In mid-July 1951, heavy rains led to a lot of water in the Kansas River. Flooding happened in the Kansas, Neosho, Marais Des Cygnes, and Verdigris river basins. There was more than $935 million in damage in eastern Kansas and Missouri in June and July 1951. Adjusting for inflation, it would be nearly $8.52 billion in 2016. The flood killed 17 people. It caused 518,000 people to move somewhere else.
