  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: 11.24 ft on Jun 23, 1951; 15.25 ft on Jun 9, 1952; 11.13 ft on Jun 4, 1956; 16.40 ft on Jun 9, 1957; 14.18 ft on May 31, 1958; 13.51 ft on May 14, 1962; and more.
