What are water quality standards and beneficial uses?
The Montana Board of Environmental Review, a citizen panel appointed by the governor, establishes water quality standards and designates beneficial uses of rivers, lakes and streams. Beneficial uses can be grouped into three broad categories: Recreation includes swimming, boating and other water activities that involve physical contact with water. Aquatic life includes the plants and animals that are the basis of a healthy aquatic ecosystem. Fish, of course, are aquatic life. However, fisheries are listed as a separate beneficial use due to their recreational and economic importance. Waterfowl and fur bearers are also considered beneficial uses. Water supply encompasses domestic, municipal, industrial and agricultural uses. Every water body has designated beneficial uses based on the Montana Water Classification System.
