The Oahe Dam (/ oʊ ˈ ɑː h iː /) is a large earthen dam on the Missouri River, just north of Pierre, South Dakota, United States.Begun in 1948 and opened in 1962, the dam creates Lake Oahe, the fourth-largest man-made reservoir in the United States.
Lake Oahe (/ oʊ ˈ w ɑː. h iː /) is a large reservoir behind the Oahe Dam on the Missouri River; it begins in central South Dakota and continues north into North Dakota in the United States. The lake has an area of 370,000 acres (1,500 km 2 ) and a maximum depth of 205 ft (62 m). [ 1 ]
Below are the reservoirs (artificial lakes) in the world with a surface area exceeding 500 km 2 (190 sq mi). Reservoirs can be formed conventionally, by damming the outlet of a canyon or valley to form a lake; the largest of this type is Ghana's Lake Volta, with a water surface of 8,500 km 2 (3,300 sq mi).

On May 7, the lake was at 114% of its historical average level. The so-called bathtub ring that clearly outlined the lake in 2022 — so stark it was visible from space — had disappeared by 2024.
For example, a small dam, two hydroelectric plants, and locks on the outlet of Lake Superior make it possible to artificially control the lake level. Certainly, the great majority of the lake is natural. However, the control of water that can be held in reserve means a portion of the vast lake functions as a reservoir.
