160000 At this approximate discharge, the Corps will raise the gates out of the water, creating "open river" conditions.
28 In Monkey Run, at least a dozen homes are flooded at this level.
27.8 Saverton homes begin flooding near this level.
27 Sny Island Cell #1 levee is overtopped
26 In Monkey Run (north of Saverton), houses begin flooding near this level.
25.5 Homes in Riverview Acres (just south of the lock and dam) begin to flood.
25 Water enters Lock House.
24.2 Missouri Route E begins flooding and is closed from Saverton Road near the Hascall Creek bridge to Lock and Dam 22.
21.4 Near this level, the lock is closed to navigation. This level will vary with circumstance. Also, BNSF railroad tracks just south of Hannibal are flooded.
19.6 The north end of Saverton Road begins to flood.
13.5 This is the upper navigational limit for the pool at Lock & Dam 22.
13.4 This is the target pool for navigation at Lock & Dam 22.
13 This is the lower navigational limit for the pool at Lock & Dam 22.
12 Buildings in unprotected areas are damaged. At this approximate stage, the Corps will lift all gates out of the river, creating "open river" conditions. This takes place at a discharge of around 160,000 cfs.
