Operating Guide

What is an operating guide?

TVA uses operating guides for each reservoir to make decisions about moving water through its dams. These guides are based on many decades of operating experience. They are built around the idea of allowing seasonal variations in the use of flood storage space.

Operating guides take into consideration all the features that influence a reservoir’s ability to store and release water—the size and shape of the surrounding watershed, the reservoir’s surface area, and the average rainfall and runoff—as well as historical demands for water use and flood storage space at different times of the year.
