Upper River:
Things have really warmed up and the snow is mostly gone in the area. The Box Canyon boat ramps are open, however the river is very low, so tread carefully. The best fishing will be with nymphs and streamers. Try a size 6 black Pat’s Rubberlegs with a size 18 black or tan zebra midge. On a cloudy day it never hurts to strip a streamer. I like a size 4 Olive Sculpzilla in the Box Canyon. The river at Last Chance can fish good as well, there has been some Mother’s Day Caddis hanging around, so you might see some fish up in the afternoon. Try a size 16 EZ Caddis or a size 18 Spent Partridge Caddis in peacock. It also never hurts to drop a Lawson’s Partridge Caddis Emerger size 18 tan or olive below your dry.
