Navigability also depends on context: a small river may be navigable by smaller craft such as a motorboat or a kayak, but unnavigable by a larger freighter or cruise ship. Shallow rivers may be made navigable by the installation of locks that regulate flow and increase upstream water level, or by dredging that deepens parts of the stream bed.
The Columbia River is the only river on the West Coast (and arguably the entire North American Pacific coast) that is navigable for a significant length. The river is regularly dredged, and freight barges may reach as far inland as Lewiston, Idaho, through a system of locks; however, there are strict draft restrictions beyond the confluence ...
Total length of waterways per country in kilometers. This is a list of waterways, defined as navigable rivers, canals, estuaries, lakes, or firths.In practice, and depending on the language, the term "waterway" covers maritime or inland transport routes, as suggested by "way".
The Wabash River between Terre Haute and the Ohio River was navigable by large ships during much of the 19th century, and was a regular stop for steamships. By the late 19th century, erosion due to farming and runoff made the Wabash impassable to such ships.
Still unresolved at this point is the sticky question of how to define which rivers and streams in Georgia are navigable and, thus, open to fishing, and which are off limits. ...

Waterways have been an important part of human activity since prehistoric times and navigability has allowed watercraft and canals to pass through every body of water.The Grand Canal (China), a UNESCO World Heritage Site, the oldest known waterway system in the world, is considered to be one of the world's largest and most extensive project of engineering.
The river's length is 130 miles, its drainage basin is 7,340 sq.mi. and the average 30-year discharge at Elizabeth, Pennsylvania, is 9,109 cfs. It falls 3,831 ft. in elevation from its highest source to its mouth on the Ohio River. It falls 280 feet from its forks to its mouth, a stretch made navigable by locks. The mean depth is about 20 ft.
