  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. 9 crests measured on an earlier gauge datum are left out: 23.90 ft on Jan 24, 1925; 15.40 ft on Jan 28, 1926; 13.40 ft on Mar 6, 1927; 22.30 ft on Aug 23, 1928; 23.60 ft on Mar 11, 1929; 29.70 ft on Oct 6, 1929; and more.
