I've experienced any number of blitzes fishing saltwater but never fresh water before last night. The water was dead calm and I'd just put my boat in the lake and was trolling a spreader with small shad plastics while heading to my favorite spot when pockets of boiling water started all around me. I got my trolling rig out of the water and switched to a small shad lure blade and had a great time catching and releasing 10-12 inch largemouth bass for about half an hour. The phenomenon stopped almost as quickly as it started. Curiously enough I also snagged a fair sized blugill that had joined the party.
