Map of the Osage River watershed showing the Niangua River
The Niangua River // is a 125-mile-long (201 km) tributary of the Osage River in the Ozarks region of southern and central Missouri in the United States. Via the Osage and Missouri rivers it is part of the watershed of the Mississippi River.
The Niangua River is formed in Webster County by the confluence of its short east and west forks, and flows generally northward through Dallas, Laclede and Camden counties, past Bennett Spring, Lake Niangua, and Ha Ha Tonka State Parks. It flows into the Osage River as an arm of the Lake of the Ozarks, which is formed by the Bagnell Dam on the Osage. As part of the lake it collects the Little Niangua River.
