The inland waterways of the United States include over 25,000 miles of navigable waters. Much of the commercially important waterways of the United States consist of the Mississippi River System the Mississippi River and connecting waterways. Almost all of the navigable rivers and canals in the United States are in the eastern half of the country. The Columbia, Sacramento, and San Joaquin Rivers are the only major navigable rivers on the West Coast. The steep grades and variable flows of most other West Coast rivers make them unsuitable for navigation. Also, most large rivers there are dammed, often in multiple places, to supply water for hydroelectricity production and other uses. A shortage of water and mountainous terrain in the West make canals unfeasible as well. The U.S. Army Corps of Engineers is responsible for 12,000 miles of the waterways. This figure includes the Intracoastal Waterway. Most of the commercially important inland waterways are maintained by the USACE, including 11,000 miles of fuel taxed waterways.
