How to read this map
Its surface lies about 502 m (1,647 ft) above sea level. Inflows include Missouri River, Cheyenne River and Cannonball River. It drains through the Missouri River. It lies in South Dakota and North Dakota.
The blue outline marks Lake Oahe as mapped by Natural Earth. Towns and cities on the map include Bismarck, Dickinson and Pierre. Labeled states and countries: North Dakota.
Greens show lower elevations; tan and brown show higher land, with pale tones toward the highest terrain. Shadows emphasize the slopes, and vertical relief is exaggerated so landforms are easier to read. Dashed lines show country borders, and fine dashed lines show state or province borders.
The relief uses Terrain Tiles (SRTM, GMTED2010 and ETOPO1 elevation data). Rivers, lakes, borders and the outline of Lake Oahe come from Natural Earth, and the figures on this page from Wikidata. Natural Earth draws features at a small scale, so the outline is a guide to where Lake Oahe is, not a surveyed boundary.
