Submerged Lands Act
The Submerged Lands Act of 1953 is a U.S. federal law that recognized the title of the states to submerged navigable lands within their boundaries at the time they entered the Union. They include navigable waterways, such as rivers, as well as marine waters within the state's boundaries, generally three geographical miles (almost exactly 3 nautical miles or 5.6 kilometres) from the coastline.
