NorthWestern Energy developed a water quality and biological monitoring program for the Missouri and Madison Rivers to identify long-term
trends and spatial variation of water quality and biological parameters throughout the system, as well as to evaluate the effects of operation and maintenance of the hydroelectric facilities on these rivers. This page provides detailed information about this program and its components.
For more information, see our Missouri-Madison Water Quality Program brochure.
