LANSING — Everybody knows water flows, but not many people know that the sediment below it does too. That’s why harbors need dredging, or excavating the gradually accumulated material on the bottom and transporting it elsewhere. U.S. Army Corps of Engineers Detroit District planned eight dredging projects in Michigan and Wisconsin for 2014 at a cost of $13.2 million. But Congress recently allocated an additional $17.8 million. That allows the district to include eight new projects and increase funding for four of the original projects.
