SIOUX CITY---Siouxlanders are preparing for the worst flooding along the Missouri River in nearly 60 years.
The Army Corps of Engineers plans to relieve pressure on reservoirs swollen by heavy rains and winter storm melt from Montana and the Dakotas.
The Missouri River is forecast to crest about five feet above flood stage in Sioux City, where Mayor Mike Hobart says they're working closely with their colleagues across the river.
In Dakota Dunes, many of the town's 2,500 residents are preparing for evacuations. In Sioux City, Chris Larson Park, the Anderson Dance Pavilion and a nearby Flight 232 Memorial have already been closed.
Mayor Hobart expects other facilities will be shut down as the waters rise over the next week to 10 days.
Hobart also expects a few businesses will be flooded in the South Bridgeport Industrial Area and flooded basements in downtown Sioux City.
Volunteers will gather outside the Longlines Family Center, from 6 to 9 tonight, for a "Sand Bag Jam." Organizers have set a goal of making 15,000 sandbags.
