Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

As far as I can tell, this species has only previously been reported from one site in Oregon along the Columbia gorge. However, the key characteristics are fairly unmistakable in all except for one minor detail:
— 4 small yellow spots on frons visible in photos
— Narrow occipital spinule row curves forward (but doesn’t quite meet on stem of ecdysial suture, as it's supposed to in this species)
— Short spinules on anterior margin of front legs
— Short rposterior row of blunt spinules on abdominal tergae, rather than elongated spinules dorsally
I caught several of these mature nymphs in the fishless, tiny headwaters of a creek high in the Wenatchee Mountains.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

I picked up Kelly Galloup's nymph indicator line to match the 10.5' 7wt single hand fly rod I use for Steelhead. The rivers I fish don't allow much room for back casts, so roll casts are the norm. I fish nymph/egg patterns under an indicator about 90% of the time. I have been looking online to find a leaded formula for this setup, but with no luck.... Does anyone have a "Leader Formula" for such a setup?? I would like to tie my own...

I fish pretty much exclusively trout beads and nymphs under an indicator for Great Lakes steelhead and have no trouble roll casting 40' - 45' with one or two BB's, a fly or two, and the indicator. I use an off the shelf Rio 7.5' 3X to which I tie a tippet ring and 2' of 4X. I think the line selection is far more important than the leader. I use SA WF#7F Nymph/Indicator with a 10' rod.

Matt, what rod are you using?
