Officials urge recreationalists to stay clear of flood

     LINCOLN, Neb. (AP) - State officials are urging outdoor recreationalists to stay away from flood waters in western and central Nebraska.  The warning came after Nebraska Game and Parks officials rescued a man from the South Platte River earlier this week. Authorities say two brothers from Colorado launched a canoe into the swollen river on Wednesday. The canoe capsized about a mile east of the Nebraska-Colorado state line.  Authorities say 48-year-old Joseph Schneiderwind, of Conifer, Colo., remained on a sandbar while his brother, 54-year-old Mike Schneiderwind, swam to shore. Mike Schneiderwind, of Castle Rock, Colo., walked to U.S. Highway 138 and flagged a motorist for help.  Authorities say Joseph Schneiderwind was chest-deep in water and clinging to a tree when they arrived. He was taken to a hospital to be treated for possible hypothermia.
