This project maintains depths of 30 feet in the approach channel, 28 feet in the entrance channel, 27 feet in a major portion of the south basin, 21 feet in the north basin. The project also provides for river channels with a depth of 27 feet in the Kinnickinnic and Milwaukee Rivers, lakeward of the first railway bridges on each river, a depth of 21 feet on the Menomonee River to 25th Street, the South Menomonee Canal to 13th Street, and Burnham Canal to 11th Street. Over 21,000 feet of structures are maintained through this project, including breakwaters, piers and revetments. The Milwaukee Confined Disposal Facility (CDF) is located within the harbor in the southwest corner. A new Dredged Material Disposal Facility was completed in 2012 on top of the old CDF.
USACE is currently designing for upcoming breakwater repairs which include repairing portions of the existing concrete caisson and placement of stone.
