  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. 9 crests measured on an earlier gauge datum are left out: 27.60 ft on Mar 14, 1922; 25.30 ft on Mar 12, 1923; 24.60 ft on Dec 13, 1923; 23.60 ft on Mar 19, 1925; 28.10 ft on Sep 5, 1926; 27.20 ft on Apr 1, 1927; and more.
