2 days ago I did a kick and found many large trico nymphs that looked like they were ready to pop, and even saw a few adult tricos in the air. This morning there was a full on hatch! It was a sight for sore eyes, and the resulting hatch made for some excellent morning fishing.
The money fly was a size 22 Flashback Barr's Emerger bwo, which does a decent job of also imitating an emerging trico in 11 MC. However, around 9:30 am the wind picked up and didn't let to many bugs hit the water, so I didn't get to see how eager the trout would be to feed on the spinner fall at 300 c.f.s. There were a few fish rising sporadically, but I think it's a little soon for the truly great dry fly fishing we associate with the trico hatch. Don't worry that time is coming soon!
There are still a few caddis flying around, and even some pmds coming off around lunch time, but again, few fish rising to them. That doesn't mean that a well placed size 16-18 bead head pheasant tail or bead head Barr's Emerger in a pmd flavor won't fool a fish... We were using 5x tippet to our first fly (san juan worm), and 6x tippet to our dropper (Barr's Emerger bwo). Our indicator was set at a depth of 6 feet from our first fly, with enough weight on our leader to cut through all this fantabulousness water we have in our rivers. 3 number 4 size split shot about 16 inches above your first fly should do the trick.
