Crests at or above flood stage, by decade
- 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.
- 8 crests measured on an earlier gauge datum are left out: 1,245.00 ft on Apr 10, 1969; 1,237.70 ft on Sep 23, 1986; 1,234.85 ft on Jul 4, 1992; 1,240.55 ft on May 8, 1993; 1,233.30 ft on Jun 14, 1994; 1,237.90 ft on Mar 28, 1997; and more.
