Clemson Lower Diversion Dam - Saddle Dike dam
Clemson Lower Diversion Dam - Saddle Dike
The Clemson Lower Diversion Dam - Saddle Dike is a critical component of flood risk reduction efforts along the Seneca River in South Carolina. Constructed in 1961 by the US Army Corps of Engineers, this earth dam plays a vital role in preventing Lake Hartwell from flooding the lower elevations of Clemson University. The dam features subsurface concrete cutoff walls and seismic shear walls to mitigate seepage issues and provide stabilization during potential earthquakes. While the Upper and Lower Diversion Dams have a low risk of failure, the Saddle Dike is considered to have a moderate risk due to the potential for seepage-induced erosion of foundation soils.
USACE is actively managing the risk associated with the Saddle Dike by continuously updating the Emergency Action Plan, conducting emergency exercises, and performing regular inspections and maintenance. The pumping station, part of the flood control system, has a small flood risk during heavy rain events that exceed its capacity. Although flooding in low-lying areas of Clemson University may occur, the slow filling nature of the inundation provides time for safe evacuation. USACE collaborates closely with local and state emergency managers and Clemson University personnel to ensure effective risk management measures are in place to protect the campus and surrounding areas.
Overall, the Clemson Lower Diversion Dam - Saddle Dike is a key infrastructure ensuring flood resilience for the region. Through proactive risk management practices and collaboration with stakeholders, USACE is working to safeguard the dam and surrounding areas from potential flooding incidents, highlighting the importance of ongoing monitoring and maintenance to ensure the safety and security of the community.

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 Clemson Lower Diversion Dam - Saddle Dike
Where does the data for Clemson Lower Diversion Dam - Saddle Dike 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.
