| Abstract | Water, bed sediment, and biota were sampled in streams from Butte to below Missoula as part of a program to characterize aquatic resources in the upper Clark Fork basin of western Montana. Sampling stations were located on the Clark Fork and major tributaries. Water-quality data were obtained periodically at 15 stations during October 1997 through September 1998 (water year 1998). Data for 15 bed-sediment and 15 biological stations were obtained in August 1998. The primary constituents analyzed were trace elements associated with tailings from historical mining and smelting activities. Water-quality data include concentrations of selected major ions, trace elements, and suspended sediment in stream samples. Daily values of streamflow, suspended-sediment concentration, and suspendedsediment discharge are given for three stations. Bedsediment data include trace-element concentrations in the fine-grained and bulk fractions. Biological data include trace-element concentrations in whole-body tissue of aquatic benthic insects. Quality-assurance data are reported for analytical results of water, bed sediment, and biota. Statistical summaries of waterquality, bed-sediment, and biological data are provided for the period of record at each station since 1985. |
