  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. 31 crests measured on an earlier gauge datum are left out: 15.00 ft on Aug 3, 1939; 19.80 ft on Jun 4, 1940; 19.00 ft on Sep 15, 1941; 13.70 ft on Jun 30, 1942; 18.00 ft on Jul 19, 1943; 19.70 ft on Jul 8, 1944; and more.
