The Nuchcha or Nuuchcha (Russian: Нучча; Yakut: Нуучча, Nuuçça) is a river in the Sakha Republic (Yakutia), Russia. It is the longest tributary of the Chondon. The river has a length of 243km (151miles) and a drainage basin area of 2410km2.
The Nuchcha flows north of the Arctic Circle, across desolate territories of the Ust-Yansky District. An abandoned village named "Batagay" was located by the riverside in its lower course. A 2021 Yakut fictional film which received an award at the Karlovy Vary International Film Festival was named Nuuchcha.[1]
The Nuchcha is a right tributary of the Chondon. It has its sources in the northern slopes of the Kyun-Tas range. The river flows roughly northwards within a valley. After it leaves the mountainous terrain it heads across the Yana-Indigirka Lowland floodplain to the southwest of the Sellyakh. It flows slowly through flat terrain where it meanders very strongly among numerous lakes. Finally the river joins the Chondon 126km (78miles) from its mouth. Tumat, the nearest inhabited place, is located nearly 20km (10miles) upstream of the confluence.[2] [3]
The main tributaries of the Nuchcha are the 45km (28miles) long Bylaat-Yurege (Былаат-Юрэгэ) and the 38km (24miles) long Buruuchaan-Yurege (Буруучаан-Юрюйэ) on the right, as well as the 26km (16miles) 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.[4]
