Tailings Pond Expansion Dam
Tailings Pond Expansion
Tailings Pond Expansion in Lexington, South Carolina, is a state-regulated structure with a low hazard potential and fair condition assessment. The dam, standing at 22 feet in height, was last inspected in April 2017 and is subject to regular inspections every five years. With a storage capacity of 449.2 acre-feet, the pond serves a crucial role in managing water resources in the area.
Located in Congressional District 02, South Carolina, Tailings Pond Expansion is overseen by the state regulatory agency, SC DHEC, ensuring that it meets all necessary permitting, inspection, and enforcement requirements. While the structure's primary purpose and associated structures are not specified, its significance lies in its role in water management and environmental protection. The expansion project represents a commitment to sustainability and responsible stewardship of water resources in the region.
As water resource and climate enthusiasts, it is essential to monitor and advocate for the safe operation and maintenance of structures like Tailings Pond Expansion. By staying informed about its condition, regulatory oversight, and emergency preparedness, we can contribute to ensuring the long-term viability and safety of water resources in Lexington, South Carolina. Initiatives to enhance risk management measures, update emergency action plans, and conduct regular risk assessments can further bolster the resilience of this critical infrastructure.

About Tailings Pond Expansion
Where does the data for Tailings Pond Expansion 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 below 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.

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.
