ProgressionTaui → Sea of Okhotsk

The Chyolomdzha is the longest tributary of the Taui (Kava) and flows across an uninhabited area, part of the Magadan Nature Reserve.[3] The name of the river originated in the Even language.[4]

Course

The source of the Chyolomdzha is in the Upper Kolyma Highlands. The river heads in a roughly southern direction, flowing fast across mountainous terrain, then it turns to the southeast descending into a floodplain where it slows down and splits into multiple sleeves, while the channels form meanders. Finally the Chyolomdzha joins the left bank of the Taui in the wide Kava-Taui Plain, 66 kilometres (41 mi) from its mouth in the Sea of Okhotsk.[3][1][5]

The river freezes yearly between early October and late May.[5] Its main tributary is the 124 km (77 mi) long Burgagylkan (Бургагылкан), joining its left bank in the lower course.[2]

Fauna

Different species of salmonids live in the waters of the Chyolomdzha, including chum salmon, malma, coho salmon and kundzha, as well as grayling.

The banks of the river provide a habitat for the Blakiston's fish owl, an endangered species.[6]
