The Great Flood of 1913: Indianapolis

The 1913 flooding affected Indianapolis, Fort Wayne, Lafayette, Terre Haute and most locations along White River, the East Fork of the White, Wabash and Whitewater rivers. Rainfall for the five-day period beginning March 23 ranged from 2 inches in Northwest Indiana to more than 11 inches in the Richmond/east-central Indiana area.

The AZO stamp box dates this RPPC as being anywhere from 1904 to 1918. More info and a short video about the disaster is available here:
