Karatag

The Karatag or Qoratagʻ () is a river of northwestern Tajikistan and eastern Uzbekistan. It flows through Shirkent National Park and flows down the south slopes of the Gissar mountain range. At its confluence with the Toʻpolondaryo, the Surxondaryo is formed. The river is long. Large seismic landslides occur in the river basin and it also contains several glacial lakes. Upstream from the confluence with the Payron, the Karatag is called "Diakhandara". Another tributary is the Zambar. The Diakhandara Glacier, which fed the upper course of the Karatag, has fully melted.
