I'm not so sure about Twanoh State Park, but definitely Belfair State Park....Was there over the weekend at my parents beach house...Huge schools of Chum and Coho jumping everywhere...I was using smallest green corky I could find with tad of green yard...Hook 4 in about 3 hours legitimately and snagged over a dozen...Only got one coho on a Hootchie Blue Fox combo...Have to work hard for those buggers...I believe it is call Mission Creek...It's on the left facing out of the park towards the water...Good Luck...Also no people there, they are all at Hoodsport...
