MISSOURI VALLEY, Iowa (AP) – Residents of a neighborhood in Missouri Valley have been evacuated after water from the overflowing Boyer River broke through a levee. About 70 residents in the southeast corner of the city were asked to leave their homes after the levee breach occurred at around 7 a.m. Monday two miles east of Missouri Valley near U.S. Highway 30.

Residents on four streets have been evacuated as of noon. Mayor Clint Sargent says a shelter was set up in the city of 2,700 but no one has made use of it with most people staying with relatives or friends.

Sargent says it’s unclear how long the evacuation will be needed but the river was receding.
