Dredging operations on the Mississippi River set records during the 2022-23 season, maintaining the congressionally mandated nine-foot-deep, 300-foot-wide navigation channel and coping with the challenges of widespread drought and prolonged extreme low water in the Mississippi River basin.
Dredging operations moved nine million cubic yards of material, at 70 different locations along 300 miles of the St. Louis District. In total, seven dredging units worked throughout the St. Louis District area of responsibility. Two other units, for a total of nine, supported Mississippi Valley Division efforts on the Mississippi River. Normally, an average year results in three to four million cubic yards of material being moved in the St. Louis District by two dredges.
