The Omuljowka ( Russian Омулёвка ) is a 410 km long left tributary of the Yassachnaja in northeast Siberia , in the Asian part of Russia .

The river has its source at almost 2000  m Ochandja ridge in the southern part of the Tscherski Mountains in the north of Magadan Oblast , about 130 km as the crow flies north-northwest of the city of Sussuman . Its name is derived from Omul , which in Russian refers not only to the fish species found in Lake Baikal , but also to other salmon fish of the genus Coregonus .

The Omuljowka flows with several changes of direction generally in an easterly and increasingly north-easterly direction, following the border with the Sakha Republic (Yakutia) at some distance . After passing through the valley east of Ochandja comb it passes through the Omuljowka-Mountain (Omuljowskoje srednegorje), the southern continuation of Ulachan-Tschistai comb of Tscherskigegirges in a narrow canyon-like transverse valley , then the as Omuljowka lowland (Omuljowskaja nismennost) designated southeastern part of the valley between the Tscherski and Moma mountains . In this area the Omuljowka forms a large number of river arms. In the following breakthrough valley through the southern, there still almost 1400  m part of the Moma Mountains, the river reaches the Republic of Sakha and finally the Kolyma lowlands . There it flows in an easterly direction, for the last few kilometers in a northerly direction to the confluence with the Yassachnaja, 152 kilometers above its confluence with the Kolyma and about 70 km as the crow flies south of Syrjanka .

The catchment area of ​​the Omuljowka covers 13,500 km². Its main tributaries are the Omtschiktschan (Russian Омчикчан , length 151 km) from the left and Urultun ( Урультун , 130 km) and Inanja ( Инанья , 92 km) from the right.

Today there are no towns in the entire catchment area of ​​the river. On the upper reaches of the river which was ewenische reindeer herders settlement Kuntek, which was abandoned in the 1990s. It was accessible via a road from the mining area around the settlement of Burkandja north of Sussuman, which, however, no longer exists either.
