Caddis hatches have been strong everywhere I fish for the last several (many?) years and I've noticed a lot more stoneflies in early spring on several NW regions streams. I'm not talking about the little microscopic black stones, but the larger black and brown ones that can be mistaken for caddis in flight by novice anglers.
All the other hatches have been about the same, which is to say they aren't worth getting too excited about beyond being prepared if you do encounter them.
I've been at this long enough to say that beyond caddis, sulphurs, and maybe BWO's, there are few other hatches worth discussing except in specific locations. March Browns, Slate drakes, and tricos would be the bulk of that later category.
Our habitat and water quality, across the board, is just not that great. Even in streams that hold good numbers of wild fish, the classic hatches are often sparse and unpredictable. The other consideration, IMO, is that too much emphasis is placed on fishing hatches that are the perfect storm of large numbers of bugs, ideal water condtions, and receptive fish. Most hatches are a trickle of bugs over several days with no promise of triggering a heavy feeding response.
Fish when water conditions are good. Have a solid selection of flies that can cover many different situations, and catch fish when they are willing to eat.
