This flooding carried over from April when several periods of heavy rain in eastern Nebraska and southwest Iowa combined with snow melt and rain upstream to produce a prolonged period of high water along the Missouri River, mainly downstream of Plattsmouth. Although most of the flooding was confined to marshy areas and farmland along the river, a few roads and recreational areas were also flooded. However, the flooding got much worse in June.
