T. Nelson Elliott Dam dam
T. Nelson Elliott Dam
Located in Prince William, Virginia, the T. Nelson Elliott Dam, also known as Broad Run Dam, stands as a crucial water supply structure managed by the local government. With a impressive height of 76 feet and a length of 1250 feet, this gravity dam on the Broad Run river serves a primary purpose of water supply, holding a storage capacity of 33,000 acre-feet and covering a surface area of 790 acres. Despite its high hazard potential, the dam has been deemed to be in satisfactory condition as of the last inspection in September 2020.
Operated and regulated by the Department of Conservation and Recreation in Virginia, the T. Nelson Elliott Dam plays a vital role in water resource management in the region. It is equipped with necessary safety measures, including an Emergency Action Plan, to ensure the safety of surrounding communities in the event of a potential breach. The dam's strategic location and design contribute to its ability to efficiently store and distribute water, making it a key asset for addressing the water needs of the area.
Overall, the T. Nelson Elliott Dam stands as a significant infrastructure project that highlights the intersection of water resource management and climate resilience efforts. Its role in providing a stable water supply underscores the importance of maintaining and monitoring critical infrastructure to meet the needs of growing populations and changing climate conditions. As a key component in the region's water supply system, the dam serves as a testament to the importance of sustainable water management practices in the face of evolving environmental challenges.

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 T. Nelson Elliott Dam
Where does the data for T. Nelson Elliott 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 High 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.
