  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: 6.71 ft on Oct 2, 2010; 19.80 ft on Oct 6, 2012; 15.13 ft on Oct 28, 2013.
