
Although the condition assessment of Epperson Dam is currently marked as "Not Rated," its hazard potential is listed as "Undetermined." The dam has not been assigned a risk assessment or management measures, and there is no Emergency Action Plan (EAP) in place. Despite these uncertainties, the dam is subject to state regulation, inspection, and enforcement, ensuring that necessary precautions are taken to prevent any potential risks associated with its operations.
As a significant infrastructure within the Huntington District, Epperson Dam serves as a key player in water resource management in the area. Its strategic location and storage capacity make it an essential component in addressing water needs and maintaining the ecological balance of the region. Moving forward, it will be important to evaluate and address any potential risks associated with the dam to ensure its continued safe and effective operation for the benefit of both the local community and the environment.

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 Epperson Dam
Where does the data for Epperson 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.
