How to read this map
The Niagara River is about 53 km (33 mi) long and drains a basin of about 665,000 km² (257,000 sq mi). Its average discharge is about 6 m³/s (205 cu ft/s). It rises at Lake Erie and flows into Lake Ontario. It flows through or along the United States and Canada. Tributaries include Scajaquada Creek and Tonawanda Creek.
The highlighted blue line is the course of the Niagara River as mapped by Natural Earth. Towns and cities on the map include Toronto, Buffalo, Rochester, Hamilton, Oshawa, Kitchener, Erie and Niagara Falls.
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 course of the Niagara River come from Natural Earth, and the figures on this page from Wikidata. Natural Earth draws features at a small scale, so the line is a guide to where the Niagara River is, not a surveyed boundary.
