Dredged Material Thalweg Placement Site Mississippi River Miles 301.2 - 301.3 Saverton, Missouri
The area of the Mississippi River upstream from Lock and Dam 22, near Saverton, Missouri, is recognized as a frequent shoaling area. This has resulted in the need for costly and recurrent dredging to keep that portion of the channel open for navigation. Since 1970, this area between River Mile (RM) 301.7-303.4 has required 9 dredging events. Over that time, sedimentation in this area has necessitated the removal of approximately 400,000 cubic yards of dredged material. Adjustments and repairs to training structures (wing dams) have led to dramatic reductions in dredging and emergency concerns. A problem associated with all locations requiring chronic dredging is the availability and suitability of placement sites once the dredged material has been removed from the river. Presently, the material (primarily sand) is hydraulically pumped to any of several historic placement sites. The purpose of this project is to maintain the commercial navigation 9-foot channel in such a manner to avoid potential loss of life or personal injury that may result from channel closures and subsequent groundings.
