Mirror Lake Dam dam
Mirror Lake Dam
Mirror Lake Dam, also known as Reflections Dam, is a privately owned structure located in Richland, South Carolina. Built in 1940, this Earth-type dam stands at a height of 9.2 feet and has a length of 420 feet, creating a reservoir with a storage capacity of 85 acre-feet. The primary purpose of Mirror Lake Dam is for recreation, offering visitors a serene spot for activities like fishing and boating on its 18.3-acre surface area.
Despite its fair condition assessment and high hazard potential, Mirror Lake Dam is regulated and inspected by the South Carolina Department of Health and Environmental Control (SC DHEC). The dam is situated on TR-Mill Creek and falls under the jurisdiction of the Savannah District of the U.S. Army Corps of Engineers. Congressman James E. Clyburn represents the district where the dam is located, highlighting the importance of water resource management and climate resilience in the region.
With a history dating back over 80 years, Mirror Lake Dam remains a vital component of the local landscape, providing both recreational opportunities and essential water storage capacity. As climate change continues to impact water resources, maintaining and monitoring dams like Mirror Lake Dam is crucial for ensuring their safety and resilience in the face of evolving environmental conditions.

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.
