  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: 42.00 ft on Apr 19, 1927; 40.80 ft on May 15, 1943; 40.40 ft on Apr 21, 1945.
