What is the boundary mark at which littoral rights end?

Littoral rights refer to the rights of landowners whose property is adjacent to a body of water, such as a lake or an ocean. These rights typically include access to the water and the use of the shoreline. The boundary where these rights end is established by the Mean High Water Mark.

The Mean High Water Mark is defined as the average high tide line over a specific period, which marks the boundary between private property and public water. Landowners have rights to the land up to this line, while the area beyond that falls under public domain and is subject to state rules and regulations concerning water usage.

Understanding where littoral rights end is crucial for property owners, as it delineates what they can legally use and maintain. This concept is important in real estate transactions and property development along waterfronts. The other options represent varying aspects of water levels but do not delineate where littoral rights conclude as definitively as the Mean High Water Mark does.
