Raymond Bailey, Cuming County Surveyor, testified about the direction of the flow of a creek, but his testimony did not establish what may have caused the change in the direction of the flow. Plaintiff claims that a town’s work on a man-made ditch diverted the waters of a creek to flow into another ditch which flooded his pastures. Court held that evidence failed to establish that the activity of the defendants caused the damage to plaintiff’s pastures. Steffen v. County of Cuming, 195 Neb. 442, 238 N.W.2d 890 (1976).
