Fifteen streams in the Lower Gallatin Watershed do not meet state water quality standards set by the Montana Department of Environmental Quality.

These streams are considered “impaired” because they contain sediment, nutrients, and/or E. coli at levels that impair the use of that water for beneficial purposes such as irrigation or recreation.
