The mighty Missouri again invaded Niobrara in April of 1952 and much of the town and the surrounding area was flooded. This record flow came shortly before the completion of the Missouri River dams, citizens were relieved that flooding along the Missouri would be a thing of the past and life could continue at a more or less routine pace.A big event of the 1950’s was the Centennial Celebration of June 16 – 17, 1956. There were many events leading up to the two day celebration which was attended by an estimated 20,000 people. Later, in the 1950’s and in the 1960’s, it became apparent that the mighty Missouri would, again, influence Niobrara history. Silt from the Niobrara River, which began to accumulate in the river bed, raised the ground water level in Niobrara and the surrounding area. Many basements became flooded requiring constant pumping and it was apparent that the problem would continue to intensify. By 1969, community officials began to look for solutions and a second move.

Funds were appropriated by Congress to pay a sizable portion of the cost of the move. Site preparation began in September of 1973 and was completed in April of 1974. Next came the water, sewer, storm sewer, paving, water wells and water storage tank. The sale of residential lots followed  in the summer of 1974 and residential construction moved forward at a fast pace. By the end of 1977, the move was nearly completed. The 1980 census showed 420 and 213 homes in Niobrara. 1981 marked the 112th anniversary of the original settlement and was celebrated with a historical pageant, parade and other activitiesThrough volunteer efforts, a nine-hole grass greens golf course was completed on the old town site. The Niobrara State Park was relocated, suffering the same fate as the old town. Niobrara’s history can best be summarized as being destined by the mighty Missouri on whose banks it was founded and from whose reach it has continuously tried to escape.
