MI - Lake Michigan beaches getting replenished through harbor dredging

The U.S. Army Corps of Engineers is using harbor dredge material to shore up Lake Michigan beaches this summer.

DETROIT — The U.S. Army Corps of Engineers is using harbor dredge material to shore up Lake Michigan beaches this summer.

Four harbors along Lake Michigan — Holland, Grand Haven, St. Joseph and South Haven — were approved for dredging this spring and summer. Materials gathered through the process will be used to “nourish and replenish” beaches that suffered erosion from recent high water levels.

Dredging is the removal of sediments and debris from the bottom of bodies of water.

“Nourishing beaches using shoaled sand into these harbors rather than trucking in new material is very functional and cost effective,” stated Grand Haven Resident Engineer Elizabeth Newell Wilkinson. “It allows for both dredging and beach nourishment.”

The Corps of Engineers sampled dredged material to determine if it would be “suitable for beneficial reuse” as nourishment material. The Michigan Department of Environment, Great Lakes and Energy issued certifications for the projects following the sampling.
