Fairfax Center Regional Swm Pond #D77 dam
Fairfax Center Regional Swm Pond #D77
Fairfax Center Regional Swm Pond #D77 is a key water resource infrastructure in Fairfax, Virginia, designed for flood risk reduction. Owned by the local government, this pond is regulated by the Department of Conservation and Recreation in Virginia. With a dam height of 26 feet and a storage capacity of 52.6 acre-feet, this earth dam structure plays a crucial role in managing stormwater and reducing flood hazards in the area.
Situated within the Baltimore District, Fairfax Center Regional Swm Pond #D77 has a low hazard potential and is assessed to be in satisfactory condition as of August 2021. The pond's inspection frequency is set at once per year, ensuring its operational effectiveness in flood risk mitigation. With a primary purpose of flood risk reduction, this infrastructure serves as a vital component of the region's water resource management system, contributing to the overall resilience against climate-related challenges.
Furthermore, the regional pond is equipped with emergency action plans to ensure swift responses in case of unforeseen events. With its strategic location and design, Fairfax Center Regional Swm Pond #D77 stands as a testament to proactive water resource management practices that are essential in the face of changing climate patterns. Enthusiasts of water resources and climate resilience can appreciate the importance of such infrastructure in safeguarding communities and the environment against the impacts of extreme weather events.
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 Fairfax Center Regional Swm Pond #D77
Where does the data for Fairfax Center Regional Swm Pond #D77 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 Low 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.
