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.

Hopefully some of you have had better luck than me getting to a river this week. I spent the past 4 days in Ohio (the worst place on this planet to spend warm spring days during the start of hatch season) and am starting to develop a twitch now that it's going on a week of no fishing.(and it's not looking good for me until at least mon.....damn family obligations)
So I would like to here some reports if you have any, and what the bug situation looks like. Has this warm weather brought about any early march brown sightings from the central pa boys.

actually hit spring creek today after class, caught like 10 or 11 and must have missed 5-6 more, but most were little 4-5 inch dinks, being in state college sure does have its advantages fishing-wise. there were quite a few fish rising, I thought it was caddis but Im not sure, nymphing was the way to go today, those little trout absolutely smashed a small pheasant tail

caught a lot of tiny trout (4-5 inches) these ones were the trophies of the day lol

That looks like a beautiful little stream. No covered bridges on the streams I fish here in Wisconsin.

High, fast, and Muddy here so the fishing is not so great. Looks like a couple more days of rain so it may be a while before its any good. The hatch(BWO's?) that was happening today would have made for a fun day if the water had been better. I spent most of the time on the river just watching the insects and birds.

looks like you had a good time on spring I have to get back up there soon.

Any day spent on high muddy water is still better than a day spent in Ohio. (If we have an Ohio contigent here please feel free to P.M. and I will stop my relentless attacks...no hard feelings)

Hello everyone;
Just spent yesterday driving to some new water on the Clark Fork river in MT. I found that it was not the day to go downstream as the recent snow melt had turned the normal light green water into something that resembled a cup of espresso with about a foot of visibility. However, it was just too nice of a day to sit at home. So my wife and I hit the water with little success save for a few nice twigs and a couple of submeged logs. The whole trip every place we stopped there were caddis coming off in fishable numbers and quite a few skwala nymphs clinging to everything (and here is the but) nothing rising and no lined tigtened. I figured that I just missed a great skwala hatch and that the caddis just threw me off what was really going on. That is fishing, we will dilligently pursue the trout of on our nearby streams. Tomorrow is another day.
The landscape on the other hand did not disspoint with snow still clinging to the mountain tops all around, and the western meadolarks and robins singing for us it did make the day pleasant. Even saw a bald eagle so all in all a good day spet in the outdoors made humbling by the trout all ready full bellies.

I have enjoyed a wonderful blue quill/adoptiva hatch here in n. westchester, new york over the past ten days or so on a number of streams in the croton river watershed. probably will be replaced by subvaria pretty soon. pics from another post

I am haunted by waters
