The Winnibigoshish Lake Dam is a dam at the outlet of Lake Winnibigoshish into the Mississippi River in Minnesota, United States. The dam crosses the county line between Cass County and Itasca County, and lies within the Leech Lake Indian Reservation. The first dam on the site was built by the United States Army Corps of Engineers from 1881 to 1884 to regulate the flow of water on the Upper Mississippi River. A constant flow was desired by loggers, fur traders, and millers downstream at St. Anthony Falls. The current structure was built in 1899. Lake Winnibigoshish is Minnesota's fifth largest lake, at 67,000 acres (270 km2).
