Addendum

My cousins house in Greeley, Co, did in fact get flooded; they got out with car and clothes on back; I'll have to talk to them to learn if they have anything to go back to.  And the south end of my North Platte is indeed threatened by the coming water.     North Platte still treats it's sewage in old-fashioned lagoons near the forks of the Platte by the way, and the mother Platte is naturally where both Lincoln and Omaha get a big chunk of our drinking water from.  We'll see how that goes.
