When things don't work out trolling in the river,we stop and pick hellgrammites and stone cats in the riffles..My buddy doesn't know how to mug bait,so he fishes a jig below where I am picking bait.He always seems to get a few nice smallies.Also, when I'm wading I try to flip some rocks with my feet and stir up the bottom.Sometimes this starts the fish on a feeding frenzy,and they really turn on.
