There's many more 'Iowa dams' in lurk

The recent collapse of an earthen dam in Iowa seems quite unusual to many people, I think.

And it shouldn't.

There's earthen dams all around the country that have outlived their expected lifespans. Can anybody say Johnstown Flood?

The thing is, it's going to cost money to repair these dams, money that local, county and state governments have in short supply right now.

This is yet another issue of America not paying enough attention to the state of repair, or disrepair, of its own infrastructure.
