  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. 19 crests measured on an earlier gauge datum are left out: 11.00 ft on Aug 12, 1905; 8.17 ft on Jul 29, 1951; 6.75 ft on Jun 5, 1952; 4.19 ft on Mar 13, 1953; 11.98 ft on May 23, 1954; 9.68 ft on Aug 12, 1955; and more.
