Riparian Water Rights: A Guide for California Property Owners

By: Demetria Mantalis

Undoubtedly, California water law confuses many people. Consequently, developers and land buyers must pay close attention to these complex rules. By understanding your riparian water rights, you can provide massive benefits for your property.

Generally, California uses many different water laws to serve its people and environment. However, these specific property rights offer unique advantages to landowners who know how to use them effectively.

What Are Riparian Water Rights?

Specifically, riparian water rights apply when your property shares a boundary with surface water. For example, this includes a natural lake, river, or creek. Therefore, in these cases, the law grants you a right to use that flowing water.

Nevertheless, you must follow certain rules. Specifically, Article X, Section 2 of the California Constitution adds specific conditions. Consequently, it states that you must use all water for “reasonable and beneficial” purposes. So, what exactly does this mean?

Defining Reasonable and Beneficial Use

Typically, the state views water use as “reasonable” based on social norms. Furthermore, officials look at local customs and your overall efficiency. Additionally, they consider alternative options and environmental impacts.

Conversely, a “beneficial” use serves the highest needs of a community. For instance, examples include agricultural, mining, urban, or industrial activities. Specifically, watering your crops qualifies as a beneficial use. However, draining a creek to fill your private swimming pool does not meet this standard.

How These Rights Differ From Others

Interestingly, riparian water rights stand apart from other California water laws. Most importantly, they take priority over competing claims. Furthermore, you do not need a permit from the State Water Resources Control Board.

Additionally, you will not lose these rights simply by failing to use the water. Instead, the right ties directly to your land ownership. Thus, holding the property title keeps your legal standing completely secure.

Can You Lose Your Water Access?

Generally, you cannot transfer these rights without selling the land. However, sellers can choose to split the rights from the property. For example, a seller might sell the land but keep the water access for themselves.

Additionally, subdividing a property can cause serious problems. Specifically, if a new parcel loses its physical connection to the water, it loses its rights. Consequently, once lost, property owners rarely get these riparian water rights back.

Appropriative and Prescriptive Rights

Of course, California offers other legal options, like appropriative and prescriptive rights. However, these alternatives rely on strict permitting processes. Furthermore, they do not attach to a specific land title.

While you can acquire water access through these other methods, they lack certainty. Ultimately, only riparian water rights guarantee that your water comes directly from your own backyard.
