Last time I was down there, about a week ago, I went in at the 28th St ramp, had to break my way in, water temp was in the low 40s. I caught a few walleyes on jigs in the deep pools, and found a few small (12") smallmouth bass hovering near sunken barges. They inhaled small Senkos.
Be very careful launching and watch for shore ice and floating icebergs

....take a bag of cat litter for the ramp and dress warm.
Also, look under "Boat Safety" for my tip concerning a safety line.
