Water-quality, bed-sediment, and biological data (October 1999 through September 2000) and statistical summaries of data for streams in the Upper Clark Fork Basin, Montana. Open-File Report 01-379.

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 1999 through September 2000 (water year 2000). Data for 14 bed-sediment and 14 biological stations were obtained in September 2000. 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 suspended-sediment discharge are given for three stations. Bed-sediment 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 water-quality, bed-sediment, and biological data are provided tor the period of record at each station since 1985.
