When I came down the canyon last night there was still a little color to the river, but it looked fine for fishing and was still clearing.
This report looks suspiciously similar to the previous report that was posted before all that mud came down. Even if that's the case, I suspect it's still fairly accurate.
From The River's Edge:
8/8 Spruce Moths! We can't keep this pattern in stock here at the shop. Dry fly fishing has been outstanding in the canyon with spruce moths. If you don't have any, try a large tan Elk Hair Caddis or any light color attractor dry fly. Even if you're not seeing the moths on the water, be certain the fish will still rise for them. Caddis, some PMD's and some smaller stones will pick up fish under the right conditions. General attractors and specialty soft-hackles always seem to be a hit as well. If you head all the way up into the park expect to find great fishing and fewer anglers on your next outing. Keep in mind that afternoon rains will frequently turn the river slightly off-color, so be prepared with a up-to-the-minute report. Enhance your success with light flourocarbon tippet and gentile presentations when you're out there and don't be afraid to fish slight variations of the above mentioned patterns. Stop in or give us a jingle before you go for the latest updates.
