(Radio Iowa) – Residents in Sioux City’s Riverside neighborhood have been advised to prepare to evacuate due to major flooding. The Tyson Events Center is open for those who need a place to shelter. The Missouri River crested this (Monday) morning in Sioux City. John Benson, the director of Iowa Homeland Security and Emergency Management, says a lot of water is headed downstream. “This flood is not over,” Benson says. “…If you go look at the river gauges in the Missouri (River), they are going up and they are going to go up quickly. You will see those gauges peaking beginning the back part of this week.”

Most of the docks at the Missouri River Boat Club in Sioux City have been destroyed. The Big Sioux River meets the Missouri River in the area and Fleet Captain Dennis Butler says a massive amount of debris has been swept down the Big Sioux, including entire trees. Butler estimates it will take at least a couple of weeks to repair the docks. “Even with (the river) going down, we’ve got a lot of dock repairs to do, salvage what we can here and just hope to God it didn’t take everything away,” Butler says. “Got to get a little break to let us try and rebuild.”

On the South Dakota side of the Sioux City metro, a railroad bridge over the Big Sioux River collapsed at 11 o’clock Sunday night. The bridge was primarily used by trains hauling grain and crushed rock from Sioux City to Sioux Falls, South Dakota.
