  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. 15 crests measured on an earlier gauge datum are left out: 14.70 ft on Jun 5, 1903; 13.70 ft on Apr 6, 1912; 14.00 ft on May 8, 1916; 14.30 ft on Apr 10, 1920; 15.40 ft on Apr 24, 1922; 15.50 ft on Mar 23, 1929; and more.
