  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. 2 crests measured on an earlier gauge datum are left out: 59.88 ft on Feb 27, 1932; 59.93 ft on Nov 13, 1932.
