Daldykan

The Daldykan (Далдыкан or Долдыкан Doldykan ) is a river close to Norilsk in Taymyrsky Dolgano-Nenetsky District, Krasnoyarsk Krai in Russia, a right tributary of the Ambarnaya. It is 29 km long, and has a drainage basin of 98.4 km2.

The Daldykan has been regularly polluted by nickel industry, namely from Nornickel; as a result the river's water has turned red.
