TheNuchcha orNuuchcha (Russian:Нучча;Yakut:Нуучча,romanized: Nuuçça) is a river in theSakha Republic (Yakutia),Russia. It is the longest tributary of theChondon. The river has a length of 243 kilometres (151 mi) and adrainage basin area of 2,410 square kilometres (930 sq mi).[1]
The Nuchcha flows north of theArctic Circle, across desolate territories of theUst-Yansky District. An abandoned village named "Batagay" was located by the riverside in its lower course.[2][3] A 2021Yakutfictional film which received an award at theKarlovy Vary International Film Festival was named Nuuchcha.[4]
The Nuchcha is a righttributary of the Chondon. It has its sources in the northern slopes of theKyun-Tas range. The river flows roughly northwards within a valley. After it leaves the mountainous terrain it heads across theYana-Indigirka Lowlandfloodplain to the southwest of theSellyakh. It flows slowly through flat terrain where itmeanders very strongly among numerous lakes. Finally the river joins the Chondon 126 km (78 mi) from its mouth.Tumat, the nearest inhabited place, is located nearly 20 km (12 mi) upstream of the confluence.[2][3]
The main tributaries of the Nuchcha are the 45 km (28 mi) longBylaat-Yurege (Былаат-Юрэгэ) and the 38 km (24 mi) long Buruuchaan-Yurege (Буруучаан-Юрюйэ) on the right, as well as the 26 km (16 mi) long Ekechan (Экэчан) on the left. The river is frozen between the beginning of October and the beginning of June. There are more than 1,300 lakes in its basin.[5]
