Rock Island District Illinois Waterway and Upper Mississippi River  


The Dredged Material Management Program (DMMP) evaluates and identifies preferred alternative dredged material placement site(s) using a six-step planning process and, where applicable, a matrix with six evaluation criteria: dredging cost; natural resources; beneficial use of dredged material; recreational resources; cultural resources; and social impacts.  


The Rock Island District has been developing plans and acquiring and implementing sites for the long term placement of channel maintenance dredged material since the completion of GREAT II (Great River Environmental Action Team) studies in the early 1980s.


The Rock Island District is preparing long-term (20-40 year capacity) Dredged Material Management Plans (DMMP) and acquiring and implementing sites for the placement of channel maintenance dredged material in support of the operation and maintenance of the Upper Mississippi and Illinois Waterway nine-foot navigation channels. The program ensures that all practicable and reasonable alternatives for the placement of dredged material are fully considered on an equal basis. This includes the placement of dredged material in the least costly manner, at the most practicable location, and consistent with engineering and environmental requirements.
