The native brook trout streams in the Shenandoah National Park are low and clear. We have not had rain in several weeks and the streams are showing it. The best sections of these streams will be within a mile when you hike in from the lower boundaries. Until we get some rain, I wouldn't recommend coming in from the top of these streams.
From early afternoon until dark, I have seen trout feeding on natural whitish moths in the back eddies and in the slow currents along the sides of the streams. Fish a Murray's Moth size 14 or 16 in these areas, experimenting with a dead drift and a slow twitching action. The Murray's Flying Beetle size 16 and Murray's Inchworm size 14 have been productive this last week. Fish these on a Classic 6X Leader. Last tip for this week--if you have to go to your hands and knees to hide your approach and keep from scaring the trout--then go to your hands and knees.
