I drove out to Macbride and the upper end of Coralville res. this noon to check ice/water conditions.
The ice is 99% out on Coralville from the flood plain down to Mehaffy Bridge. There were about a dozen boats up above the interstate and 965 bridges; tomorrow morning mine will be out there, too. I have not heard anything about the channel cat bite there, but my limited experience is that they start hitting on the flood plain as soon as the ice is gone.
For once, a prediction I made (on this forum) turned out to be completely right: Macbride is still 95% covered with ice, but it looks very rotten and should be gone next weekend. The boat ramps are all locked up, but there is a good-sized patch of open water on the east side of the causeway.
Finding the Coralville flood plain completely open is good news, since Macbride isn’t open yet and the Mississippi is pretty much un-fishable, by all accounts.
