I'm not sure, but the ice season might already be done south of I-80 in eastern Iowa for the year.
I fished a pond in northern Johnson County yesterday (Monday) morning. The shoreline ice was firm, no cracking and sagging. Six or seven inches of decent ice farther out. The rain and above-freezing temps (highs in the mid-fifties by afternoon) had already gotten here, but I figured I would be able to come back and fish the same holes yesterday evening.
Nope. This pond, which has a lot of runoff coming in to it, had three or four feet of open water all around it at 4:30 yesterday, thanks to the steady rain and rising water level. I did not have a plank to walk, so no fishing for me. Had I been able to cross the open water, I doubt that I would have still found six inches of ice beyond it.
I looked at several other ponds on my way to and from work in CR today. The ones with less runoff don't look as bad, but every one of them had open water around the edges. It rained pretty hard over night and this morning at times, so the ice still there now took a beating.
Bigger water like Macbride may still have safe ice for walking (I have not checked it), but if I were to try it I would be very careful.
It is cooling off outside now, and of course it is still February, but I doesn't look like southeast Iowa will get enough cold weather to refreeze those small ponds I looked at yesterday and today.
The good news is the ice in northern Iowa or southern MN and Wisconsin should be good for a couple weeks or so yet.
