The Locks / Rapide Croche

Rapide Croche (A French term which means “fast hook” or “fast bend”) is currently a sealed lock that acts as a barrier to prevent Great Lakes Aquatic Invasive Species from traveling further up river to the Lake Winnebago system.

The Fox River Navigational System Authority is committed to maintaining an effective barrier for all aquatic invasive species, yet allowing navigation of the lower Fox River through the lock system. We are seeking other, more effective ways of both opening navigation and preventing invasive species from getting into the system. An electric barrier similar to the one proposed for the Menasha lock is also under consideration for this Lock.
