Вологодская губерния
On July 15, 1929 All-Russian Central Executive Committee by a decree abolished Northern Dvina Governorate and established the Northern Dvina Okrug, which was a part of Northern Krai. The Okrug had the same territory as the abolished governorate, with the addition of Brusnovolovsky Selsoviet from the former Totemsky Uyezd of the Vologda Governorate. The Okrug administration was located in Veliky Ustyug.
