Little Mud Lake

Little Mud Lake (petit lac Mud) is a lake in South Bruce Peninsula, Bruce County in southwestern Ontario, Canada. It is part of the Great Lakes Basin, and is about 5.5 km northwest of the community of Wiarton.

The lake has one unnamed inflow at the northwest. The primary outflow is an unnamed creek at the southeast which flows to Big Mud Lake and then to Berford Lake, the source of the Rankin River, which in turn flows via the Sauble River to Lake Huron.
