I got to know, as this was the title of a fishing show seminar, which turned out to be on the Kasilof River:
"Alaska Steelhead On The Cheap With Daily Double Digit Hookups"
And by this title, the speaker means these are the current fishing conditions, as in the last few seasons in the fall period of Sept-Oct (not in the 1990s, when it was hatchery-enhanced to 10X current levels). The talk had glorious shots of large steelhead and fancy lodging, and a show special price as well ($3,500/wk).
Well - my internet searching reveals an average recent run of ~500 fish which is a good natural run but not the thousands of the past. And steelhead can be a challenging fish - well - you can get into good days, but 10-20 hookups on average, every day? Seriously?
So who has some experience on this river that can shed some light on this topic.
