  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. 5 crests measured on an earlier gauge datum are left out: 14.30 ft on Mar 19, 1929; 15.60 ft on Apr 5, 1948; 12.36 ft on Sep 26, 1953; 7.99 ft on Jan 1, 1954; 7.11 ft on Sep 14, 1955.
