Did you get a permit?
Nobobdy hunts there anymore, its too crowded. LOL sorry for the Yogi Berra routine but it may be true. When I first moved here in 1998 I hunted it when the TVA managed the property by giving out 2-day weekend hunt permits for four designated hunting weekends. The permits were limited to 50 hunters for each 2-day hunt and at times that seemed like too many people in the woods. However I never had a problem getting permits for all 4 hunts every year and I killed some very nice deer.
Then, one year I believe maybe 2003, the Tennessee Outdoors magazine wrote an article about how great the place was and the TVA was overwhelmed with hunt applications the next year. I think the year after that they threw in the towel and let the TWRA manage the permit process as a WMA and that is all she wrote.
Now don't get me wrong, the place was and likely still is infested with deer and turkeys. However it does not appear that the TWRA limits the permits they issue so clearly the week days are when you need to be there. I won't give you any tips on the open forum, but its worth your while to give this place a try. Note that there is a shooting range within the gated boundaries of the steam plant itself and this is an off limits area. The deer absolutely swarm the range during the hunting season, sometimes to the extent you have to stop shooting since they are protected in that area.
