Lewiston sits at Idaho's lowest elevation at the confluence of the Snake and Clearwater rivers — the head of navigation for ocean-going vessels traveling up the Columbia-Snake River system. The river confluence creates flooding risk, and surrounding steep canyon terrain has experienced wildfire multiple times. Lewiston shares the Lewiston-Clarkston metro with Clarkston, Washington, creating cross-state emergency coordination needs.
