Estimated 1996--97 and long-term average annual loads for suspended sediment and selected trace metals in streamflow of the upper Clark Fork Basin from Warm Springs to Missoula, Montana
Technical Report
·
OSTI ID:675948
The report presents annual load estimates for suspended sediment and selected trace metals in streamflow at 12 sites in the upper Clark Fork basin from Warm Springs to Missoula during water years 1996-97. Annual constituent loads were calculated using constituent concentrations measured in periodically collected samples, data from daily suspended-sediment and streamflow records, and regression relations. The resulting loads are summarized to provide a spatial characterization of sediment and metals inputs during 1996-97. Methods used to calculate loads are presented for suspended sediment, total-recoverable copper, lead, and zinc, and dissolved copper.
