160000 At this approximate discharge, the Corps will raise the gates out of the water, creating "open river" conditions.
28.6 Water enters the elevated flood building north of the lock house.
28 In Monkey Run, at least a dozen homes are flooded at this level.
27.8 Saverton homes begin flooding near this level.
27.3 The work shop building at Lock and Dam #22 begins flooding at this height.
27 Sny Island Cell #1 levee is overtopped
26 In Monkey Run (north of Saverton), houses begin flooding near this level.
25.7 Water enters Lock house north door and the railroad tracks crossing.
25.5 Homes in Riverview Acres (just south of the lock and dam) begin to flood. Also, North Saverton Road floods near this height.
25.2 Missouri Route E becomes impassable and is closed from Saverton Road near the Hascall Creek bridge to Lock and Dam 22.
24.5 Highway 79 is closed at the Continental Cement Plant.
24.2 Missouri Route E begins flooding at the lowest points.
21.8 At this height, the ties of the BNSF railroad tracks begin flooding.
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.
15.5 An access road to riverside raised homes on the riverward side of the Sny levee begins to flood near this level.
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.
