Proximity Dam dam
Proximity Dam
Proximity Dam in Loudoun, Virginia, is a privately owned structure regulated by the Department of Conservation and Recreation. Standing at a height of 29.5 feet, this dam has a maximum storage capacity of 24.9 acre-feet and a normal storage capacity of 17 acre-feet. With a surface area of 1.7 acres, the dam's hazard potential is currently listed as 'Undetermined' and its condition is marked as 'Not Rated'.
Although specific details regarding the dam's construction year and purposes are not available, its proximity to the Baltimore District and the involvement of the state regulatory agency indicate a significant role in water resource management. The dam's location along the river or stream remains unspecified, but its presence highlights the importance of maintaining water infrastructure in the region. With its state-regulated status and inspection, enforcement, and permitting in place, Proximity Dam serves as a key component in ensuring water resource sustainability in Virginia.
As a structure with a critical height and storage capacity, Proximity Dam underscores the need for ongoing risk assessment and management measures to address any potential hazards. While its emergency action plan and inundation maps status are currently unclear, the dam's condition and hazard potential should prompt further evaluation and preparation to mitigate risks. Enthusiasts of water resources and climate resilience should keep an eye on developments surrounding Proximity Dam to ensure its continued safe and efficient operation within the local ecosystem.

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 Proximity Dam
Where does the data for Proximity 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.
