Vc Conley Dam dam
Vc Conley Dam
Vc Conley Dam, located in Prince William, Virginia, is a privately owned structure that plays a crucial role in water resource management and climate resilience in the region. This dam, standing at a height of 23.5 feet and with a storage capacity of 103.49 acre-feet, serves as a key component in the state-regulated water infrastructure network. Despite its undetermined hazard potential and lack of a formal condition rating, the dam remains an essential asset for flood control, water supply, and environmental protection in the area.
Managed by the Department of Conservation and Recreation in Virginia, Vc Conley Dam has not been rated for its current condition but undergoes regular inspections to ensure its structural integrity and operational readiness. The dam's primary purpose and specific design characteristics are not explicitly defined in the available data, suggesting a versatile role in water management activities. With its strategic location and significant storage capacity, the dam contributes to the sustainability of the local ecosystem and provides essential water resources for various stakeholders in the region.
As water resource and climate enthusiasts continue to monitor and assess the role of Vc Conley Dam in the broader context of environmental conservation and climate adaptation, its presence as a regulated structure with state oversight highlights the importance of proactive management and maintenance practices. The dam's capacity to store water, mitigate flood risks, and support diverse ecological functions underscores its significance in sustaining the region's water security and resilience to 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 Vc Conley Dam
Where does the data for Vc Conley 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.
