Sweetwater Lane Dam dam
Sweetwater Lane Dam
Sweetwater Lane Dam, located in Loudoun, Virginia, is a privately owned structure regulated by the Department of Conservation and Recreation. Situated on the Bull Run un-named tributary, this Earth-type dam stands at a height of 20 feet with a length of 420 feet. With a storage capacity of 63.4 acre-feet and a normal storage of 35.9 acre-feet, the dam serves purposes beyond just flood control or water supply.
Although the hazard potential and condition assessment of Sweetwater Lane Dam are currently listed as undetermined and not rated, respectively, the dam is subject to regular inspections and regulatory oversight by the state of Virginia. As a crucial component of the local water infrastructure, it plays a significant role in managing water resources in the area. Despite the lack of information on its construction year or recent modifications, its presence is essential for the surrounding community's water management needs.
While specific details such as spillway type, drainage area, and risk management measures are not provided for Sweetwater Lane Dam, its strategic location and role in water storage indicate its importance in the overall water resource management of the region. With its notable storage capacity and state-regulated status, this dam serves as a key asset in maintaining water supply reliability and addressing potential water-related challenges in the area.
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 Sweetwater Lane Dam
Where does the data for Sweetwater Lane 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 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.
