In United States law, Littoral rights are rights concerning properties that abut static water like an ocean, bay, delta, sea or lake, rather than a flowing river or stream (riparian). Littoral rights are usually concerned with the use and enjoyment of the shore., but also may include rights to use the water similar to riparian rights.
An owner whose property abuts tidal waters (i.e. oceanfront) owns the land to the mean low water line or 100 rods below mean high water, whichever is less. The land between low water and high water is reserved for the use of the public by state law and is regulated by the state.
