  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. 34 crests measured on an earlier gauge datum are left out: 1.95 ft on May 31, 1947; 1.75 ft on Jun 14, 1948; 3.44 ft on Jun 21, 1949; 2.01 ft on Jun 18, 1950; 2.19 ft on Sep 4, 1951; 1.69 ft on Jun 20, 1952; and more.
