Crests at or above flood stage, by decade

  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. 4 crests measured on an earlier gauge datum are left out: 14.00 ft on May 13, 1914; 14.00 ft on May 12, 1943; 14.20 ft on Apr 21, 1945; 14.30 ft on May 18, 1945.
