Alsup Lake Dam dam
Alsup Lake Dam
Alsup Lake Dam, located in Winston-Salem, North Carolina, is a privately owned earth dam that was completed in 1952 for the primary purpose of recreation. The dam stands at a hydraulic height of 21 feet and a structural height of 24 feet, with a length of 350 feet. It has a maximum storage capacity of 50 acre-feet and a normal storage of 42 acre-feet, covering a surface area of 5.2 acres. The dam is situated on Muddy Creek-Tr and is under the jurisdiction of the Huntington District of the US Army Corps of Engineers.
Despite being deemed low hazard potential, Alsup Lake Dam has been inspected and found to be in satisfactory condition as of January 2014. It is not regulated by the state and does not require permits for operation. The dam has not undergone any modifications in recent years and does not have an Emergency Action Plan (EAP) in place. While the dam is not associated with any federal agencies for funding, design, construction, or regulation, it continues to serve its purpose of providing recreational opportunities for the community.
Alsup Lake Dam serves as a vital component of the local water resource infrastructure, providing recreational amenities while also helping to manage water flow along Muddy Creek. With its low hazard potential and satisfactory condition, the dam remains a stable and reliable structure within the region. As water resource and climate enthusiasts, it is crucial to monitor and support the maintenance of dams like Alsup Lake Dam to ensure the safety and sustainability of our water systems.

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 Alsup Lake Dam
Where does the data for Alsup 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 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.
