Water-quality sampling sites in the upper Clark fork Basin, Montana

Mining in the upper Clark Fork Basin has resulted in substantial effects on water quality from large amounts of waste materials enriched with metallic contaminants. The U.S. Geological Survey has collected data since 1985 to document changes in water quality that might have resulted from remediation activities.

What is a Shift-adjusted rating?

Stage-discharge relationships (ratings) are primarily developed from a graphical analysis of multiple streamflow measurements. Measurements are generally made on 8-week intervals. The frequency/interval of streamflow measurements may change based on a variety of circumstances including (but not limited to) flow conditions and rating definition.
