NORTH SIOUX CITY, S.D. (AP) — An official with the U.S. Army Corps of Engineers says a study is needed to consider changes to flood-control measures along the Missouri River south of Sioux City, Iowa. Speaking after a U.S. Senate field hearing Wednesday in North Sioux City, South Dakota, Brig. Gen. Peter Helmlinger noted such a study could call for actions such as changing the Missouri River channel in the Sioux City area to let the river spread out and carry more water.

The Sioux City Journal reports that levees also could be rebuilt farther from the river to give the waterway more room. Helmlinger, commander of the corps’ Northwestern Division, says such a study would take three years and be delivered to Congress. He spoke after answering questions at a hearing headed by Sen. Mike Rounds of South Dakota.

Officials say no injuries were reported following a house fire early this morning, in Shelby. According to a social media post by Minden Fire and Rescue, their crews were dispatched at around 4:30-a.m., to assist the Shelby and Avoca Fire and Rescue Departments. No other details are currently available.

The Creston Police Department reports 68-year old Rosalie Jackson, of Creston, was arrested at the Creston Wal-Mart, Wednesday afternoon. She was taken into custody on a 5th Degree Theft charge, cited and released from the scene, on a Promise to Appear in court.

CLIVE, Iowa (AP) — Officials in suburban Des Moines are seeking answers on what has caused a creek there to turn bright green. The Des Moines Register reports that city officials reached out to the Iowa Department of Natural Resources on Tuesday morning after a Clive resident posted a photo online of a vivid green Walnut Creek.

Department officials have since taken samples of the water, but Clive Assistant City Manager Pete DeKock says the department has not shared the results with city officials. DNR senior environmental specialist Janet Gastineau says the agency has traced the green water back to a lake in the Country Club development, but did not say caused the bright green color.
