The southern-most lock on the Lower Fox River System. This lock represents the first "step-down" towards the eventual river level entering Green Bay.

It was first opened for navigation in 1856, then rebuilt in 1970 with reinforced concrete. Major gate repairs were completed in 2014. The lock is 144 feet long by 35 feet wide.

The lock was closed on September 3, 2015 due to finding the round goby, an invasive species, below the Neenah Dam.
