145000 This is the flow at which CAGM7 will go to "open river" conditions.
37.1 This is the level at which the Winfield levee failed in June 2008.
37 Water reaches the top of the lock wall. Also at this level water completely floods Lock and Dam Park in Winfield. Highway 79 is closed a half mile south of Highway 47 for another half mile.

34.6 Route M is closed south of Elsberry from Highway 79 east to where state maintenance ends near Apex Lane.
34 This is the level of the levee protection for Winfield.
33.5 Near this height, the office building and storage building of Kimaterials, a sand and gravel company on Highway 79 between Winfield and Old Monroe, begins flooding. Also, the Corps has not kept Lock 25 open above this height.
32.9 Route N is closed from Highway 79 at Winfield to where state maintenance ends.
30 The Golden Eagle Ferry will likely close near this level. Lakeshore Drive in northern St. Charles County becomes impassable near this level.

24 Water begins covering Highway C about a half mile south of Highway B in St. Charles County.
23 A few local islands begin to flood.
21.6 Near this stage, the Corps will raise all gates out of the river, creating "open river" conditions. This corresponds to an approximate discharge of 145,000 cfs.
