Zarafshan River (also Zaravshan or Zarafshon, Tajik: Дарёи ЗарафшонDaryai Zarafshon, Uzbek: Zeravshon, from the Persian word zar-afshān, زرافشان, meaning "the spreader of gold") is a river in Central Asia. Its name, "spreader of gold" in Persian, refers to the presence of gold-bearing sands in the upper reaches of the river. To the ancient Greeks it was known as the Polytimetus. It was also formerly known as Sughd River.
Tajikistan aims to construct several hydro-electric power stations on Zerafshan River and has signed the MOU in November 2013 with Zarvon Corporation for the financing and construction of the plants. All previous MOU's have been voided.
