Water rights, deriving from legal entitlements to water resources, equip landowners with authorized access to use water in or near their property. In the United States, this is governed distinctly in eastern states and western states. The former operates under the riparian doctrine-allowing use by adjacent landowners-while the latter implements the prior appropriation doctrine-granting rights to the first user.
Navigating these regulations is crucial for lawful water usage and appropriate property management, as it varies across states. Riparian rights are bestowed upon landowners whose property is adjacent to flowing bodies of water like rivers or streams. As a general rule, landowners can utilize the water as long as it doesn't detrimentally affect neighbors upstream or downstream. Moreover, for non-navigable waterways, the land underneath belongs to the owner up to the waterway's exact midpoint.
In contrast, littoral rights are associated with property bordering large, navigable bodies of water-lakes and oceans. These landowners have unrestricted access to the water area but own the land only up to the median high-water mark.
Crucially, water rights are appurtenant-they stick with the land and not the owner. Thus, when a waterfront property changes hands, so do the water rights.
Owners can use the water in multiple ways, including for drinking, bathing, and irrigation, among other domestic purposes. However, the authority to pump or remove water from a flowing river or stream may be limited based on riparian rights and local regulations.
In some cases, landowners could apply for water diversion rights, allowing water to be transferred from its source. Such rights may support commercial endeavors like mining operations or agricultural irrigation. Yet, continuity in using the water is imperative, otherwise the rights may expire after a stipulated period.
In the eastern U.S., landowners must comply with the riparian doctrine, granting them a "reasonable use" of neighboring water bodies. Still, a government-regulated riparian system is in place where individuals or corporations must secure permits for projected water usage.
This differs from the western U.S., where the prior appropriation doctrine is more prevalent. Birthed during the 19th-century western settlements, anyone who first appropriates a water source for beneficial use gets the right to continue its usage.
Over time, certain water rights have experienced restrictions with regulations like the Clean Water Act, Endangered Species Act, and the National Environmental Policy Act. This shift has led to significant friction between the federal government and the western states.
Water rights, including riparian rights for flowing waters and littoral rights for large bodies of water, allow landowners access to water near their property. Understanding these rights and complying with local laws, ideally with professional support, is a requisite for protecting these rights.
