The Patuxent River was first recognized by the State of Maryland as a valuable natural resource, worthy of protection, in the Patuxent River Watershed Act of 1961. This legislation declared that "flood prevention, land conservation, erosion control and protection from urban development within the watershed is a public benefit and conducive to the public health, safety, and welfare." In 1968, the river was designated one of Maryland's scenic rivers. In response to the legislation, M-NCPPC developed a master plan "to preserve and protect the unique natural and historical resources... while providing compatible recreational activities for the public." The Commission embarked on a land acquisition program with funding principally from Program Open Space, Maryland's nationally-acclaimed land preservation program. In Prince George's County, the Commission owns more than 7,000 acres of parkland that protect the natural resources and preserve the scenic character of the river.
