  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: 6.66 ft on Apr 2, 1950; 7.20 ft on Jun 19, 1964; 6.62 ft on Jun 23, 1967.
