The water was more than six feet higher than the 1957 mark when floodwater destroyed the gauge.
The flooding took out bridges and knocked houses off their foundations. It had claimed at least 35 lives as of Monday afternoon.

NPR’s Rebecca Hersher explains that climate change is making extreme floods more frequent. A warming atmosphere can hold more moisture, which means, when it rains, it rains harder.
