Can someone tell me why they levels are so low from fall till spring? I live in East Tennessee and have asked many people but no one can tell me why

Evaporation, may be draw down to help with snow and spring rains to help prevent flooding.
Maybe?
Maybe?

^^^^^ this ^^^^^
Yep, it's drawdown for spring rains, plus, they do maintenance on the dam and other things in the winter and all this is to have less interference with the lake users in the summer.

Ok that makes sense but has to be really hard on the fish also I could see doing it every 5 years or so but every year. We don’t get that much rain or snow

Dams overflow or break if you underestimate the amount of rain or snow. That makes it really hard on people downstream and fish don't vote.

Douglas, Norris and Cherokee lakes are the upper lakes in the TVA system. Lake levels are lowered in fall to help in reducing flooding in the TVA system. These lakes can be used as storage when we have large rain or runoff events. Lake levels start rising in April. TVA has a great web site coveting all their lakes.

These lakes, Watauga, South Holston, Boone, Cherokee, Douglas and Norris, are flood control lakes. They are also power generating but mostly designed for flood control. Makes the fishing very challenging during a 40 ft draw down.
