Every listed crest
102 crests from 1957 to 2025. Filled: at or above flood stage. Hover a crest for its date and stage.
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.
21 crests measured on an earlier gauge datum are left out: 20.13 ft on Oct 2, 1959; 18.00 ft on Jun 12, 1960; 19.00 ft on Nov 2, 1961; 19.60 ft on Jun 24, 1963; 19.00 ft on Nov 17, 1964; 18.70 ft on Sep 21, 1965; and more.
