A few of the residents also wondered what was in the small reservoir to the south that dammed the Clark Fork River. The river had received mining and milling wastes for over 100 years from the Butte and Anaconda areas 190 to 240 km upstream. In 1975, Bailey, as part of her Master of Science at the University of Montana, sampled reservoir sediments (Bailey, 1976) and found elevated concentrations of copper, lead and zinc (Bailey and Weisel, 1976). However, she did not analyze the sediment for arsenic.

The drainage basin of the Clark Fork, an eastern tributary of the Columbia River, has been affected for long distances by the copper mining and ore treatment processes that were conducted at Butte and Anaconda, Montana, for about 125 years, ending in 1982. Conditions in this stream have been described (28). A more recent paper (29) pointed out that many streams in mineralized areas had relatively high metal concentration prior to the beginning of niining activity.
