  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. 2 crests measured on an earlier gauge datum are left out: 17.55 ft on Oct 11, 1953; 16.78 ft on Oct 24, 1956.
