Willow Creek is a neighborhood in the city of Portage, Indiana in Porter County.

[2][3] It is the location of the junction of the Garrett Subdivision, Porter Subdivision, and Barr Subdivision, all sections of the CSX Railroad.

[citation needed] Willow Creek is the site of the Willow Creek Confrontation.

According to a marker placed by the Indiana Historical Bureau, this occurred when the Michigan Central Railroad refused to allow a Baltimore and Ohio Railroad line to cross its tracks.

The Michigan Central briefly defied court orders and the state militia, but eventually a crossing was built at Willow Creek Station.
