The Buffalo District Corps of Engineers is responsible for dredging the harbors in Lakes Erie and Ontario. Approximately 2,000,000 cubic yards (1,529,000 cubic meters) of material are dredged annually, of which 40 to 50 percent must be placed in confined disposal areas. In Toledo Harbor, open-lake disposal was recently approved with the provision an expanded monitoring program be started. Water quality in the disposal area was monitored during disposal operations. Results shown that the plume was confined in the disposal area and that water quality standards were not violated. Laboratory studies have shown that only a small percentage of the phosphorus contained in Toledo Harbor sediments becomes biologically available.
