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.
- 31 crests measured on an earlier gauge datum are left out: 16.33 ft on May 27, 1939; 17.30 ft on Jun 4, 1940; 14.05 ft on Sep 15, 1941; 10.40 ft on Jun 19, 1942; 11.35 ft on Jul 20, 1943; 30.50 ft on Jul 7, 1944; and more.
