Supplemental arsenic data for selected streams in the Missouri River basin, Montana, 1987
Geothermal waters within Yellowstone National Park contribute arsenic to the Madison River. Concentrations ranging from 200 to 300 micrograms per liter in the Madison River near the park boundary are diluted downstream by tributary inflows to the Madison and Missouri Rivers. However, significant amount of arsenic are present in the water of the Missouri River as it enter Fort Peck Lake. A monitoring network of 24 stations was operated during 1985 and 1986 in the upper Missouri River basin to measure arsenic concentrations and arsenic discharges. Additional monitoring at nine stations was conducted during March to July 1987 to supplement the data base. This report presents data acquired from the 1987 monitoring period. (USGS)

Historical water-quality data for the Clark Fork (river) and the mouths of selected tributaries, western Montana
The Clark Fork, occupying a major drainage area in western Montana, leaves the state of Montana 's largest river. This report is a compilation of recent historical water-quality data collected by the U.S. Geological Survey on the Clark Fork and near the mouths of major tributaries. Included in the report are water-quality data collected during various time intervals since 1969 at 18 surface-water stations. Because of the large amount of streamflow and water-temperature data collected at these 18 stations and at other sites in the study area, the data are not included in the report. However, station numbers and corresponding periods of record are listed and the availability of the data is identified. (USGS)
