A lot of folks have been asking if the fishing will be worthwhile this weekend, given the rain we're seeing. The short answer, is yes, as long as you play it safe. Rivers and streams will rise, as a general .75-1" is expected across many portions of WNC on top of the rainfall we've already picked up. I highly doubt the Davidson will spike to 3,000 cfs, or Wilson Creek will be completely blown out, but there will be plenty of water to contend with. Periodically check the water levels here. 

More water means streamers, large nymphs, and heavier tippet will serve you well (in most places). Try a San Juan Worm, Squirmy Wormie, Ooey Gooey Grub, Vinyl Rib Stone, or an egg pattern on 4x. If you're failing to hook up, don't immediately change your pattern, but tie on a smaller size. Anglers tend to initially reach for the larger sizes, because they're more visible (I'm guilty!). Usually it's a fly that's too big that strays fish away, not necessarily the pattern itself. Try a dropper. Tie on a larger, heavier nymph, such as a stonefly. This will act as your lead fly and will get both flies down to the bottom. Tie on a smaller fly behind your lead fly. A lot of times, the larger stone will attract a trout's attention only for the fish to settle for the smaller pattern trailing behind.
