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.
Categories use today's flood stages. Levees, dams and channel changes since a crest can make old and new stages not directly comparable.
25 crests measured on an earlier gauge datum are left out: 47.00 ft on May 31, 1929; 51.50 ft on Dec 9, 1935; 43.60 ft on Nov 13, 1961; 43.50 ft on Mar 20, 1972; 41.06 ft on Jun 13, 1973; 26.74 ft on Jun 5, 1981; and more.
