Doc, the fact that all of PS drained through the Chehalis is why that mainstem is now viewed by hydrologists as way "undersized". It used to carry a lot more water. Was one of the "ahah" moments to realize just how much things have changed in a short time. And how plastic and invasive salmon are.

We are now seeing the same thing in the High Arctic and Pacific Salmon invade the north slope of Canada. Eventually, will they cross the continent and move into the Atlantic? Will Grey Whales do the same and restore the Atlantic Greys?
