I've used buzz bombs on the lower Snohomish and Skagit for pinks and silvers, but I think the water level in the Nisqually at this time of the year may be too low. All of my strikes on a buzz bomb usually come while the lure tumbles down through the water column when you drop the rod tip. I guess the only way to find out is to experiment. Just make sure you're using a single hook to be legal.
