I want to rescind my Nestucca guess------- I'm not Oreo contingent.....but just threw it out. In fact I couldn't even find it on the map!!!

However,, I didn't read your clues until today..
So it might be the S. Fork Santiam, but you live in Kingston, probably not...

How about the N. Fork Skokomish before Cushman????? Don't know when the dam was built,,,,,But that is my final answer and I'm sticking to it (since someone already guessed Sultan)

Plus, I don't even want the 'crummy' spoon!!!
