The lake was constructed by the Urartians during the reign of king Rusa II (685-645 BC). For that, a small river was blocked with two dams to create the reservoir which served to ensure a constant water supply for the capital Tushpa and irrigate the surrounding Van plan throughout constructed water channels.
