Mine tailings washed downstream in a massive 1908 flood and settled in the Milltown Reservoir near Missoula. Arsenic from the tailings had seeped into the groundwater supply for the nearby communities of Bonner and Milltown by the 1980s. As part of the reclamation and restoration of the Upper Clark Fork Basin, the Milltown Dam was removed, tailings deposits were shipped by rail to the BP-Arco Waste Repository, and the area is being restored.
