  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. 3 crests measured on an earlier gauge datum are left out: 12.30 ft on Sep 6, 1909; 10.20 ft on Jun 29, 1927; -9.90 ft on Aug 11, 1929.
