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.
- 41 crests measured on an earlier gauge datum are left out: 13.10 ft on Jan 5, 1946; 10.90 ft on Jun 5, 1947; 11.35 ft on Jun 30, 1947; 11.48 ft on Feb 28, 1948; 9.86 ft on Feb 24, 1949; 8.74 ft on Mar 4, 1949; and more.
