  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. 25 crests measured on an earlier gauge datum are left out: 38.00 ft on Sep 1, 1900; 27.00 ft on Jun 21, 1926; 26.42 ft on May 21, 1928; 33.90 ft on Jun 15, 1930; 35.09 ft on Sep 10, 1932; 32.07 ft on May 20, 1935; and more.
