  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. 29 crests measured on an earlier gauge datum are left out: 45.00 ft on Dec 26, 1951; 39.40 ft on Feb 26, 1957; 43.30 ft on Dec 21, 1957; 42.20 ft on Feb 16, 1958; 42.60 ft on Jan 12, 1959; 41.00 ft on Nov 10, 1960; and more.
