HAMBURG — Missouri River flooding is flowing over much of the western third of Fremont County and is again threatening Hamburg, Iowa.
Fremont County Emergency Management Director Mike Crecelius said the US Corps of Engineers has informed city officials that the West Ditch No. 6, which protected Hamburg from the flood of 2011, has an elevation of 911 feet above sea level.
Models being produced today show a possible river depth of 917 feet, about six feet higher than the West Ditch.
Crecelius said Hesco bags have been set up in Hamburg and filled with sand. If water gets over the West Ditch, Crecelius said it is hoped that the four-feet Hesco barrier will keep the flood out of Hamburg.
The Hamburg mayor has already ordered the evacuation of every resident from E Street south.
The mayor of Thurman ordered an evacuation there early Sunday morning.
Spotters notified emergency management at 2 a.m. that there was a sudden increase in water flowing near Interstate 29. By 3 a.m., water was overtopping the railroad tracks at McPaul.
Crecelius said spotters told him the water was spreading rapidly, covering a quarter mile every 10 minutes.
Crecelius said the good news is that the Nishnabotna River is going down.
Crecelius: “The Missouri River is running rampant over the western third of the county right now. It has overtopped and blown out — we have one for sure we have laid eyes on — we suspect a couple other spots out there where we have breaches.”
