Riverdale is an unincorporated community in western Christian County in southern Missouri, United States.

This was followed by numerous others, leading to the construction of a three-story mill building in the early 1890s.

In the early 1900s, the current dam was constructed and an iron truss bridge crossed the waterway.

The mill burned in 1926 and was not rebuilt, ending the era of flour production.
