Eau Claire River (Chippewa River tributary)

Its name is the French translation from the Ojibwe Wayaa-gonaatigweyaa-ziibi (Clear potable-water River).

The Eau Claire River rises as two streams, the North Fork Eau Claire River and the South Fork Eau Claire River, both of which rise in southwestern Taylor County and flow generally southwestwardly through northeastern Clark and northwestern Eau Claire Counties.

The North Fork is about 25 mi (40 km) long and flows past the village of Lublin; it collects the Wolf River in Eau Claire County.

From the convergence of its headwaters' forks, the Eau Claire River flows generally westwardly through northern Eau Claire County for about 40 mi (64 km), past the city of Altoona to its confluence with the Chippewa River in downtown Eau Claire.

Eau Claire River (named the "Clear Water River, a branch of the Chippewa") serves in part as the boundary between the Chippewa and Winnebago in an 1825 treaty,[2] and as a southern boundary for the 1837 Treaty-ceded Territory, where the signatory Ojibwe Bands may hunt, fish and gather to maintain their cultural livelihood.
