As far as I'm aware the salmon on Mary Ronan have been less than cooperative this year...and as far as Hauser goes, I'm not aware of Kokes still in there...the Walleye got em all...Unless you've been made aware of new info.
I use to fish Hauser 25 years ago and catch 2-3lb Kokes on a regular basis...they were all nice size and some big ones every now and then. But then they introduced Walleye into Canyon Ferry and they made it over the spill way and pretty much devistated the Kokes in Hauser...FWP also stopped stocking Hauser with Kokes. So not sure where you got your info but it may be suspect.
