Be careful on those. Two years ago we had a little run-in with river ice while duck hunting. We did an afternoon hunt and when we on our way back to the ramp we ran into a giant sheet of ice. It had broken off somewhere up north and was blocking the ramp. It was a good 200 yards long and 100 yards wide and 8-10″ thick. One guy in another boat that was also stuck actually got out of his boat and walked across the ice to the ramp. He got his trailer and drove up to the next ramp up river, and we followed them. Then they gave my buddy a ride back to the other ramp to get his truck.
What I’m getting at, is that even though it is safe ice.. it could break off of shore at any time and send you down river . I’ll never fish river ice again after seeing that, just backwaters for me!
