Salma-
Great info. I was not really promoting it just reporting my experiences back then. I also have been on the Snohomish system since about 1960 so I have many memories to.
You are probably right that all that seeding and extra work did not do much, it was great fishing back then and it all seemed to crash around the same time as Salmo said, the ocean conditions went bad and that had more to do with it than anything.
That Summer Run fishing on the Skykomish back then was world class, it did look like Reiter was the answer, at least for those of us that were hooking 10 of them a day!
Oh, and the seeding, you may not like it, but it made us feel good!!!
