River fishing can be frustrating because a lot of times, EVERYTHING looks good. Trees here, ledges there, boulders somewhere else.
Before getting into one of the tournaments, make sure to do your homework and some prefishing in that area. Talk to some of the locals you see in the area. While most may not tell you anything, there is always that chance someone will.

Good job.
