1993 and 2010 brought major flooding to Iowa and Ames was right in the middle of it each time. Both times we saw major flooding in Hilton Coliseum.
In 1993, all 99 counties in Iowa were declared a disaster zone by the governor due to the flooding. Many homes were destroyed, and farmers crops were wiped out. Hilton Coliseum took the hit as well. Water from the Squaw Creek and Skunk River poured over its banks and flooded Ames. At one point, the flood waters were 14 feet above floor level.
It was estimated that Iowa State University took over $7 million in damages from the flood in 1993.
