Dwight D. Eisenhower Lock

The Saint Lawrence Seaway Development Corporation (www.seaway.dot.gov) celebrated its 50th anniversary in 2009. The Great Lakes - St. Lawrence Seaway System (GLSLS) was constructed as a commercial shipping channel from the Great Lakes to the Atlantic Ocean and back.

The Eisenhower Lock is a United States-operated lock in a series along the St. Lawrence River. There are two SLSDC-operated locks in Massena, New York: Eisenhower Lock and Snell Lock. They are both gravity-fed and are located on the Wiley-Dondero Canal, which is about 8 nautical miles long. The System System is managed in partnership by both the U.S. and Canada.
