Speedwell Farm Dam dam
Speedwell Farm Dam
Speedwell Farm Dam in Loudoun, Virginia is a privately owned structure that plays a crucial role in water resource management in the area. Standing at a height of 25.5 feet and with a storage capacity of 24.79 acre-feet, this dam helps regulate water levels and protect against flooding. The dam is state-regulated and falls under the jurisdiction of the Department of Conservation and Recreation, ensuring that it meets all necessary safety and inspection standards.
Located in the Baltimore District, Speedwell Farm Dam is an essential part of the local infrastructure, contributing to the overall water management efforts in the region. While the hazard potential of the dam is currently undetermined, its condition is assessed as not rated, indicating that there may be room for improvement or further evaluation. With a spillway type and other specific details not provided, the dam serves as a reminder of the importance of maintaining and monitoring water resources in the face of climate change and increasing water variability.
For water resource and climate enthusiasts, Speedwell Farm Dam offers a fascinating case study in the intersection of infrastructure, regulation, and environmental stewardship. As a privately owned structure with state oversight, the dam represents a collaborative effort to safeguard water resources and mitigate potential risks. Its location in Loudoun, Virginia underscores the importance of localized solutions in addressing water management challenges, while also highlighting the need for ongoing assessment and maintenance to ensure the dam's continued effectiveness 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 Speedwell Farm Dam
Where does the data for Speedwell Farm 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.
