All that water from the Mississippi River is headed down river right through the city of Newport. Flood waters are just a foot below the top of the city’s earthen levee. It was built after devastating flooding in 1965. Officials will tour the levee on Wednesday. City officials said they hope to be able to buyout the impacted homeowners and turn that area into a riverside park.

The city of Carver is also dealing with an outdated levee. Volunteers from across the Twin Cities metro helped to fill sandbags at Lions Park Wednesday in hopes of holding back the Minnesota River. City leaders said it would cost more than $15 million to build a new levee, and some historic buildings would have to be removed.
