Mount Airy City Lake Dam dam
Mount Airy City Lake Dam
Mount Airy City Lake Dam, also known as Tumbling Rock Reservoir, is a local government-owned structure located in Surry County, North Carolina. Built in 1911, this earth dam serves the primary purpose of debris control along the Lovills Creek-Tr river system. With a hydraulic height of 22 feet and a structural height of 29.5 feet, the dam stands at a total height of 30 feet and spans 280 feet in length.
The dam has a storage capacity of 130 acre-feet, with a maximum discharge of 660 cubic feet per second. Despite being classified as having a low hazard potential, the dam is in fair condition as of the last inspection in 2012. The surrounding area covers 4 acres with a drainage area of 706 acres, making it a vital component of the local water resource management system. Although not regulated by the state, the dam undergoes regular inspections to ensure its safety and functionality for the community of Mt Airy.
Overall, Mount Airy City Lake Dam plays a crucial role in protecting the surrounding area from debris and maintaining water resources in the region. With its long history and essential function, this dam is a significant structure for water resource and climate enthusiasts interested in the management and conservation of water systems in North Carolina.

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 Mount Airy City Lake Dam
Where does the data for Mount Airy City 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.
