Fort Peck Lake Map
Fort Peck Lake is a lake in the United States. This map shows the lake outlined in blue on shaded relief, with the rivers, borders and towns around it.

How to read this map
Inflows include Missouri River and Big Dry Creek (Montana). It drains through the Missouri River. It lies in Montana.
The blue outline marks Fort Peck Lake as mapped by Natural Earth.
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 Fort Peck Lake 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 Fort Peck Lake is, not a surveyed boundary.

The blank version keeps the mapped features and removes the place labels. Download it for a geography worksheet or practice identifying the features.
