The 1913 Dayton flood was the greatest natural disaster in Ohio history. 17 billion cubic feet of water rushed through downtown Dayton in 48 hours on March 23, just after Easter weekend. Over 800 people found shelter, food and welcome from the Marianists at St. Mary’s College, the school that later became University of Dayton. This collection of photographs, postcards, a student-run magazine, original footage and an oral history highlights events during and after the flood — and St. Mary’s significant role in providing relief.
