Upper Mississippi River 9-Foot Project - Locks & Dams
Location/Description
|
The St. Paul District is responsible for maintaining 244 miles of the Upper Mississippi River 9-foot channel navigation system from the head of navigation in Minneapolis to Guttenberg, Iowa. The project is located in or contiguous to Minnesota, Wisconsin and Iowa. The navigation project within the St. Paul District includes 13 sets of locks and dams that are operated and maintained by the Corps. In addition to the locks and dams, the project includes channel maintenance, recreation and natural resource activities.
Annually, approximately 17 million tons of cargo travels through the St. Paul District. The system's infrastructure is comprised of ten 600-foot-long chambers; three 400-foot-long chambers, 13 operable dams, 170 dam gates, 8 fixed-crest spillways and 16 miles of embankments acting as dams. Each lock chamber includes several operable steel gates for hydraulic control during lockages.

Status
|
In 2008, funding is being used to accomplish annually recurring operation and maintenance activities necessary to maintain navigation; continue the endangered species recovery program; and contract maintenance from private industry, including major maintenance construction for Lock and Dam 3 dewatering, stoplog slot cutting at Locks and Dams 5A and 10, and completing the Lock and Dam 10 stage 2 rehabilitation. Slot cutting for stoplogs is required for the safe maintenance dewatering and repair of lock chambers. They are also critical to emergency repairs should the need arise because of a major component failure or barge accident.
Fiscal year 2009 funding will allow completing the stoplog slot cutting at two remaining lock and dam locations. It is also anticipated to allow continuation of Mississippi River endangered species recovery.
|
Authority
|
The project was authorized as part of the River and Harbor Act approved July 3, 1930.
|
Fiscal
|
Operation and maintenance of the project is funded annually under the Corps of Engineers Civil Works Operation and Maintenance appropriation. Mississippi River funding allocated to the St. Paul District in recent fiscal years has averaged approximately $50 million. This amount has been insufficient to sustain preventive maintenance activities and is anticipated to decline as funds are diverted to make critical repairs to the system elsewhere within the region.
