Man drowns as boat falls over Linn Grove dam
Robert Wiese, 61, of Greenville, was attempting to launch a boat on the Little Sioux River at Linn Grove on Saturday when his boat went over the dam, taking Wiese with it.
Witnesses said they saw Wiese go over the dam and disappear underneath the water about 25 yards below the dam at 2:26 p.m. Rescue operations were started at that time. At 4:25 p.m. during the search, the body was found a half-mile downriver.
