  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. 20 crests measured on an earlier gauge datum are left out: 4.17 ft on Jul 13, 1962; 5.28 ft on Jun 9, 1964; 4.80 ft on May 20, 1965; 5.22 ft on May 7, 1966; 5.44 ft on Jun 6, 1968; 5.06 ft on Apr 23, 1969; and more.
