I was one of the Fishcops assigned to the Cedar and elswhere in the early 70's. Interesting period for that river. If I remember right about four hundred thousand returned/predicted. I caught a couple sockeye trolling the Renton end with an ultra slow flatfish How the lake has changed! I have not kept up with the biology of the big lake, but how can baby sockeye living in the lake that is now full of smallmouth and a healthy cutthroat population survive? Reviving the once prolific sockeye run seems nearly impossible with the "new" habitat compared to fifty years ago. Am I haywire on my un-educated assumption? Sounds like an urban fishing paradise for smallies and cutties.
