Yeah, there's nothing wrong with the Snoqualmie. You just don't want to fish Tokul. Big Eddy is worth throwing a float rig in for a few minutes. There are also some other good places to fish down by Fall City and the mouth of the Raging. Likewise you can fish down by the mouth of the Tolt. Me, I've never had much success on the Snoqualmie, but it's got a few small stretches of good water and some folks are quite successful.
Also, I'm not really a trout fisherman, but I hear there are some great spots above the falls.
