Founded in 1910, Paraskovyevka () was a farming settlement located to the southwest of the Belenkoye lakeshore. It is known that in 1928 the village had a population of 297 people (164 men and 133 women) and that most of them were of Ukrainian origin. However, official data regarding the subsequent abolition of the settlement and the fate of its inhabitants are lacking.
Nowadays the ruins of the houses of Paraskovyevka and other vestiges of former habitation, can still be seen, but the circumstances in which the village was abandoned remain a mystery.
