Rick Boulin ties proven trout flies, such as a black woolly bugger and Patuxent Special on unpainted 1/8-ounce jigheads to create effective bottom bouncing lures. Two-inch grubs could also be used. Marty Gudenius has been taking Gunpowder trout for years with tiny trout/crappie marabou jigs in black, white, yellow, or olive on spin or fly tackle. Spin fishermen can also fish some of the most effective fly patterns. Use a clear spin bubble, 1/2 inch in diameter, or a slim "European" style river float above one or two beadhead nymphs, such as size 14 Prince, Gold-ribbed Hare's Ear, Pheasant Tail or San Juan Worm. You may need to add a small split shot, preferably between the flies.
