I was out in the boat on the Kankakee yesterday with my boy. All the backwaters are wide open. White Oak Bayou was maybe 20% ice covered, but I sure wouldn't trust that ice.
There were quite a few other boats at the ramp, too, and a couple people fishing from the bank. We didn't do worth a bent nickel, but it was nice to be back in the boat.
I don't use any open water sites. Used to peruse a couple FB groups for local rivers, but it was a drama fest, so I dropped out of them several years ago.
