I was just in Basalt and had a great time. There were PMDs and green drakes coming off mid-day when I was there. I spent a half day fishing a small stream in the back country for cutthroats (I included a pics of the stream and one of the many cutties). I planned more back country stuff, but the dry fly fishing on the Pan was too good to walk away from. I didn't fish the Fork either, the Pan was just fishing too well! The Pan was a bit crowded (I took a shot of the crowds), but well worth it if you stayed away from the most famous pools or spots right by a pullout. Stop into Taylor Creek Fly Shop, that place is great and the guys there were very helpful.
I had three full fishing days. The first day was nice. The second and third days were rainy and overcast. I caught a ton of fish. I had great dry fly fishing with the PMD, BWO, and green drake hatches. I caught a few on midges in the morning too.
I saw a ton of fish rising each day. They are fished over hard and well educated. The strange thing was that I never put a fish down. Instead, if a fish realized the fly was a fake, it would just let the fly drift by and then take a natural right after the fly passed. I moved a lot of fish that aggressively came up to eat and refused the fly at the last moment. If you have the discipline to let the fly continue to drift, the fish might come back around and eat. I caught a few fish this way, but its hard not to strike when the fish acts like its taking the fly.
Have a great time!
Here are a few pics from my trip.
