Biron Flowage
United States
Biron Flowage is a 2,187-acre (885 ha) reservoir on the Wisconsin River spanning Wood County and Portage County in central Wisconsin. The modern dam (Biron Dam) was created by the Biron Hydroelectric Company in 1916, it has a maximum depth of 23 ft (7.0 m) and features a sand-gravel-muck substrate, providing a habitat to a number of species of wildlife. The area that includes the reservoir and surrounding wetlands was an ancestral heartland for the Ho-Chunk (Winnebago) people, and was first documented by the French in the early 17th century.
