So many rivers have sea runs but if you want to slay them wait until the end of July and head to the Cowlitz. There are so many of them and it keeps going right through November. Reagrding salt water Stonefish is right. He and I fly fish for them but the other methods he's mentioned will work if you're not into fly fishing. All sea runs caught in Puget Sound have to be realeased and fished with single barbless hooks. You can keep them in the Cowlitz and the vast majority of them are hatchery fish. You can even use bait there.
