Reston Section 43 Swm Facility dam
Reston Section 43 Swm Facility
The Reston Section 43 Swm Facility, also known as Reston Sugarland, is a private stormwater management facility located in Fairfax, Virginia. Owned by a private entity, this facility plays a crucial role in flood risk reduction along the Sugarland Run tributary. With a dam height of 26 feet and a storage capacity of 180 acre-feet, it serves as a vital infrastructure for mitigating flood risks in the area.
Managed by the Department of Conservation and Recreation in Virginia, the Reston Section 43 Swm Facility is designed primarily for flood risk reduction but also serves recreational purposes. Its strategic location and design make it a key player in safeguarding the surrounding areas from potential flooding events. With a storage capacity of 180 acre-feet and a surface area of 7.51 acres, this facility is equipped to handle stormwater runoff effectively.
Although the hazard potential and condition assessment of the facility are currently undetermined, its presence and functionality are crucial for the community's resilience to climate-related challenges. As climate change continues to impact water resources and weather patterns, infrastructure like the Reston Section 43 Swm Facility will play a vital role in ensuring the safety and well-being of residents in Fairfax, Virginia.
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.
Plan around the weather

About Reston Section 43 Swm Facility
Where does the data for Reston Section 43 Swm Facility 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.
