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.

Well I'm going back up to Erie for more hot chrome. Leaving daybreak Wednesday and should be at the motel by noon and fishing by 1:00. Plan on fishing all day Thursday and Friday and going home by noon on Saturday. Couldn't get a room for Friday where I'm staying. Found a room in Erie for my possible Friday night stay. Kind of good as it is halfway between the two streams I like to fish.

Bring a raincoat and whatever you use that serves as a union suit. It's gonna be chilly/windy in the shale bowling alleys.. Additionally, if you do stay over Friday, there is the potential for enough snow to be problematic until you get to Meadville or so on the way back south and outta here. NWS is calling for the rain to change to all snow Friday night and while it isn't likely to amount to much of anything, we're in that time of the year up here where the usual margin for forecast error can be the difference between five total snow flakes and eight inches.

Just FYI...

I've been keeping an eye of on both NOAA and Weather Underground ever since I made my motel reservations on Sunday. I have a room for Wednesday and Thursday and another room for Friday in a different motel if I decide to stay over. Based on the report though (I saw the snow forecast and high winds) it is very unlikely I will stay over. More probably I will fish Friday until noon and head for home. If the fishing is as good as last week two full days will be plenty of action.

I have very good cold weather clothing and always bring a mid weight and heavy weight fleece pants and tops with me. I'l be bringing my heavier Gore-Tex rain jacket to protect me from any showers and cold wind.
