Sevvostlag

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.

In 1949 it was renamed to the Directorate of Dalstroy Corrective Labor Camps (Управление исправительно-трудовых лагерей Дальстроя).

The inmates served on all Dalstroy projects, the major ones being gold mining and road construction, including the infamous Kolyma Highway.

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.
