  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. 7 crests measured on an earlier gauge datum are left out: 3.64 ft on Nov 5, 1957; 8.40 ft on Aug 27, 1959; 8.89 ft on Oct 25, 1971; 9.92 ft on May 5, 1973; 10.60 ft on Jun 25, 1979; 7.87 ft on Apr 28, 1983; and more.
