Via the Wisconsin River, it is part of the watershed of the Mississippi River.The Baraboo River was probably named after a French trader in the area, Francois Barbeau, although it may also be a corruption of a French word or phrase.CourseThe Baraboo River rises in southeastern Monroe County and flows generally southeastwardly through Juneau, Sauk and Columbia Counties, past Kendall, Elroy, Union Center, Wonewoc, La Valle, Reedsburg, Rock Springs, North Freedom, West Baraboo and Baraboo. It flows into the Wisconsin River from the west, about 3 mi (5 km) south of Portage.
