// Strategic Significance

Dardanelle Dam on the Arkansas River impounds Lake Dardanelle adjacent to Russellville — the cooling water source for Arkansas Nuclear One, the state's only nuclear power plant. The dam is a US Army Corps of Engineers lock-and-dam structure that is part of the Arkansas River Navigation System. The intersection of a major dam and nuclear plant cooling water dependency makes this a uniquely compounded infrastructure risk point. Loss of Lake Dardanelle as a cooling water source would directly affect ANO operations.

// Civilian Impact Assessment

Russellville sits between Arkansas Nuclear One and Dardanelle Dam — two significant infrastructure facilities. Residents are within the Arkansas Nuclear One Emergency Planning Zone and should have pre-planned responses to both nuclear plant alerts and dam incident scenarios. The Arkansas River corridor downstream would face severe flooding in a dam failure scenario.

// Evacuation & Shelter Guidance

Russellville residents should know their EPZ zone status relative to Arkansas Nuclear One. For dam-related events, follow Yell County and Pope County Emergency Management directions. Move to high ground away from the Arkansas River in any dam emergency.
