The Volga River

The Volga River is the longest river in Europe. It belongs to the closed basin of the Caspian Sea. Rising in the Valdai Hills 225 meters (738 ft) above sea level northwest of Moscow and about 320 kilometers (200 mi) southeast of Saint Petersburg, the Volga heads east past Lake Sterzh, Tver, Dubna, Rybinsk, Yaroslavl, Nizhny Novgorod, and Kazan. From there it turns south, flows past Ulyanovsk, Tolyatti, Samara, Saratov and Volgograd, and discharges into the Caspian Sea below Astrakhan at 28 meters (92 ft) below sea level. At its most strategic point, it bends toward the Don ("the big bend"). Volgograd, formerly Stalingrad, is located there.

The Volga has many tributaries, most importantly the Kama, the Oka, the Vetluga, and the Sura rivers. The Volga and its tributaries form the Volga river system, which flows through an area of about 1,350,000 square kilometres (521,238 square miles) in the most heavily populated part of Russia. The Volga Delta has a length of about 160 kilometres (99 miles) and includes as many as 500 channels and smaller rivers. The largest estuary in Europe, it is the only place in Russia where pelicans, flamingos, and lotuses may be found. The Volga freezes for most of its length for three months each year.
