The frequency of dredging is decided by the U.S. Army Corps of Engineers. It depends upon several factors: how nearby streams/rivers behave, weather patterns, construction nearby, or how much agricultural activity is in the area. Dredging occurs so that commercial vessels may pass through the waterways without scraping their boats on the bottom. It is difficult to say how often a waterway needs to be dredged since the above conditions are constantly changing, but the link below explains everything about dredging the Great Lakes, including environmental impacts and sludge use.
