Chetyrekh

The Chetyrekh is a river in Krasnoyarsk Krai, Russia. Its source is in the Byrranga Mountains. It flows across tundra regions into the Staritsa, a branch of the Pyasina that discharges into the Pyasina Bay of the Kara Sea north of the main mouth of the Pyasina. It is 128 km long, and has a drainage basin of 1010 km2.

The Chetyrekh freezes up in late September&mdash;early October and stays under the ice until June. Formerly this river was known as Dolgiy Brod River, but its name was changed after the 1917 Russian Revolution.
