Granted I haven't trout fished in years and never on the Cumberland River, but where I grew up in Eastern Ky, I used to tie on a small barbless hook under a very thin stick bobber and just float them. Adjust ur length based on depth and try to have them just off the bottom. Now I fished in small streams so not sure this would work there. Typically the current carried the bobber and when the bobber stopped, I had a fish. Just an idea. Not sure what the current is like there so may not be an option.
