The name of the district originates from the Ustya River.
Geography
The district is located on the left bank of the Northern Dvina River. Most of the district's territory belongs to the basin of the Ustya River and its tributaries. The main tributaries of the Ustya are the Kizema (left), the Obil (right), and the Kokshenga (left).
Minor parts of the district in the east and in the north belong to the basins of some of the tributaries of the Northern Dvina, such as the Yumizh and the Ludonga, and drain to the northeast.
Most of the district is covered by coniferous forests (taiga).
History
The area was populated by speakers of Uralic languages and then colonized by the Novgorod Republic. After the fall of Novgorod, the area became a part of the Grand Duchy of Moscow. Historically, it was a part of Vazhsky Uyezd, a vast area including almost all of the basin of the Vaga River. In the course of the administrative reform carried out in 1708 by Peter the Great, the area was included into Archangelgorod Governorate. In 1780, the governorate was abolished and transformed into Vologda Viceroyalty. Vazhsky Uyezd was split, and the area of the current Ustyansky District became a part of the newly established Velsky Uyezd. In 1796, Velsky Uyezd was transferred to Vologda Governorate and remained there until 1929, when several governorates were merged into Northern Krai. On July 15, 1929, the uyezds were abolished, and Velsky Uyezd was split into Velsky, Verkhovazhsky, and Ustyansky Districts. The administrative center of Ustyansky district became the selo of Shangaly. Ustyansky District became a part of Nyandoma Okrug of Northern Krai.
In the following years, the first-level administrative division of Russia kept changing. In 1930, the okrug was abolished, and the district was subordinated to the central administration of Northern Krai. In 1936, the krai itself was transformed into Northern Oblast. In 1937, Northern Oblast was split into Arkhangelsk Oblast and Vologda Oblast. Ustyansky District remained in Arkhangelsk Oblast ever since.
On September 26, 1975, the administrative center of the district was transferred from Shangaly to Oktyabrsky, but it took some time before all of the district services were moved.
From 1924 to 1959, Cherevkovsky District existed, with the administrative center in the selo of Cherevkovo, initially in Northern Dvina Governorate. On September 11, 1959, the district was abolished and split between Krasnoborsky, Verkhnetoyemsky, and Ustyansky Districts; the administrative center Cherevkovo became a part of Krasnoborsky District.
