Course

The Ustya starts at the border of Kotlassky District and Velikoustyugsky district, flows to the west, in part forming the boundary between the oblasts, then turns north-west and crosses into Krasnoborsky District. There it turns west and enters Ustyansky District, where the major part of its course is located. It first turns south and descends, turns west and accepts a major left tributary, the Kizema. Then it sharply turns north-west, and in the selo of Bestuzhevo, after the confluence with Veryuga (right) turns south again. Oktyabrsky, the district center of Ustyansky District, is located on the left bank of the Ustya. Downstream of Oktyabrsky, the Ustya turns north-west again and enters Velsky District. There it accepts a major tributary, the Kokshenga, from the left, from its confluence with the Vaga. The mouth of the Ustya is in the village of Vlasovskaya.
