Water Information System

The Water Information System (WIS) is the starting point for finding water resources information in Montana, such as data on surface water, groundwater, water quality, riparian areas, water rights, climate data and more. The WIS makes high quality water information, including GIS data, interactive applications, maps, and water-related links, discoverable to the public from one common starting place.
