Welcome!

The Great Lakes Dredging Team is a partnership of federal and state agencies created to assure that the dredging of U.S. harbors and channels throughout the Great Lakes, Connecting Channels and tributaries is conducted in a timely and cost effective manner while meeting environmental protection, restoration, and enhancement goals.

The Great Lakes, as the largest system of freshwater in the world, are a valuable and unique resource. The use of these waters for recreational and commercial navigation requires the continued maintenance of harbors, ports, marinas and shipping channels throughout the Great Lakes. Dredging is required to construct navigation channels and to maintain depths for safe navigation at existing ports and harbors. Dredging is also required to construct and maintain other important facilities, such as water supply intakes, bridges and utility crossings and for the remediation of contaminated sediments.
