As the mountain streams become warm, I'm getting good action fishing the sections of these streams up high below the mountain springs. The Appalachian Trail Club maps and books on the early settlers in the mountains can provide good information on the locations of this springs. These will cool the water downstream from the springs and provide good fishing. The Murray's Flying Beetle size 18 and a Mr. Rapidan Ant size 18 are excellent now.
Early this week most of the streams in the lower sections of the Shenandoah National Park were higher than normal for this time of year because of the heavy rains that went through the area. You will get your best fishing by coming into the streams from the Skyline Drive or upper reaches of the streams. My book Trout Fishing in the Shenandoah National Park covers all of these streams.
