Boulder River Watershed, Montana Study Area

The Boulder River watershed in Montana is one of many watersheds in the western United States where historical mining has left a legacy of acid mine drainage and elevated concentrations of potentially toxic trace elements in surface streams. U.S. Geological Survey scientists have completed a major assessment of the environmental effects of historical mining in the Boulder River watershed. The study demonstrated how the watershed approach can be used to assess and rank mining affected sites for possible cleanup. The study was conducted in collaboration with State and Federal land-management agencies.
