Army Corps of Engineers removes enough sediment each year to fill a stadium (approximately 250,000 cubic yards). Sediment naturally flows downstream with the current, and when it does it clogs things up. This commerce supports more than 17,000 jobs, all of which depend on the shipping channel remaining clear. But now there’s a controversial new proposal on the table to dump the dredged material into Lake Erie, a source of drinking water for more than 11 million people.Įvery year nearly 13 million tons of iron ore, limestone, cement, and salt are hauled into the Port of Cleveland and unloaded. The standard practice has been to put the river muck in confined disposal facilities ( CDFs). The Cuyahoga River in northeast Ohio - known for catching fire in the 1960s - relies on frequent dredging. When dredged material is contaminated, it raises questions about how to dispose of it safely. In the Great Lakes states, 60 commercial ports rely on this practice. Every year nearly 13 million tons of iron ore, limestone, cement, and salt come through the Port of Cleveland. In order to maintain open navigation channels for ships, sediment buildup in waterways has to be scooped out periodically through a process known as dredging.
