Salt Lakes in Russia and Kazakhstan48.7N 47.4E
White salt lakes of various sizes dot the brown landscape of Russia (far left) and Kazakhstan, not far from the Caspian Sea. The green area in the bottom left corner is a part of the vegetated lands along the Volga River.
The rounded lake near the center of the left edge is Lake Elton, a salt lake in Volgograd Oblast, Russia, near the border with Kazakhstan. It has an area of 150 km² and is from 0.3 to 0.6 m deep.
Near the bottom edge is Lake Baskunchak, a salt lake of 115 km² in Astrakhan Oblast, Russia, located about 270 km north of the Caspian Sea and 53 km east of the Volga. The surface elevation of the lake is 21 m below sea level.
It is fed by a river that draws from an area of 11,000 km². The salinity of the lake is about 300 g/l. Its very pure salt (99.8 % NaCl) covers 80 % of Russia’s salt production.
