The Eau Galle River is a tributary of the Chippewa River in western Wisconsin in the United States. It is about 35 mi (56 km) long.[1] Via the Chippewa River, it is part of the Mississippi River watershed.
The Eau Galle River was named la Rivière au Galet, "river of the gravely/pebbly banks", by French explorers in the late 17th or early 18th century.[2] Over time the spelling of galet changed to galle, thus causing a 1905 mistake in attribution by Henry Gannett, author of a book on place names in the US, who assumed that the river's name meant "bitter water" in French.[3] There is a persistence of the galet pronunciation in spite of the spelling change to galle.
