From March 23, 1913 to March 27, 1913, the entire state of Ohio was under water, enduring what is still considered the worst weather-related incident to ever hit the Buckeye State.

467 Ohioans died and more than 40,000 homes were flooded as 6 to 11 inches of rain fell, pushing rivers and dams past their brinks. Here are photos, as well as artistic postcards, detailing the episode.
