Heart Butte Dam

Heart Butte Dam is an embankment dam in Grant County that crosses the Heart River and rises to approximately 142 feet (43 meters) high. The structure creates a large reservoir that supplies water primarily for agricultural irrigation across the surrounding region.

The embankment dam was completed in 1949 by the United States Bureau of Reclamation to manage water resources in southwestern North Dakota. The project arose from the need to prevent flooding and support agricultural growth in the region.

The reservoir carries the name of Michael Tschida Sr., the first mayor of Glen Ullin, who advocated for the dam construction in the Grant County area. His name is tied to the place's story and reflects how the local community shaped the development of this water management facility.

The lake features six primitive campgrounds equipped with wells and vault toilets for overnight visitors. The best time to visit is during warmer months when access to facilities and trails is most convenient.

The dam features a morning-glory type spillway, a distinctive outlet design that looks like a giant drain when water flows over it. This system automatically channels excess water away when the reservoir reaches full capacity without needing gates or controls.
