Woodall Dam dam
Woodall Dam
Woodall Dam, located in Loudoun, Virginia, is a privately owned structure regulated by the Department of Conservation and Recreation. This earth dam on TR-Goose Creek stands at a height of 27 feet and spans 660 feet in length, with a storage capacity of 164.2 acre-feet. Its primary purpose is for recreation, providing a serene and picturesque spot for water resource and climate enthusiasts to enjoy.
Although the dam's hazard potential is currently undetermined and its condition is not rated, it is subject to regular inspections with a frequency of one per year. The emergency action plan status, risk assessment, and management measures are all marked as unknown, suggesting a need for further evaluation and preparation. Despite these uncertainties, Woodall Dam continues to offer a valuable recreational resource in the area, attracting visitors with its tranquil surroundings and potential for outdoor activities.
As climate change increasingly impacts water resources, the maintenance and assessment of structures like Woodall Dam become crucial for ensuring safety and sustainability. With its connection to TR-Goose Creek and the Baltimore District, this dam serves as a vital part of the local ecosystem and provides a valuable opportunity for residents and visitors to appreciate the intersection of water management and recreational enjoyment in the face of evolving environmental challenges.
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 Woodall Dam
Where does the data for Woodall 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.
