The U.S. Army Corps of Engineers operates and maintains the Upper Mississippi River 9-Foot Channel Navigation Project, and one method used to maintain the 9-foot channel is dredging river soils or “material.” The purpose of the Pool 9 Dredged Material Management Plan is to prepare a coordinated long-term plan for managing dredged material in Pool 9. This plan was initiated due to needs for dredged material management at upland placement sites, especially in the upstream reach of the pool.

Silver Jackets teams are collaborative, state-led, interagency teams that are continuously working together to reduce flood risk at the state level. Through the Silver Jackets program, the U.S. Army Corps of Engineers, the Federal Emergency Management Agency, and additional federal, state, and sometimes local and tribal agencies provide a unified approach to addressing a state’s flood risk priorities. Often, no single agency has the complete solution, but each may have one or more pieces to contribute. Silver Jackets team activities and projects occur throughout Wisconsin.

Bighead and silver carp were introduced to the Mississippi River in the 1970s after wastewater treatment ponds were overcome from flooding on the lower Mississippi River. Left uncontrolled, the invasive carp’s feeding habits starve other species and cause turbidity in the waters where they feed, detrimentally altering the habitat that supports native species. Left unchecked, it is concern that the invasive species will continue to expand further upstream into the upper Mississippi and Ohio Rivers. The purpose of this project is to monitor and limit the spread of invasive carp species.

This embankment rehabilitation project addresses restoring embankments to meet current design standards. Overtopping protection adjacent to concrete structures is the priority for design and construction efforts; no increase in the height of the embankments is planned.

A draft Problem Appraisal Report completed in 2017 found that complete riprap overlay of the embankments to rehabilitate rock degradation was not economically justified but that there are other opportunities to improve scour resilience while improving the ecosystem. Some options include creating upstream berms, creating islands to reduce wave fetch, and providing submergible segments with crest superiority at some dams.

The tow rail system is integral to the operation of Mississippi River Locks and Dams 2 through 10. At each lock, a tow rail system is attached to the top of the lock guidewall to help guide tows through the lock chamber. The tow rail systems of Locks and Dams 2 through 10 have been deteriorating over the past several years, requiring rehabilitation of these systems.

Locks and Dams 3 through 10 have auxiliary chambers. Each auxiliary chamber has only a single set of miter gates that could pass shallow draft navigation traffic if the lock chamber was out of operation and the upstream and downstream pools were equalized. At each site, the U.S. Army Corps of Engineers only installed one set of miter gates. An auxiliary lock chamber was never authorized by Congress, which would have included a second set of miter gates. Since installation, the auxiliary emergency gates have never been used, and the gate operating machinery was never installed.

Maintenance of dam spillway gates are required to avoid degradation and eventual replacement. Cost analyses show it is economically favorable to maintain these gates rather than replace them. There are also reliability and safety concerns with allowing the gates to degrade to the point that they must be replaced.

The sedimentation of backwater areas of the Upper Mississippi River is an ongoing issue. The project area is greatly influenced by the input of sand from the Chippewa River, entering Pool 4 at approximately river mile 764. Other potential sources of sand are the historic channel maintenance dredging side-cast islands and the four active temporary placement sites within the study area. Big Lake has lost much of its island complex and bottomland forest to wind and wave erosion. The barrier islands between the lake and Catfish Slough have been degraded and/or eliminated over the past several years.
