How to read this map
The Selenga River is about 1,020 km (636 mi) long and drains a basin of about 447,000 km² (173,000 sq mi). Its average discharge is about 935 m³/s (33,000 cu ft/s). It rises at Delgermörön and flows into Lake Baikal. It flows through or along Mongolia and Russia. Tributaries include Eg River, Dzhida, Temnik, Orkhon River, Chikoy, Khilok River, Uda and Delgermörön.
The highlighted blue line is the course of the Selenga River as mapped by Natural Earth. Towns and cities on the map include Irkutsk, Ulan-Ude, Angarsk, Usolye-Sibirskoye, Erdenet and Darkhan.
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 Selenga 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 Selenga River is, not a surveyed boundary.
