Northern Krai
In 1929, several governorates, including Vologda Governorate, were merged into Northern Krai. On July 15, 1929, the uyezds were abolished, and Velsky Uyezd was split into Velsky, Verkhovazhsky, and Ustyansky Districts. Verkhovazhsky District became a part of Nyandoma Okrug of Northern Krai.
