A sequence of administrative reforms followed. In 1781, Olonets Oblast was transferred to Saint Petersburg Governorate, and in 1784, it was transformed into an independent administrative unit, Olonets Viceroyalty. In 1799, Olonets Viceroyalty was abolished and divided between Novgorod and Arkhangelsk Governorates. Lodeynopolsky Uyezd was merged into Olonetsky Uyezd. In 1801, Olonets Governorate was established, and in 1802, Lodeynopolsky Uyezd was restored. The northern part of the district belonged to Lodeynopolsky Uyezd of Olonets Governorate. In 1922, Olonets Governorate was abolished, and Lodeynopolsky Uyezd was transferred to Petrograd Governorate (later Leningrad Oblast).
