The Kyllach ( Russian Кыллах , Yakut Кыыллаах ) is a 423 km long left tributary of the Sededema in northeast Siberia , in the Asian part of Russia .

The Kyllach rises on the almost 1000  m high Changas-Tas mountain range on the Alaseja plateau , almost directly on the northern polar circle and about 120 km as the crow flies southeast of the Belaja Gora settlement on the Indigirka . It flows first in a north-easterly, then mostly strongly meandering in a south-easterly direction up to its confluence on the western edge of the Kolyma lowland in the left Kolyma tributary Sededema, 274 kilometers above its confluence and about 125 km southwest of the small town of Srednekolymsk .

The catchment area of the Kyllach covers 5080 km². The largest tributaries are the Esseljach (Russian Эселях , also Egeljach; length 62 km) from the right and Ucha-Jurjage ( Утча-Юряге , 72 km) and Chotu-Sala ( Хоту-Сала , 70 km) from the left.

There are no settlements in the entire catchment area of ​​the river. The Kyllach flows slightly above the confluence of the Chotu-Sala in the western part of Srednekolymski ulus of the Sakha Republic (Yakutia) , from there to the confluence it marks the border to the neighboring Werchnekolymski ulus for almost 200 kilometers .
