A 400' aerial view overlooking the Sacramento Deep Water Ship Channel, a canal that runs from the Port of Sacramento in West Sacramento, California, to the Sacramento River, which flows into San Francisco Bay. It was completed by the United States Army Corps of Engineers in 1963. The channel is about 30 feet deep, 200 feet wide, and 43 miles long.

It was authorized by the River and Harbor Act of 24 July 1946.  Construction started in 1949, though it was stopped in 1950 and did not start again till 1956, with ship operation not until June 1963.  The channel is part of the California Green Trade Corridor project, as ships move cargo much greener than trucks and trains.  The Port of Sacramento is a significant port on the West Coast of the United States, but receives far less traffic than larger ports. It handles primarily agricultural products and other bulk goods rather than containers, which dominate the shipping market.
