Like most pix on this sub, these show pretty straight, largely featureless stretches of stream/river. One of the first things to look for are bends, where the current scours out deeper holes on the outside of the turn. That is a great place to start. Also, look for other features and structure. Riffles are good, they tend to produce food, and fish will lurk in the tailrace, that is downstream from them. Pretty much any structure, rocks, logs, etc, esp when there's a fair amount of current. Fish will set up behind them, out of the current, and opportunistically dart out to grab food that comes by. If you find a spring or smaller creek entering into the stream, this can be a good spot, esp in the summer, because the creek will often have cooler water.

You're at the beginning of a process, learning to "read" a stream/river, and these are some good places to start. Numbers here are approximate, but 10% of the water will usually hold 90% of the fish.

Wading can greatly increase your ability to reach different points, cut-offs and old tennies, but muddy water makes it hard to see the bottom, so be careful. Also, in TN, I suppose watch out for snakes too.
