  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. 13 crests measured on an earlier gauge datum are left out: 7.38 ft on Jul 3, 1906; 7.83 ft on Jul 3, 1907; 7.09 ft on Jun 12, 1921; 7.05 ft on Jun 5, 1922; 8.92 ft on Dec 11, 1937; 7.09 ft on Dec 23, 1964; and more.
