The central feature of this navigation system is 29 locks and dams on the Upper Mississippi River that help maintain a permanent 9-foot channel for barge traffic (Figure ).

These were originally constructed in the early s to reduce the amount of dredging required to maintain the 41⁄2 foot navigation channel.

Improving fish passage through dams is recognized as an important way to restore river ecosystems. The Upper Mississippi River System (UMRS) has a series of 29 navigation dams on the Mississippi. Nearly fish were released below Lock and Dam 2 (LD2) in the Upper Mississippi River and tracked to determine both whether and how they passed through this structure, and if passage could be.

With the enactment of new authority The study area contains over 2, wing dams, closing structures, and. Water Quality and Fish Data from the Upper Mississippi River Restoration Environmental Management Program population and the associated degradation of aquatic resources (Naiman and Bilby ).
ily through construction of numerous wing dikes and more closing dams. of the century, wing dams and closing dams were constructed to divert water away from off-channel habitats and constrict the flow to the main navigation channel. This was supplemented with dredging and snag removal to maintain first a m and then a m minimum depth.

Upper Mississippi River into a reliable transportation route. To achieve the 4 1/2-foot channel, the Corps narrowed the river’s main stem with wing dams and employed dams to cut off its side channels. Placed in a series along one or both sides of the river, the wing dams reduced the channel width at low flows.
River channelization structures (e.g., wing and closing dams) were constructed prior to lock and dam construction as the primary means of maintaining navigable depths throughout the system.
Downstream of St. Louis, there are no dams and the navigation channel of the Mississippi River continues to be maintained with channelization structures.
