Don't forget that you can only keep sockeye up to Gilligan creek on the south Skagit hwy. Not sure where you are staying .
Water looks pretty good but above Gilligan creek it restricted to artificials only , no bait , no smelly jelly. single barbless hook with no more than a 1/2" gap.
Good luck , hopefully you can hookup a catch and release king headed for the marblemount hatchery
