Comments: On June 8, 1953, the Floyd River again flooded when a torrential downpour in the Sheldon, Iowa area sent a wall of water down into the lower valley. Fourteen people lost their lives. This flood was a major impetus for the Floyd River flood control project, including the building of a straightened, rock-lined channel and high levee through the city. (source: Wikipedia)
