Garrison Dam is an earth-fill embankment dam on the Missouri River in central North Dakota, United States. Constructed by the U.S. Army Corps of Engineers from 1947-53 at over 2 miles (3.2 km) in length, the dam is the fifth-largest earthen dam in the world. The reservoir impounded by the dam is Lake Sakakawea, which extends to Williston and the confluence with the Yellowstone River, near the Montana border.
