Water Quality


For nearly 20 years, Rai Hahn has collected water quality data from April through October on the Sun River and many tributaries. Rai’s data provides a science-based view of water quality trends over time and across the watershed. Rai often incorporates local community students, teaching them to collect and analyze water samples and about the importance of watershed health. Funding for analysis of these samples is provided by the Department of Environmental Quality Volunteer Water Quality Monitoring Program. The Bureau of Land Management and Montana State University Extension Water Quality department also provide support for this program.
