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.
- 9 crests measured on an earlier gauge datum are left out: 30.50 ft on Nov 25, 1909; 30.30 ft on Jan 8, 1923; 24.70 ft on Feb 23, 1927; 30.60 ft on Jan 2, 1943; 28.35 ft on Dec 30, 1945; 27.47 ft on Jan 9, 1948; and more.
