The Portage Canal was built to connect the Fox River and Wisconsin River at Portage, Wisconsin along the Fox-Wisconsin Waterway.

Fort Winnebago was a 19th-century fortification of the United States Army located on a hill overlooking the eastern end of the portage between the Fox and Wisconsin Rivers east of present-day Portage, Wisconsin. It was the middle one of three fortifications along the Fox-Wisconsin Waterway that also included Fort Howard in Green Bay, Wisconsin and Fort Crawford in Prairie du Chien, Wisconsin. Fort Winnebago was constructed in 1828 as part of an effort to maintain peace between white settlers and the region's Native American tribes following the Winnebago War of 1827. The fort's location was chosen not only because of its proximity to the site of Red Bird's surrender in the Winnebago War, but also because of the strategic importance of the portage on the Fox-Wisconsin Waterway, a heavily traveled connection between the Great Lakes and the Mississippi River. Fort Winnebago's location near the portage allowed it to regulate transportation between the lakes and the Mississippi. With the exception of the participation of troops from the fort in the 1832 Black Hawk War, Fort Winnebago was not involved in any combat operations during its occupation by the U.S. Army. Instead, the garrison, which from 1829 to 1831 included Lt. Jefferson Davis (later President of the Confederate States of America), was put to work in building a military road between Portage and Fond du Lac, Wisconsin, and assisting with the relocation of the Ho-Chunk Nation from Wisconsin to Minnesota during the 1840s. In 1845, the absence of any real threat to peace in the region prompted the abandonment of the fort. Nine years later the site was sold into private hands, and in 1856 a fire destroyed much of the fort.

The Leopold Wetland Management District is named after Aldo Leopold, who is widely acknowledged as the father of wildlife conservation in America. Leopold is perhaps best known as the author of A Sand County Almanac, a book compiled of essays written on his farm in central Wisconsin. In tribute to his philosophy, the Leopold Wetland Management District is dedicated to preserving, restoring, and enhancing wildlife habitat in Wisconsin for the benefit of present and future generations. The district, established in 1993, manages over 12,000 acres (49 km2) of waterfowl production areas (WPAs) in 17 southeastern Wisconsin counties, covering some of the most important waterfowl areas of Wisconsin. The district also administers 45 conservation easements, totaling 3,000 acres (12 km2), in 34 eastern Wisconsin counties. WPAs consist of wetland habitat surrounded by grassland and woodland communities. While WPAs are managed primarily for ducks and geese, they also provide habitat for a variety of other wildlife species such as non-game grassland birds, shorebirds, wading birds, minks, muskrats, wild turkeys, and deer.
