Lake Saint Clair Map
Lake Saint Clair is a lake across Canada and the United States, covering about 1,110 km² (430 sq mi), with a maximum depth of 3 m (11 ft). This map shows the lake outlined in blue on shaded relief, with the rivers, borders and towns around it.
How to read this map
Its surface lies about 175 m (574 ft) above sea level. Inflows include St. Clair River, Thames River, Chenail Ecarté (The Snye), Johnston Channel, Salt River and Clinton River. It drains through the Detroit River. It is shared by Canada and the United States.
The blue outline marks Lake Saint Clair as mapped by Natural Earth. Towns and cities on the map include Detroit, Toledo, Flint, Ann Arbor, Sarnia, Saginaw, Bay City and Pontiac.
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 Saint Clair 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 Saint Clair is, not a surveyed boundary.
