2018 Map of Oulu

About this map

The Bois Brule River snakes northward toward Lake Superior, defining the topography of this Northern Wisconsin landscape along the Douglas and Bayfield line. This 2018 survey details a rural region shaped by its hydrology, featuring numerous river landmarks such as Shale Falls, Weir Riffle, and the Highland Thirteen Rapids. These features indicate the river's significant drop in elevation as it approaches the Great Lake, creating a distinct corridor of ledges and riffles that contrast with the surrounding wetlands.
