The Dredge Potter crew finished up an unprecedented 2022-23 season on February 1, 2023, that required tremendous teamwork to maintain the congressionally mandated nine-foot-deep, 300-foot-wide navigation channel and overcome the challenges from the widespread drought, and prolonged extreme low water that affected 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 -- dustpan, cutterhead and mechanical -- were working 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.
