Lake Tschida (Heart Butte Reservoir)

Lake Tschida (Heart Butte Reservoir) is located in southwestern North Dakota approximately 15 miles south of Glen Ullin. The lake was created in 1949 when Heart Butte Dam on the Heart River was completed. The dam and reservoir are managed by the U.S. Bureau of Reclamation for downstream flood control and irrigation. Recreation areas around the lake offer fishing, boating, camping, and swimming.

According to the book Morton Prairie Roots, edited by M.P. Peterson and published in 1975, Lake Tschida was named after Michael Tschida, Sr. He devoted much time to promoting the construction of the Heart Butte Dam. The resulting reservoir was named Lake Tschida as an honor to him. Mr. Tschida was born in Vienna, Austria, in 1866 and came to North Dakota in 1890.

The U.S. Geological Survey publishes discharge and water-quality data for the Heart River and elevation and water-quality data for Lake Tschida in annual Water Data Reports (see Volume 1, Surface Water).
