Mission Lake Dam dam
Mission Lake Dam
Mission Lake Dam in Lexington, South Carolina, stands as a testament to early 20th-century engineering, completed in 1900 with a primary purpose of recreation. This private earth dam, with a height of 15 feet and a length of 300 feet, impounds the waters of TR-Savany Hunt Creek, creating a surface area of 12 acres and a storage capacity of 101 acre-feet. Despite its age, the dam is deemed to have a low hazard potential and fair condition, with inspections conducted every five years to ensure its safety.
Owned and regulated by the South Carolina Department of Health and Environmental Control (DHEC), Mission Lake Dam serves as a vital component of the local water resource infrastructure. Its uncontrolled spillway and buttress core provide effective flood control measures, while also offering recreational opportunities for the surrounding community. With a risk assessment rating of moderate, efforts are in place to manage any potential risks and ensure the continued safety and functionality of the dam for both water resource and climate enthusiasts alike.
As climate change continues to impact water resources worldwide, the significance of maintaining and monitoring dams such as Mission Lake Dam becomes increasingly crucial. With the Savannah District of the US Army Corps of Engineers overseeing its operations, this historic structure not only contributes to water management efforts but also serves as a reminder of the intersection between human ingenuity and environmental stewardship in the face of evolving climate challenges.

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 Mission Lake Dam
Where does the data for Mission 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.
