// Strategic Significance

Hartwell Dam on the Savannah River on the South Carolina-Georgia border creates Lake Hartwell — one of the largest reservoirs in the Southeast covering over 56000 acres. The dam provides flood control water supply and hydroelectric power for the Piedmont Carolinas region. Hartwell is part of a three-dam system on the Savannah River along with Richard Russell Dam and Thurmond Dam downstream.

// Civilian Impact Assessment

A Hartwell Dam failure would send flooding down the Savannah River through Richard Russell Dam and Thurmond Dam potentially triggering a cascade failure. The cascading flood would ultimately reach Augusta Georgia and Savannah Georgia. The Savannah River nuclear site downstream adds radioactive contamination risk from a major flood cascade through the system.

// Evacuation & Shelter Guidance

Savannah River communities from Hartwell Dam downstream through Augusta Georgia should know dam failure inundation zones. A cascade failure through all three Savannah River dams would be catastrophic for Augusta. Monitor Army Corps Hartwell Dam safety reports and South Carolina SCEMD broadcasts. Savannah River nuclear site emergency protocols would interact with dam failure emergency planning.
