The local tradition keeps two legends related to the lake origin:
According to the legend a robber, who stayed in the cave of Suhardul Mare, had stolen from a fair in Ditrău and dragged along the beautiful Ferenc Anikó. The girl cried and implored the help of the cave ghost, when the walls of the cave opened and she escaped. When the robber came around, he banged the cliff with his bludgeon so strongly that the mountain collapsed and closed the valley burying under itself the robber.
