Sevvostlag (Russian: Северо-восточные исправительно-трудовые лагеря, Севвостлаг, СВИТЛ, North-Eastern Corrective Labor Camps) was a system of forced labor camps set up to satisfy the workforce requirements of the Dalstroy construction trust in the Kolyma region in April 1932. Organizationally being part of Dalstroy and under the management of the Labor and Defence Council of Sovnarkom, these camps were formally subordinated to OGPU later the NKVD directorate of the Far Eastern Krai. On March 4, 1938, Sevvostlag was resubordinated to the NKVD GULAG. In 1942 it was resubordinated back to Dalstroy. In 1949 it was renamed to the Directorate of Dalstroy Corrective Labor Camps (Управление исправительно-трудовых лагерей Дальстроя). In 1953, after the death of Joseph Stalin, with the reform of the Soviet penal system, it was again resubordinated to Gulag and later reformed into the Directorate of Far Eastern Corrective Labor Camps Управление Северо-восточных исправительно-трудовых лагерей, УСВИТЛ (USVITL).
The inmates served on all Dalstroy projects, the major ones being gold mining and road construction, including the infamous Kolyma Highway.
Sevvostlag was the sole administration for the whole system of the forced labor of Dalstroy. The numerous labor camps usually mentioned for Kolyma and Dalstroy were formally referred to as subcamps ("camp subdivisions", лагерные подразделения) attached (but not subordinated) to the corresponding production units. Until the 1950s the only exceptions were camps on the periphery of Kolyma, which while servicing Dalstroy, were either detached from or attached to Sevostlag at various times.[1]
From 1945 to 1949 there was a subcamp for Japanese prisoners of war in Magadan, which held 3,479 prisoners by January 1, 1949.[1]
The management was initially headquartered in the Srednikan settlement (now Ust-Srednekan, Magadan Oblast). It was moved to the Nagayev Bay, and eventually to Magadan.
