The term submerged lands is used here to refer to tidal waters lying between the high water mark and the seaward extent of the state’s jurisdictional limit, which for most states is three nautical miles (i.e., the Submerged Lands Act Boundary). See the Submerged Lands definitions page for specific terminology used in each state.
