Understanding the Prior Appropriation Doctrine: A Guide to Water Rights
Definition & Meaning
The prior appropriation doctrine is a legal principle that governs water rights in certain American jurisdictions. Under this doctrine, the first individual or entity to divert water from a natural source for beneficial use has the exclusive right to continue using that water. This means that among those who share access to a waterway, the earliest users have priority over later users in terms of water access and usage.

Legal Use & context
The prior appropriation doctrine is primarily used in water law, particularly in western states where water resources are scarce. It is relevant in various legal contexts, including property law and environmental law. Users may encounter this doctrine when dealing with water rights disputes, irrigation practices, or water resource management. Individuals can manage some aspects of these issues using legal forms, such as those provided by US Legal Forms, which can help in drafting agreements or filing claims related to water rights.
Key legal elements
Real-world examples
Here are a couple of examples of abatement:
Example 1: A farmer who first diverts water from a river for irrigation purposes has the right to continue using that water, even if a later farmer attempts to divert water from the same source.
Example 2: A city that establishes a water supply from a stream for its residents has priority over a new development that seeks to use the same water source (hypothetical example).
