Two children were flown to Des Moines hospitals in separate near-drowning incidents over the weekend at state park beaches. One from Rock Creek State Park in Jasper County. Alex Murphy, spokesperson for the Iowa Department of Natural Resources, says swimming at a state park beach can be dangerous, as the floor of the lake can drop off suddenly.

Two other incidents on Iowa waterways claimed lives over the weekend. On Friday, a Minnesota man drowned in the Des Moines River while trying to save his 7-year-old niece. It happened below Red Rock Dam in Marion County. The girl was rescued by a boater and transported to a hospital. In Wapello County, a fisherman disappeared Saturday morning on the Des Moines River in Ottumwa. His boat was found, unoccupied, later in the day. The body of 79-year-old Richard Mart, of Ottumwa, was recovered from the river Monday morning.
