There is actually a picture of a sport caught chinook down on the naselle river that was in the low to mid 80's. It must have never been officially weighed as it's not noted as a state record. But it sure looks to be a monster, the pic was from the 30's though...

I know the run no longer exists but the elwah and columbia basin used to get summer run chinook that topped 100 pounds in the late 1800's and early 1900's before the dams.. Of course there are no sport caught records for them though..
