  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. 12 crests measured on an earlier gauge datum are left out: 16.65 ft on Jul 2, 1983; 19.82 ft on Aug 4, 1984; 17.86 ft on Jul 2, 1985; 16.21 ft on Sep 5, 1986; 16.60 ft on Jun 1, 1987; 16.24 ft on Aug 5, 1988; and more.
