The Lai da Burvagn is a reservoir on the Julia in the Burvagn fraction in the canton of Graubünden . The lake, with an area of four hectares, is operated by the Mittelbünden power plants and serves as a compensation basin for the Tinizong headquarters and as a water intake for the Tiefencastel West headquarters .
The dam's heavyweight wall was put into operation in 1949 together with the Tiefencastel West machine house. From 1954 he also took over the function of the equalization basin for the newly opened Tinizong headquarters , which processes the water from the Lai da Marmorera . Since 1971, part of the underwater from Tinizong has been led in a tunnel directly to Tiefencastel, so that not all of the water from the Marmorera Lake flows through the Lai da Burvagn.
