Full Definition Of Live Thalweg

The live thalweg is the part of a river channel that is most followed, typically found in the middle of the main channel. It is used to define the boundary between states, serving as a line that follows the lowest part of a valley or the middle of the primary navigable channel of a waterway. For instance, in the Louisiana v. Mississippi case, the Supreme Court established the live thalweg as the part of the river channel that is most followed by the water. This means that the boundary between the two states is determined by the middle of the primary navigable channel of the river. This example demonstrates how the live thalweg is utilised to settle disputes between states, such as determining ownership of an island in the Mississippi River. By following the most navigable part of the river channel, the court was able to determine which state had jurisdiction over the island.
