Sturgeon Bay, Wisconsin -- Project Description and Background
Serves as a deep draft commercial ship canal with 8.5 miles of federal channel. Authorized project depths of 22 to 23 feet in the entrance channel and canal; 20 feet in the turning basin at Sturgeon Bay.
Over 15,100 feet of timber crib structures with concrete caps and wood pile structures with concrete caps and armored with rubble mound breakwaters and revetments. Over 8.5 miles of maintained channel.
Maintenance dredging of approximately 80,000 cubic yards is required on a 5-year cycle. In 2021, 60,000 cubic yards of sediment were removed from the channel at State Highway 42 to the entrance of the Sturgeon Bay Ship Canal. The dredged material was placed at the privately-owned Sturgeon Bay disposal site.
Current Status
Funds will be used for operation and maintenance of existing structures including repair of 1,394 linear feet of breakwater at Reaches A through D which intercept the most severe wind/wave conditions and protects the channel from north to south littoral sediment movement. Award of the construction contract is scheduled for late summer 2023.
