  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. 6 crests measured on an earlier gauge datum are left out: 17.96 ft on May 23, 1998; 16.82 ft on May 14, 1999; 19.49 ft on Aug 14, 2000; 15.86 ft on Jul 30, 2001; 16.70 ft on Jul 4, 2002; 17.97 ft on Sep 2, 2003.
