  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. 7 crests measured on an earlier gauge datum are left out: 14.90 ft on Jul 18, 1915; 14.80 ft on Apr 22, 1920; 15.00 ft on Mar 22, 1927; 14.00 ft on Feb 27, 1929; 13.08 ft on Jan 29, 1952; 13.14 ft on Apr 22, 1972; and more.
