Which term describes the rights related to owning land adjacent to a lake?

The correct term that describes the rights related to owning land adjacent to a lake is "littoral rights." Littoral rights pertain specifically to those who own property along a body of water that is not flowing, such as lakes or oceans. These rights typically include the use and enjoyment of the water's surface and may regulate activities like fishing, boating, and swimming, as well as access to the shoreline.

In contrast, riparian rights relate to land adjacent to flowing bodies of water, such as rivers and streams. Hereditaments refer to property rights that can be inherited but do not specifically address water rights. Land rights is a general term that does not specifically define the relationship between property ownership and water bodies. Thus, "littoral rights" is the most accurate term for the context of land adjacent to a lake.
