Green, Snoqualimie Salmon

Does anybody know anything about Chum fishing on the Green and Snoqualimie Rivers? They're both open, and I've caught silvers out of both of them, so I want to give em a shot. Also, anybody know anthing about sea-run cutts in the tribuaties of the Snoqualimie (Raging, Tolt)? Any info would be appriciated.
