river in Saginaw Bay Fishing Reports - Walleye Posted January 14, 2012 fished last weekend in the sag river, out of bay city. the current was not bad but the visability was about 2 feet, we did not have a solid hook up in four hours of fishing. we jigged almost to the mouth from vets, the ice was thin then but we still had to break it up, there were 3 other boats that we saw and they were having the same luck! since then the ice has melted temporarily untill last night! any way just thought it might help, soon it should be locked up? for the winter? good luck stay safe!
