  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. 20 crests measured on an earlier gauge datum are left out: 5.86 ft on Jun 19, 1992; 5.62 ft on Jul 27, 1993; 4.78 ft on Apr 27, 1994; 6.89 ft on Jun 8, 1995; 5.97 ft on Jun 2, 1996; 11.13 ft on Jun 14, 1997; and more.
