The Gusinaya (Russian: Гусиная; Yakut: Хаастаах, Xaastaax) is a river in the Sakha Republic (Yakutia), Russia. It has a length of 278km (173miles) and a drainage basin area of 5980km2.
The river flows north of the Arctic Circle, across territories of the Allaikhovsky District marked by permafrost. There are no settlements along its course, only some hunting huts.
The Gusinaya has its sources in the southeastern shore of Empe-Talalakh (Эмпе-Талалах) lake of the northern end of the Yana-Indigirka Lowland, East Siberian Lowland. The river flows roughly southeastwards across partially swampy tundra until the confluence of the 35km (22miles) long Alyn-Ergiter-Salaata (Алын-Эргитэр-Салаата), after which it turns eastward. Its channel meanders strongly all along among numerous lakes, some of them quite large. In the lower course the river divides into channels and turns southeast and then northeast, before emptying into the Gusinaya Bay of the East Siberian Sea to the south of the mouth of the Volchya.[1] [2]
The main tributaries of the Gusinaya are the 115km (71miles) long Chaikhana (Чайхана) and the 110km (70miles) long Mutnaya (Мутная) on the right. There are about 3,000 lakes in the basin, totaling an area of 418km2. The river is frozen between the beginning of October and mid June.[1] [3]
