Notes: 

The waterway mileages were determined by the following methodology: Length of channels included were those channels (Corps projects and nonprojects) with a controlling draft of 9 feet or greater, and had commercial cargo traffic reported for CY98 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 United States are included.

Description: 

1 Mileages are rounded to the nearest 10 miles.

2 States do not add to total due to waterways on state boundaries.
