One man has gone missing and another man is dead after separate accidents on Missouri waterways.

The Missouri State Patrol says 33-year-old Jason Hayes of West Alton, Mo was operating a boat on the Missouri River near Pelican Island around 6:40 p.m. Saturday.  His boat apparently struck an unknown object in the water.  The impact caused the motor to become dislodged from the vessel.  Hayes is now reported to be missing.

A boating accident on the Lake of the Ozarks has left a California man dead.  The fatality happened at the Gravois Arm of the lake Saturday afternoon.  Troopers say 52-year-old Raymond Duff of Winnetka, California was guiding a pontoon boat to the shoreline when he exited the vessel voluntarily.  After Duff stepped into the water, he was struck by the wake which resulted in a medical emergency.  Duff was pronounced dead at 2:25 p.m. Saturday at Lake Regional Hospital.

A third accident in Macon County leaves a Columbia man with serious injuries.  Troopers say 55-year-old Robert Benedetti fell while water skiing at the Long Branch Lake around 3:30 p.m. Saturday.  He was first taken to Samaritan Hospital in Macon before being flown to University Hospital in Columbia.
