Cedar Run Dam #3 dam
Cedar Run Dam #3
Cedar Run Dam #3, also known as Airlie Dam, is a crucial structure located in Fauquier, Virginia, along the Cedar Run river. Owned by the local government, this earth dam stands at a height of 55 feet and serves primarily for flood risk reduction and water supply purposes. With a normal storage capacity of 792 acre-feet and a maximum storage of 2513 acre-feet, Cedar Run Dam #3 plays a significant role in managing water resources in the region.
Managed by the Department of Conservation and Recreation in Virginia, this dam has a high hazard potential but is currently rated as satisfactory in its condition assessment. The last inspection in February 2020 deemed the structure to be in good shape. While the dam has not been modified in recent years, regular state inspections and enforcement measures ensure its continued safety and functionality. With a drainage area of 3.53 square miles, Cedar Run Dam #3 serves as a vital component of the region's water management infrastructure.
For water resource and climate enthusiasts, Cedar Run Dam #3 offers a fascinating glimpse into the complex interplay between infrastructure, regulation, and natural resources. As a key flood risk reduction structure in Virginia, this dam underscores the importance of proactive management and monitoring to ensure the safety and sustainability of water resources in the region. With its strategic location and critical role in water supply, Cedar Run Dam #3 represents a valuable asset for both local communities and the broader 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 Cedar Run Dam #3
Where does the data for Cedar Run Dam #3 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.
