Western water law

Western water law primarily follows the doctrine of prior appropriation, often summarized as "first in time, first in right." This means that the first person to divert and put water to beneficial use has a legal right to that water, which can be prioritized over others. Rights are generally based on a chronological system, rather than land ownership, and can be temporary or permanent. Water rights are managed through permits, licenses, and court rulings, ensuring efficient allocation amid scarcity. This legal framework aims to balance competing needs for agricultural, municipal, industrial, and environmental uses.
