<<always prepared.
The Elkhorn River is a football-field's length away from my back door. Between the house and the river is my backyard; nothing there excepting the flora and the occasional fauna.
Because of my "life style," the irreplaceables--the family stuff dating back to the 1720s, the china, the linen, the silver, the photographs, the letters, the diaries, the coronation stuff, &c., &c., &c.--is kept in a secured storage place in town; none of my "valuables" are out here. There's some stuff in the safe deposit box at the bank, and my financial and legal stuff is in a safe 120 miles west of here.
Basically all that's here is thrift-store furniture.
So if worse came to worst, all I'd have to do is grab the cats and head out.
The question I can't seem to get an answer--perhaps in real life I ask it in a confusing way, I dunno--is this:
The Elkhorn River flows unimpeded into the Missouri River.
If a dam on the Missouri River up in South Dakota burst, that would of course overload the Missouri River south of it. In fact, it could very well wipe out some towns on the Nebraska side.
(I'm miles and miles and miles away from the Missouri River itself.)
With all this water racing down the Missouri River from South Dakota, what happens with the water in the Elkhorn River also trying to merge with the Missouri? Does it back up, or what?
