Summer Cat I Emergency Cooling Water dam
Summer Cat I Emergency Cooling Water
Summer Cat I Emergency Cooling Water is a crucial public utility structure located in Jenkinsville, South Carolina. Built in 1979, this Earth-type dam stands at a height of 113 feet and has a storage capacity of 1600 acre-feet. Despite being regulated by the Nuclear Regulatory Commission, this dam is classified as having a low hazard potential and satisfactory condition assessment.
Situated on the Frees Creek, this dam serves as emergency cooling water for nuclear facilities in the area. With a surface area of 44 acres, this structure plays a vital role in maintaining the safety and efficiency of the surrounding nuclear infrastructure. Although it has not undergone recent modifications, regular inspections are conducted to ensure its continued functionality.
Managed by the US NRC, Summer Cat I Emergency Cooling Water is a critical asset in the region's water resource management and climate resilience efforts. With its moderate risk assessment rating and strategic location within the Savannah District, this dam serves as a key component in the area's emergency response and disaster preparedness plans. Its presence underscores the importance of sustainable water infrastructure in safeguarding against potential climate-related challenges.
Dam data reference
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 Summer Cat I Emergency Cooling Water
Where does the data for Summer Cat I Emergency Cooling Water 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.
