The Dust Bowl made the Great Depression much worse. Thousands of families left for the West Coast. Dust Bowl occurred in 1930. It is one of the worst droughts ever to hit North America. There were four waves of droughts, with each happening right after another. The droughts occurred in 1930-1931, 1934, 1936, and 1939-1940.
The Dust Bowl caused many to abandon their farms because they had lost all they had, and they couldn’t grow crops. The Dust Bowl hit the Oklahoma panhandle the most. Deflation during the Great Depression along with the drought reduced cotton yields from six bales an acre to two parcels an acre during the same period. It cost farmers more to plant cotton than they could get selling it.
