The East Branch of the Au Gres River flows through Iosco County — a small, quiet stream access point rather than a lake destination. There's a single launch site here with a 4.3 Google rating, though only three reviews suggest it sees light traffic. The Au Gres River system drains into Saginaw Bay on Lake Huron, running through lowland forests and wetlands typical of this part of northeastern Lower Michigan. Don't confuse this with the nearby Au Sable River — the Au Gres is a separate, smaller watershed. This is the kind of put-in that paddlers and small-boat anglers use to access river stretches rather than open water.
