  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. 18 crests measured on an earlier gauge datum are left out: 29.19 ft on Jun 25, 1953; 26.83 ft on Jun 21, 1954; 26.19 ft on Jul 10, 1955; 27.10 ft on Aug 18, 1956; 26.43 ft on Jun 25, 1957; 27.28 ft on Jul 2, 1958; and more.
