Blenheim Road Se Dam dam
Blenheim Road Se Dam
Blenheim Road Se Dam in Powhatan, Virginia, is a state-regulated structure managed by the Department of Conservation and Recreation. This earth dam, standing at a height of 23 feet with a length of 400 feet, serves primarily for recreational purposes along the tributary of Deep Creek. With a storage capacity of 177 acre-feet, the dam has not been rated for its condition assessment and poses an undetermined hazard potential.
Located within the Norfolk District of Virginia, Blenheim Road Se Dam is yet to undergo a comprehensive risk assessment or have an Emergency Action Plan (EAP) in place. Despite its unclassified risk status, the dam remains subject to state inspection, enforcement, and permitting processes. As water resource and climate enthusiasts, the unique characteristics of this dam present an opportunity to study the environmental impact and resilience of such structures within the region.
As the dam continues to attract visitors for recreational activities, the lack of a formal risk assessment raises questions about its long-term safety and management. For those interested in water resource management and climate adaptation, Blenheim Road Se Dam offers a case study in the intersection of infrastructure, regulation, and environmental stewardship. Further research and attention to the dam's condition and emergency preparedness could provide valuable insights into sustainable dam management practices in the face of changing climate conditions.

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 Blenheim Road Se Dam
Where does the data for Blenheim Road Se 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.
