Southeastern Nebraska is a fairly hilly place and the original surveyors probably chose a spot in a relatively low lying area because they could get a good line of sight. Enough rain, increased farming activity, and suddenly the creek is now 100 yards over from where it had been. Once you have a benchmark you can't very well move it on a whim.
