Earlier this week I went to several mountain trout streams and found the conditions to be tough. The water levels are low and the water temperature was running around 65 degrees. Therefore the trout are wary and not feeding as actively as they were several weeks ago.
Many years ago, Richard Parks suggested I try a purple dry fly as we floated the Yellowstone River. Although I laughed at him, we caught many trout on them. So this week, I tried the Murray's Purple Dun size 16 on the mountain streams. I had success with that and the Murray's Flying Beetle and Mr. Rapidan Ant size 16. Use a Mountain 6ft 6X Leader or a Classic 7 1/2ft 6X leader.
All of the Shenandoah National Park streams are low and clear. The Hughes, White Oak, and Rose River will give you a little better water level. Watch your approach and sneak, sneak, sneak. For more information on the Park streams along with access, check out my book Trout Fishing in the Shenandoah National Park.
