What rights allow property owners access to non-maritime water bodies?

Riparian rights are the correct answer as they refer specifically to the rights of property owners whose land is adjacent to flowing water bodies such as rivers and streams. These rights allow these owners to use the water for various purposes, including fishing, irrigation, and recreational activities. Riparian rights are a crucial aspect of property law as they establish the relationship between land and water sources, ensuring property owners have access to the water while also considering ecological balance.

In contrast, littoral rights pertain to properties that border non-flowing water bodies like lakes or oceans. Percolating water rights involve the use of groundwater, which is not relevant to the context of accessing water bodies. Subsurface rights refer to the rights to minerals and resources beneath the property and do not relate to water access. Thus, riparian rights are specifically designed to grant access and use of flowing water bodies, making them the appropriate choice for this question.
