What Are Water Rights?

Water rights are a type of interest that may attach to real estate ownership and pertain to the rights to use adjacent bodies of water. Different types of waters rights exist based on various forms of water that border or exist on a property.

How Water Rights Work

Riparian rights are awarded to landowners whose property is located along flowing bodies of water such as rivers or streams. Landowners typically have the right to use the water as long as such use does not harm upstream or downstream neighbors. In the event the water is a non-navigable waterway, the landowner generally owns the land beneath the water to the exact center of the waterway.

Littoral rights pertain to landowners whose land border large, navigable lakes and oceans. There are tides and currents that affect these bodies of water, but they do not flow by the land in the manner of streams and rivers. Landowners with littoral rights have unrestricted access to the waters but own the land only to the median high-water mark.

Water rights are appurtenant, meaning they run with the land and not to the owner. In other words, if an oceanfront property is sold, the new owner gains the littoral rights and the seller relinquishes his or her rights.

Key Takeaways

  • Water rights give access to bodies of water adjacent to one's property.
  • Riparian rights are those allowing access and usage of flowing bodies of waters like rivers and streams. Littoral rights allow access to lakes, seas, and oceans.
  • Water rights are regulated state-by-state and each municipality can enforce stricter provisions on water access and usage.

What Water Rights Mean In Relation to Land Usage

Riparian rights can differ from littoral rights. An owner who holds land that includes a riverbank that borders on a flowing river will be able to make use of the water for needs such as drinking, providing water for animals, bathing or watering gardens. These would count as domestic uses that are permitted. Riparian rights might not allow the water to be pumped or otherwise removed from the flowing river or stream.

Depending on local laws, the water might not be used to irrigate land or for commercial needs. Some localities may allow for certain irrigation uses of the water. It may be possible to apply for water diversion rights that would allow for the transport of water away from its source. That would permit usage of the water for commercial purposes such as for mining operations or the irrigation of lands for agricultural operations.

Each state and municipality will have regulations and limits on the extent of water diversion that may be permitted. Those limits are intended to reduce the impact that water removal could have on the surrounding environment. Water diversion rights may include stipulations that use of the water must be consistently maintained, or the rights will expire after a defined period of time.
