  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. 55 crests measured on an earlier gauge datum are left out: 10.67 ft on May 15, 1951; 4.41 ft on Aug 21, 1952; 5.39 ft on Aug 20, 1953; 7.67 ft on Aug 7, 1954; 8.08 ft on May 20, 1955; 7.40 ft on Aug 20, 1956; and more.
