Mirror Lake Dam dam
Mirror Lake Dam
Mirror Lake Dam, located in Catawba, North Carolina, is a privately owned earth dam completed in 2007 for recreational purposes. With a hydraulic height of 29.7 feet and a structural height of 33.3 feet, the dam stands on the North Fork Mountain Creek - Tr, offering a serene and picturesque setting for water resource and climate enthusiasts to explore. The dam has a storage capacity of 191 acre-feet, with a normal storage level of 128 acre-feet and a surface area of 13.8 acres.
Despite its high hazard potential, Mirror Lake Dam is currently assessed to be in fair condition as of the last inspection in December 2019. The dam is regulated, permitted, inspected, and enforced by the North Carolina Department of Environmental Quality's Dam Safety Program, ensuring its safety and compliance with state regulations. While the dam does not have a spillway or outlet gates, its associated structures are minimal, reflecting its primary purpose of providing a recreational oasis for visitors to enjoy. Overall, Mirror Lake Dam serves as a vital infrastructure piece that harmoniously integrates with its natural surroundings, offering a tranquil escape for those interested in water resources and climate conservation.

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 Mirror Lake Dam
Where does the data for Mirror 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.
