Re: Cali trip
If I could add just a bit re Putah...it's a brushy little sucker, so you'll need to bushwhack a little bit. Plenty fishable, but certainly not just walk up and start making long false casts. It IS a good choice for you...
The fish are coming off the redds now, but the redds will be ripe with eggs for another month roughly. Try to avoid wading in the shallower, gravel bottom areas.
Regs are barbless, no take.
It's a unique and sweet stream, fun to fish. And MP is absolutely right about tiny bugs.
