It’s not just the Missouri River people in North Sioux City are worried about, but also an incredibly full Big Sioux River.

As thawing temperatures continue to change the river level models, water is coming in higher and faster than predicted Saturday.

The Big Sioux River water levels have risen to almost 32 feet and are projected to reach over 35 feet by Sunday afternoon.

A temporary ring levee has been built to 40 feet- still 5 feet higher than the crest. 

However, should the models change, an action plan is in place.

Ted cherry, North Sioux City administrator says, “If we see the river levels coming up to a stage of 37 feet we would add more height to the temporary levee that we currently have. So, at this time the city of North Sioux is protected from the rising waters and there are action steps in place to continue to monitor the river levels and provide for additional protection if needed.”
