Crests at or above flood stage, by decade
- These are the crests the local National Weather Service office lists for the gauge: the highest on record and recent crests. Lesser floods between them may be missing, so counts by decade are a floor.
- Categories use today's flood stages. Levees, dams and channel changes since a crest can make old and new stages not directly comparable.
