About this dam

Lee Nuclear Dam 4

Lee Nuclear Dam 4, located in Cherokee, South Carolina, is a crucial water resource infrastructure owned by a public utility. This dam, regulated by the South Carolina Department of Health and Environmental Control, spans across the Broad River and stands at a height of 65 feet with a storage capacity of 3000 acre-feet. With a fair condition assessment and low hazard potential, it plays a significant role in water management and conservation in the region.

Constructed with an earth core and stone foundation, Lee Nuclear Dam 4 serves multiple purposes beyond hydroelectric power generation, making it a versatile structure for water resource management. Despite its age, the dam has been regularly inspected and maintained to ensure its structural integrity and operational efficiency. With its location in the Charleston District and oversight by state regulatory agencies, the dam continues to play a vital role in water supply and flood control measures in the area.

As a key component of the water infrastructure in South Carolina, Lee Nuclear Dam 4 provides essential services for the local community and beyond. With its low hazard potential and fair condition, the dam stands as a reliable resource for water management and climate resilience efforts. As climate change continues to impact water resources, dams like Lee Nuclear Dam 4 play a critical role in ensuring sustainable water supply and mitigating the effects of extreme weather events on the region.

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.

FAQ

About Lee Nuclear Dam 4

Where does the data for Lee Nuclear Dam 4 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.
