Just as an additional thought..
Setting the question of flow rates momentarily aside and looking at where the bass will be..
This will often depend upon what time of year it is and water temperatures. This time of year, the fish will almost alwasy be in the deeper, slower water where they don't have to expend much energy. They're getting ready for winter.
However, in high summer and particularly when water temps are pretty high (say up around 80 or so) it can be surprising how many of the good fish will lay in or very near to the heaviest water in the creek in search of sufficient oxygen. They won't lay right out in the heaviest water, but if there is a pocket of any size (even the size of a coffee table picture book) of slack water immediately adjacent to the heavy flow, this (in large creeks/small rivers anyway) will often be where some of the best fish will be. I've caught lots of nice bass out of water you'd think would wash the scales right off them. Just so long as there is the tinyest of pockets for them to utilize as a resting place.
