When autumn days feel more like winter, go subsurface. Hare’s Ears, Pheasant Tails, Princes, beadhead or weighted, do well. In the shrunken currents of fall, fishing without a strike indicator gives more precise control in the narrow drift lanes. But this requires that you get close to the fish. Look for pocket-water seams, slots, and current tongues that run knee-deep or better. The surface chop will help mask your approach, but keep low, move slowly, and use the cover of boulders and brush for concealment.
