The reservoir was formed as part of the building of the Aurland Hydroelectric Power Station in the 1960s and 1970s when a rock-fill dam was built at the end of the lake Viddalsvatnet. After damming the level of Viddalsvatnet was raised to include the two upstream lakes Liverdalsvatnet and Fretheimsdalsvatnet, and they now form one 8-kilometre (5.0 mi) long contiguous lake. Viddalsdammen receives water through an extensive system of water tunnels that extends around the entire Aurland valley.
