The Murray's Magnum Streamers are exceptional for bass fishing at this time of the year. The streams are starting to cool at night so the bass are going deeper. The Magnum Creek Chub, Magnum Hog Sucker, and Magnum Darter all in size 4 will cover your needs. These represent the natural foods the smallmouth are feeding on. Fish these on a 2X Leader. I have had some customers going to a sinking Fluorocarbon leader. Fan your casts over the whole stream and strip it 6 inches every 5 seconds.
The North and South Fork of the Shenandoah River are clear and fishable. For access information stop by the fly shop to look at our master map or see my book Virginia Blue Ribbon Streams.
