Optimum Timing for Dredging in Great Lakes Harbors Takes a More Scientific Turn

It can’t happen just any old time. Removing sediment from or adding it to harbors to help ships pass or for construction projects is regulated by state and federal rules designed to lessen impacts to the plants and animals living in both marine and fresh water. The Wisconsin and Minnesota Sea Grant programs are working with partners to apply the best science to the timing of dredging windows for Great Lakes harbors.
