In addition to the relocation of buildings, the project called for movement of roads, and railroad tracks. Two significant towns, Iroquois and Morrisburg had sections built on higher ground. The flooding officially began on what became known as Inundation Day which was scheduled for 1 July 1958. The widening project of the St. Lawrence River, had been planned since 1941 and included cooperation between both the American and Canadian sides of the river. The agreement, signed 19 March 1941, detailed plans for Ontario Hydro and American power companies to significantly increase the power potential by 1.1 million horsepower, each, from the development of an international rapids section of the seaway. This was desired to improve wartime power demands although the construction occurred well after the war ended. This was in part, due to the fact that the United States Congress did not ratify these plans due to more immediate concerns posed by the Pearl Harbor Attack and other interests. The original plans further called to reduce the severity of the rapids at Long Sault by effectively flooding the rapids. Further, a deep water canal was planned for the American side to permit ocean-going vessels to travel further inland. The plans required the Canadian side of the river to take the brunt of the flooding as the shore line in Ontario was shallower than in New York State.
