Section 1122 of the Water Resources Development Act of 2016 authorizes 10 pilot projects for beneficial use of dredged material.
Section 204 of the Water Resources Development Act of 1992 provides continuing authority to study and implement small aquatic ecosystem restoration projects using dredged material.
Section 217 of the Water Resources Development Act of 1996 authorizes the Corps of Engineers to implement public-private partnerships to manage dredged material.
Dredged material is incorporated into topsoil products that meets Minnesota Department of Transportation specifications for use on highway shoulders where specific drainage requirements are needed.
The St. Paul District is actively seeking landowners willing to accept dredged material or to sell potential placement sites.
Bring dredged material directly to shore instead of using temporary islands whenever possible to reduce life-cycle dredging costs.
The St. Paul District is seeking permission to use non-standard real estate instruments where less than a fee title interest would be sufficient to support the Corps of Engineers needs.
The public, private entities and government agencies are encouraged to take material free of charge from Corps of Engineers dredged material stockpiles.

Dredged Material Management Plan

The U.S. Army Corps of Engineers, St. Paul District, is currently exploring options to continue its maintenance requirements of the 9-foot navigation channel. This channel includes the Mississippi River, from Minneapolis to the district's southern boundary at Lock and Dam 10, in Guttenberg, Iowa, as well as small portions of the Minnesota, St. Croix and Black rivers. 

Part of the maintenance effort includes finding permanent, suitable locations to place material removed from the channel. Doing so ensures navigation vessels can safely move bulk cargo to ports within the United States and beyond. St. Paul District staff are in the process of looking at a variety of options in various locations along the Mississippi River to place dredged material. The purpose of these dredged material management plans, or DMMPs, is to prepare a coordinated, long-term plan for managing dredged material. 

These plans were initiated because permanent placement sites previously used along the Mississippi River have reached capacity. In addition, existing island transfer sites have a limited capacity. Dredged material placed at island transfer sites will need to be offloaded to permanent sites. Therefore, additional permanent sites are needed to accommodate the Corps’ dredging needs. 

Costs associated with managing the dredged material have increased significantly during the past 20 years, so the plans will also look for ways to reduce the costs to tax payers.

The Lower Pool 4 draft dredged material plan was released for public comment May 11, 2017. The comment period was extended four times before closing Aug. 25, 2017. Corps staff are currently developing a completely new draft plan and hope to have it available for public comment in the spring of 2020.

Corps staff are currently finalizing a draft dredged material management plan for Pool 6 within the Mississippi River. A public meeting was held Jan. 31, to discuss planning efforts within Pool 6. Click here to view the news release.

Corps staff are currently working with our federal, state and local partners to develop a draft dredged material management plan for Pool 9 within the Mississippi River. There is no current timeline for releasing the draft document.


Beneficial use of dredged material

In order to maintain the 9-foot navigation channel, material that settles in the channel area must be removed. Dredging is a method for removing that material. This material is placed in designated areas along the river. Some of these areas are beneficial use placement areas.

Beneficial use of dredged material is the productive use of the material by the public or private sectors. Examples of common beneficial uses of dredged material in the St. Paul District are upland habitat development, wetland creation, aquatic habitat enhancement, creation of areas for bird nesting, beach nourishment, winter road maintenance, levee repair and improvement, aggregate for concrete, bank protection and general purpose fill.

As a result of the Great River Environmental Action Team, or GREAT, study completed in 1980, Blackhawk Park was selected as one of the designated dredge material placement sites in Pool 9. Utilization of Blackhawk Park as a placement site reduced transport distance and subsequently the cost of hydraulic and mechanical dredging, while providing an opportunity to rehabilitate and enhance existing recreational facilities.

The Channel Maintenance Management Plan is a comprehensive, long-term plan for guiding channel maintenance activities in the St. Paul District. The plan evolved from the GREAT study (1974-1980) and subsequent planning efforts to implement GREAT study recommendations. It provides long-term planning, establishes coordination procedures and an evaluation process for dredged material placement site alternatives and provides historic data related to the channel maintenance program. While long-term in nature, the plan is designed to accommodate new information and changes.
