" Brook trout are easy to fool, and are found in places on most rivers and streams that are easily reached: big pools, soft riffles, along undercuts, and under overhanging trees. Mostly though, they are found in soft, deep water, tend to feed lower down on the water column, and are less likely to take surface flies. "
