North Branch of Ausable Question

Hey guys I had a question as far as winter/early spring goes on the north branch. I taught myself to fly fish about 12 years ago and I really only have had luck from May-September but then again I haven't really fished the river too hard outside of those months. I know the main is the place to be this time of year and fall but I don't have any buddies that fly fish so I usually fish alone. I have been hesitant to wade bigger unfamiliar waters by myself. I've fished the Manistee around Frederick but I am most familiar with the north branch and have really only fished dries. Anybody catching fish in the winter/early spring months on the north branch?
