The Knife River is a tributary of the Upper Missouri River in North Dakota, spanning 120 miles in length. The river holds significant historical and cultural importance for the Northern Plains Native Americans, as it was a vital resource for transportation, food, and shelter. Today, the river primarily serves as a source of irrigation for agriculture and as a recreational spot for fishing and water sports. The river runs through several reservoirs, including Lake Sakakawea, which was created by the Garrison Dam on the Missouri River. The dam is the largest hydroelectric power producer in the state and provides flood control, irrigation, and recreation. The river also flows through the Knife River Indian Villages National Historic Site, which preserves the site of a Hidatsa village dating back to the 18th century.
