Uunet Lower Pond Dam dam
Uunet Lower Pond Dam
Uunet Lower Pond Dam, located in Loudoun, Virginia, is a privately-owned structure designed for flood risk reduction along the Broad Run tributary. This earth dam stands at a height of 13 feet, with a length of 675 feet and a storage capacity of 61.8 acre-feet. With a primary purpose of flood risk reduction, the dam plays a crucial role in mitigating potential flooding in the area.
Managed by the Department of Conservation and Recreation in Virginia, Uunet Lower Pond Dam is state-regulated and undergoes regular inspections to ensure its structural integrity and functionality. Despite being categorized as having an undetermined hazard potential and not being rated for condition assessment, the dam serves as a vital infrastructure for water resource management in the region. The dam's location and design make it a key component in the overall flood control strategy for the area.
As water resource and climate enthusiasts, understanding the significance of structures like Uunet Lower Pond Dam is crucial for sustainable water management and disaster risk reduction efforts. By recognizing the role of dams in flood control and the importance of regular inspections and maintenance, we can work towards safeguarding our communities and natural environments from the impacts of extreme weather events and climate change.
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 Uunet Lower Pond Dam
Where does the data for Uunet Lower Pond 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.
