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.
- 8 crests measured on an earlier gauge datum are left out: 21.00 ft on Jan 13, 1901; 18.00 ft on Dec 4, 1902; 22.00 ft on Jan 25, 1903; 21.50 ft on Nov 23, 1909; 18.20 ft on Feb 7, 1916; 18.00 ft on Jan 7, 1923; and more.
