Water planning is an art and a science. The vision for water use in many western states, including Montana, is outlined by a State Water Plan that recommends ways to meet current and future water uses. Plans often include water use and availability data and projections. They may incorporate conservation targets.


2015 Montana State Water Plan


The 2015 State Water Plan is a synthesis of the vision and efforts of regional Basin Advisory Councils (BACs) established in Montana’s four main river basins: the Clark Fork/Kootenai, Upper Missouri, Lower Missouri, and the Yellowstone. DNRC has pulled together the work of the 80 members of the four BACs into a plan that addresses water management issues on a statewide basis.
