Heart River
From Academic Kids
The Heart River is a tributary of the Missouri River, approximately 180 mi (290 km) long, in western North Dakota in the United States.
It rises in the prairie country of Billings County, in the Little Missouri National Grassland near the south unit of Theodore Roosevelt National Park. It flows east through the Patterson Reservoir and past Dickinson. At Gladstone, it is joined by the Green River, and flows ESE, through Lake Tschida formed by the Heart Butte Dam. It turns northeast, and joins the Missouri at Mandan.
