Book Description

The Heart River drainage basin of southwestern North Dakota comprises an area of 3,365 square miles and lies within the Missouri Plateau of the Great Plains province. Streamflow of the Heart River and its tributaries during 1949-58 was directly proportional tot he drainage area. After the construction of Heart River Butte Dam in 1949 and Dickinson Dam in 1950, the mean annual streamflow near Mandan was decreased an estimated 10 percent by irrigation, evaporation from the two reservoirs, and municipal use. This investigation of sedimentation and chemical quality of the surface water of the Heart River basin was needed for planning the development, management, and use of the water resources of the area.
