Littoral rights are determined by the fact that an owner's land abuts what type of water body?

Littoral rights pertain to the rights of landowners whose property borders navigable waters, such as lakes or tidal bodies of water. These rights generally include the use and enjoyment of the water adjacent to their property, allowing them to access, use, and develop the shoreline. Littoral rights are crucial because they acknowledge the natural and economic value of these water bodies, providing a broader context for land use laws and property rights.

Navigable waters are defined as those which can be used for commerce or transportation, and this classification plays a significant role in determining property rights. In contrast, non-navigable lakes, coastal estuaries, and intermittent streams do not grant the same level of rights, as they don't typically provide the same level of public access or commercial usage that navigable lakes or tidal waters do. Thus, the focus on navigable waters in the context of littoral rights affirms the necessity of maintaining access for personal use and public enjoyment, distinguished from the limitations associated with the other types of water bodies mentioned in the options.
