At this time of the year the bass are holding in the 10 to 15 ft deep water upstream of Chapman's Dam (#5, also known as M on page 11 of my Virginia Blue Ribbon Streams book) on the North Fork of the Shenandoah River. On the South Fork of the Shenandoah this deep water can be found above the Luray Reservoir. You can put your boat in at Massanutten Landing (#26, also known as J on page 11 of my book) and float down to the Reservoir. The Sonar Sink 30 Clear in the 200 grain fly line will help you get your flies down deeply. The Murray's Tungsten Cone Head Marauders in size 4 stripped 6 inches every 10 seconds along the stream bottom is very effective in these conditions.
