  1. 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.
  2. Categories use today's flood stages. Levees, dams and channel changes since a crest can make old and new stages not directly comparable.
  3. 26 crests measured on an earlier gauge datum are left out: 22.50 ft on Jun 13, 1877; 23.70 ft on May 4, 1881; 24.50 ft on Jun 24, 1883; 22.20 ft on Jun 16, 1885; 29.50 ft on Jun 7, 1903; 24.60 ft on Jun 8, 1929; and more.
