Late Ice Protocol
All things being equal, the ice on both Saginaw Bay (and all pts. North) and out in the Irish Hills should be in great shape all weekend long. Depending on where you would like to go, it might get dicey after this upcoming Wednesday. Warm weather seems to be coming.
Dicey means leaving the machines at home, and treating your trips onto the lakes like first ice conditions. With late ice though, even more caution is needed. What can look like good ice, can in fact be rotten underneath. Pack light, take the essentials, unpack the spuds and spikes and try to fish with a partner when possible.
Mom used to have a saying back in my early driving days, you can be right, and you can still be dead. Course she was referring to following the rules of the road, but always use caution, you never know what the other drivers are going to be doing. Same holds true with ice fishing (and lots of other outdoor activities), you can do everything right and you still might end up dead.
Instead of looking out for other drivers though, be aware of the ice conditions around you. What is the wind doing? Where did all those other anglers go all of a sudden? Why am I the only one still fishing? All these can be tell tale signs of something changing in the conditions of the ice. The latter two, are specially true when you are fishing on bodies of water not totally familiar to you. Consider how rapidly things can change on big bodies of water compared to inland lakes, and make your decisions accordingly.
Late ice can be some of the best fishing of the season. Walleye, pike, crappie and bluegills will begin staging for their spring rituals. All will be looking for food where they can find it in anticipation of the spring spawn, and the action can be fantastic. You will enjoy every bit of it, just be aware of the conditions and take the right steps to enjoy it for many years to come.
good luck
