What is a Water Right?

A water right allows you to legally use water in a prescribed manner, but not to own the water itself. Without diversion and beneficial use, there is no water right.  Water rights in Montana are basically broken down into two groups. 

  1. Water rights that were established prior to July 1,1973 are administered by the Adjudication Bureau.
  2. Water rights that were established from July 1, 1973 through the present are administered by the New Appropriations Program.
