A Buyers Guide to Montana Water Rights
By Jacy Suenram of Suenram and Bergeson Law Offices
Water right holders possess the right to use the water. Water rights are afforded the protection of the United States and Montana Constitutions, just like any other property right. The governing law for adjudication of water rights and resources in Montana is the prior appropriation doctrine – applying the rule of “First in Time is First in Right”. The prior appropriation doctrine originated in the Western states to accommodate the irrigation and mining needs of a developing west. Under the prior appropriation doctrine, a water user must have a water right to appropriate water from a stream or groundwater source.
As such, even if a stream or ditch runs through your piece of property, if you do not have an established water right for use of that water, diversion by you violates Montana law and doing so could result in a trip to the District Court or Montana Water Court! As such, water rights in Montana are claimed based on when the water was put to beneficial use, also known as its “priority date.” Historical documentation and institutional knowledge support the priority dates of Montana water right claims. The importance of the priority date is the ability to "call" water by senior water right holders. Calling water means that the senior water right holder can require the junior water right holders to stop diverting water to fulfill the senior water right holders’ needs. In a nutshell, not all water rights are created equal. Some of the senior water rights in Montana date back to the 1860s!
When buying water rights in Montana, the general rule of thumb is that “water rights run with the land.” While this is the usual practice, water rights can be transferred to a new place of use. Any change in the purpose, place of use, acres irrigated, or place of diversion of a water right must first be approved by the Montana Department of Natural Resources and Conservation (“DNRC”). Before 1973, if you wanted to change the place of use, purpose, or point of diversion, you were able to do so without having to file for the change. The burden of showing your change caused a negative impact was on the party negatively impacted. On July 1, 1973, the Montana Water Use Act became effective. The Montana Water Use Act did not alter basic water right concepts, but tasked the DNRC with overseeing the procedure for acquiring and changing water rights. If you want to change a water right now, the burden is on you to prove it will not interfere with anyone else’s water use. Filing water rights in Montana is governed by the DNRC and the adjudication of water rights is handled by the Montana Water Court.
