Most inland trout streams close September 30 in Michigan. The PM, Manistee and AuSable are open year round with differing regs re keeping trout, salmon, et. al. with numbers and sizes. The guides at Gates on the AuSable are good. Sam Surre is excellent for the AuSable and Manistee watersheds. Glen Blackwood and his shop in Rockford are outstanding (Great Lakes Fly Fishing Company - Great Lakes Fly Fishing Co.
). It is a beautiful time of the year to fish in Michigan.
