In the 90's, I watched a guy catch a spring chinook in the Satsop on eggs. It was June 1.

In Salmo. G's defense he was only 2 holes up from the mouth, so it could have easily been a wrong turn at the mouth.

Later in life I actually ended up sort of befriending the guy who caught the springer that day. I asked him about it (this was 3 years later) and he actually caught 7 of them that week. A feat he never repeated or had done before that.
