I've only bream fished there once, and it was 30 years ago. Me and a buddy stopped in Airpark/State Park area of the Upper Blue Basin, rented a john boat (I had an electric trolling motor and battery) and just went along the grassy banks there in mid-April dunking crickets 2 feet under a bobber tight to the grass. Caught 50 or 60 big bream in a couple hours. Pretty sure all of them were bluegill, but there may have been a shellcracker or two in the mix.
