What flood stages mean, across every listed crest

Flood stage is set per gauge by the National Weather Service: minor means little or no property damage, moderate means some buildings and road closures, and major means extensive flooding. Of 238,551 listed crests, 146,667 reached flood stage and 16,608 reached major.

Crests at each stage

Listings favour bigger floods, so the shares do not describe an ordinary year.
