never ice fished there but it's great open water, there's big browns and rainbows and good shot of hooking a lunker largemouth (guess largies up to 6-7 lbs aren't all so uncommon out of there)
caught a few rainbows there earlier this year in the 13-15 inch range, a friend of mine hooked a nice +/- 18" rainbow that cartwheeled out of the water and spit his hook out there this year
good luck if you go let me know how it is, i was thinking about trying it
