  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: 30.90 ft on Mar 29, 1899; 31.00 ft on Jun 8, 1906; 32.70 ft on Apr 12, 1907; 31.90 ft on Sep 8, 1911; 33.00 ft on Apr 5, 1912; 30.10 ft on Mar 24, 1916; and more.
