Blue Ribbons of the Big Sky Country Areawide Planning Organization is a voluntary organization of local governments which was designated by the Governor of Montana in May, 1975, as the water quality planning agency for the Madison and Gallatin River drainages in southwestern Montana. In June, 1975, the US. Environmental Protection Agency approved a $475,000 grant application from Blue Ribbon under provisions of Section 208 of the Clean Water Act as amended. The major goal of the Blue Ribbons program has been to devise a water quality management plan that will preserve and protect the 'Blue Ribbon' trout streams of this area, be acceptable to a majority of residents, and fulfill the requirements of Section 208. This report summarizes the study conducted by Blue Ribbons, sets forth the results and conclusions derived from the studies, and presents the Blue Ribbon Water Quality Management Plan.
