Well, I was there once in March, twice in April and once in May. No springers for me, but saw quite a few caught. I fished the Barrier Dam area. I think that there are way more salmon than last year... However, in 2006, I used to catch them left and right in April and May. On spoons! This year might be just as good regarding their numbers (I don't believe the official predictions), or even better. Locals catch their share every day, I saw that.
I was there last Sunday, saw springers jumping particulary in the boat launch area and below. Water was low, my eggs were not the first-class... So I went and nailed a chrome steelhead on spoon.
Going on weekend? Good luck - it is crowded.
