Course

The Heart River 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 generally eastwardly through Stark County to Gladstone, past Belfield and South Heart, through the Patterson Reservoir and past Dickinson.

It is joined by the Green River at Gladstone, and turns east-southeastward into Grant County, passing through Lake Tschida, which is formed by the Heart Butte Dam. Below this dam, the river turns northeastward into Morton County, where it joins the Missouri River at Mandan.
