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.
- 33 crests measured on an earlier gauge datum are left out: 7.56 ft on Jun 2, 1944; 7.60 ft on Jun 24, 1945; 5.95 ft on Jun 5, 1946; 6.33 ft on May 11, 1947; 6.77 ft on Jun 6, 1949; 6.09 ft on Jun 6, 1950; and more.
