River Flows for Hydro Plants

You may track, on an hourly basis, water levels and flows of the recreational rivers and lakes near AEP's hydroelectric facilities. See a map of our plant locations.

Explanation of terms

  • The "Forebay" and "Tailwater" numbers show the feet above sea level of the water levels immediately upstream and downstream from our plants.
  • "Tailwater Flow" is the hourly average of the river flow just downstream of the plants, measured in cubic feet per second.
