Dus-Khol lake, Salt lake in Tandinsky District, Tuva, Russia

Dus-Khol lake is an oval salt lake, 1.4 km long and 0.3–0.5 km wide, covering 0.55 km² at 707 m elevation in the Tuvan basin. Its gently sloping shores are sandy in places and treeless, and two saline springs on the southern and eastern banks feed the brine.

The lake's Russian name Svatikovo appears on maps of the Russian Empire and was later replaced by the Tuvan Dus-Khol. In 1968 the hydrogeologist E. V. Pinneker described its brine in the study Mineral Waters of Tuva, published in Kyzyl. Sanatoria and the camping base "Center of Asia" were then built on its shore, making the lake a resort of the Tuvan Republic.

Dus-Khol means "salt lake" in Tuvan, and Russians also call it Svatikovo. The water is compared to the Dead Sea, and several sanatoriums stand by the shore. The "Center of Asia" campsite on the bank has eight two-person cabins, a yurt café and a beach area.

Access to the lake is through settlements in Tandinsky District, and visitors must follow strict conservation regulations. Plan your visit around weather conditions typical of southern Siberia, as terrain and temperature vary seasonally.

The brine is a magnesium-sodium chloride mix rich in bromine, with salinity rising from 100 g/l at the shore to 280 g/l at the bottom. Solar heating makes the deep brine reach 41 °C while the surface stays near 23 °C, the strongest such effect among the local lakes Kak-Khol and Khadyn.
