I haven’t hit a “good” Sulphur hatch on Spring in probably 5 or 6 years. My last “good” Sulphur hatch on Spring was that rainy, drizzly day on Jam weekend a few years ago where they rose all day like morons and everyone caught like 1000, or something silly like that. Anyone who was there I’m sure remembers it, as everyone I talked to had their best day ever on Spring that day.
Maybe they’re still full from that? A couple times since I’ve stayed til past dark, and never even made a cast. No bugs, no fish rising, and I didn’t feel like nymphing. Maybe I’ve just had some bad luck with the timing of my outings, but they were all second half of May, when you can usually count on Sulphurs, even if it is an all at once, right at dark deal.
YMMV, but that, coupled with the crowds and the overall setting have had me migrating to some of the other “big” limestoners for my hatch chasing as of late. I’d much rather sit on a log, drink beer, and get my butt kicked by Penns, than by Spring.
I’ll be up for a long weekend the first week in June. I have no plans to fish Spring, unless everything else gets blown out. Even then, I may just fish Brookie streams til dark instead.
