The Iowa Department of Natural Resources (DNR) says one man was seriously injured in a boating accident on the Missouri River in Harrison County on Sunday evening. Shortly before 8 p.m. near the Little Sioux Boat Ramp, 23-year-old Nathan Case of Omaha, Neb. was thrown from the front of an open bow boat after hitting a wake caused by another vessel. The boat he was a passenger on traveled over the top of Case and he was hit by the propeller. Case was airlifted to Creighton University Medical Center in Omaha, Neb. He was not wearing a life jacket and the boat’s operator, 32-year-old Brett Feder of Omaha, Neb., was charged with failure to have a throwable flotation device on board and for having an expired boat trailer registration. The incident was investigated by authorities from the Iowa DNR and the Nebraska Game and Parks Commission.
