Khasyn

The Khasyn (Хасын) is a river in Magadan Oblast, Russian Far East, a tributary of the Arman. It is 115 km long, with a drainage basin of 3900 km2. The R504 Kolyma Highway runs by the riverside along a 40 km long stretch.

The name of the river originated in the Even language word "Khesen", meaning "herd".

Course
The river has its source in the Kolyma Mountains, 15 km to the north of Karamken at an elevation of about 800 m. It flows initially southwards with many rapids across a mountainous area, bending subsequently to the SSW and holding that direction until its mouth. Finally the Khasyn joins the left bank of the Arman 12 km from its mouth in the Sea of Okhotsk.

Besides of the abandoned village of Karamken, the settlements of Palatka, Khasyn, Stekolny and Splavnaya are located by the banks of the river. Magadan's Sokol Airport is located 8 km to the east of the river.

The main tributaries of the Khasyn are the 55 km long Nelkandzha (Nyulkandzha) and the 42 km long Chalbyga from the right, as well as the 50 km long Uptar that joins it from the left. The Khasyn is frozen between October and May. The river is not navigable.

Fauna
The river is a spawning ground for salmon, both freshwater and anadromous, such as the coho salmon. Other fish species in the river are grayling and Dolly Varden char.
