Levee Contains NishnaBotna, Roads Swamped In Iowa

HAMBURG – The levee between the NishnaBotna River and Hamburg is holding Wednesday, but rising streams and rivers have prompted a flash flood warning for Fremont County.

Fremont County Emergency Management Director Mike Crecelius says Railroad Avenue near the famous West Ditch between Hamburg and Interstate 29 has been closed.

Highway 333 west of Hamburg has low spots. The Riverton Road is also closed.

The Nishnabotna at Hamburg is over its banks and water is at the base of the levee. The river is expected to crest at 30 feet, posing no threat of topping the levee there.

However, the access area is flooding and the river will top local farm levees at 27.5 feet.

A flood warning is in effect for Otoe, Cass and Johnson counties until 7 p.m. due to river and streams near bankfull. Social media reports indicate numerous roads overtopped by water.

A flash flood warning is also issued for Fremont County in southwest Iowa.

Preparations are being made at the Nebraska City shipping dock for alternative offices as the Missouri River rises above flood stage over the weekend.
