Sleeter Lake Dam dam
Sleeter Lake Dam
Sleeter Lake Dam, located in Loudoun, Virginia, is a privately owned structure with a primary purpose of irrigation. This earth dam, standing at a height of 55 feet and a length of 1100 feet, regulates the flow of North Fork Goose Creek. With a storage capacity of 3159 acre-feet and a surface area of 120 acres, the dam plays a critical role in providing water for irrigation and recreation in the area.
Despite its satisfactory condition assessment, Sleeter Lake Dam poses a high hazard potential. The Department of Conservation and Recreation in Virginia regulates and inspects the dam periodically to ensure its safety and structural integrity. The last inspection, conducted in June 2020, deemed the dam to be in satisfactory condition. With a history of serving its primary purpose effectively, the dam stands as a vital water resource management structure in the region.
As a significant feature in the water resource infrastructure of Loudoun County, Sleeter Lake Dam serves as a crucial component for water management and conservation efforts in the area. Owned privately, the dam not only facilitates irrigation but also provides recreational opportunities for the local community. With its impressive storage capacity and strategic location, Sleeter Lake Dam remains a key player in sustaining the water resources of the region while being subject to rigorous regulatory oversight and maintenance to ensure its continued functionality and safety.

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
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Sleeter Lake Dam
Where does the data for Sleeter Lake 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.
