The Cannonball River is a 126-mile-long tributary of the Missouri River, flowing through North Dakota. The river is named after the cannonball concretions found along its banks. The river has played an important role in Native American history, serving as a primary water source for the Standing Rock Indian Reservation. The river is also home to several reservoirs and dams, including the Heart Butte Dam and the Cannon Ball-Mandan Canal. These structures provide hydroelectric power, irrigation, and flood control to nearby agricultural lands. The Cannonball River also offers recreational activities such as fishing, boating, and camping. However, the river gained national attention during the 2016 Dakota Access Pipeline protests, where protesters argued that the pipeline would harm the river and the Standing Rock Sioux Tribe's water supply.
