Dredging the Mississippi River 9-foot navigation channel is a critical component to ensure the movement of commercial goods. To maintain the channel, the St. Paul District removes around 1 million cubic yards of dredged material, or river sand, every year. This is enough material to fill US Bank Stadium.
Maintaining the navigation channel is vital to the regional economy. A safe, reliable navigation system allows agricultural producers to save nearly $1 per bushel by shipping corn and soybeans via the Mississippi River navigation rather than other transportations methods.
