WATER RIGHTS
Water Management | Watersheds | Water Quality | Water Rights | Wetlands | Ground Water | Aquatic Life | Stormwater | Buffers

Water rights in Montana are guided by the prior appropriation doctrine, that is, first in time is first in right. A person’s right to use a specific quantity of water depends on when the use of water began. The first person to use water from a source established the first right, the second person could establish a right to the water that was left, and so on. During dry years, the person with the first right has the first chance to use the available water to fulfill that right. The holder of the second right has the next chance. Water users are limited to the amount of water that can be beneficially used. In Montana, the term “beneficial use” means, generally, a use of water for the benefit of the appropriator, other persons, or the public, including but not limited to agricultural (including stock water), domestic, fish and wildlife, industrial, irrigation, mining, municipal, power, and recreational uses.
