Abstract : The 9-foot channel project on the Mississippi River from the mouth of the Missouri River upstream to Minneapolis was first authorized in 1930 and provided for a navigation channel having a 9-foot minimum depth and a maximum width of 300 feet. Locks and dams at Alton, Illinois, Winfield, and Clarksville, Missouri are the primary means of providing the minimum depth within the St. Louis District. Maintenance dredging, dikes, and bankline revetments help maintain the 9-foot channel. (Author)
