  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. 22 crests measured on an earlier gauge datum are left out: 5.50 ft on May 25, 1946; 14.35 ft on Mar 22, 1947; 13.10 ft on Mar 14, 1948; 7.48 ft on Mar 23, 1949; 15.40 ft on Apr 15, 1950; 6.34 ft on Mar 25, 1951; and more.
