The mountain trout streams are cold and the trout are not feeding aggressively. However, if you drift a Murray's Olive Strymph size 10 right in front of them, there might be chance you can catch them in the deepest pools.
As always be sure to check the road openings/closures of the Skyline Drive by calling 540-999-3500, option 1, option 1.
I will be conducting a 2 hour workshop on the Shenandoah National Park Streams this Saturday, February 1 from 10a.m. to noon at the fly shop in Edinburg Va.
