  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. 18 crests measured on an earlier gauge datum are left out: 29.80 ft on Jun 1, 1889; 26.40 ft on Mar 24, 1898; 23.70 ft on Mar 1, 1902; 24.20 ft on Mar 4, 1904; 24.20 ft on Nov 4, 1904; 26.80 ft on Feb 21, 1918; and more.
