  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. 4 crests measured on an earlier gauge datum are left out: 15.00 ft on Feb 4, 1907; 15.90 ft on Dec 25, 1907; 17.40 ft on Nov 23, 1909; 14.40 ft on Jan 12, 1912.
