Hydro Plant Levels & Flows

This information is updated every hour for river users near AEP's hydroelectric facilities. See plant locations.

Explanation of terms: The 'Forebay' and 'Tailwater' numbers show the elevation, in feet above sea level, of the water levels just upstream and downstream of the plants. 'Tailwater Flow' is the hourly average of the river flow just downstream of the plants, measured in cubic feet per second.
