Smallmouths are ambush feeders, so unless there’s a hatch they’re keyed into, these fish are less likely than trout to hold in open runs. With that in mind, avoid featureless areas and extreme shallows. When you get to the river, target structures like downed trees, submerged logs, boulders, pocket water, and underwater ledges. One other major difference between trout and smallies is productivity in frog water. Stretches of still water tend to be worth fishing for trout only when they are rising, but that’s not the case with bass. Slow-water trout have a lot of time to look at a fast-moving fly, which makes them difficult to fool on streamers. Smallmouths are more likely to charge than study, and the reedy edges of frog water make great ambush points. Whenever you hook a smallmouth near a prime ambush point, keep fishing that area for a while, because where there’s one, there are usually more.
