Now, if ice was let loose gradually, it's not a proble 'cause the river would just take it...

Now, if ice was let loose gradually, it's not a proble 'cause the river would just take it downstream. [narrator] But this was no normal ice flow. It was a freak weather event in which high winds and normal winter ice combined upstream from the bridge to create the perfect storm. Ice was breaking up
on Lake Erie, wind was blowing
out of southwest, so ice that would normally have come down slowly was pushed over the falls. It had so much ice that
it filled up the entire
channel of the river
