Not in recent times but not sure about way back. Lots of things went on last century and example is 5 million Fall Chinook eggs transferred from old Schafer Park hatchery to upper Chehalis Hatchery and they perished when the hatchery had a problem. So this, normal timed Coho, Chum, and Fall Chinook have had stocks moved all over and it is the smaller runs like Springers and Late Coho that remained untouched. The Bingham Late Coho are not the same as the native late Coho that used to be mostly late Dec and Jan returning fish. You just about have to be an historian to track this stuff.
