Buor-Yuryakh (Chondon)

The Buor-Yuryakh (Буор-Юрях; Буор-Үрэх, Buor-Ürex) is a river in the Sakha Republic (Yakutia), Russia. It is the second largest tributary of the Chondon. The river has a length of 170 km and a drainage basin area of 1040 km2.

The Buor-Yuryakh flows north of the Arctic Circle, across desolate territories of the Ust-Yansky District. The name of the river comes from the Yakut "Буор Үрэх" "Buor" = earth, clay / "Yurekh" = river.

Course
The Buor-Yuryakh is a left tributary of the Chondon. It has its sources in the northeastern slopes of the Kyundyulyun at the feet of 534 m high Gory Krest mountain. The river flows roughly eastwards across a floodplain among numerous lakes forming meanders all along its course. Finally the Buor-Yuryakh joins the Chondon 354 km from its mouth.

Tributaries
The main tributary of the Buor-Yuryakh is the 36 km long Sakhsyr-Yuryege (Сахсыр-Юрэгэ) that joins its left bank 112 km before the confluence with the Chondon. There are more than 400 lakes in the river basin with a total area of 34 km2. The Buor-Yuryakh is frozen between the end of September and early June.
