Secondary levy being built to protect Iowa town

Temporary repairs have been completed on the breached Missouri River levy threatening Hamburg, Iowa, but officials are now building a secondary levy to help protect the town in the southwest corner of the state.

The Iowa National Guard used a helicopter to drop 22 half-ton sandbags on the breached levy in Missouri's Atchison County. Iowa Homeland Security and Emergency Management spokesman John Benson says the breached levy appears to have been stabilized for the moment.

The U.S. Army Corps of Engineers has begun work on a secondary earthen levy on the south side of Hamburg that is expected to be completed within the next few days.

Benson says the evacuation of the southern half of Hamburg's roughly 1,100 residents should be completed by the end of Monday.
