1Mileages are rounded to the nearest 10 miles.

24,300 miles are counted twice as several waterways are state boundaries.

NOTES: The waterway mileages were determined by the following methodology: Length of channels included were those channels (Corps projects and non-projects) with a controlling draft of nine feet or greater, and had commercial cargo traffic reported for CY 98 of CY99, and were not offshore (i.e. channels in coastal areas included only the miles from the entrance channel inward). Channels within major bays are included (e.g. Chesapeake Bay, San Francisco Bay, Puget Sound, Long Island Sound, major sounds and straits in southeastern Alaska). Channels in the Great Lakes are not included , but waterways connecting lakes and the St. Lawrence Seaway inside the U.S. are included.
