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 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.
