Rapide Croche ("Eighth Rapids") is a complex comprised of a dam, a hydro-electric powerhouse and a lock to navigate around the dam. The lock is permanently closed, it was sealed in 1988. As of this writing, the lock is not available for viewing. It is closed and de-watered, acting as a barrier to aquatic invasive species (AIS) that could travel from Green Bay into the Lake Winnebago ecosystem.

A future plan calls for a transfer station to replace the lock that will lift watercraft from downriver, subject it to a 110 bath to kill off hitchhiking species, then return the craft to the upriver position.

The lock provided a 9.4' lift. It was built in 1859, rebuilt between 1931 and 1939, and permanently sealed in 1988.

The dam is maintained by the U.S. Army Corps of Engineers, the powerhouse is operated by Kaukauna Utilities, the lock is under the control of the Fox River Navigational System Authority. (Control of the locks passed from the Corps of Engineers to the State of Wisconsin in 2004. The Fox River Navigational Authority was created in 2005.)
