Yup with have some waters that stay open all year. Theres actually a pretty long section of the Au Sable that is open year round because its No Kill C&R that runs through the town of Grayling. But this section that I like to fish is just a little ways downstream from the area thats open year round. This section here is Special regs Fly&artifical only but they close it last day of sept to fishing in that stretch.

All the streams that get Salmon&steelhead runs like Manistee, Rifle, Pere Marquette stay open year round so theres quite a few other options for winter trout. Or as I mentioned just head upstream about 20 miles and the upper Au Sable is open year round.
