First, what do we mean by tailwater? Tailwater is the water below a dam or other hydroelectric facility that is subject to changes in flow. The water is released at various rates and scheduled times in accordance with policies established by the US Government, but controlled by the local hydroelectric authorities.
Tailwaters have a constant temperature the year around and this is due to depth of the water in the impoundment. This fairly constant temperature allows the aquatic insects, bait fish, crustaceans etc, to flourish. Also many tailwaters will have a PH above 7.0 making them alkaline. Alkaline water will support huge hatches of caddis flies and midges providing the trout population with a stable source of food. This source of food allows the trout to grow very rapidly.
Usually, the trout found in tailwaters are larger, more active and provide a greater fight than the trout found in many creeks and streams. This is due to both the food supply and high dissolved oxygen level of the water.
The Southeastern states are blessed with an abundance of hydroelectric dams providing economical electricity. In addition, these dams provide some of the very best trout fishing. In recognition of that, we at the Trout University have assembled three great fly collections to fit any budget. These collections are now available!
