Summary

Keeps state water laws and existing water rights in force when federal irrigation rules apply. Federal officials must follow state rules about controlling, taking, using, or sharing irrigation water. No state, the federal government, landowner, or water user loses rights to water from interstate streams because of these federal rules. Appurtenant — the water right stays with the land that is irrigated. Beneficial use — the amount and limit of the water right are based on how much water is put to useful, beneficial use.
