Fair Lakes Land Bay 2 Swm Bmp Pond Dam
Fair Lakes Land Bay 2 Swm Bmp Pond Dam, located in Fairfax, Virginia, plays a crucial role in flood risk reduction along the Big Rocky Run tributary. This earth dam stands at 21 feet tall and stretches 683 feet in length, providing a storage capacity of 56.1 acre-feet to help manage water levels in the area. The dam's primary purpose is flood risk reduction, with a high hazard potential but a satisfactory condition assessment as of the last inspection in January 2021.
Managed by the Department of Conservation and Recreation in Virginia, Fair Lakes Land Bay 2 Swm Bmp Pond Dam is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and effectiveness. While specific details about the dam's construction year and spillway type are not provided, its location and capacity make it a critical infrastructure for water resource management in the region. With a dedicated emergency action plan and regular inspections, the dam serves as a key component in mitigating flood risks and protecting the surrounding community from potential water-related disasters.
Overall, Fair Lakes Land Bay 2 Swm Bmp Pond Dam stands as a vital structure in the flood risk reduction efforts in Fairfax County, Virginia. With its significant storage capacity and state-regulated operations, the dam plays a crucial role in managing water levels along the Big Rocky Run tributary. Its satisfactory condition assessment and adherence to safety guidelines highlight its importance in protecting the community from potential water hazards and ensuring sustainable water resource management in the region.
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 Fair Lakes Land Bay 2 Swm Bmp Pond Dam
Where does the data for Fair Lakes Land Bay 2 Swm Bmp 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 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.
