Navigation Study

In 1999, the Army Corps of Engineers began a study to determine the feasibility of expanding the Seaway to accommodate movement of larger shipping vessels through the Seaway.

The expansion of the Seaway would mean the destruction of miles of fragile habitat, re-suspension of polluted sediments and exacerbate the introduction of invasive species into the Great Lakes and St. Lawrence River.

In 2007, the Army Corps of Engineers gave their most recent report on this issue. The report did not focus on the physical expansion of the Seaway, a victory for the River and Great Lakes. However, the report fell short of formally removing expansion options from further study.

Save The River continues to monitor the status of the Seaway studies to be sure that no further proposals for expansion of Seaway infrastructure are brought forward.
