  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. 5 crests measured on an earlier gauge datum are left out: 7.97 ft on Mar 15, 1947; 9.58 ft on Jun 4, 1953; 7.96 ft on Jun 12, 1958; 13.50 ft on Jun 9, 1964; 9.19 ft on Jun 19, 1975.
