The Republican River Flood of 1935

The spring of nineteen thirty-five had already been one of the hardest on record across southwest Nebraska and northwest Kansas. The drought was in its fourth year. Topsoil that had blown away in nineteen thirty-three and thirty-four had left the land raw. Then, on the night of May thirtieth and the morning of May thirty-first, a series of severe thunderstorms dumped extraordinary amounts of rain across the Republican River watershed in eastern Colorado and southwest Nebraska.

The Republican River runs southeast out of Nebraska and across northwest Kansas before joining the Smoky Hill River. On that Friday morning, its watershed filled faster than it ever had in recorded history. The river crested at levels that overwhelmed every bridge and ford and community in its path.

The flood killed approximately one hundred thirteen people in Nebraska and Kansas, though the records from the most remote stretches of the valley were incomplete, and some accounts cite numbers somewhat higher or lower. Entire farm families were swept away during the pre-dawn hours when the water came without warning. Communities along the river, including Benkelman, Culbertson, and Republican City in Nebraska and Concordia in Kansas, suffered severe destruction.

The flood arrived in the middle of the Dust Bowl, which meant that the communities it struck had already been weakened by years of failed crops and foreclosures. The same Republican River Valley that had been turning to dust in dry weather was now under water, and the two disasters, drought and flood, do not cancel each other out. They compounded.

The Republican River Compact, signed by Colorado, Kansas, and Nebraska at the end of nineteen forty-two and approved by Congress in nineteen forty-three, was one of the direct legal consequences of the flood. It divided the river's water among the three states and established the framework for management that still governs the basin today.
