When the reservoir was created, the waters submerged a small village and all the inhabitants had to be evacuated. For the production of hydroelectric power, it was decided to exploit the between lakes of Resia di Curon and San Valentino alla Muta. The creation of a large dyke unified the first two previous lakes and submerged the settlements of Curon and parts of Resia, as well as the former settlements of Arlung, Piz, Gorf, and Stockerhöfe. The inhabitants of these villages were forced to leave their homes and land. In the summer of 1950 the project was completed, the buildings destroyed and finally submerged in water. Only the Romanesque church tower, dating back to the 14th century, was saved because it is placed under monument protection.
Depending on the water level, the upper part of the bell tower is still visible today. The event is shrouded in many legends, but not only for this reason the lake is a popular destination for trips and excursions.
Legend has it that on certain days you can still hear the bells of the bell tower ringing from the bottom of the lake
