The Department of Environmental Quality (DEQ) invites the public to an open house to share updates on a multi-year water quality study for the middle segment of the Gallatin River, from Yellowstone National Park to Spanish Creek. DEQ, Gallatin River Task Force, Montana Bureau of Mines and Geology, Gallatin Canyon Water and Sewer District, and Montana State University will have staff available to answer questions about studies and the ways DEQ and the community can contribute to a healthier Gallatin River.
